BLANK PAGE

1.0 Introduction
Chevron Gulf of Mexico business units value the safety of all
workers and the protection of our environment. Our
company is committed to having incident-free operations
(IFO). We can only achieve this by working as a team with
our contractors.
The following terms are used in this handbook to describe
the contractor company and personnel mentioned in the
guidelines:
Handbook Terms
Contractor

A contractor is defined for the
purposes of this document as any
company or individual which by
contract, subcontract, or purchase
order performs work or provides
services or equipment to or for
Chevron.

Contractor
Supervisor/
Person Leading
Work (PLW)

This individual represents the
contractor company that supervises
the work of a contractor or
contractors.

This handbook provides guidance and a minimum set of
expectations for Chevron employees and contractors
regarding contractor work performed for Chevron. As the
contractor, you are required to follow the policies and
procedures established by the contractor’s company in
addition to any of Chevron’s site-specific policies. This
handbook is intended to supplement, not replace, the
contractor’s company safety program, which the contractor
is required to implement. In the event of a conflict between
this handbook and the contractor’s company safety
program, the more stringent rule shall apply. The contractor
company’s contract with Chevron may be canceled, or an

Contractor Handbook | 1

individual may be requested to leave Chevron premises
and not return if the guidelines of this handbook are not
followed.
Chevron is continuously looking for ways to improve our
health, environment, and safety (HES) programs. To
communicate feedback for improvement or changes to this
document, please access the Chevron external Gulf of
Mexico Contractor Safety website at https://upstream.
chevron.com/contractorgom/.

1.1 Operational Excellence
Operational Excellence (OE) is a Chevron system for
managing the areas of health, safety, environment,
reliability, and efficiency and is one of our critical drivers
for business success. The contractor will be exposed to
Operational Excellence and our efforts to achieve incidentfree operations while working for Chevron. Both of these
goals are important to our business, and it is essential that
our contractors and their employees understand and are
familiar with them.
Operational Excellence is based on the ten tenets that
Chevron is committed to using to guide decision making,
work planning, and execution in all situations. It is our
expectation that contractors working under Chevron’s
operational control will abide by these tenets as well.
Chevron’s Operational Excellence Tenets of Operation
We Believe:

All incidents are preventable.

Two Key
Principles:

• Do it safely or not at all.
• There is always time to do it right.

1. Operate within design and
environmental limits.

ii2.

Operate in a safe and controlled
condition.

ii3.

Ensure safety devices are in place
and functioning.

ii

1.2 How to Use This Handbook
The intent of this handbook is to provide guidance to our
contractors and employees regarding Chevron’s
expectations of its contractor workforce. All of Chevron’s
contractors should have a copy of this handbook accessible
to them. The contents of this handbook should be reviewed,
discussed, and understood by contract personnel before any
work is performed for Chevron. If an HES issue arises that is
not addressed in the handbook or by the contractor’s own
safety program, you must ask for guidance from the
contractor representative or a Chevron representative.

Contractor Handbook | 3

Contractor health, environment, and safety orientation
meetings are available to supplement this handbook. The
contractor may schedule an orientation by contacting the
Chevron person overseeing the work.
Remember:

Stop-Work Authority
It Is Your Responsibility
You Have the Authority
Zero Is Attainable
Your ideas and concerns are important. We always
comply with the Tenets of Operational Excellence shown
above. As an employee or contractor for
Chevron, you are responsible and authorized to stop
any work that does not comply with these tenets, and
there will be no repercussions to you. That is our
commitment to you.

2.0 Responsibility Overview
2.1 Chevron Employee Responsibilities
The following are Chevron employees’ key responsibilities
regarding this handbook:

• Be aware of the contractor handbook and its
requirements.

• Ensure that contractors are aware of these expectations
and have a copy of the handbook available.

• Ensure that all contractors working for Chevron are
meeting the expectations presented in the handbook.

2.2 Contractor Responsibilities
The contractor’s company is responsible for the contractor’s
employees’ safety and for ensuring that the contractor’s
employees perform their day-to-day work in a safe and
proper manner.
The contractor must read, become familiar with, and follow
the contents of this handbook and consult with the
contractor’s supervisor if the contractor has any questions
about its contents.
The contractor must become familiar with Chevron’s
requirements and expectations, many of which are
presented in this handbook. These guidelines are intended
to supplement, not replace, the contractor’s own safety
program. If Chevron’s procedures and the contractor’s
procedures conflict, the more stringent rule should
be followed.

2.3 Stop-Work Authority
Chevron is committed to following the Tenets of Operational
Excellence listed in Section 1.1 at all times. All contractors
are authorized to stop and are responsible for stopping any

Contractor Handbook | 5

work that does not comply with these tenets. It is Chevron’s
commitment that there will be no repercussions upon any
contractor for taking such action.
The contractor is empowered and expected to stop the work
of co-workers, Chevron employees, or other contractors if
any person’s safety or the environment are at risk. No
repercussions will result from this action.
If the contractor, the contractor’s employees, or
subcontractors are discouraged from exercising their
Stop-Work Authority (SWA) or are penalized for doing so,
they should report this action via the Chevron external Gulf
of Mexico Contractor Safety website at: https://upstream.
chevron.com/contractorgom/ or call the numbers
listed below.
If a contractor has a concern about a safety or compliance
issue, or wishes to provide a suggestion for improvement in
these areas, it is critical that the contractor’s comments are
heard and any resulting actions are communicated to the
contractor. Safety or compliance issues can be
communicated in one of these methods:

• Notification of supervisor/person in charge: Any safety







or compliance issue that arises should be brought to the
attention of the Chevron supervisor or representative.
Depending on the significance of the item, raising a
concern in this manner can be done verbally or in writing.
Chevron supervisors should respond to the contractor
with a description of how the concern will be resolved.

• Notification of BU HES manager: Any safety or





compliance issue that has not been resolved or agreed
upon by a contractor and respective Chevron
supervisor/representative can be raised to the Chevron
HES managers. Contractors may leave a phone or

6 | GOMBU and DWEP BU








email message, or a letter prefaced by the statement,
“I am reporting an HES concern for your review.” This
notification can be made anonymously. The HES manager
should then review the contractor’s concern and report
the outcome of the review to the appropriate BU
management.

• HES managers can be reached at the following numbers:
HES Managers

Numbers

Greater GOM HES Manager

985-773-6000

Gulf of Mexico BU HES Manager
(Covington)

985-773-6000

Deepwater and Exploration
Projects BU HES Manager
(Houston)

832-854-6000

• Chevron Hotline: If the contractor was unable to resolve







the HES issue using both steps and the contractor
believes a violation of HES policy or regulation exists,
the contractor can call the Chevron Hotline at
1-800-284-3015. Use of the Hotline will prompt an
external investigation from personnel outside the
respective business unit.

3.0 Chevron Workplace Principles

and Policies
3.1 Professional Conduct
Chevron respects every individual who works for our
company. We expect our employees and contractors to
conduct themselves in a professional manner. Horseplay,
practical jokes, and harassment are not allowed. No form of
harassment or fighting will be tolerated while on locations
under Chevron’s operational control. Depending on the
severity, additional repercussions, such as involvement of
regulatory agencies and law enforcement, may result.

3.2 Contraband: Drugs, Alcohol, Weapons,
Pornography



Any person under the influence of alcohol, controlled
substances, or any intoxicating substance is prohibited from
entering company premises, engaging in company business,
or operating company equipment; no pornography of any
kind may be displayed or stored on Chevron property.
Entry into or exit from any Chevron office or work location is
provided under the condition of the company’s right to
search any person, vehicle, or the personal effects of any
employee or contractor for illegal drugs, intoxicating
beverages, firearms, weapons, or pyrotechnics (e.g., BIC®
lighters). As a safety precaution, and to preclude the loss of
Chevron’s tools, materials, or equipment, authorized
representatives of Chevron may search those entering,
working in, or exiting Chevron locations without prior
announcement.
Chevron’s drug and alcohol policies and procedures are fully
explained in the contractor’s contract.

8 | GOMBU and DWEP BU



3.2.1 Alcohol









Chevron prohibits the
unauthorized use, possession,
distribution, purchase, or sale of
alcohol while on company
premises, conducting company
business, or operating company
equipment.



3.2.2 Illegal Drugs






Chevron prohibits the use, possession, distribution,
purchase, or sale of illegal drugs while on company
premises, conducting company business, or operating
company equipment.



3.2.3 Prescription Drugs





















If a contractor brings prescription
drugs into a Chevron facility, the
medication must be in the bottle
or container in which it was
originally dispensed and must be
prescribed to the individual.
The contractor’s employees shall
report the use of medication to
the supervisor employed by the contractor. That
contractor supervisor should report to the Chevron
supervisor, in general terms, that one of the contractor’s
employees on location is using medication and has
reviewed such use with the contractor’s medical
sources, and that the contractor’s employee has been
cleared for work. If the contractor’s supervisor cannot
assure the Chevron supervisor that these steps were
taken, or if the worker appears to be impaired or
endangering himself or herself or others, said worker
may be removed from Chevron premises.




Use of a prescription or over-the-counter medication is
permitted only if such use does not have side effects

Contractor Handbook | 9






that could adversely affect the contractor’s work
performance. Contractors should consult with their
physician before taking any medications that may
interfere with their ability to work safely.






Chevron prohibits the use, possession, distribution,
purchase, or sale of any controlled substance while on
company premises, conducting company business, or
operating company equipment.



3.2.4 Internet Prescription Drugs






It is unlawful to use a controlled substance or other
prescription drug without a valid prescription. A
contractor must have a legally valid prescription to take
a controlled substance.













Under applicable law, an employee must have a doctor-
patient relationship with the doctor prescribing the
controlled substance. Various state and federal
authorities establish that a prescription issued outside
a legitimate doctor-patient relationship, such as an
“Internet prescription” that is based on an online
questionnaire and review by a doctor who has not
examined the patient, is invalid. Such prescriptions are
also unacceptable under the Department of
Transportation’s drug testing regulations. (Interpretive
guidance to 49 CFR 40.141.)





A contractor who uses or possesses a controlled
substance with an invalid prescription is in violation of
Chevron’s policy prohibiting controlled substances.

3.2.5 Explosives and Firearms






Chevron prohibits the use, possession, transportation, or
sale of unauthorized explosives, unauthorized flammable
materials, firearms, or other weapons while on company
premises, engaged in company business, or operating
company equipment.

10 | GOMBU and DWEP BU

3.3 SafeGulf
All personnel who work a rotational position in the offshore
Gulf of Mexico and all personnel that will or may travel there
more than three trips per calendar year are required to be
SafeGulf c00ertified.
SafeGulf is a program to ensure that all workers in the Gulf
of Mexico are trained to a set of minimum requirements for
HES awareness. This training is not meant to take the place
of regulatory and company training requirements, and
additional training may still be required for specialized and
regulatory controlled work.
Upon arrival at a Chevron shorebase, all personnel must
show a government-issued picture ID to enter the shorebase.
SafeGulf certification is required for travel to any offshore
facility for anyone who travels more than three times a year.
Specific details about the content of the SafeGulf training
and training providers are available on the SafeGulf website
at http://www.safegulf.com.

3.4 Transportation Worker Identification Card
Certain Chevron facilities are regulated under the Maritime
Transportation Security Act (MTSA) of 2002. This act
requires Chevron to implement Coast Guard-regulated
offshore and shorebase security plans for facilities that
meet certain oil, gas, or chemical production or
transportation thresholds. A Transportation Worker
Identification Card (TWIC®) is a biometric security credential
(card) issued to employees, both Chevron and contractor,
who need unescorted access to offshore and shorebase
facilities that are required to implement a U.S. Coast Guard
(USCG) Facility Security Plan (FSP).
The following guidance applies to TWIC.
a) All contractors who are permanently assigned to
Chevron’s offshore facilities that have Coast Guard-
approved facility security plans must obtain a TWIC.

Contractor Handbook | 11

b) All contractors who have the potential to work on or
visit Coast Guard-regulated facilities for any purpose
and need unescorted access to the facility must obtain
a TWIC.
c) Employees and contractors without a TWIC may still
work and visit Chevron Coast Guard-regulated security
facilities, but they must obtain permission from the
facility person in charge before arriving because the
facility will be required to escort the employee during
the visit. (Employees without a TWIC must be escorted
by a facility employee who has a TWIC.) As a general
rule, GOM facilities are not staffed to provide security
escorts and may not be able to accommodate visitors.
d) Employees and contractors without a TWIC are required
d) to contact the person in charge before arriving to make
d) escort arrangements. This also applies to all pilots,
including Chevron pilots. If a pilot wants unescorted
access to these locations, then they must obtain a TWIC.
TWICs for these facilities will be checked at the shorebase
and heliport during crew changes and at the facilities as
personnel arrive.

3.5 Housekeeping
It is the contractors’ responsibility to keep their work areas
clean, orderly, and in a condition conducive to safe work
while under Chevron’s operational control. The contractor
will:

• Keep all work areas, walking surfaces, handrails,
equipment, tools, and life-saving and fire-fighting
equipment clean and free of obstructions.

• Store tools or tie them off, so they do not cause a hazard
to people in the surrounding area.

• Use only commercial fire-safe solvents for cleaning. A
safe solvent is a class IIIA liquid; it has a flash point above
140°F and below 200°F. Prohibited cleaning agents


12 | GOMBU and DWEP BU

include, but are not limited to, gasoline, diesel, and methyl
ethyl ketone (MEK). Questions on appropriate solvents
should be directed to the Chevron person in charge.

• Segregate wastes, including discarded oily rags, from
regular trash.

• Use plastic buckets appropriately; they should not contain
any hydrocarbons or flammable items.

• Appropriately label all loose materials, small tools, and
other small objects with the name of the owner before
use or transport over offshore waters.

• Properly label all containers (e.g., spray bottles, jugs) with
name of substance contained.

3.6 Smoking
All Chevron buildings and living
facilities are designated as
“nonsmoking” areas, except for areas
specifically designated for smoking.
Chevron will provide, or request the
contractor to designate, a facility for
smoking in a separate building with
ventilation to the outside or a
separate room with outside ventilation or, if there is no
alternative, an appropriate, designated outside smoking
area.
Smoking is permitted only in designated smoking areas.
Smoking is not allowed in any common use area, such as
galleys, offices, restrooms, and laundry rooms, unless
duplicate “smoke-free” common use facilities are provided.
During personnel transport, smoking is not allowed in
common use areas, such as passenger seating areas.
Smoking is allowed in the wheelhouse of a vessel as long as
the area is well ventilated, the secondhand smoke is not
circulated throughout the passenger seating area, and there
is not a more stringent smoking policy imposed by the
vessel owner/operator.

Contractor Handbook | 13

3.7 Fishing Policy
Chevron discourages, but does not prohibit, employees and
contractors from fishing during nonworking hours while
onboard any Chevron offshore facility. Certain facilities, at
the supervisor’s discretion, may entirely forbid fishing.
Before beginning to fish, employees and contractors must
determine if it is permissible to fish at that facility. While
fishing, personnel must follow all federal, state, and local
jurisdictions’ fishing regulations, along with any Chevron
site-specific rules. Fishing regulations may require licenses,
possession limits by species or quantity (creel) and size, and
cleaning stipulations.

3.8 Language Requirements
All workers must be able to read or understand the posted
warning signs while working at a location under Chevron’s
operational control. Except on foreign-flagged vessels such
as barges or rigs, one translator will be assigned to each
non-English speaker while work is conducted. No more than
one non-English speaker will be assigned to a translator. If a
translator is needed, the contractor must notify the Chevron
work owner, who must notify the field supervisor before
work begins. Where crew members predominately speak a
language other than English and warning signs are posted in
that language, the number of translators required will be
determined by the Chevron work owner and documented in
a mitigation plan.

3.9 Security
Contractor companies shall be responsible for their own
equipment and accountable for controlling the actions of
their employees while working at locations under Chevron’s
operational control. Chevron is not responsible for lost or
stolen articles. Contract employees are discouraged from
bringing large amounts of cash or other valuables of a
financial or personal nature to work sites. If they choose to
do so, however, it is their own responsibility to keep these

14 | GOMBU and DWEP BU

items adequately secured. Company and contract employees
are encouraged to practice good Security Awareness and
Vigilance behaviors and alert company personnel to any
suspicious persons or witnessed behaviors.
Chevron is required by federal regulations to develop and
implement plans to address security risks related to
transporting and storing hazardous materials. The Chevron
Gulf of Mexico Facility Security Plan has identified specific
areas of our shorebase and all our offshore facilities as
restricted areas that potentially store or transport
hazardous materials.
Contractors are included in the Facility Security Plan. Part of
this plan seeks confirmation of employee information for
those who have access to and/or handle hazardous
materials. Specifically, contractors who enter restricted
areas must show valid, government-issued picture
identification, and their company will be required to perform
pre-employment background screenings. These screenings
must include recent employment history, references,
citizenship/alien status, verification of identity, and Social
Security participation, as well as a review of any state or
federal criminal records.
Personnel that are traveling offshore will be required to
check in with security at the heliport with a picture ID, and
the identification number on that ID is recorded. Please
ensure that when traveling to one of the deepwater rigs, you
have a current identification card or driver’s license.
All contractors who are not U.S.
citizens or permanent U.S.-resident
aliens possessing an Alien Registration
Card (Green Card) will be considered
Foreign Nationals (FN) and will have
to be cleared by Chevron and the U.S.
Coast Guard before being allowed to
visit a Chevron facility or travel

Contractor Handbook | 15

offshore. Additional details regarding foreign nationals are
available in BU-specific processes and procedures.

• Prior to an FN contractor’s arrival at any DWEP or GOM
facility, the FN contractor’s employer shall notify the
Chevron work owner that the contractor is an FN.

• Before scheduling a trip to an offshore facility, the
FN contractor’s employer shall request the USCG to
issue a Letter of Determination (LOD) to the contractor.

• Prior to the arrival of an FN contractor at any DWEP or






GOM facility, the responsible Chevron work owner shall
complete a Chevron North America Exploration and
Production (CNAEP) Company Visiting Foreign National
Form and send it to the CNAEP Export Control
Officer (ECO).

• When the FN contractor arrives at the shorebase or
airport to go offshore, the contractor shall possess a
passport with a valid U.S. visa and a copy of the LOD
issued by the USCG. The CNAEP ECO must then clear
the contractor.

3.10 Behavior-Based Safety Process
Contractor companies are required to have their own
behavior-based safety (BBS) process. This process must
include:

• A data sheet with critical behaviors – Critical behaviors
listed on a data sheet (observation card) should be pulled
from historical incident data listing behaviors that led to
those incidents.

• Training on the observation process – Appropriate
personnel will be trained on the established observation
process.

• Feedback after observations – Upon completing an
observation, the observer is expected to have a
discussion with the observed to give feedback.

16 | GOMBU and DWEP BU

• Data collection and trend analysis – The contractor will
have a process to collect the data from each observation
and perform trend analysis on the data collected.

• Action planning – Once trend analysis is complete, the
contractor shall create appropriate action plans to
address unsafe behaviors.

• A step to follow up on action plan – Action plans are
carried out over the course of a set time period. Follow-up
is necessary to ensure the closure of all actions listed with
the action plan.
Contractors acting as Chevron representatives are expected
to follow the applicable BU BBS process.

3.11 Orientation of Visitors at Offshore
Locations



All personnel are required to sign a login sheet when
arriving at a Chevron site. When arriving at a Chevron
location for the first time, individuals are required to attend
an orientation meeting that will cover emergency
procedures, including the Emergency Evacuation Plan (EEP)
and site-specific information.

3.12 Short-Service Employee Policy
A short-service employee (SSE) is any contractor with fewer
than six months of experience in the same job type or with
the contractor’s present employer. Contractors who quit and
return to the same company and the same job type within
one year are deemed to satisfy the requirements.
Specific policy requirements:

• Notification
–  The contractor must complete the SSE form for each
–  SSE assigned to perform work at a Chevron location.
–  The form must be submitted to the Chevron
–  representative who hired the contractor’s
–  personnel, and it must be approved 24 hours before
–  the SSE arrives on Chevron property.







Contractor Handbook | 17

–  The contractor will fax this form to the Chevron

location supervisor before arriving at the work

location if job mobilization is within 24 hours of the
request for work. If an SSE for whom an SSE form has
–  not been submitted arrives on Chevron property, the
–  onsite Chevron representatives may send the SSE
back to shore at the contractor’s expense. All SSEs
must carry this form on their person at all times
while on Chevron property.

• Chevron SSE crew makeup requirements:
–  Single-person “crew” cannot be an SSE.
–  Two-to-four-person crews can have only one SSE
per crew.

–  Five-or-more-person crews shall not exceed 20% SSEs.
–  Crews with more than 20% SSE personnel are only
permitted upon the submission of a written

variance approved by the Chevron representative.

• Identification
–  All SSEs must be identified with a high-visibility
orange hard hat. (This high-visibility color is not the
same as orange.)

• Mentoring
–  Mentoring Process: The contractor must assign an
onsite mentor to each SSE. A mentor can be

assigned to only one SSE per crew. Each mentor
must closely supervise the SSE to ensure that the
SSE does not perform tasks for which they are not
properly trained. Land transportation contractors
are exempt from the onsite mentoring requirement.
–  Mentoring: Each SSE’s work will be closely
monitored for a six-month period. During that
period, the SSE must demonstrate a good working
knowledge of the contractor’s and Chevron’s HES
policies. The contractor may require any employee
having a recordable safety incident within this
time to repeat the six-month introductory period.

18 | GOMBU and DWEP BU

• Subcontractors
–  Chevron GOMBU contractors will manage their
subcontractors in alignment with this policy.



• Naturally Occurring Radioactive Material (NORM) Areas
–  No SSEs are allowed to work within designated
NORM work areas.



3.12.1 Contractor Short-Service
Employee Form
The Chevron Contractor SSE Form consists of a section
that captures information on the individual SSE and a
variance section that will be filled out whenever any
element of the SSE Policy (listed above) cannot be met.
The information section must be filled out for all SSEs
and submitted at least 24 hours before SSE arrival for
approval or rejection by the Chevron location supervisor.
In the event that a variance is required, it will be filled
out and submitted to the Chevron location supervisor
who has authority to approve or deny any variances on
his location.
Approved SSE forms are available on the Chevron
external Gulf of Mexico Contractor Safety website at:
https://upstream.chevron.com/contractorgom/.

Contractor Handbook | 19

3.13 Root Cause Analysis/Incident
Investigation





Contractors are required to conduct, and in some cases may
be asked to lead, a root cause analysis (RCA) team. Root
cause analysis investigations are required for:
• Any accident resulting in an Occupational Safety and
Health Administration (OSHA)-recordable injury.
• Any spill of one barrel or greater (GOMBU) and all oil and
chemical spills (DWEP BU).

• All incidents that exceed national pollutant discharge





elimination system (NPDES) guidelines. In addition, DWEP
BU requires an RCA for any NPDES sheen, even if the
sample passes the lab test, or any NPDES lab test that is
above the monthly average.

• All fires.
• All preventable motor vehicle crashes (MVCs) that take
place in a Chevron company car.

• Any “near miss” or minor incident that has the potential
to result in a serious injury, oil spill, property loss, fire,
or MVC.

• Incidents that occur frequently, at the request of the GOM
management team.

• Any significant financial incident.
• Marine vessel operators. An incident investigation and
root cause analysis is required where a notice of marine
casualty, 46 CFR 4.05, requires reporting an incident to
the U.S. Coast Guard.
RCA investigations shall include, but are not limited to:

• A description of the event
• A determination of the actual and potential loss or losses
• A list of the root causes of the incident
• An evaluation of the risk of recurrence

20 | GOMBU and DWEP BU

• A list of system controls and/or process changes to
reduce the risk of recurrence

• A plan to communicate fully any lessons learned
All RCAs completed for incidents on Chevron property will
be shared with the contractor’s Chevron representative as
soon as possible. Chevron may request to participate on all
incidents requiring investigations while under operational
control.
In situations where an incident involves multiple contract
companies or contract and Chevron personnel, Chevron may
commission a team composed of personnel from all affected
companies.
Any contractor who has incurred an OSHA-recordable injury
or illness while working for the Chevron DWEP or GOMBU
must schedule a meeting with the appropriate Chevron vice
president or designee to review the details of the incident
and any lessons learned. This meeting should be scheduled
within a reasonable time frame after the RCA is complete.

3.14 HES Ratings Overview
During the qualification process, contractor work scope will
be evaluated by the Supply Chain Management group to
determine whether a contractor is required to have an HES
rating. Contractors requiring an HES rating will be assigned
a rating of A-F based on the following six elements:
1. Total Recordable Incident Rate (TRIR)
2. Safety questionnaire
3. HES audits
4. Field competency verifications
5. Field feedback forms
6. Working relationship
Additional information on Chevron’s Contractor Safety
Management process may be found at https://upstream.
chevron.com/contractorgom/.
Contractor Handbook | 21

3.15 Cell Phone Usage While Operating a
Motor Vehicle
In accordance with the Chevron Cell Phone Policy,
contractors may not use a cell phone while driving or
operating heavy equipment while on Chevron locations or
while operating a Chevron-owned or -rented vehicle.
Contractors are discouraged from other forms of
“multitasking,” such as using two-way radios and pagers,
eating, or taking notes, while operating a motor vehicle.

3.16 Management Field Visits
Strong leadership is a critical success factor for any safety
program. Contractor management is required to visit work
sites periodically.

3.17 Subcontractors
Primary contractors will be held accountable to ensure that
their subcontractors are held to the same standards as their
employees. This includes ensuring that subcontractors are
qualified to perform the work and are meeting Chevron’s
expectations while working under Chevron’s operational
control.
For ongoing work, the contractor is required to notify the
Chevron work owner when the contractor will be using
subcontractors.
For project proposals, contractors are required to submit a
subcontracting plan, including:

• Products and services to be subcontracted
• Selection criteria to be used to select subcontractors
• Plans to ensure HES performance from subcontractors

22 | GOMBU and DWEP BU

4.0 Emergency Procedures
4.1 Medical Coverage
Contractors are responsible for providing medical coverage
as appropriate for their scope of work. This may range from
first aid-trained personnel to licensed paramedics. In the
event that medical coverage provided by the contractor is
not available, Chevron will take necessary and reasonable
steps to ensure that care is provided to contract employees
working on Chevron property. Chevron strategically deploys
emergency medical responders (EMRs) at various locations
in the Gulf of Mexico.
Proximity to additional medical support or hospital facilities
should be considered when determining appropriate
medical coverage.

4.2 Medical Emergency Transportation

Process



In the event of a medical emergency, the contractor’s
Chevron representative will ensure transportation of the
injured person to shore. Injured personnel sent in for
medical assistance/evaluation should be accompanied to the
medical facility. Depending on medical provider availability
or severity of injury, a nonmedical provider may accompany
the injured party. This person should have the authority
from the contractor to authorize treatment for the injured
employee (e.g., foreman or supervisor).
The contractor’s company should have a representative
meet the injured person upon arrival to ensure medical care
is appropriately provided.

4.3 Hurricane Evacuation Action Plan
Chevron coordinates the safe evacuation of all personnel
working on Chevron offshore facilities and shorebases. This

Contractor Handbook | 23

includes contract employees working on a Chevron facility.
Chevron’s evacuation process and plans are contained in the
Chevron GOM Operational Excellence Manual.
Contractors are responsible for developing and maintaining
plans to:
1. Safely evacuate contract employees who are not working
on a Chevron offshore facility or shorebase.
2. Safely secure contractor equipment or assets located or
staged at Chevron shorebases. This includes vessels tied
at Chevron piers.
3. Safely secure (or move) contractor offshore equipment
or assets not located or staged on Chevron offshore
facilities.

4.4 Damaged Facility Assessment and

Boarding Process



Guidelines exist for personnel boarding facilities for the
purposes of performing damage assessments, regulatory
compliance, or other work on platforms and caissons after
storm events or other events that:

• May have compromised the structural integrity of the
facility or facilities.

• May have restricted access/egress to the facility due to
damage to boat landings and swing ropes and/or heliports.

• May have created safety hazards (open holes, missing
handrails, damaged vessels, etc.) on the facility or
facilities.

• May have created hazards by moving or compromising
production equipment.
No one shall be allowed on any structure identified as being
in a noncompliant condition until a hazard mitigation plan
has been prepared and approved by the Operations manager
to maximize the safety and security of our employees and
contractors as well as anyone who may seek refuge there.

24 | GOMBU and DWEP BU

Boarding Assessment personnel may board such facilities
only after an Initial Assessment has been done as described
in Section 4.4.4 and permission is granted by the Operations
supervisor.



4.4.1 Facility Status Definitions



4.4.1.1 O
pen





Facilities that are deemed “Open” are considered open
for normal operations and do not require a mitigation
plan for boarding.



Open facilities must meet the following criteria:

• All damaged or hazardous areas are sufficiently
mitigated or isolated to Chevron GOM standards
including:

–  Significant structural damages repaired or deemed
safe by engineering analysis
–  Two functional means of egress

–  All open holes barricaded per GOM Open Hole
standards

–  All missing and damaged handrails mitigated/
barricaded to Chevron standards (see Guidelines
for Guarding Deck Openings)
• Other hazards (spills, loose or hanging items, etc.)
cleaned or secured


4.4.1.2 Closed









Closed facilities are defined as those for which access
to the facility is restricted and/or hazards exist that
require one or more persons to mark, barricade,
protect, remove, and/or repair the hazard enough to
protect personnel and the environment. Closed facilities
require a mitigation plan for boarding. This plan must be
signed off by the Area Operations manager.



Contractor Handbook | 25



4.4.2 Status Changes


Status Changes From Open to Closed

Automatic – Facilities will automatically be given the
“Closed” status for the following reason:
• The facility is in an area that experiences sustained
hurricane-force winds. This is the same criterion the
Bureau of Ocean Energy Management, Regulation, and
Enforcement (BOEMRE) uses to shut in remote-
operated facilities.
Discretionary – Facilities may be given the “Closed”
status at the discretion of the Operations supervisor,
Offshore/Onshore Installation manager (OIM), or
Operations manager:
• After a significant event that may have
compromised safety or structural integrity of the
facility.
• After a significant issue is identified in a Job Safety
Analysis (JSA) review or through the use of Stop-Work
Authority.
Status Changes From Closed to Open



Changes from Closed to Open may occur only after the
following is completed:



• The facility meets all Open criteria in Section 4.4.1.1.



• Operations supervisor approval is obtained.



4.4.3 Damage Assessments





In conducting these assessments, care must be taken
not to expose ourselves or others to the risks we seek
to identify.



4.4.4 Initial Assessments





Initial Assessments are made from either helicopter or
boat and do not require a mitigation plan, because the
facility will not be boarded.

26 | GOMBU and DWEP BU

Observations should be made of the following items:
• Platform (i.e., listing or missing)
• Heliports
• Boat landings and swing ropes


• Stairways

• Grating and handrails
• Major piping and production vessels
• Spills or sheens





In the event the assessment team observes a condition
that requires immediate action (i.e., continuing
pollution); personnel will relay the situation to the
supervisor or manager to discuss actions to be taken.



4.4.5 Boarding Assessments




Boarding Assessments will be made with an objective
to obtain further damage assessments.



Before boarding, personnel must do the following:

• Obtain Operations supervisor approval to board
facility.
• Review the Initial Assessment as part of their JSA and
pre-job safety meeting.


• Perform a visual assessment to:

–  Confirm Initial Assessment.
–  Identify additional hazards/risks.



Once on board, boarding personnel must do the
following:

• Actively use the BBS process and Stop-Work
Authority.
• Visually observe the levels overhead and below
before changing levels.


Contractor Handbook | 27

• Implement hazard mitigations within their
capability (marking, tying-off, barricading open
holes, blocking stairwells, top and bottom).
Boarding Assessments will recommend facility status
as “Open” or “Closed” as defined in sections 4.4.1.1
and 4.4.1.2.
All assessments are to be submitted to the designated
coordinator for each area.

4.4.6 Methods to Secure Closed Facilities





All facilities that are deemed “Closed” through the
assessment process will be secured to prevent access
(by employees, contractors, and the general public) to
those facilities until they are made safe.

Ways to install barriers include, but are not limited to:
• Removing or pulling up and tying off all swing ropes as
appropriate
Caution: Do not leave yourself without egress or
without a way to board under a
Boarding Mitigation Plan later.
• Installing locking-out clamps
on all stairways:
–  Leading up from the boat
landing
–  Leading down from the
heliport
• Marking the heliport as closed
as per Chevron Aircraft Operations Guidelines
• Posting appropriate signage on Stairway Lockout
Clamps


28 | GOMBU and DWEP BU



4.4.7 Accessing Closed Facilities






Access to Closed facilities will only be allowed with the
development of a Boarding Mitigation Plan for each
specific facility. The Operations manager must approve
all Boarding Mitigation Plans for each boarding party.

4.4.8 Boarding Mitigation Plans




Boarding Mitigation Plans will be documented on the
Boarding Mitigation Plan Template. All mitigation plans
will include the following minimal requirements:

• All boardings must be done by two or more personnel.
No single-person boardings are permitted.
• Complete the Permit to Work form and any

necessary Safe Work Practices (JSA, Hot Work
Permits, Isolation of Hazardous Energy Form, Lifting
Plan, Fall Protection and Rescue Plan, etc.) as needed
for the scope of work to be performed. Review listed
hazards with personnel boarding the platform.
• Communications (company radio, satellite phones, etc.)
will be maintained while on board. Establish location
and contact information for nearest emergency
medical responders.
• Advise the Field Operations supervisor or the
designated person in charge (PIC) before boarding
the structure.
• In the event additional hazards are found, they will be
mitigated and reviewed with the entire crew before
initiating work.
• Replace Platform Closed signs any time you depart
the platform.



4.4.9 Documentation




All Damage Assessments will be documented on the
appropriate forms:



• Initial Assessment Form

Contractor Handbook | 29



• Boarding Assessment Form



• Boarding Mitigation Plan Template

4.4.10 Boarding Assessment Personnel
• Review this process as part of JSA and pre-planning
for performing assessments.
• Review the hazards identified by the Initial
Assessment.


• Develop a Boarding JSA.

• Obtain Operations supervisor approval to board
facility.
• Proceed with caution as not all hazards may be
readily visible or evident.
• Complete the Boarding Assessment Form, and submit
it to the Operations supervisor.

4.4.11 Operations Representative or
Contract Representative






This will normally be the company or contract
representative in charge of the person(s) doing the
work. This person may be supervising several jobs or
could in certain circumstances be the person performing
the task.

• Review this process as part of JSA and pre-
planning for performing repairs.
• Review the hazards identified by the Initial and
Boarding Assessments.
• Develop a Boarding Mitigation Plan as necessary and
submit to the Operations supervisor for review.
• Advise Operations supervisor before boarding
facility.
• Proceed with caution as not all hazards may be readily
visible or evident.

30 | GOMBU and DWEP BU

4.5 Incident Reporting Procedures
Incidents are defined as identifiable and unintentional
deviations from planned operations, caused by factors that
may or may not be within Chevron’s span of control, that
result in an injury to an employee or contractor or cause
environmental consequences, property damage, or a near
miss that could have resulted in any of the above.
All incidents, near misses, property damage, spills, releases,
fires, harassment, and permit violations must be reported as
soon as possible to Chevron personnel. A Chevron incident
report must be completed and any statements needed for
the report must be taken at that time. Failure to report an
incident may result in termination of the contract.
Any contractor who has incurred an OSHA-recordable injury
or illness while working for the Chevron DWEP or GOM
business units must schedule a meeting with the appropriate
Chevron vice president or designee to review the details of
the incident and any lessons learned. This meeting should
be scheduled within a reasonable time frame after the RCA
is complete.
If an injury classification changes over time, the contractor
is required to notify Chevron and update their Management
System Questionnaire (MSQ). Failure to do so may result in
termination of the contract.

4.6 Oil Spill Response Plan and Notifications
Chevron’s emergency management team will coordinate
responses to oil or hazardous material (HAZMAT) spills that
originate from Chevron offshore and shore-side facilities or
assets. This includes complying with government agency
planning requirements and notifying the National Response
Center (NRC) and all other applicable government agencies
of oil and HAZMAT spills that originate from Chevron
property or assets.

Contractor Handbook | 31

Contractors who observe or discover a spill from a Chevron
facility or asset will take the following actions:
1. Safety first – Ensure the safety of all personnel. Anyone
who observes the spill should act carefully, cautiously,
and reasonably.
2. Notify the contractor’s supervisor and the Chevron
person in charge.
3. Control the source – Qualified personnel, when feasible,
should take actions that may include, but are not limited
to:


• Shutting in the well(s) and/or vessel(s)

• Closing the surface and/or subsurface (automatic or
manual) safety device(s)


• Actuating emergency shutdown (ESD) device(s)

• Actuating blowout prevention (BOP) assembly and well
control system(s)
Contractors are responsible for developing oil and HAZMAT
response plans that meet agency regulations for spills that
originate from their property, facilities, or assets, including
vessels. Contractors are therefore responsible for managing
and responding to all oil and hazardous material spills that
originate from their property, facilities, vessels, or assets.
This includes notifying the NRC and other appropriate
agencies of oil and hazardous material spills that originate
from contractor property or assets, including vessels.

4.7 Emergency Response and Drills
Emergency drills are conducted at Chevron facilities in
accordance with all applicable laws, regulations, and facility
policies. To ensure familiarity with the emergency procedures,
Chevron conducts drills as if an actual emergency exists.
Contractors are required to participate in all drills.
All drilling rigs will schedule, conduct, and record drills for
their personnel according to all applicable laws, regulations,
and policies.
32 | GOMBU and DWEP BU

5.0 HES Meetings
5.1 Onsite HES Meetings
Contractor shall conduct or actively
participate in onsite HES meetings as
made available, but at least daily.
These meetings can include:

• Interactively reviewing the Hazard
Analysis Standard, which includes
JSA/Job Safety Evaluation
Assessment (JSEAs), Think Incident
Free (TIF), etc., with team

• Discussing work to be completed and how to do the
work safely

• Analyzing lessons learned
• Sharing incidents and near misses
• Recognition
• Conducting a learning exercise
• Observing trends and discussing the corrective actions
tied to those trends

Note: For more information, please review the Hazard
Analysis section.

5.2 Pre-Job HES Meetings
Before a new job, at the beginning of each workday, or in the
event of a significant operational change, the person in
charge must hold a pre-job meeting to discuss job planning,
job assignments, the completion of a written Job Safety
Analysis, and any unique or unusual project hazards.

Contractor Handbook | 33

The person in charge must hold a pre-job meeting:

• Before a new job
• At the beginning of each work day

• In the event of a significant operational change
These meetings should contain, but not be limited to:

• Job planning
• Job assignments
• Completion of written JSA
• Any unique or unusual project hazards

34 | GOMBU and DWEP BU

6.0 Personal Protective Equipment
6.1 General
All personnel working for Chevron will wear appropriate
personal protective equipment (PPE) as determined by the
Hazard Analysis. It is the responsibility of each contract
company to provide PPE required by the specific task being
performed, the potential hazards to which the person will be
exposed, and the specifics of the job site. Contractors must
adhere to the minimum PPE requirements recommended on
the Material Safety Data Sheets (MSDS) for material they
are handling.

6.2 Fee for Arriving Without Appropriate PPE
If, upon arrival at a Chevron facility, a contractor does not
have the appropriate PPE for the job requested, Chevron
may either, at its discretion:

• Send the contractor back to retrieve the appropriate
equipment at the contractor’s expense.

• Provide replacement PPE for a fee of $100 per item.
Chevron will deduct this charge from the invoice for the
completed work.

6.3 Head Protection
• Contractors must wear a
hard hat when working in
field operations.

• Contractors must

V-Guard

Shock-Guard

maintain and replace the
hat’s suspension system,
as needed.

• No one is to alter (drill, rivet, or paint to change the
design) hard hats in any way.

Contractor Handbook | 35

• Hard hats must be made of nonmetallic material and
must comply with ANSI standard Z89.1 (or any
successor standard).

• Contractors must wear their hard hats squarely on their
head and not cocked to one side or turned in a reverse
position.

• Welding hard hats must be provided during welding








operations where overhead hazards are present. The
only exception to this guideline is when the welding
hard hat poses a hazard to welders due to body positioning
while performing their work. This exception to the policy,
along with explanation, must be documented on the Hot
Work Permit and noted on the JSA with all potential
hazards mitigated.

6.4 Eye Protection
Safety eyewear, clear (for night
operations) or tinted, is mandatory
for all personnel in field operations
(including visitors) and must be worn
outside of quarters and office
buildings:

• All safety eyewear (prescription and
nonprescription) must have side
shields or wraparound protection that meets ANSI
standard Z87.1.

• Safety eyewear will meet ANSI standard Z87.1. (The
notation Z87 should be on the frames or temples of
the safety eyewear.) This includes prescription eyewear
used as the only source of eye protection.

• Personnel should always shield their eyes from the arc’s
rays, including reflected rays from another surface, such
as the water. In addition, personnel must wear goggles
when helping or working near welders.

36 | GOMBU and DWEP BU

• Safety eyewear other than safety glasses may be required
for certain tasks, according to the following chart;
choose the most appropriate shade number from the
list for the particular activity.

• Inform the contractor’s supervisor when you are wearing
contact lenses.

• Do not wear contact lenses in areas where there is
potential exposure to a welding arc.

42 | GOMBU and DWEP BU

• Wear soft or gas-permeable lenses.
• Have a spare pair of contact lenses or prescription glasses
readily available to you.

6.6 Foot Protection
Safety footwear is mandatory in field
operations. Open-toed shoes, such as
sandals, slippers, Crocs®, and flipflops are unsuitable footwear when
on the work site or using Chevron
helicopters and crew boats.

• Visitors and employees not actually
involved in daily field operations,
such as helicopter pilots and Office Assistants (OAs), are
not required to wear safety footwear.

• Types of safety footwear allowed:
–  Lace-up, slip-on, or side-zipper leather shoes or boots
with steel toe
–  Western-style boots (provided the heel is not
excessively high) with steel toe

6.7 Hand Protection
Appropriate gloves must be worn
when the contractor’s hands are
exposed to hazards, such as cuts,
punctures, or abrasions (cloth, cutresistant, leather, or leather-palmed
gloves), when handling chemicals or
hazardous materials where absorption
is a concern (rubber gloves), and when
performing electrical work (certified
gloves for electrical work).

• Welding-Specific: Flameproof gauntlet gloves must be used
during all arc welding, gas welding, or gas cutting
operations, except when engaged in light work, such as
test-fitting pieces.

• Rigging-Specific: Gloves must be worn when performing
rigging duties.

• Galley/Cooking: All galley personnel who use knives during
food preparation are required to wear cut-resistant
gloves. The contractor will provide procedures for
cleaning and disinfecting these gloves.
–  Only countertop electric knife sharpeners will be
permitted for use in galleys and kitchens under
Chevron’s operational control.

• Divers are required to wear KEVLAR® gloves.
• Personnel using fixed or locking blade knives must wear
KEVLAR or leather gloves.
–  If a knife is the appropriate tool for the job, the
employee’s company is expected to provide the fixed or
locking blade knife and maintain it for that specific task.
A JSA must be completed before its use.

44 | GOMBU and DWEP BU

• Company and contract personnel are not allowed to






carry pocketknives with them at offshore locations. In
lieu of a pocketknife, an alternative cutting device must
be used and provided by the contractor (e.g., wire cutters
are an appropriate alternative cutting device for cutting
ty-wraps).

Anti-vibration
gloves

• Protection for highly specialized
tasks such as operating chainsaws,
grinders, nail guns, sanders, and any
machinery that produces high levels
of vibrations or where the individual
is exposed to excess vibration
• These gloves provide extra padding
to help prevent hand-arm vibration
syndrome (HAVS) that often occurs
from repeated exposure to vibration.

Cut-resistant
gloves

• Cut-resistant gloves are used when
workers are at risk to be sliced or cut
by equipment or the products they
are handling.

Contractor Handbook | 45

Electrical hazard
gloves

• Electrician gloves are used to protect
against electrical shock that could
result from an accidental contact
with energized electrical equipment.
• Consult your Electrical Safe Work
Practice advisor for more
information.
Reference Standard:
Rubber insulating gloves (ANSI
Standard J6.6-1967) should be used at
all times when working on general
electric equipment, elevators, branch
circuits and switches, emergency
power systems, and solar photovoltaic
systems, etc.

High-visibility
gloves

Are available in safety orange or lime
colors and come in day or nighttime
versions. Nighttime versions have
retro-reflective patches or elements to
reflect light beams (used by flaggers
or for communicating hand signals).

Kong

These are best used when handling
pipe and larger items where less
dexterity is needed (i.e., drilling
operations).
They are well designed and protect the
hand from:
• Hairline fractures
• Bruising blows
• Pinched fingers

Leather gloves

For protection from rough objects,
sparks and heat, and for cushioning
from blows in heavy-duty work. All
kinds of leather provide comfort,
durability, dexterity, mild heat
resistance, and abrasion protection.
These advantages make leather a
traditional favorite for industrial
workers.

Leather-palmed
gloves

Provide maximum protection against
abrasive and puncture hazards of the
palm area only. In most cases, other
areas of the glove are thin for more
dexterity.

Contractor Handbook | 47

Type of Hand
Protection

Possible Uses for This Type of
Hand Protection

(Photos are NOT

Mechanics’ style
gloves

These gloves are designed to be thin,
which allows for high dexterity, and
are very durable. This is a generic
catch-all name for an all-purpose
glove; there is a variety of versions
and different looks.
Note: Not liquid-proof.

Welding gloves

Made of leather with heat-resistant
panels. A special feature of effective
welding gloves is fully welted seams,
some sewn with KEVLAR fibers, which
are five times stronger than steel and
are flame- and heat-resistant. These
fibers protect the seams from
degeneration due to exposure to
abrasion, heat, sparks, or flames.

Note: Make sure you ask the right questions when

selecting a glove for a particular application.

Using the right glove for the task is worth the

investment compared to potential hand injuries.

6.7.2 Examples of Chemical Hand Protection
The material on the following list is only intended to
provide an overview of the chemical protective
glove categories.
Remember, coated gloves (i.e., chemical- or liquid-proof/
resistant gloves) are available in a few versions:
• Full-coverage for complete liquid-proof or chemical-
proof protection
• Palm, finger, and fingertip coverage for a breathable
glove
• Palm, fingertip, and knuckle coverage

Latex rubber

Is an inexpensive, waterproof glove
that works well but has limitations. It
will, however, blister and separate or
peel off in thin layers when in contact
with petroleum-based products. Best
used during first aid and food
preparation.

Nitrile rubber
(NBR)

Resists grease, oil, and other
petroleum-based products and is
water-resistant or waterproof (if fully
coated).

Contractor Handbook | 49

Type of Gloves
(Photos are NOT
for ordering

Possible Uses for This Type of
Hand Protection

Both PVC and
neoprene

Offer excellent chemical-resistant
properties. Polyvinyl chloride (PVC)
gloves frequently are used in the
petrochemical industry. Neoprene
gloves provide excellent chemical
resistance to a broad range of
hazardous chemicals, including acids,
alcohols, oils, and inks. Although
neoprene gloves can offer good grip,
they generally are thicker and heavier.

Polyurethane

Provides extra abrasion resistance and
extended wear. The coating does
provide waterproof protection but only
limited chemical resistance.

Polyvinyl
alcohol-coated
(PVA)

PVA gloves are nearly inert to strong
solvents, including aromatics,
aliphatics, and chlorinated solvents,
chemicals which quickly deteriorate,
natural rubber, neoprene, and PVC
gloves. PVA also offers good
resistance to snags, punctures,
abrasion, and cuts.
Caution: PVA coating is water-soluble.
Do not use in water or water-based
solutions.

50 | GOMBU and DWEP BU



Note: Make sure that on the glove the coating is

resistant to the types of chemicals that are

present. Select glove material based on the

manufacturer’s product literature to determine

the gloves’ effectiveness against specific work

place chemicals and conditions.






The U.S. Department of Energy Occupational
Safety and Health Technical Reference Manual
rates various gloves as protective against specific
chemicals and will help you select the most
appropriate gloves to protect your employees.






You can find the glove ratings on Table 4
Chemical Resistance Selection Chart for
Protective Gloves at http://www.osha.gov/
Publications/osha3151.html/.

6.8 Hearing Protection
Contractors will provide hearing
protection to their personnel and
ensure they are worn whenever those
employees work in areas requiring
hearing protection, such as:

• In posted areas and on helicopters
• In high-noise areas

6.9 Protective Clothing
This policy applies to ALL company and contract personnel
(including mechanics, electricians, operators, facility
representatives, construction representatives, drill
representatives, drilling contractors, etc.) who work on,
in, or around production areas/equipment or drilling
equipment.

Contractor Handbook | 51

Tour groups/visitors (for other than crew change purposes)
are required to wear long sleeves. Exceptions to this policy
for visitors will be at the discretion of the onsite person
in charge.
This policy DOES NOT apply to:

• Personnel who work in the field office or bunkhouse
(including OAs and catering personnel)

• Personnel passing through production areas in the
process of crew change (including boat and
vessel crews)
Contractors must observe the following clothing standards
at offshore work locations while working around production
equipment or outside quarters:

• All-cotton, long-sleeved, button-up shirts and long pants.
Overalls, coveralls with zippers, and jeans are acceptable,
as long as they are all cotton.

• Synthetic garments, such as polyester, nylon, or rayon,
may not be worn.

• Clothing shall be orderly – no holes, tears, frayed, or loose
material – and fit appropriately, with sleeves rolled down
and shirttails tucked into trousers.

• Rings, necklaces, and other loose jewelry, including
exposed body piercings are prohibited when working in
areas where they could catch on moving objects or sharp
protrusions or come in contact with electrical circuits.
–  Watches may be acceptable if protected by the

employee’s long sleeves. However, they must meet
Chevron’s GOM Daily Non-Welding Hot Work Permit
requirements (e.g., powered by no more than two
button-type batteries).

• Suitable protective clothing (specified on current MSDS/
JSA) will be worn when handling chemicals or hazardous
substances.

52 | GOMBU and DWEP BU

• Clothing and shoes saturated with petroleum products or
chemicals will be removed immediately to prevent skin
irritation and possible ignition.

• Rain gear is acceptable as an outer layer in appropriate
weather conditions.

6.9.1 Fire-Resistant Clothing









Contractors will provide Fire-Resistant Clothing (FRC),
and PPE to their personnel and ensure they are worn
based upon the incident energy exposure associated with
the specific task. At a minimum, FRC is required for all
contractor electricians and automation specialists working
on Chevron facilities. FRC selected by a contractor must
provide for electrical arc protection. INDURA® or
EXCEL-FR™ brands are acceptable.

FRC may be required for non-electrical contractors who
perform certain duties with a high risk of flash fires.
For high-voltage applications, additional requirements are
listed in the Chevron Electrical Safe Work Practice Manual.
Consult a Chevron representative for more details.

6.10 Respiratory Protection
Contractor companies whose
personnel perform work requiring
respiratory protection are required to
have a documented respiratory
protection program in place. The
contractor company must ensure that
their personnel are properly trained,
medically cleared, and fit-tested, and
that the program is properly implemented.

Contractor Handbook | 53

6.11 Personal Flotation Devices
USCG-approved Type I life preservers
or Type V or Type III/V work vests
are required at all times over
water locations.
USCG Type I life preservers are
provided by Chevron for emergency
situations and during emergency
drills. Type I life preservers are
typically stored in orange boxes at
facility muster sites and near primary
means of egress.
It is the responsibility of the
contractor company to provide their
employees with U.S. Coast Guardapproved Type V or Type III/V work
vests as needed.

Type V work vest

Type III/V work vest

All personal flotation devices (PFDs)
must be securely fastened, fit snugly, and be in good
condition. PFDs must be worn during the following activities:

• When transferring to or from any watercraft (by swing
rope, personnel basket, or gangway)

• Outside the cabin or wheelhouse of a watercraft
(including barges)

• When riding in an open or semi-open watercraft
• When entering the water to perform work (diving
operations excluded)

• Any other time deemed necessary by the vessel captain
or PIC

• Accessing areas below the sump deck

54 | GOMBU and DWEP BU

• When working on the boat landing or Plus 10 level when
not surrounded by guardrails
Only Federal Aviation Administration (FAA)-approved
inflatable PFDs are provided in, and shall be worn on, all
helicopters.

6.12 PPE During After-Hours
All personnel working for Chevron will wear appropriate PPE
during after-hours if outside the galley and living quarters.

Contractor Handbook | 55

7.0 Transportation
7.1 Marine Transportation
These guidelines apply to contractor personnel and
equipment transported by a vessel under charter to
Chevron.

• Safe operation of a vessel chartered to Chevron is the
exclusive duty of the captain and owner of the vessel.

• Only properly licensed captains employed by the vessel





owner will operate and navigate vessels under charter to
Chevron. Only qualified personnel who hold the
appropriate licenses, if required, will operate all other
vessels used in Chevron’s field operations.

• The captain of the vessel will
refuse to allow persons not
adhering to the PFD rules to board
a vessel.

• The captain of the vessel will











ensure that the cargo is
properly positioned and secured on
the vessel before leaving our
facilities. Fastening equipment for securing
cargo on marine vessels will be furnished by the marine
company. The only acceptable chain binders are the
cam-lock safety binders or the ratchet-type binders.
Single lever, boomer-type binders are prohibited. The
captain of the vessel has final authority to refuse to
transport any cargo not properly secured.

• The captain of the vessel has the authority to refuse
passage to anyone considered an unsafe passenger.

• The captain of the vessel can refuse transportation of any
hazardous materials that have not been properly
identified, classified, named, packaged, marked, labeled,
and manifested.

56 | GOMBU and DWEP BU

• The captain of the vessel shall
request a JSA on all lifts performed
with lift team.

• The captain of the vessel may
require that seat belts be worn
where available.

• Materials, equipment, tools,





containers, and other items used in the Outer Continental
Shelf (OCS) that are of such shape or configuration that
they are likely to snag or damage fishing devices will be
handled and marked as follows:

–  All loose materials, small tools, and other small objects
will be kept in a suitable storage area or a marked
container when not in use.
–  All cable, chain, or wire segments will be recovered
after use and securely stored until suitable disposal is
accomplished.
–  Skid-mounted equipment, portable containers, spools,
reels, and drums will be marked with the owner’s name
before use or transport over offshore waters.
–  All markings must clearly identify the owner and must
be durable enough to resist the effects of the
environmental conditions to which they may be exposed.
–  Additionally, BOEMRE PINC G-251 stipulates that the
above markings cannot be made with chalk, grease
pencil or crayon, marking pens, non-waterproof decals,
or water- based paints.

• Selective unloading, also known as cherry picking, will







be avoided as part of our cargo planning. Selective
unloading or cherry picking is when riggers/deck crew
climb on top of lifts (i.e., cargo containers, boxes,
containers, etc.) or enter unsafe deck areas (where
confinement does not allow easy access to cargo

Contractor Handbook | 57

and the opportunity for safe evacuation of this area,
i.e., when cargo is secured closely to bulwarks not allowing
sufficient access by riggers/deck crew).
–  In the case of infield moves where the Decision Support
Center/shorebase is currently not involved in cargo
planning, the vessel captain and lift team leader will
incorporate into the Pre-Lift JSA a plan to avoid
selective unloading (cherry picking).
–  When there is a departure from the agreed sequence of
deck cargo offload (cherry picking) SWA must be
exercised and the Cargo Plan should be discussed,
revised, and agreed upon with the lift team (captain,
crane operator, and riggers), the PIC of the facility (or
delegate), and other persons involved in the operation.
–  A JSA which specifically addresses the hazards
associated with the revised Cargo Plan must be
completed and documented and a copy retained by the
vessel crew. The JSA cannot be a checklist and must
include an assessment of current weather, sea
conditions, cargo on board, and any other considerations
particular to the situation.
–  Organize cargo placement to maintain access/egress
routes. Personnel should avoid climbing on cargo or
walking on tubulars.
Note: Personnel transfers from boat to boat in open

waters are generally not recommended, unless

there is no other practical means of transfer.

When such transfers are necessary (e.g., at dive

spread vessels, construction barges, or lay

barges), they should be performed only after

other means of transfer have been evaluated

and excluded, the safety of the transfer is

deemed acceptable, and a thorough JSA has

been completed.

58 | GOMBU and DWEP BU

Boat-to-boat transfers in which neither boat is anchored,
moored, or using a dynamic positioning system will not take
place, unless there is an emergency that requires the
transfer to save lives. In such a case, all efforts must be
exhausted to ensure that the transfer does not expose
emergency personnel to greater danger.
Refer to the MSRE Personnel Transfer Procedures, which
can be found on the Gulf of Mexico Contractor Safety
website at http://upstream.chevron.com/contractorgom/
programs_policies/marine_safety.asp/.

7.2 Personnel Transfers
• Only qualified crane operators can perform unsupervised





personnel lifts. For Chevron- and contractor-owned cranes
on Chevron facilities, personnel designated as Class A
crane operators (Chevron or contractor) are considered
qualified.

• Any Chevron employee hiring a third-party crane operator
to perform personnel transfers must verify that the
person is a qualified crane operator and is experienced
with personnel lifts.

• Follow the recommendations outlined in API Spec 2C and
API RP 2D when using cranes to transfer personnel.

• Cranes will be classified as “personnel handling” and
identified with a sticker depicting a personnel basket.

• Hoists will be equipped with a personnel handling
certification tag. The hoist certifications are maintained in
the crane file. Personnel-certified hoists are maintained
according to manufacturer’s recommendations.

• Cranes classified as personnel handling will be equipped






with a boom hoist pawl to prevent unintentional lowering
of the boom. These cranes also have an emergency load
lowering kit available on the platform. For hydraulic boom
cylinders, the crane is equipped with a holding device,
such as an integrally mounted check valve.

Contractor Handbook | 59

• Hooks on headache balls or on blocks used to transfer
personnel will be a type that can be closed and locked
(API 2C, 6.5.3.3).
Note: When using a stinger to transfer personnel, hooks

for both the headache ball and block and stinger

must be a type that can be closed and locked.

• Personnel baskets used to transfer people to and from








rigs, platforms, and boats must be designed for and in a
condition suitable for the intended purpose (API RP 2D).
Each personnel basket must contain a stainless steel
certification tag provided by the manufacturer. The
certification tag should specify the description, pertinent
working load limits, size and length of the sling, supplier’s
name, and the proof test certification number and date.

• A tag line must be used on all personnel baskets. The tag






line should be attached to the bottom center of the
basket, 15 to 20 feet in length, and should be free of any
knots or splices. Riggers must not get beneath the basket
to retrieve the tag line. If necessary, hooks or other
devices should be used to retrieve tag lines.

• All personnel transported on a personnel basket must
wear a PFD and hard hat.

• For the Billy Pugh collapsible basket, personnel will stand
on the outer rim facing in toward the basket; luggage
must be positioned in the center of the basket, not
stacked, to avoid unexpected shifts.

• For the X-904, grab the outer ropes, step onto the
basket, and position your feet as indicated by painted
footprints on the basket floor.
Note: Do not attach the quick-release safety lanyard

until you step into the basket.

60 | GOMBU and DWEP BU

• For the X-904, attach the quick release safety lanyard clip
to the upper nylon strap of the PFD work vest between the
stitching, not onto the PFD fastener. The safety lanyard
serves as a fall restraint and should not be considered fall
protection. Pass your arms around the inner rigging ropes
and cross them for a secure grip. The deckhand or rigger
will signal the crane operator when the riders are properly
secured. Personnel baskets will carry no cargo other than
personal luggage or small tool bags/boxes.

• Personnel baskets should not be on a platform, unless the
platform crane is classified for personnel handling. The
crane load charts will include the capacity rating for
personnel lifts.

• Before using a personnel basket, the crane operator or
qualified rigger must ensure that the basket is in
serviceable condition and certified. At a minimum,
personnel should look for frayed or broken nylon ropes,
worn or kinked cables, and dry-rotted canvas mat in the
center (Refer to the Personnel Basket Inspection
Section 7.3.2).

7.3 Personnel Baskets
7.3.1 General Information
• Personnel baskets must be
equipped with a proper tag line.

• The tag line should be attached
to the bottom center of the
basket and should be free of
any knots or splices.

• Personnel baskets must be
equipped with a stabilizer.

• Personnel baskets may serve as a temporary flotation
device in emergencies.

• The number of passengers in a personnel basket shall
not exceed the manufacturer’s specifications.

Contractor Handbook | 61



• The vessel captain or crane operator may reduce this
limit depending on weather and sea conditions.

7.3.2 Inspection








In addition to cursory inspections that should be
conducted before each use, all load-bearing parts of
the personnel basket should be inspected by a
competent person in accordance with manufacturer’s
recommendations. If there is any excessive wear or
damage, the unit should be removed from service until it
can be repaired or replaced.

• Every six months, contractors must send a qualified
person who meets the relevant American Petroleum
Institute (API) specifications to conduct a thorough
inspection of the unit.
• Personnel basket slings will be inspected yearly in
accordance with Chevron’s sling policy (See Section
17.6).





Every two years, contractors are responsible for
refurbishing personnel baskets and replacing parts
as required. All load-bearing lines, hardware, covers,
and flotation items should be carefully inspected.

Note: For contractors using the X-904, the center post

should be evaluated for structural integrity during

this two-year inspection.



7.3.3 Safe Use







Contractors are responsible for training their employees
in proper personnel basket use to include general safety
issues and specific transfer procedures. Some general
personnel baskets safety guidelines that should be
addressed in training include:

• Never stand under a personnel basket. Riggers must
not get beneath the basket to retrieve the tag line. If

62 | GOMBU and DWEP BU

necessary, use hooks or other approved devices to
retrieve the personnel basket tag line.

• Place small, hand-carried items in the center of the
basket.

• Carry nothing in your hands, and do not wear gloves.
• Wear a properly fastened life preserver or work vest
(USCG-approved Type I device or Type V or Type III/V
work vest).

• Stand in the center of one of the openings in the
netting.

• Keep knees flexed, with one foot on the ring of the
basket and one foot on the deck.

• Pass arms through the netting and cross them for a
more secure grip.

• Be ready for the unexpected.
• Balance the load by spacing passengers evenly on
the basket.

• Should the basket contact the boat at the top of a
swell, Do not step off, as you could fall as the boat
drops away from you.

• Should the basket contact the boat as it is rising on a
swell, be prepared for a sudden jar.

• The basket should contact the boat at the bottom of a
swell. As it does, flex your knees with one foot on the
ring of the basket and be ready to place the other on
the deck. As slack appears on the basket, step off
quickly and get clear of it.

• Do not lean inward on landing. You could lose your
balance and fall into the basket or be struck by the
headache ball.

• Heavy material will be transferred in a cargo box or
cargo basket.

Contractor Handbook | 63

• Hard hat/strap must be worn during transportation.
Note: Anyone involved in the transfer should use

Stop-Work Authority any time they feel conditions

are unsafe.

7.4 Swing Rope Guidelines and Procedures
On boats with deckhands, a deckhand wearing a PFD must
be on deck to assist passengers any time a personnel
transfer is made. Factors used to determine when transfers
could be safely made include the direction of the sea, wind,
and tide, and the physical abilities of the personnel. Anyone
involved in the transfer should use Stop-Work Authority any
time they feel conditions are unsafe for transfer.
Contractors are responsible for training their employees in
proper swing rope use to include general safety issues and
specific transfer procedures. Some general swing rope
safety guidelines that should be addressed in training
include:

• When transferring luggage, materials, and equipment
from boat to dock, use a materials basket with the crane.
If this is not possible, pass items to the deckhand before
transferring to the boat, then have the deckhand pass
the material to you when you are on the dock.

• Do not wear gloves.
• When transferring from the structure to a boat, time your
swing so that your feet land on the boat deck as it
completes its rise. Before you swing, watch the boat as it
rises with the wave, timing your action.

• When transferring from a boat to a structure, time your
swing so that you leave the boat just as it dips down from
the highest point in the wave.
–  Grab the knotted rope high enough to clear the
structure’s catwalk when the boat is on top of a swell,

64 | GOMBU and DWEP BU

in most cases, the appropriate place to grab the rope is
just above the middle knot or at eye level.
–  Release the rope for the next person after landing.
–  Be alert and help the next person make a safe landing.

7.5 Helicopter Safety
When working around helicopters, it is necessary to adhere
to the specified safety guidelines. Personnel should always
approach the aircraft with the rotors spinning at a
45-degree angle and only after making eye contact with
the pilot. The rotor spins at such high speeds that it is not
visible. The rotor is one of the most severe hazards to
personnel working around helicopters, and its danger
cannot be overemphasized. These guidelines apply to
helicopter safety.

DANGER

DANGER

Warnings: Use extreme caution when approaching an
S-76 with its rotors spinning as this aircraft’s
main rotor height is lower than other aircraft
in the fleet.




Never walk around the tail rotor, cross
under the tail boom, or go beyond the
baggage compartment door of the helicopter.

General helicopter safety procedures include:

• Advise the aviation dispatcher before transporting any
hazardous materials, such as explosives, flammables,
compressed gases, and radioactive substances. All
hazardous materials shipments must conform to

Contractor Handbook | 65

Department of Transportation (DOT) regulations (49 CFR
Parts 170-179) regarding identification, hazard
classification, proper shipping name, packaging, marking,
labeling, and manifesting.

• Use the scales provided to weigh both your person and
your luggage accurately for every flight.

• Remove and stow any unsecured headgear including
hard hats before approaching a helicopter.

• Notify the flight dispatcher and pilot if you are a first-
time passenger. You must view Chevron’s Flight Safety
and Aircraft Orientation film before boarding the
aircraft. You will also receive extra assistance and
guidance during boarding and unloading the aircraft.

• Inform the pilot if you are unfamiliar with your
destination, so that you may be notified when you
arrive at your destination. This action reduces confusion,
because helipads are marked by their geographical
location, which may not be their commonly called name.

• Smoking, chewing tobacco, and use of snuff are
prohibited onboard aircraft.

• Passengers must comply with the following guidelines
for dress:
–  Long pants are required – no shorts.
–  Shirts must have collars – no tank tops.
–  No petroleum- or chemical-saturated clothing or shoes
are permitted.
–  Proper shoes are required – no thongs, sandals,
slippers, Crocs, or flip-flops.

• Wear hearing protection – either earplugs or earmuffs.







Earplugs are provided on each aircraft, or you may
provide your own. Please do not discard used earplugs
inside aircraft, on the flight decks, or on airport ramps.
This can cause a safety hazard, because helicopter rotor
wash can pick up such debris and ingest it into the
engines.

66 | GOMBU and DWEP BU

• Securely fasten and wear an inflatable personal flotation
device (PFD) aboard the aircraft as provided by the pilot.
Warning: Never inflate the aviation life jacket inside
the aircraft.

7.6 Aviation Emergency Medical Procedures
The transportation priority for first-aid incidents is the next
available flight. Medical emergencies are those situations
requiring immediate evacuation.
For first-aid incidents, personnel may use ground
transportation once the aircraft reaches the shorebase.
Contractor company personnel should meet their injured
employee at the base and arrange transportation from that
point to a medical facility. Evacuation offshore should be
coordinated through Chevron.
When an emergency flight is requested, it is assumed that
the incident exceeds the first-aid category. Medical
emergencies will be flown to the nearest designated
hospital, unless special situations, such as weather or the
nature of the emergency, dictate otherwise. The medical
provider in charge of any injured person will have the final
say as to which medical facility the injured is transported.
During inclement weather, personnel may have to be
transported to the shorebase by boat. If severe weather
conditions prevent helicopter evacuation, the contractor’s
company must arrange for ambulance and medical
personnel to be at the boat dock.

7.7 Hazardous Materials Transportation
Department of Transportation Hazardous Materials
Regulations (49 CFR Parts 170-179) apply to Chevron
operations whenever hazardous materials are transported
by air, water, or highway. Any person who is responsible for
classifying, packaging, marking, labeling, placarding,

Contractor Handbook | 67

handling, or preparing shipping papers for regulated
hazardous materials must have the required training to
perform those job duties. Chevron is obligated to report
any violations of these regulations.

• Advise the boat captain








or aviation dispatcher
before transporting any
hazardous materials,
such as explosives,
flammables, compressed
gases, or radioactive
substances.

OXYGEN

FUEL OIL

• Ensure that all hazardous materials shipments conform to
DOT regulations regarding identification, hazard
classification, proper shipping name, packaging, marking,
labeling, and manifesting.

• Document hazardous waste on a Hazardous Waste
Manifest, not a Straight Bill of Lading.

• Identify any container delivered to a shorebase or







heliport that contains dry ice (frozen carbon dioxide) on
the manifest or other shipping papers. The amount of dry
ice in the container should also be included on the
manifest or shipping paper. (Dry ice is not a DOT-regulated
hazardous material when shipped by highway, but it is
regulated when shipped by air or water.)

7.8 Foreign-Flagged Vessels
Foreign-flagged vessels require special consideration for use
in the U. S. Gulf of Mexico due to specific legal, both
statutory and regulatory, requirements. Consult a Chevron
regulatory specialist before using a foreign-flagged vessel.

• If arriving directly from a location outside the United






States, all vessels (mobile offshore drilling units [MODUs],
anchor-handling vessels, survey vessels, installation
vessels, construction barges, tank barges, etc.) hired by
Chevron or a Chevron contractor that are registered in a
country other than the U.S. (foreign-flagged) must comply

68 | GOMBU and DWEP BU








with the arrival and entry requirements of the U.S.
Customs and Border Protection (CBP) before working for
Chevron on the U.S. Outer Continental Shelf (OCS) within
or beyond the territorial sea. Before departing from a
U.S. port or place, foreign-flagged vessels must satisfy
any clearance requirements imposed by CBP.

• Under no circumstances is a foreign-flagged vessel





permitted to load at a U.S. port or place (a coastwise
point) any cargo or merchandise intended to be
transported to and offloaded at a different coastwise
point, including an OCS facility.

• On a case-by-case basis as permitted by CBP, a foreign-






flagged vessel may transfer materials from a U.S. port or
place to an OCS location where the vessel itself will
perform installation services using the materials. Contact
a DWEP regulatory specialist for guidance in obtaining
proper CBP permission.

• A U.S.-flagged, coastwise-endorsed vessel may transport











cargo, merchandise, or other equipment from a U.S. port
or place to a different coastwise point, including an OCS
location, or to a foreign-flagged vessel located at the
lease block where the materials will be used or installed,
provided the foreign-flagged vessel does not participate in
the transportation. A U.S.-flagged, registry-endorsed
vessel may deliver materials to unattached MODUs or
assist in anchor-handling. Contact a DWEP regulatory
specialist for guidance on specific interactions between
U.S.-flagged and foreign-flagged vessels.

• Chevron project teams should contact a Chevron BU
regulatory specialist for guidance prior to contracting a
foreign-flagged vessel to work on the OCS.

• Foreign-flagged MODUs and construction vessels may






load at U.S. ports the equipment necessary for executing
their typical work functions at OCS locations. Such
equipment is considered to be ship’s gear or vessel
equipment and is not considered to be merchandise
transported between ports or places in the United States.
Contractor Handbook | 69






However, it may be advisable to obtain advance CBP
verification that the anticipated activities are permitted.
Contact a DWEP regulatory specialist to coordinate that
effort.

• A foreign-flagged vessel is not permitted to conduct
salvage operations in the territorial waters of the U.S.
Gulf of Mexico.

• Chevron project teams should contact a Chevron BU
regulatory specialist for guidance before contracting a
foreign-flagged vessel to work on the OCS.

7.9 Marine Safety, Reliability, and Efficiency

70 | GOMBU and DWEP BU

8.0 Offshore (Water) Safety
8.1 Personnel Entry Into Water
Entry into the water shall be permitted only when:

• A diver is to perform specified work, pending approval of
the Permit to Work (PTW) and JSA.

• An “abandon platform” order is given.
If rescuing a person in the water when there are no other
reasonable rescue alternatives, personnel performing the
rescue should don a PFD and attach a lifeline. Other persons
should be available to secure the lifeline and retrieve the
person in the water.

8.2 Helicopter Underwater Egress Training
and Water Survival Training
All personnel who work a rotational position in the offshore
Gulf of Mexico and all personnel who will, or have the
potential to, travel there more than 12 days per calendar
year are required to be trained in Helicopter Underwater
Egress Training and Water Survival Training (HUET/WST).
All such personnel are required to have refresher training at
least every three years. Specific details regarding training
content and trainer competence are available on the
Chevron Contractor External website at https://upstream.
chevron.com/contractorgom/.
Note: DWEP ONLY




All personnel must have HUET regardless of how
many trips offshore. Refresher training is required
every three years.

Contractor Handbook | 71

9.0 Environmental Stewardship
Chevron is committed to working to prevent pollution
and waste, striving continually to improve environmental
performance and limit environmental impact from
our operations.

9.1 Waste Management
For waste generated by the contractor (e.g., paint waste
from painting the contractor’s equipment or used motor oil
resulting from an oil change in the contractor’s equipment),
it is the contractor’s responsibility to handle, document, and
dispose of that waste in accordance with all applicable
government regulations.
Waste generated on Chevron’s behalf must be handled
according to Chevron’s waste procedures.
Prohibited Practices
The following waste management practices are prohibited:

• Burning of liquid or solid materials in pits, piles, drums, or
other open containers. This also applies to the use of burn
baskets on offshore platforms operated by Chevron.

• Disposal of liquid waste in landfills.
• Disposal of oily wastes (sand, scale, rags, filters, PPE, etc.)
in containers not dedicated to such material.

• Disposal of Chevron waste in disposal facilities not
audited and approved by Chevron. Consult with your
Chevron contact for information on approved disposal
facilities.

72 | GOMBU and DWEP BU

Prohibited Materials
The procurement of new materials or any equipment (new
or used) containing materials listed below is prohibited1:

• Ozone-Depleting Substances (ODS), as defined by the
Montreal Protocol. These are the specific chemicals that
have been defined by the Montreal Protocol as having
adverse effects on the stratospheric ozone layer. They
include chlorofluorocarbons (CFC 11, 12, 13, 111, 112, 113,
114, 115, 211, 212, 214, 215, 216, and 217); Halon 1211, 1301,
and 2402; hydrobromofluorocarbons (HBFCs); carbon
tetrachloride, 1, 1, 1-trichloroethane and methyl bromide.
Existing equipment containing ODS may be operated
and maintained until the end of its normal life cycle.

• All forms of asbestos-containing products, defined as
any material containing more than 1% asbestos. While
not an exhaustive list, the following products may fall
into this category: pipe-covering, insulating cement,
insulating block, asbestos cloth, gaskets, packing
materials, thermal seals, refractory and boiler insulation
materials, transite board, asbestos cement pipe,
fireproofing spray, joint compound, vinyl floor tile,
ceiling tile, mastics, adhesives, coatings, acoustical
textures, duct insulation for heating, ventilation, and air
conditioning (HVAC) systems, roofing products,
insulated electrical wire and panels, and brake and
clutch assemblies.

• PCBs. Polychlorinated biphenyls are employed in
industry as heat exchange fluids, in electric
transformers and capacitors, and as additives in
1 Potentially less harmful alternative materials should be substituted









for prohibited materials wherever possible. In particular, as of the
applicable compliance date (Appendix B), existing air conditioning
and refrigeration equipment containing ODS can be maintained
(recharged) only with recycled or reclaimed ODS, or with
acceptable alternative refrigerants. Existing inventories and
equipment can be used or managed in place as long as the
prohibited materials do not pose a health or environmental
concern, and removal is not required by local regulations.

Contractor Handbook | 73

paint, carbonless copy paper, sealants, and plastics. PCBcontaminated materials are defined as materials exceeding
50 mg/kg of PCB oil.

• Lead-based paint.
• Leaded-thread compound (pipe dope).
Waste Minimization
Chevron operates under the following waste management
hierarchy guidelines:

• Reduce the amount of waste at the source by ordering
only the amount of chemical or other materials needed to
do a job.

• Return unused portions of the chemicals or materials to
the vendor.

• Reuse a material, if possible.
• Recycle or regenerate wastes for continued use.
• Dispose of waste at a facility audited and approved
by Chevron.
When dealing with waste, it is important to identify the
material and use it as intended or to find an alternate user.
If the material cannot be used, keep it segregated and
obtain guidance from a Chevron representative on how to
identify and dispose of it. Waste transported from offshore
or from shorebase locations must be accompanied with the
proper paperwork and have the correct markings.
Guidance for handling, storing, documenting, and
disposing of waste can be found in the GOMBU Waste
Management Plan.

9.2 Waste Categories
Wastes generated from GOMBU’s exploration and
production activities include those defined as hazardous
waste, Exploration and Production (E&P) waste, solid waste,
and other regulated waste, whether recycled or disposed.

74 | GOMBU and DWEP BU



9.2.1 Hazardous Waste

Waste will be classified as hazardous if any of the
following conditions exist:






The waste is listed as a hazardous waste in 40 CFR
261 or in applicable state hazardous waste regulations.
The lists are generally referred to with respect to
Environmental Protection Agency’s (EPA’s) assigned
waste code: F-List, K-List, P-List, or U-List.






The results of laboratory analysis indicate that the
waste meets one of the following criteria specified in
the regulations to be classified as characteristically
hazardous:

–  Ignitability – D001: flashpoint less than 140° F
–  Corrosiveness – D002: pH < 2 or pH > 12.5

–  Reactivity – D003: is explosive or releases harmful
quantities of cyanide or sulfide gas

–  Toxicity – D004 through D043: leaches certain
metals, organics, chlorinated organics, pesticides, or
herbicides
• The company requires that the waste be treated as a
hazardous waste, even though it is not a regulatory
requirement.

9.2.2 E&P Waste









The Louisiana Department of Natural Resources (LDNR)
has very specific criteria to determine when a waste is
considered E&P waste, and thus regulated by Statewide
Order 29-B. It is E&P waste if waste in question came
from downhole, or is uniquely associated with waste that
came from downhole, such as wash water from vessels
that contained E&P waste and sorbent materials used in
the cleanup of an E&P waste spill.






Some waste meeting the definition of E&P waste, such as
oiled absorbent booms and pads, is tested and managed
as commercial waste, because the LDNR-licensed facilities
(29-B facilities) cannot properly handle it.
Contractor Handbook | 75

9.2.3 Solid Waste
Examples of solid wastes are:
• Commercial solid waste
• Construction/demolition debris
• Industrial solid waste
• Residential solid waste
• Garbage
• Trash

9.2.4 Other Regulated Waste





Some types of waste must be handled and disposed of in
accordance with other regulations in addition to the
Resource Conservation and Recovery Act (RCRA).
Examples of waste included in this category are:

• Asbestos – regulated in Louisiana by the Louisiana
Department of Environmental Quality (LDEQ) Air
Quality Division






NORM – regulated in Louisiana by the Louisiana DEQ
Radiation Protection Division and Louisiana DNR; in
Mississippi by the Mississippi Department of Health and
the Mississippi Oil and Gas Board; and on the OCS by
the BOEMRE

• PCB waste – regulated under the federal Toxic
Substances Control Act (TSCA)

9.3 Pollution Prevention
Chevron expects pollution prevention to be a responsibility
of contractor companies and their subcontractors when
working for Chevron. Furthermore, Chevron expects the
contractor company and its subcontractors to comply with
all local, state, and federal laws, rules, and regulations
relative to and concerned with spill prevention and
pollution control.

76 | GOMBU and DWEP BU

• If Chevron’s contractors and/or their subcontractors






encounter or foresee a potential pollution hazard or spill
event occurring during an operation, immediate steps
must be taken to eliminate the hazard and/or minimize
the effect. The responsible Chevron representatives must
be notified of the event.

• Chevron expects contractor companies and their
subcontractors to maintain their immediate work areas
free of all harmful spillage, discharge, or other pollutants.

• Chevron will furnish the status and other necessary





information on wells, systems, or pressure vessels for the
contractor’s and its subcontractor’s activities, where
appropriate, at the beginning of or during a particular
operation.

• If work involves pressure, the wells or system may be bled





down before initiating service work. Flowlines may be
displaced with water where practicable to prevent
pollution. Performance of these items will be coordinated
with the responsible Chevron representative.

• Drip pans or equivalent containment devices will be
positioned to catch oil, which may have to be drained or
allowed to run out of lines or equipment to allow work to
progress. Additionally, appropriate plugs must be in place.

• In the performance of all work, contractor companies and






their subcontractors must perform the same in
accordance with the best technical procedures and
professional manner, and they will obey and comply with
all local, state, federal laws, rules, and regulations, as well
as those promulgated by agencies thereof.

9.4 National Pollutant Discharge
Elimination System
The National Pollutant Discharge Elimination System
(NPDES) Process is designed to comply with the monitoring
and documentation requirements of the NPDES permits

Contractor Handbook | 77

that apply to the operations in the GOM. The process also
seeks to prevent noncompliance through process monitoring
and continual improvement.
Only those discharges specifically authorized by the
appropriate permits may be discharged into the Gulf of
Mexico. Any substance not specifically authorized by permit
cannot be discharged. Before discharging anything from or
into a drainage system on an offshore facility, the contractor
must verify through a Chevron representative whether a
discharge is allowed, and, if so, what permit terms and
conditions govern that discharge.
Some examples of discharges covered by this section
include, but are not limited to:

• Deck drainage
• Domestic waste
• Drill cuttings
• Drilling fluids
• Hydrostatic test water
• Produced sand
• Produced water
• Sanitary waste
• Uncontaminated ballast water
• Uncontaminated bilge water
• Uncontaminated seawater or freshwater
• Workover or completion fluids
Chevron representatives (including contractors) need to be
trained in the specific NPDES requirements for the area of
operations. This training must be specific for their job scope.
Specific training requirements can be found in the Chevron
GOM OE Manual. The monitoring and reporting
requirements for specific permits can be found in the
Discharge Permits Manual.

78 | GOMBU and DWEP BU

10.0 Occupational Health and
Industrial Hygiene
10.1 Fit for Duty
Contractors are responsible for ensuring that employees
who are sent to work under Chevron’s operational control
are physically capable of performing their job function. This
includes a pre-employment physical for all contractor
personnel.
To meet this responsibility, the contractor must train their
employees to:

• Implement and enforce their safety program, and
ensure that all employees are properly trained for their
assigned tasks.

• Ensure that personnel assigned to work at Chevron
locations are fit for duty and physically capable of
performing all aspects of their jobs.

• Follow safe work practices and procedures.
• Provide their employees with proper personal protective
equipment in good working condition.

• Notify a supervisor when the employee is taking
medication, both prescription and nonprescription, that
could impair his/her ability to work safely.

• Ensure that the contractor’s employees know and comply
with Chevron’s drug and alcohol requirements.

• Conduct appropriate industrial hygiene monitoring and, if
requested, provide copies of the results to Chevron.

10.2 Hazard Communication (HAZCOM)/
MSDS Program



If a contractor brings a chemical to a Chevron facility, the
contractor is required to have the chemical labeled properly,
to travel with a valid and current MSDS, and to report the
chemical to the person in charge upon arrival.
Contractor Handbook | 79

The person in charge of the facility
will ensure that contractors are
informed of the hazardous chemicals
their employees may be exposed to
while working on Chevron property.
The person in charge is responsible
for:

• Communicating the identity of any
hazardous chemicals to contract employees or visitors
who may be immediately exposed while working at the
location.

• Informing contractors of the labeling system in use, the
protective measures to be taken, the safe handling
procedures to be used, and the location and availability of
MSDS while working on Chevron locations.

• Obtaining the chemical identities and MSDS on hazardous
chemicals the contractor may bring onto Chevron
locations and informing the employees at the location of
the associated hazards of each chemical.

10.3 General Industrial Hygiene Principles
Contractors are responsible for identifying health hazards
that may be present in their scope of work, ensuring that
appropriate programs and monitoring are in place to protect
their employees.
Industrial hygiene is defined as “that science and art
devoted to the anticipation, recognition, evaluation, and
control of those environmental factors or stresses arising in
or from the workplace, which may cause sickness, impaired
health and well-being, or significant discomfort among
workers or among the citizens of the community.”
Chevron’s industrial hygiene objectives are to:

• Protect the health of all personnel working under
operational control.

80 | GOMBU Shelf and DWPBU Deepwater

• Provide a framework for recognizing and managing
health hazards.

• Comply with regulatory requirements.
Some key industrial hygiene issues are described in the
following sections.

10.3.1 Naturally Occurring Radioactive

Material
Naturally Occurring Radioactive Material (NORM) is
low-level radiation, which results from concentration
of radioactive minerals during extraction of oil and gas
from the earth. NORM can be found in piping, tubing,
sludge pits, brine, sand filters, salt-water disposal injection
wells, and other equipment. When scale or a thin film is
present, or if NORM contamination is suspected, the
contractor should contact a Chevron representative to
confirm whether NORM exists in the area and to receive
site-specific NORM procedures.











Contractors and employees may be exposed to possible
external or internal NORM. Limiting exposure time can
control external exposure. The internal hazards occur
when airborne radioactive materials are inhaled,
ingested, or enter the skin through open wounds. These
hazards can be minimized by properly wearing an
approved respirator, by practicing good personal
hygiene, and by protecting wounds and cuts. Wetting
the loose material on clothing with water can also
prevent inhalation.

• Coordinate storage of NORM-contaminated materials
through the shorebases.

• Contact the onsite Chevron representative to
coordinate disposal with the HES coordinator on
location or the shorebase before shipping NORM for
disposal.
• Only trained, non-SSE personnel may handle piping,
equipment, junk iron, or solids containing NORM.

Contractor Handbook | 81

• When working at facilities identified to produce NORM
contamination, rags, wipes, PPE, and other equipment
may be contaminated with NORM. Scale, sand, and
sludge from piping and process equipment may also
contain NORM. Segregate and contain these materials
separate from other wastes; never mix these materials
with ordinary trash. Scan these materials with a NORM
meter, and flag them if they contain NORM.


10.3.2 Asbestos








Asbestos is generally used as pipe and vessel insulation, in
brake pads, and on structural materials, such as transit
panels, floor tiles, and roofing felts. It is often difficult to
differentiate between asbestos and non-asbestos without
laboratory equipment. Asbestos may remain in some
older facilities.








Asbestos can be dangerous if not handled properly.
Breathing asbestos dust is hazardous. Asbestos insulation
that is not damaged or friable (hand pressure can
crumble, pulverize, or reduce it to powder when dry)
generally does not produce asbestos fibers at a
dangerous level, especially in non-enclosed structures.










To minimize health risks, it is important not to drill, cut,
remove, tear, step on, brush against, hammer on, or in any
way disturb suspected asbestos. Contact a Chevron
representative if it is necessary to disturb any suspected
asbestos, or if you notice any deterioration in the
condition of the suspected asbestos. Only trained
personnel with proper equipment will disturb or remove
asbestos.



10.3.3 Benzene







Benzene, a liquid found in most crude oil and condensate,
can also be found in produced gas in a gaseous form.
Benzene is known to cause cancer in humans, so it is
important to limit your exposure to it. To know what
benzene concentrations exist and the PPE requirements

82 | GOMBU and DWEP BU



that apply, you should refer to the MSDS for the products
and product streams you handle. Chevron locations
known to have dangerous levels will be posted.






You can reduce exposure and risk by keeping your work
area and your clothing as clean as possible. Leather
gloves or clothing saturated with liquid containing
benzene should be removed and cleaned or properly
discarded to prevent prolonged skin exposure.

10.3.4 Lead






Overexposure to lead can result in serious short-term
(acute) or longer-term (chronic) health effects. Inorganic
lead may be absorbed into the body by ingestion or
inhalation. Lead is most commonly found in paints
and coatings.









Abrasive blasting or burning of painted surfaces probably
pose the greatest potential for lead exposure. Interim
protection must be used until an exposure assessment has
been done to determine whether exposures exceed the
Action Level (AL) of 30 mg/m3 , eight-hour, time-weighted
average, which triggers specific monitoring, training, and
medical surveillance requirements.







The Permissible Exposure Limit (PEL) for lead is
50 mg/m3 for an eight-hour, time-weighted average.
Chevron will inform contractors if lead-based paints or
coatings may be present before soliciting or bidding on
a project.






Contractor companies whose workers will be exposed to
lead must have a written program in place to monitor
their workers’ blood-level exposure. The program will be
reviewed by Chevron before starting the project.

10.4 Heat Stress
Due to environmental conditions in the Gulf of Mexico, heat
can be a major health hazard that should be recognized in
job planning and JSA activities. Contractors are responsible
Contractor Handbook | 83

for ensuring that appropriate controls are identified and in
place to ensure the safety of their employees before
beginning work. Appropriate controls include, but are not
limited to, personnel acclimatization, work mission duration,
and regularly scheduled breaks.

10.5 Fatigue
Worker fatigue can be a factor in incidents or risk to
personnel working under Chevron’s operational control.
When they feel fatigued, workers should notify their
supervisor and handle their fatigue appropriately.
Contractor companies are responsible for monitoring
employee activities and behavior to determine if an
employee should be removed from the work site to obtain
rest or should be given a rest period upon arriving at the
work site before beginning work.
Chevron has adopted the following guidelines developed by
the Joint Contractor Symposium and expects all contract
companies to comply:

• Workers should be limited to 12 to 14 planned work-hours
per day and are not to exceed 16 hours per day,
including travel.



• After two consecutive, 16 work-hour days, contractor
companies will allow workers eight hours of an
uninterrupted rest/sleep period.

• The Chevron work owner, using the Chevron management
of change process, should approve any deviation from
these general guidelines.

84 | GOMBU and DWEP BU

11.0 General Operations
11.1 Lifting of Loads by Personnel
(Manual Lifting Policy)
Employees and contractors must not lift loads over
75 pounds. The contractor must determine whether
assistance is needed to lift lighter weights.
Before lifting, determine the following:

• Can a mechanical device move the object?
• Is the object bulky? Will it obscure vision? If so, get
another person to help carry it.

• Is the object within the contractor’s capability to lift?
• Is the walking surface free of obstructions?
Use proper lifting procedure:

• Bend legs at the knees. Keep the back nearly vertical.
Position the body as close to the object as possible. Place
feet apart, but no more than shoulder width.

• Firmly grasp the object and straighten the legs. Keep the
back straight and upright.

• Pull the object close to the body, leaning back slightly to
keep the center of gravity over the feet.

• Avoid twisting the body when lifting or carrying loads.
• When handling material with others, teamwork is
important. Agree on who will be the leader, and give
signals to indicate instructions. Release the materials only
when everyone is ready.

Contractor Handbook | 85

11.2 Requirements for Third-Party Equipment
Brought to Chevron Facility
11.2.1 General
All equipment delivered to a Chevron shorebase location
must be pre-slung with slings that meet or exceed
Chevron’s sling and shackle policy.
• Make sure that all equipment and materials have the
contractor’s company name clearly and permanently
marked on it.
• Ensure that all equipment is inspected for dropped
object hazards.
• Determine if equipment is fit for purpose and if it has
been adequately maintained with necessary
documentation.
• Ensure that all drain pans are in good condition and are
kept clean and dry with drain plugs wrenched tight.





Engines must have (1) spark arrestors on exhaust,
(2) air intake shutdown devices, and (3) low-tension
ignition systems. Protect hot surfaces against
accidental contact.

• Assure all equipment is NORM-free.

11.2.2 Operating Equipment
Operating equipment typically refers to rotating or
reciprocating equipment, such as compressors, pumps,
pumping units, etc.
• Only trained operators will start and stop operating
equipment.
• Do not wear jewelry, such as rings, watches, wrist
chains, key chains, or loose clothing when working
around operating equipment.
• Confine long hair.

86 | GOMBU and DWEP BU









Do not make repairs to, service, or alter equipment that
is in operation. All equipment must be shut down and an
Isolation of Hazardous Energy (IHE) device used to
prevent accidentally starting equipment while the work
is conducted. Guards and other safety devices will be
fit for purpose and in place before the equipment is
operated.

11.2.3 Pressurized Production Equipment
Only individuals who are qualified in accordance with

30 CFR 250 Subpart O may perform work on pressurized
production equipment.

11.2.4 Repair and Maintenance





Install skillets or other absolute blocking to guard
against leaking valves and inadvertent valve openings,
as required by the Chevron Isolation of Hazardous
Energy program.

• Stand to one side and away from possible flow direction
as flanges are parted or fittings removed.
• Remove swings, ells, and short nipples downstream of
the bleed valve. If turns are necessary, securely anchor
all points where a change of direction occurs.
• Do not hammer lines or fittings under pressure.


11.2.5 Repressurizing






Purge and repressurize lines and equipment slowly and
carefully. Ensure that personnel in the area stand clear
and remain clear of the area until normal operating
pressures are reached.

• Hydrostatically test the lines and vessels when pressure
testing is required.

Contractor Handbook | 87

11.2.6 Valves





Plug valves in hydrocarbon service that open to the
atmosphere with a solid, forged steel plug. Needle
valves with metal-to-metal seats can be used without a
plug, but it is best to plug them when possible.

• Do not hammer valves under pressure.
• Do not use the lower master valve in the day-to-day
operation of wellheads.
• Report leaking or difficult-to-operate valves to your
supervisor so that necessary repairs or replacements
may be made.

11.2.7 Piping
• Only use screwed pipe bushings with two or more
pipe-size reductions (for example, 1 x 3/4 in.) on rotating
or reciprocating machinery in hydrocarbon service.






Tap and equip with a bleed-type steel needle valve with
metal-to-metal seats plugs installed in a line or valve
(with the exception of Kerotest valves) with no means of
depressurization other than loosening of the plug.

11.2.8 Pig Launchers and Traps

• Be aware that NORM may be present and that you
should take proper precautions before receiving
scrapers.






Equip launchers and receivers on in-service pipelines
with a pressure gauge. Alternatively, equip the barrel
with a device that ensures the launcher/receiver cannot
be opened without verifying that pressure has been
released from the barrel.






Consider installing a pressure gauge only during
actual launcher/receiver opening operations in
potential impact areas, such as crane or wireline
operating areas.

88 | GOMBU and DWEP BU

• Stand to the side opposite the launcher or receiver
hinge to prevent injury from trapped pressure.
• Identify the pipes or buildings that the launchers and
receivers serve (e.g., 8-in. Bulk Oil to “B” Structure).
• Depressurize the trap after launching or receiving a pig
whenever a pig trap is left isolated from the production
stream.

11.3 Use of Cheater Bars and Pipes
• Use cheater pipes only when absolutely necessary. The
pipes must be less than twice the length of the wrench
handle and must closely fit the entire length of the
wrench handle.

• Do not jump or jerk on cheater pipes to break
connections.

• Do not use cheater pipes on Crescent®-type adjustable
wrenches.

11.4 Use of Hand and Power Tools
• Refer to the Chevron Non-Welding
Hot Work Plan when using electric
power tools.

• Maintain tools in good condition,
and replace or have defective tools
repaired by qualified personnel.

• Power tools should be included in
a planned maintenance program.

• Power tools should be de-energized
when not in use.

• Use hand tools for their intended





purpose only. For example, do not
use wrenches as hammers or
screwdrivers as chisels or pry
bars. Do not use pipe wrenches on

Contractor Handbook | 89

hex nuts, make sure that grinder wheels are properly
rated for the speed of the grinder, and obey all other
relevant specifications.

• Verify that guards are in place, unaltered, and properly
installed.

• Ensure that power tools are equipped with a three-wire
grounded conductor cord. Use the three-pronged plug
only in a three-prong service outlet.

• Verify that a ground fault circuit interrupter (GFCI)
exists on outlets that are not part of permanent
buildings or structures supplying power to portable
electric tools.

• Most portable electrical or air-operated tools contain a
motor that can generate sparks hot enough to ignite a
mixture of natural gas and air. Use the facility’s Hot Work
Permit process to ensure that these tools are used safely.

11.4.1 Knife Policy
• The contractor company must provide alternative
cutting devices for their personnel to use.

• Contract personnel are not allowed to carry or use
pocketknives or multi-use tools (Leatherman and
Gerber Multi-Plier®, etc.) at offshore locations.

• If a knife is the appropriate tool for the job,
contractor companies are required to provide their
own fixed or locking blade knives and maintain them
for this use.

• If a fixed or locking blade knife is determined to be the
appropriate tool for the task, a JSA must be completed
before its use. Personnel must wear the appropriate
PPE (KEVLAR or leather gloves) during its use.

90 | GOMBU and DWEP BU

11.5 Ladders
• All ladders must be equipped with anti-slip safety feet.
• Do not use ladders as scaffolding components.
• Do not use metal ladders when working with electrical
equipment.

• Allow only one person on a ladder at a time.
• Use, at a minimum, ladders that have the industrial grade
1-A label.

• Inspect ladders before they are used.
• If the ladder is not in a safe operating condition, tag it for
maintenance, and remove it from service.

• Tie/fasten single and extension ladders at the top.

11.6 Working Overhead
Before working overhead, notify anyone who will be below
you. Then, follow these procedures:

• Never throw hand tools or materials to anyone; hand them
up or down.

• When working at heights, handle tools to prevent them
from falling or being dropped.

• Contractors will take all precautions to guard against
falling objects by properly identifying and mitigating
hazards using the Hazard ID Tool.

• Barricades or other suitable safeguards should be placed
below overhead work to prevent personnel from entering
the area below overhead activity.

11.7 Repetitive Stress
Contractors should be trained in and aware of the effects of
repetitive movements during work activities. Observe
caution when performing any task that requires repetition,

Contractor Handbook | 91

so that your body does not experience discomfort. In many
cases, proper handling or using correct posture for certain
tasks will reduce risk.
Employees are encouraged to report early signs of
repetitive stress injuries to their supervisor as soon as
possible.

92 | GOMBU and DWEP BU

12.0 Specialized Operations
12.1 Scaffolding Safety
Scaffolds are temporary elevated platform structures, which
must be provided for all work that cannot be done safely
from ladders or from permanent or solid construction.
Erection and dismantling of scaffolds must be performed
under the supervision and direction of a qualified
person experienced with or trained in scaffold erection,
dismantling, and use, as well as knowledgeable about the
hazards involved.
All scaffolds will be erected, used, and dismantled in
accordance with 29 CFR 1910.28 or any successor
regulation.

12.2 Paint and Blast Waste Media Discharges
Maintenance waste, such as removed paint and materials
associated with surface preparation and coating
applications, must be contained to the maximum extent
practicable to prevent discharge. This includes airborne
material, such as spent or over-sprayed abrasives, paint
chips, and paint overspray. Before conducting sandblasting
or similar maintenance activities, develop and implement a
best management practices (BMP) plan for the containment
of waste materials.

12.3 Sandblasting
The potential hazards during sandblasting operations
include, but are not limited to:

• Inhalation of dusts (including lead from the paint or silica
from the blasting medium)

• High noise levels
• High operating pressure of equipment

Contractor Handbook | 93

Contractors are responsible for appropriate disposal of
accumulations of waste.
The following guidelines minimize the possibility of an HES
incident during sandblasting operations:

• Contractors performing sandblasting operations for
Chevron must have a medical surveillance program in
place to monitor employee’s blood-level exposure to lead.

• Wear approved respiratory and hearing protection.
• Wear appropriate eye protection.
• Sandblasting sand must be double washed to minimize
fires and to minimize exposure to silica dust.

• Consider the paint coatings removed by sandblasting
operations as lead until proven otherwise.

• Check all hoses every day for leaks and signs of wear.
• Maintain adequate ventilation, either mechanical or
natural, to keep the work atmosphere less than a 10%
lower explosive limit (LEL) and the oxygen (O2) content
greater than 19.5% when working in a confined space.

• Bleed or depressurize all lines before disconnecting.
• Use a blasting nozzle with a cutoff device (dead-man’s
switch) in all situations, except underwater grit blasting.

• Secure and hobble all high-pressure air hose connections
using metal whip checks and cotter pin.

• Pin or wire all air hose connectors (crow’s feet) to keep
them from coming apart.

• Post warning signs identifying potential hazards.
• Gather waste over solid decking.

12.4 Painting on Chevron Facilities
Before beginning any blasting and painting work on an
offshore platform, the Operations supervisor or designee
must determine whether the planned activities will require a
Construction Simultaneous Operations Plan and a Daily

94 | GOMBU and DWEP BU

Simultaneous Operations Log. (For copies of these
documents, please contact your Chevron onsite
representative.) In addition, they must prepare a written
JSA with consideration given to the following items:

• Hold daily safety meetings so that personnel can review
activities of the day.

• The paint crew and platform personnel must use PPE
when paint-related products are mixed or applied, if they
are within 50 feet of any work.

• Review the potential health risks during abrasive blasting
operations (e.g., all personnel not wearing forced-air
breathing equipment must stay clear of the area of
operation).

• Store all paints and thinners in baskets or paint lockers
and protect them from their surrounding environment.

• Ensure that any accumulated waste is disposed of
appropriately.

• Take all appropriate measures to minimize waste in
accordance with industry practices.

• Inform the paint inspector and contractor’s supervisor
before intentionally bleeding down any well, piping, or
vessel.

• Protect the detector head and shield assembly from






paints and thinners. Use filter media so the gas detectors
continue to function, but are not exposed to paint when
painting in the immediate vicinity of a combustible gas
detector. Record the time of installation and removal of
this protection in the IHE log.

• Use filter media to protect the internal working
components when painting or blasting in the immediate
vicinity of a panel board.

Contractor Handbook | 95

• Record the time of installation and removal of this
protection in the IHE log when using plumber’s plugs or
filter media to protect drains from blasting media.
Remove the protection at the end of each day.

• The person in charge, the company facilities









representative, or the paint inspector must conduct an
inspection of the location to identify potentially critical
areas associated with blasting lines and vessels before
starting blasting operations. They should give special
attention to areas under or near U-bolts and clamps,
under stainless steel bands, lines at deck penetrations,
threaded nipples, and sections of risers near the
waterline. In addition:

–  They will determine which lines or vessels can be safely
blasted. The determination should be based on the
severity of corrosion, type of corrosion, working
pressure, service, schedule of the piping, and the wall
thickness of the vessel.
–  If necessary, a nondestructive testing crew will be sent
to the location to test ultrasonically or radiographically
potential hazards associated with piping or vessels, to
assist personnel in making a final determination
concerning safety of blasting subject lines or vessels.
–  Lines and vessels that fail to meet maximum allowable
working pressure (MAWP) by nondestructive testing
(NDT) or x-ray (identifying with unique color, if
necessary) must be shut in and bled down before
blasting, replaced or repaired before blasting, or not
blasted and painted.
–  Record the problem area, if not blasted and painted, in a
work order database, such as Enterprise Asset
Management (EAM) or another Computerized
Maintenance Management System (CMMS) system.

• Only platform personnel at the direction of the PIC are
allowed to reroute or relocate emergency shutdown
device (ESD) stations and/or fire-loop lines.

96 | GOMBU and DWEP BU

• Stop all sandblasting and painting in the event of an
emergency or routine shut-in, until the PIC states that it is
safe to restart these tasks.

• Once work has started, the PIC will notify the paint
inspector, the contractor’s supervisor, and the company
facilities representative of any additional potentially
critical lines and vessels observed.

• Protect and/or identify all rupture discs as piped to a safe
location. Record this protection in the IHE log.

• Properly identify and take special precautions to prevent
damage to the micarta ring between the faces of flanges
on insulated flanges installed in conjunction with cathode
protection systems.

• Use suitable filter material to protect air intake of
production/drilling equipment and diving equipment.
The person in charge must advise helicopter pilots and
heliport personnel of the abrasive blasting operations in
process to protect helicopter engines from ingesting
abrasive particles that could damage them. The paint crew
and platform personnel must remove or secure all loose
items in the vicinity of the heliport to prevent items from
being picked up in the helicopter’s blade wash.

12.5 Compressed Air Used for Cleaning
Compressed air used for drying or cleaning must be limited
to 30 psig by a pressure regulator or pressure-reducing
nozzle, as specified in OSHA 29 CFR 1910.242 or any
successor regulation.
Do not, for any reason, direct compressed air toward a
person. Compressed air introduced into the body can cause
injury or death. When using compressed air for cleaning in a
dry and dusty situation, the contractor must wear, at a
minimum, protective eye goggles, gloves, and a dust filter
for respiratory protection.

Contractor Handbook | 97

12.6 Temporary and Permanently Closed
Heliports



The following practice is required when a heliport is
temporarily closed or permanently closed:

• Orange X Marker – An orange X








marked diagonally from corner to corner
across a heliport will be installed to
indicate visually that the heliport is
closed and helicopter operations are not
permitted. The marker must be orange
with legs at least 20 feet long and three
feet wide.

• Permanent Closing – If a heliport is to be permanently
closed, the orange X diagonals must be painted on the
landing area.

• Temporary Closing – An orange X marker will be used







for temporarily closed heliports. The orange X marker
can be made from vinyl or other durable material in the
shape of a diagonal X. The orange X marker will be
removed once the aviation dispatcher and office
assistant (OA) have been notified that the heliport is back
in service.

• Notifications – If a heliport is closed, temporarily or
permanently, the following notification must be made by
the PIC of the facility:

• Aviation dispatcher:
–  Notified of location and estimate of time heliport
will be closed
–  Notified when heliport is put back in service

• Office Assistant:
–  Notified of location and estimate of time heliport will
be closed
–  Notified when heliport is put back in service

98 | GOMBU and DWEP BU

12.7 Perforating Operations – Heliport
Operational Hazard Warnings and
Procedures




Explosive charges used in conjunction with perforating
operations offshore can potentially be detonated by radio
transmissions, including those from helicopters. To prevent
this, the procedures outlined below and the requirements of
the Temporary and Permanent Closed Heliports Operational
Hazard Warning/Procedures HSAC-RP-92-5 must be
followed.

12.7.1 Personnel Conducting Perforating

Operations





Whenever perforating operations are scheduled and
operators are concerned that radio transmissions from
helicopters in the vicinity may jeopardize the operation,
operators will take the following precautions:







Notify company aviation departments, helicopter
operators and bases, and nearby manned platforms of
the pending perforating operation, so the Notice to
Airmen (NOTAM) system can be activated for the
perforating operation and temporary helideck closure.








To close the deck and make the radio warning
clearly visible to passing pilots, install a temporary
marker in the shape of an X with No Radio stenciled
in red on the legs of the diagonals. The letters should be
24 inches high and 12 inches wide. See HSAC RP 92-5
for more information.

• Keep the marker in place while charges may be affected
by radio transmissions.

12.7.2 Pilots





When operating within 1,000 feet of a known perforating
operation, or upon observing the No Radio warning, avoid
radio transmissions from or within 1,000 feet of the
helideck. Do not land on the deck.

Contractor Handbook | 99






Radio transmissions include signals emitted from aircraft
radar and transponders. Use alternate communication
means available on the rig or platform. Turn off Flite Trak
radio.










When possible, make radio calls to the platform being
approached or to the communications center from at least
one mile out. Ensure that all communications are
complete outside the 1,000-foot hazard distance. If no
response is received, or if the platform is not radio-
equipped, do not make further radio transmissions until
visual contact with the deck indicates it is open for
operation (no X marker).

12.8 Subpart O Requirements – Gulf of Mexico
OCS Locations Only
In accordance with NTL No. 2000-N03, dated August 14,
2000, Chevron developed the following to comply with the
requirements of the new Subpart O training rule. Effective
October 1, 2002, the requirements of this subpart have been
fully implemented by Chevron in Gulf of Mexico production
and well control operations.
Both of the following plans were designed to ensure safe
and clean operations, making sure that Chevron employees
and contractors engaged in production-safe systems
operations, drilling, completion, workover, and well
service operations understand and can properly perform
their duties.
Contract employees must be able to provide documentation
of completed Subpart O training; this can be a wallet card or
training certification, as long as it is in the possession of the
employee while on a Chevron location.

12.8.1 Production Operations Plan
The Chevron Employee Resource and Training Center
(ERTC) and designated field locations host training classes
for Chevron employees. The production safety system

100 | GOMBU and DWEP BU







training (PSST) plan uses formal classroom, hands-on,
and computer-based training. Qualified trainers and
training administrators conduct the courses. Employee
records and documentation are readily available upon
BOEMRE request.






Chevron uses one or more of the following assessment
tools to verify that all employees and contractor
personnel can perform their assigned production safety
systems duties:

• Informal employee interviews
• Written assessments
• Hands-on skill demonstrations
• Behavior-based safety observations
Chevron also uses, but is not limited to, one or more of
the following methods to evaluate the training
programs of our contractors:
• Internal audits
• Third-party audits or like reviews
• Master work agreements

12.8.2 Drilling, Completion, Workover, and

Well Service Operations Plan











All Chevron employees or contractors acting as company
representatives will have International Association of
Drilling Contractors (IADC) Well Control Accreditation
Program (WellCAP®) supervisor training as a part of this
competency assurance program. Certain supplier
supervisors and support employees who may be involved
in well control duties will hold certification from an
IADC-accredited WellCAP program. The level of
certification person(s) are required to hold is outlined in
the plan.

Suppliers accredited by IADC in the WellCAP program will
deliver all prescribed training. Qualified trainers and

Contractor Handbook | 101







training administrators will conduct the courses as
specified in the IADC WellCAP accreditation process.
Chevron employee and contractor employee records and
documentation will be readily available upon BOEMRE
request.

Chevron will use one or more of the following assessment
tools to verify that all employees and contractor
personnel can perform their assigned well control duties:
• Informal employee interviews
• Written assessments
• Hands-on skill demonstrations
• Observations during well control drills
• Attendance at well control training

12.9 DOT Operator Qualifications
Chevron wants to ensure that all contractors who perform
any work on DOT-regulated facilities are in compliance with
regulations. Contractor companies unsure if their employees
fall under this rule should contact a contractor safety
specialist immediately. Noncompliance with this rule can
affect a contractor company’s ability to perform work for
Chevron and, potentially, other pipeline owners and
operators.
DOT holds Chevron, as a pipeline operator in the Gulf of
Mexico, responsible for ensuring that all affected personnel
(company and contractor) comply with this regulation. To
ensure compliance, we have identified methods acceptable
to Chevron for employee and contractor record keeping and
qualification.

12.9.1 Record Keeping





Chevron Gulf of Mexico Business Unit and Deepwater
Exploration and Projects Business Unit (GOM and DWEP)
have selected ISNetworld® software from ISN Software
Corp. as our DOT Operator Qualification (OQ) record

102 | GOMBU and DWEP BU

keeping system for contractors and company personnel.
ISNetworld enables you to:
• Work with Chevron to achieve DOT OQ compliance
• Manage your employees’ OQ tasks
• Select and assign the precise OQ tasks and qualification
methods Chevron will accept






Contractor companies should submit their employees’
DOT Operator Qualification records to ISNetworld so that
Chevron can view them as needed. Any questions
regarding how to submit DOT OQ records can be directed
to ISN at 214-303-1303.

12.9.2
Qualification













Operator Qualification Solution Group (OQSG) and
Midwest Energy Association(MEA)/EnergyU.org
provide pre-approved methods of qualification for
contractors in Chevron’s Gulf of Mexico Business Unit and
Deepwater Exploration and Projects Business Unit.
Qualification assessments are available on the Internet,
computer CD-ROM, or written testing. You can learn more
about OQSG, MEA, and EnergyU.org, by visiting their
websites at:

13.0 Drilling and Well Servicing

Operations



13.1 Emergency Drills
Contractor company personnel will regularly conduct all
emergency drills, including fire, man-overboard,
abandonment, and well control, to comply with the
contractor company’s requirements, Chevron’s
requirements, and regulatory requirements. Documentation
for subject drills will be maintained on location.

13.2 Well Control
Chevron’s vision of sustained incident-free operations is
predicated on maintaining well control. It is Chevron’s
expectation that the contractor will ensure that all personnel
will be appropriately trained as per Chevron’s Subpart O
Training Plan for Well Control. Well control drills while
drilling, tripping, etc., will be carried out at a minimum of
three per week for each tour, until crews illustrate
proficiency, then conducted at two per week for each tour.
Drill documentation will be maintained on location.

13.3 Blowout Prevention Equipment Tests
Blowout prevention equipment (BOPE) is emergency
equipment and must be maintained in proper working
condition at all times per Chevron’s Drilling Well Control
Guide and/or Chevron’s Workover Well Control & Blowout
Prevention Guide. The object of BOP testing is to eliminate
all leaks and to determine that the equipment will perform
under threatened blowout conditions. BOP equipment must
be tested when initially installed and every fourteen days
thereafter for drilling operations, or per current BOEMRE
requirements. A seven-day test is required for workover and
cased-hole operations, or per current BOEMRE
requirements. BOP test charts and documentation will be
maintained on location.

Contractor Handbook | 105

13.4 Regulatory Compliance
It is Chevron’s expectation that all personnel will comply
with both company policy and appropriate regulations. The
Incidents of Non-Compliance (INCs) consistently appearing
at the top of the list issued by the BOEMRE include:

• Operations not carried out in a safe, workmanlike manner,
whether due to unsafe actions or unsafe conditions

• BOP equipment, actuations, and documentation
• Area electrical classification infractions
• Pollution, drip pans unplugged, containment, etc.
• Equipment not marked with owner’s name

106 | GOMBU and DWEP BU

14.0 Hydrogen Sulfide (H2S)
Hydrogen sulfide, commonly called H2S, is a highly
poisonous gas. It is a colorless, flammable gas with an odor
like rotten eggs at low concentrations. It is heavier than air
and tends to accumulate in low areas. H2S rapidly deadens
the sense of smell; therefore, smell cannot be used to detect
its presence.
Each platform designated as an H2S facility maintains an
H2S Contingency Plan that includes emergency drills, which
may be reviewed for operational and safety guidelines. Ask
the contractor’s Chevron representative if a work location is
an H2S facility. If contractors detect the presence of H2S,
they must report it to Chevron immediately.
In areas of H2S, contractors will be required to provide proof
of appropriate medical clearance, fit tests, and training.

Contractor Handbook | 107

15.0 Fuels and Gases
15.1 Gasoline
Gasoline is the most widely used flammable liquid. It
generates flammable vapors at ambient temperatures.
Storing, handling, and using gasoline requires
special attention.

15.1.1 Storing and Handling
• Gasoline must not be used as a cleaning solvent.
• Because of its low flash point (-45° F), gasoline presents
a greater potential fire hazard than most other fuels.
For this reason, do not store gasoline in office buildings.
Store containers in their designated place.
• Clearly label gasoline containers.
• Use gasoline only as fuel.
• Gasoline vapors are heavier than air and have a
tendency to collect in low-lying areas. Take special
precautions to ensure proper ventilation when
using gasoline.
• Use gasoline engines only when other power sources
are not available. Acceptable uses are equipment such
as outboard motors, lawn mowers, and chain saws.

108 | GOMBU and DWEP BU



15.1.2 Fueling

Be cautious when fueling gasoline engines. Observe these
guidelines:
• Eliminate sources of ignition, such as open flames. Turn
engines and motors off.
• Do not smoke near fueling operations.
• Make sure the delivery nozzle is in contact with the fill
pipe before starting fuel delivery. Maintain this contact
continuously until the flow stops. If the contractor
ignores this rule, the contractor can create a serious
fire hazard from static discharge generated by
this action.
• Do not fill tanks completely. Allow a minimum of 2% of
the tank space for expansion.
• After the fuel flow has stopped:
–  Tighten the fill cap.
–  Clean spillage.



–  Ventilate areas and check for gasoline vapors before
starting engines or operating equipment.

15.2 Compressed Gas Cylinders
15.2.1
Moving Cylinders
• Transport compressed gas
cylinders in DOT-approved,
corrosion-resistant racks.






Make sure the valve protector
cap is secure before moving
cylinders. Keep the protector
caps in place when cylinders are
not in use.

• Do not use slings, ropes, or chains to lift a cylinder.
• Do not lift cylinders by protector caps.

Contractor Handbook | 109

• Use a hand truck to move cylinders to prevent sliding or
dragging. Securely fasten the cylinders to the hand
truck.

15.2.2
Storage
• Store cylinders in shaded areas.
• Keep caps in place when cylinders are not in use.





Keep compressed gas cylinders at least 20 feet from
highly combustible or flammable materials, such as oil
or chemicals. Alternatively, separate the cylinders with
a metal wall 5 feet high and 1/4 inch thick.

• Do not place compressed gas cylinders where they
might become a part of an electrical circuit.
• Do not expose cylinders to an open flame, a
temperature above 125° F, or an area where heavy
equipment is being moved.
• Do not use compressed gas cylinders as rollers or
supports, or for any purpose other than to contain the
content as received.
• Secure cylinders upright with a nonflammable device to
prevent them from being knocked over or damaged. Do
not use rope to secure cylinders.

15.2.3
Use
• Cylinders must be secured and protected from impact,
including falling objects, while in use.





Keep the cylinder valve closed, except when the
cylinder is in active use. Open the valve slowly with the
valve pointing away from the contractor and other
personnel.

• Do not use compressed gas for cleaning, because it may
injure the eyes or body or create a fire hazard.
• Do not use cylinders that have been defaced, are
missing identifying markings (labels, decals, tags), or
have expired hydrostatic test dates.

110 | GOMBU and DWEP BU






Use regulators, gauges, and hoses only for the
particular gas or group of gases for which they are
provided. Do not use them on cylinders containing
gases with different properties.

• Use properly fitted and recommended wrenches with
cylinder-valve accessories. Do not use these wrenches
for any other task.
• Install flashback arrestors at the discharge of the
regulators and at the torch. This is a requirement.

15.2.4 Oxygen Cylinders
Oxygen cylinders are pressurized to 2,400 pounds-per-
square-inch-gauge (psig) at 70° F when full. Oxygen
alone will not burn; however, it supports combustion.





Do not lubricate or allow oil or grease to contaminate
oxygen connections to prevent spontaneous explosions
and fires that may occur when oxygen contacts oil or
grease under pressure.

• Separate oxygen and hydrocarbons.
• Do not use oxygen in place of compressed air or as a
source of pressure.
• Separate oxygen cylinders and fuel-gas cylinders (such
as acetylene, propane, and propylene) by at least
20 feet or by a metal wall 5 feet high, 1/4 inch thick, and
as wide as the storage rack.

15.2.5
Acetylene Cylinders
• Use and store acetylene cylinders upright to prevent
the acetone (a stabilizing agent) from draining into the
valves or fittings.





Do not use acetylene at a hose pressure exceeding
15 psig to reduce the possibility of an explosion.
Acetylene is extremely unstable at pressures above
15 psig.

Contractor Handbook | 111



15.2.6 Natural Gas

• Do not use natural gas to power pneumatic tools.
• Do not use natural gas in areas that have an ignition
source.
• Vent pump and starter exhaust to a safe area. Do not
vent or exhaust to confined areas, enclosures, or areas
where the gas can be trapped.
• Do not use rubber hoses as supply or exhaust lines for
natural-gas-powered equipment.
• Isolate natural gas and air supply systems from each
other. Never commingle natural gas and air supply
systems.





Install an odorization unit in the gas line before it enters
the building, so that a leak can be detected when
natural gas is used for domestic purposes inside
buildings (e.g., in stoves and heaters).

112 | GOMBU and DWEP BU

16.0 Safe Work Practices
The Safe Work Practices process applies to all GOM facilities.
As stated in the Contractor Safety Management process,
contractors are required to follow their own Safe Work
Practices. Where permits are required from either a Chevron
or contractor’s process, they will be reviewed by the
Chevron person in charge.
https://upstream.chevron.com/contractorgom/
Managing the Safe Work Process
The success of the Managing Safe Work (MSW) process
requires that supervisors at every level understand their
roles and responsibilities in MSW and translate them into
actions and behaviors that are visible to the Chevron
workforce (including contractors). Recognizing that
behaviors to support MSW are part of leadership
accountability in the Operational Excellence Management
System (OEMS), this procedure provides guidance to the
strategic business unit (SBU) by identifying behaviors at
every level of supervision specific to supporting MSW.
The following describes the relationships between this
procedure and other behavior-shaping processes currently
used by Chevron:
1.






Behavioral-Based Safety (BBS) – BBS is focused on
shaping behaviors to ensure the safety of the individual
performing work. The Behaviors to Support MSW
procedure is focused on shaping behaviors of
supervision at each level to ensure that MSW
procedures are followed without fail.

2.





Incident- and Injury-Free (IIF) – The IIF program
focuses on personal commitment, developing
relationships, and acting in a safe and caring fashion. It
assumes that processes and procedures for managing
safe work are in place. The MSW process identifies and

Contractor Handbook | 113

requires that procedures for managing safe work are in
place. Behaviors to Support MSW procedure ensures
those procedures are followed.
The MSW process requires each SBU to establish a
measurement and track behaviors with appropriate
accountability. The Behaviors to Support MSW procedure
recognizes SBU responsibility for establishing accountability
and provides a framework to collect data to assist in that
effort. The SBUs are encouraged to leverage existing
activities for data collection and may incorporate that data
into existing scorecards where appropriate to enhance
leadership accountability.
GOM Safe Work Practices
• Permit to Work
• Isolation of Hazardous Energy
• Work at Height
• Simultaneous Operations
• Hot Work
• Excavation
• Electrical Safety
• Confined Space
• Lifting and Rigging
• Bypassing Critical Protections

16.1 Permit to Work Process
The Permit to Work (PTW) Process, a formal written process,
is also a means of communication between responsible
persons, such as supervisors, team leaders, operators,
contractors, and others involved in the planning and
execution of work tasks. It is vitally important that each
individual knows his/her own responsibilities and duties and
carries them out properly.

114 | GOMBU and DWEP BU

Contract companies are expected to have a PTW process in
place. There may be situations where the contractor will be
required to comply with the Chevron PTW process on
Chevron facilities. Consult the Chevron work owner to
determine the requirements before starting work.
The main functions of the PTW Process are to:

• Ensure the proper authorization of designated work.
–  Make clear to people carrying out the work the exact
identity, nature and extent of the job, the hazards
involved, and any limitations on the extent of the work
and the time during which the job may be carried out.
–  Specify the precautions to be taken, including safe
isolation from potential risks such as hazardous
substances and electricity.
–  Provide a procedure for times when work has to be
suspended, i.e., stopped for a period before it is
complete.
–  Provide for the cross-referencing of safe work practices
and associated permits for work activities that may
interact with or affect one another.
A Permit to Work will be required for the following:
–  Specialized work permits are initiated (e.g., Hot Work,
Confined Space, Isolation of Hazardous Energy,
Excavation, Work at Heights, Electrical, SIMOPs, etc.).
–  Work or maintenance is performed in a process area
that involves breaking into a line, equipment, or vessel
that contains actual or potential hazards.
–  There is a transfer of work and responsibilities from one
group to another.
–  Communication across more than one area, group, or
technical type is required to accomplish the task.
–  If the area controller determines a permit is required.
–  The work has significant potential for injury or incident.

Contractor Handbook | 115

–  When synthetic slings are used in marine operations
involving crane activities.

–  Boats are arriving within 500 meters of the facility
(Floating Offshore Installations).
–  Boats are transferring diesel fuel, synthetic base mud,
or other hazardous materials to the facility.
–  During liftboat moves, liftboat guidelines and
procedures are the standard operating procedure for
liftboat operations in all fields. Review Lift Boat
Guidelines and Procedures before all liftboat moves.
–  Before blasting and painting and production wireline
and construction activities, complete and attach the
Hazard Identification Checklist (available on the external
contractor website) to the Permit to Work form.
Note: Do not use routine vs. non-routine work as a

criterion for determining when the Permit to Work

is needed.
–  Refer to the PTW/SimOps Decision Matrix (available on
the external contractor website) to help determine if
only a Permit to Work is needed or a Permit to Work
and SimOps.





The Decision Matrix captures the majority of
circumstances that require a Permit to Work.
However, not every scenario can be predicted.
Many situations will have to be evaluated individually.

The person leading work (PLW) is normally the company or
contract representative in charge of the crews doing the
work. For each permitted work activity there will be a
designated person to lead the work. That person leading
work could be a company or contractor operations
representative, facility representative, paint inspector, crew
superintendent, Instrumentation and Engineering (I&E)

116 | GOMBU and DWEP BU

representative, wireline operator, crafts person, X-ray
technician, etc.

• The PLW is on location and acknowledges that all permit
conditions in Section B of the PTW form are met, and the
work site has been inspected before beginning work.

• The PLW is a competent individual assigned the
responsibility of verifying the work site activities are in
compliance with the permit conditions.

• The PLW is a competent individual responsible for the safe
execution of the work.
Behaviors of the Person Leading Work:
–  Sets expectations
–  Plans the work with the team
–  Collaborates and coaches throughout the job
–  Provides performer feedback

16.1.1 Hazard Analysis
Introduction
















This procedure follows the three
phases of hazard analysis as it
applies to our work. From the initial
planning phase, to the work group
pre-job onsite Job Safety Analysis
(JSA) discussion, to the individual’s
ongoing effort to Think Incident
Free (TIF), hazard analysis tools are
critical to identifying potential hazards and developing
actions and strategies to prevent incidents from
occurring. Hazard analyses may also be used as a training
tool for new employees, as the basis for HES checklists,
BBS observations, and safety meeting topics and to write
HES procedures and standard operating procedures
(SOPs) for new or modified jobs.

Contractor Handbook | 117



16.1.2 Requirements








A hazard analysis will be conducted for work performed
where Chevron has operational control. For contractor
activities where Chevron does not have operational
control, we will encourage them to use their hazard
analysis tools. The Use of Analysis Methods table lists the
methods discussed in this procedure.

Contractor Handbook | 119

16.2 Planning Phase Hazard Analysis
The hazard analysis performed as part of job planning
provides a structured approach for identifying potential
hazards and developing control measures. This should
ensure that the proper people, equipment, preparation, and
HES processes are identified and acted upon before
commencing work. This also provides the opportunity to
adjust the work plan to reduce risk.
A qualified standard operating procedure (SOP) may be
used as the hazard analysis for job planning. SBUs should
consider incorporating a completed hazard analysis into new
and existing SOPs.
Job Safety Analysis
The JSA is a tool for analyzing a task, specifically in the area
of health, environment, and safety. This analysis occurs at
the work site before work begins and involves those
individuals that may be affected by the task. The JSA should
identify the hazards present at the time the work starts as
well as identify specific mitigation actions necessary to
prevent incidents. After the analysis is done, it may be kept
as a reference for future similar operations. Since the JSA is
a tool intended for individuals and teams performing the
work, it should be developed in the language appropriate for
the entire work crew (sometimes multiple languages and/or
verbal translation may be needed).

16.3 Think Incident Free
Think Incident Free should be used by everyone before
beginning any activity. These self-assessments focus on the
fact that each worker must take responsibility for his or her
own health and safety in all activities, as well as protect the
environment. Many tasks have risks associated with them
that could potentially result in injuries, environmental
impact, and losses. Before these risks can be eliminated or
controlled, they must be identified. TIF enables employees

120 | GOMBU and DWEP BU

to observe day-to-day operational and procedural systems
to identify potential hazards that could threaten the health
or safety of our personnel or contract workforce, company
facilities, or the environment.
The steps in an effective TIF assessment are:

• Determine the potential hazards.
• Determine what can be done to eliminate the hazard.
• Take action to prevent any negative consequences.
SBUs may use other nomenclature and/or tools for their
TIF assessments.

16.4 Hazard Analysis Content
A hazard analysis is not:

• A detailed work procedure (either maintenance or
operating).

• A Permit to Work, and a PTW is not a JSA.
• A recyclable document (it must be refreshed for each job).
Items that should be included in the different levels of
hazard analysis are listed in the Hazard Analysis Content

16.6 Hazard Identification – Using the Tool
The Hazard Identification Tool is a visual aid that will help
you focus on hazards associated with your work. This tool is
used to identify energy sources in the workplace that could
result in a hazard to people, the environment, or equipment.
This is not new; this is just a systematic approach to
correctly and consistently identifying workplace hazards.
Using this method will help you complete daily activities and
tasks safely and reliably.
The concept is very simple: you identify what energy
sources are present in the work place and analyze if they
have any potential for causing harm. Once the hazards are
identified, you can take actions to prevent their occurrence.
The Hazard Identification Tool easily integrates with existing
hazard assessment methodologies such as JSA, Safe
Performance Self-Assessment (SPSA), Job Safety Evaluation
Assessment (JSEA), JHA, Task Hazard Analysis (THA), TIF,
Job Loss Analysis (JLA), etc.

16.7 Hazard Identification – Chevron’s
Expectations
It is Chevron’s expectation that all our employees and
contractors will use the Hazard Identification Tool when
identifying hazards associated with work to be completed.
Use this tool from the initial planning phase, to the
permitting phase during the work group’s pre-job onsite
Job Safety Analysis, to the implementing phase with the
individual’s ongoing effort to Think Incident Free.
The Hazard Identification Tool is critical to identifying
potential hazards and enables the development of actions
and strategies to prevent incidents from occurring.

16.8 Isolation of Hazardous Energy
Each contractor company must have an Isolation of
Hazardous Energy process in place, and the company must
train its employees in using the process per applicable
regulations, laws, or policies.

16.8.1 Isolation of Hazardous Energy Procedures

on Chevron Facilities


















The contractor will, at a minimum,
follow the Chevron Isolation of
Hazardous Energy Plan. Whenever
a contractor’s Isolation of
Hazardous Energy Plan is more
stringent, this will be addressed
during the pre-job meeting, JSA
development, and/or completion
of the Permit to Work. If the contractor’s Isolation of
Hazardous Energy Plan is used, a Chevron Operations
lock will be the first lock on before turning the equipment
over to the contractor and the last to be removed upon
completion of the work. All contractors performing
Isolation of Hazardous Energy must be fully trained and
authorized before conducting Isolation of Hazardous
Energy activities, and proof of authorization must be
provided to Chevron.






Contractors will apply their own locks in addition to any
Chevron locks and tags already in place. If they do not
have their own locks/tags, they will be issued facility
Isolation of Hazardous Energy equipment.

16.8.2 Use of Lockboxes
For a large job, a lockbox may be used in lieu of a lockout
bar clip.
• Lockbox procedure may be used when energy sources
or a group of employees are involved in maintenance or
repair operations.

Contractor Handbook | 129









Under a lockbox procedure, the primary authorized
employee will place an Isolation of Hazardous Energy
device upon each hazardous energy/substance isolation
device. The keys from these locks will then be placed
inside a lockbox. Each authorized employee assigned
to the job will then affix his/her personal lock on
the lockbox.

• As a member of a group, each assigned authorized
employee verifies that all hazardous energy has
been isolated and/or de-energized.






The Isolation of Hazardous Energy devices will not be
removed or the hazardous energy/substance device(s)
activated until after each authorized employee has
removed his/her lock from the lockbox and the Isolation
of Hazardous Energy device(s) are removed.

• When the maintenance work extends beyond one shift,
attach a job-lock to the lockbox.

16.9 Work at Height
The primary objective of the Work at Height Plan is to
prevent incidents and injuries caused by falling through
floor and deck openings or by falling while working at
elevations. This plan applies to both Chevron and contract
personnel conducting work on Chevron facilities, including
all OCS, state, and land-based locations.
This plan does not apply on drilling rig floors and derricks.
Drilling contractors will employ adequate procedures that
are designed to protect their personnel against falls.
For operations on vessels (MODUs, liftboats, and other
self-propelled boats), contractors will employ adequate
safety procedures designed to guard against falls.

130 | GOMBU and DWEP BU

16.9.1 When Fall Protection/Arrest Equipment

Is Required
Personnel must use fall protection equipment when
performing any of the following:
• When working at elevations of six feet or more, or over
the unprotected edge of a work platform, deck,
walkway, or floor
• When working in an area where it is possible to fall
more than four feet through deck and floor openings
• When working on a fixed or portable ladder and the
worker is above six feet
• When working on the boat landing or Plus 10 level when
not surrounded by handrails
• When working on scaffolding that is not green-tagged
Note: Individual contractors may require personnel to

tie off even if scaffolding is green-tagged.


16.9.2 Specifications







Chevron’s GOM business unit is changing its Work at
Heights policy effective January 1, 2011. The changes are
being implemented to minimize the possibility of
accidental disengagement commonly referred to as “roll
out.” The three (3) components of the policy that will be
affected are as follows:

• A minimum size requirement for all D-rings on
equipment including harnesses
• Snap hooks that do not allow pressure to be applied to
the gate in the opening direction
• The elimination of a specific piece of equipment

Contractor Handbook | 131

After January 1, all D-rings
must be a minimum of 2¼-in.
inside diameter (ID).
Smaller sized D-rings can allow
pressure to be applied to the
snap hook gate in the opening
direction. Small D-rings
are often used as a front
connector on harnesses for
rescue and or ladder-climbing
devices.

2. The change to a 2¼-in.
D-ring, combined with a hook
that does not allow pressure to
be applied to the gate in the
opening direction, will eliminate
accidental disengagement. In
lieu of a snap hook, carabiners
may also be used as connection
points for all equipment.

Non-compatible

3. The final change is the
elimination of the pelican hook
on lanyards. These hooks are
acceptable as a positioning
device but may not be used
as a primary means of
connection.
In lieu of the pelican hook, workers
may either equip lanyards with
carabiners as shown on the next
page or use a tie-back lanyard. The
tie-back lanyard must be equipped

D-ring and a hook or other
connecting means that cannot
apply pressure to the gate in the
opening direction.

16.9.3 Required
Documentation
Before beginning work that
involves the use of fall protection,
personnel must complete or verify
the following:

Pelican hooks are no
longer permitted
captive eye

• Permit to Work
• Fall Protection Checklist
• Rescue plan
• Inspection forms

Carabiner with

A rescue plan must be developed
captive eye
and included in the JSAs for jobs
requiring the use of fall protection
equipment. Each contractor must be able to provide
verification of an annual inspection for all equipment
onsite. The inspection forms may be hard copy or
electronic and must be available upon request from the
contractor’s HES group.

16.9.4 Training Requirements
GOM Fall Protection required training for contractors is
as follows:

• One-Day Fall Protection class (typically eight hours) for
employees that use fall protection equipment, which
includes hands-on use and demonstration of
competency by the student

• Two-Day Competent Person training for at least one
person per crew onsite

Contractor Handbook | 133

• Rescue training for at least one
person per crew onsite.
• Verification of Contractor Fall
Protection training:
–  Onsite documentation may be
requested from contractors to
provide verification of
compliance with Chevron requirements.
–  If discrepancies are identified, a review of the
contractor’s fall protection training/training provider
will be conducted to ensure that it meets Chevron’s
expectations/training criteria.







If observations performed during climbing activities
indicate less than satisfactory performance, Stop-Work
Authority may be exercised and a review of Chevron
expectations will take place. If agreement to proceed is
not reached, a review of the contractor’s training and
policy will be initiated.

16.9.5 Open Hole






The primary objective of Guidelines for Guarding Deck
Openings is to prevent incidents and injuries caused by
falling four feet through deck and floor openings, or
falling from open-sided floors, platforms, or runways at
elevations of six feet or more.







Openings smaller than 1 ft x 1 ft are not required to
meet these guidelines; but it is recommended, however,
that any opening that presents a potential hazard be
guarded to prevent a person’s foot or body from
inadvertently passing through the opening.

For cases where fall protection equipment is required, see
section 16.9 Work at Height standard.

134 | GOMBU and DWEP BU

16.9.6 Openings in Decks







Personnel will wear fall arrest equipment when making
an opening in the deck or floor. Openings in decks
accessible to personnel will be covered, guarded, or
otherwise made inaccessible. The manner of blockage
will prevent a person’s foot or body from inadvertently
passing through the opening.

Unintentional openings in decks accessible to
personnel will be covered, guarded, or otherwise made
inaccessible immediately and reported to the PLW.







Every deck opening into which personnel can accidentally
walk will be guarded with a guardrail or covered with a
floor-hole cover of standard strength and construction.
Although an attendant is acceptable under 29 CFR
1910.23, Chevron does not allow for a “hole watch” in lieu
of guardrails.






When possible, open holes will have guardrails installed
five feet from the closest edge. Personnel are required to
wear proper fall arrest equipment when working inside
the guardrail used to protect the hole.

16.9.7 Requirements for Guardrails
Guardrails will meet the requirements of 29 CFR 1910.23.
The minimum requirements of OSHA regulations are as
follows:
• Minimum vertical height of 42 inches to the top of the
guardrail.
• Guardrail is capable of supporting a load of at least 200
pounds applied in any direction (except upward) at any
point on the top rail or corresponding member.

Contractor Handbook | 135

• Guardrail has a standard toeboard and intermediate rail
or fencing from top to bottom. Examples of fencing
materials are chain link and orange safety netting.

16.10 Simultaneous Operations
16.10.1 Simultaneous Operations Plan
A Simultaneous Operations Plan will be required when:
Two or more of the following operations are performed
concurrently:
• Production operations
• Rig operations
• Construction operations
• Anchoring of vessels
• Derrick barge operations
• Heavy lifts
• Diving operations






Production activities concurrent with construction
activities only require a Permit to Work, but depending
on specific hazards and complexity of the project as
identified by the Field Management team, SimOps
procedures may be required.

Refer to the PTW/SimOps Decision Matrix to help
determine the need for using Permit to Work only or
Permit to Work and SimOps.
All SimOps plans will be used in conjunction with the
Permit to Work process.

136 | GOMBU and DWEP BU

16.10.2 Simultaneous Operations
Documentation/Communication
Simultaneous Operations Plan Form
Complete the form before starting SimOps activities.
• Responsibility of the project initiator: Operations
engineer, drilling engineer, facilities engineer,
operations supervisor
• Is a bridging document to help create a tangible plan
including completion of a Risk Assessment
• Designates the responsible parties for the various
operations being performed
• Establishes emergency response awareness and
contacts
• Identifies hazards and appropriate mitigations
(precautions and actions)
• Clarifies communication between the various
operations
Simultaneous Operations Plan Checklist
Complete the checklist before startup and weekly
thereafter.
• Responsibility of PIC: Facility representative,
drillsite manager, wellsite manager, operations
supervisor
• Must be used to ensure compliance with the
Simultaneous Operations Plan
• Completed by the PIC and members of the
Field Management team (FMT)
SimOps Meetings – Daily
• Responsibility of the PIC


Contractor Handbook | 137

Simultaneous Operations Log – Daily
• Responsibility of the PIC.
• Used to document the discussion of projected activities
of the day.
• Used during all simultaneous operations and is
completed daily by the PIC.
• A copy of the log is provided to the Operations
supervisor.
• The Operations supervisor is responsible for

conducting a weekly review of the Daily Simultaneous
Operations Log.
This process does not preclude establishing more restrictive
limitations that may be warranted by particular
circumstances or conditions.
The key element during simultaneous operations is
communication. It is imperative that clear and continuous
communication is maintained between company and
contract personnel onboard. This communication will be
established at the outset of simultaneous operations and
maintained daily through both normal and abnormal
conditions and documented on the Daily Simultaneous
Operations Log.
SimOps should be discussed daily at all shift/pre-tour
meetings. One way to provide the best communication
during simultaneous operations is to maintain the same
drilling, production, and construction personnel throughout
the entire project.

16.11 Hot Work
All contractor employees working on a Chevron location or
under Chevron’s operational control must be aware of
potential operations and ignition sources that may require a
permit, as well as the process required to obtain this permit.

138 | GOMBU and DWEP BU

Contractors performing hot work on Chevron property are
required to follow Chevron’s approved BOEMRE Hot Work
plan while performing any welding or burning, and any
associated grinding or non-welding hot work (all other
ignition sources). A copy of this plan and BOEMRE approval
letter is available at all manned facilities.
The Chevron representative is responsible for coordinating
the issuance of the Daily Welding Permit or the Daily NonWelding Hot Work Permit, and for getting all appropriate
signatures as required.
Welding in, or on, any tank, vessel, or piping connected to
the tank or vessel requires special planning, procedures, and
project execution requirements. When contracted to
perform this task, contractors should work closely with
Chevron personnel and project planners to assure that all
safeguards and procedures are in place and are followed.
Contractors working under Chevron’s operational control at
locations other than on Chevron property are required to
have a hot work program that ensures that this kind of work
can be conducted safety and in compliance with local rules,
regulations, and requirements. All contractor employees
performing hot work must be trained in this program and
able to conduct these operations safely.

16.12 Fire Prevention
Fire prevention is vital to safe operations.

16.12.1 Fire Retardant Tarps (Chevron GOM

Facilities Only)





The GOMBU has determined that all tarps used in hot
work and purchased for offshore, no matter whether or
not for hot work purposes, will be fire-retardant (FR)
tarps and will meet the following specifications:

• Be red in color

Contractor Handbook | 139




Have fire-retardant label or tag



Have grommets

Be silicone-coated or silicone-impregnated (to keep the
material from becoming airborne or friable)






16.12.2 Fire Watch












A fire watch is a person adequately
trained, capable of, and solely
designated to operate gas
detection and incipient firefighting
equipment during all welding and
burning operations performed
outside approved designated
safe welding areas. The fire watch
assists the inspection of the
work area.






During all welding, one or more persons must be
designated as a fire watch. Separate fire watches must be
stationed at each area where welding is in progress and
must have no other duties while standing watch.

Specific requirements for fire watch include:












Before any welding, have usable fire-extinguishing
equipment readily available and be trained in its use.
Fire watch will not rely on production facility-mounted
fire extinguishers as the primary fire extinguisher. A
separate fire extinguisher needs to be provided as part
of the job planning for the fire watch to use as the
primary, with the facility fire extinguishers used only if
there is a problem with the primary. The extinguisher
must be metal and meet the requirements of the job. It
must be inspected before each use and have the proper
inspection tag.

• Be familiar with the facility’s Emergency Response Plan
and procedures for sounding an alarm in the event of
a fire.

140 | GOMBU and DWEP BU

• Wear proper PPE including but not limited to UV arc
protection.






Perform continuous monitoring with a portable gas
detector before and during welding. Hot work is
prohibited when the presence of a flammable
atmosphere greater than 10% of the lower explosion
limit (LEL) is detected.

• Remain on duty for 30 minutes after welding ends.

16.12.3 Ignition Sources





Contract personnel should be aware of typical ignition
sources, such as welding arc cutting torches, electric
power tools (such as drills, sanders, and grinders), dew
point testers, and lighters.

Pneumatic tools that chip, gouge, grind, or drill are also
ignition sources that require the use of hot work permits.
If there is any doubt whether a piece of equipment can
ignite an air-natural gas mixture, contact the contractor’s
supervisor for guidance.
Some specific ignition sources that are not hot work-
related are described below.
16.12.3.1 Personal Electronic Devices







Personal electronic devices
(phones, pagers, cameras, and
computers) may require a
non-welding hot work permit
approved by facility
management.









Unless cameras have been
properly evaluated, they are
assumed to be an ignition source (particularly those
cameras with flash attachments or motor drives). Do
not use them in or around production or drilling
operations without prior approval of the person
in charge.
Contractor Handbook | 141

16.12.3.2 Flashlights





Use flashlights approved by a recognized testing
laboratory, such as Underwriters Laboratories (UL), as
suitable for Class I, Division 1 or Division 2 Group D
hazardous (classified) locations.

16.12.3.3 Portable Communication Radios





Use portable communication radios approved and
identified by a recognized testing laboratory, such as
Underwriters Laboratories as suitable for Class I,
Division 1 locations.

16.12.3.4 Other Electronic Equipment








Many types of electronic equipment are not intrinsically
safe. When using non-intrinsically safe equipment, take
the same precautions as used during welding
operations and complete and obtain approval for a
non-welding hot work permit. If contractors are in doubt
about the equipment, they should ask the contractor’s
supervisor for guidance.

16.12.4 Use of Solvents






Do not use gasoline, Varsol® mineral spirits, or any
other flammable liquids as a cleaning fluid. Aircraft
maintenance is excluded from this guideline. Painters
are excluded from this requirement only when cleaning
their paint-spraying equipment.







Use commercial fire-safe solvents for cleaning
mechanical equipment. A safe solvent is a class IIIA
liquid; it has a flash point above 140° F and below
200° F. If in doubt about fire-safe solvents, consult the
profit center’s safety representative.

• Refer to the MSDS for safety precaution information
and for guidelines about the proper PPE to use when
handling solvents.

142 | GOMBU and DWEP BU



16.13 Electrical Safety

16.13.1 Electrical Safe-Work Practice












Each contractor company must
have an electrical safety
awareness program in place, and
the contractor company must train
its employees per applicable
regulations, laws, or policies. At a
minimum, this training must include
the following topics. However,
contractor employees required to perform work on
electrical installations may need additional training and/or
certifications as determined by the contractor company.








Do not work on or alter electrical circuits, extension
cords, tools, or any other types of electrical equipment,
unless you are qualified to do so. Individuals performing
electrical work must be able to meet the competency
requirements and have personal PPE and tools needed
to perform a specific task.

• Be cautious when working around electrical equipment.
• Do not touch electrical equipment while standing in
water, on metal floors or ladders, on damp concrete, or
on other well-grounded surfaces.
• Do not operate electrical equipment when your skin
surfaces are damp or when you are wearing wet shoes
or damp clothing.
• Post caution signs on electrical equipment for voltages
of 600 volts and below.
• Post danger signs on electrical equipment for voltages
above 600 volts.
• Follow the appropriate Isolation of Hazardous Energy
procedure when working on any electrical equipment.
• All work is to be done in a de-energized state.

Contractor Handbook | 143

• Use explosionproof and non-sparking tools and
extension cords where potentially explosive
atmospheres exist.


16.13.2 Electrical Fuses






Testing for the absence of voltage is an essential part of
establishing an electrically safe work condition, and
requires employees demonstrate the ability to use
voltage detectors.

• De-energize circuits by using Isolation of Hazardous
Energy procedures before replacing fuses.
• Do not bridge fuses or circumvent the normal operation
of circuit breakers.





Do not replace blown fuses with fuses having a higher
amperage or lower voltage rating. To maintain proper
circuit protection, only qualified workers will replace
blown fuses.

• Use a fuse puller to remove cartridge fuses.

16.13.3 Extension Cords





Use extension cords only in temporary situations. Use
proper construction methods to create permanent
electrical connections where more than temporary
needs exist.







GFCIs on all cord-connected electric power tools and
other cord-connected devices are required. These
whip cords (not more than 2 feet in length) should be
plugged directly into the premise receptacle if non-
explosionproof.








Where premise wiring connections originate at an
explosionproof receptacle, an explosionproof adapter
cord (not more than 2 feet) should be used, power
extended to the work site using suitable extension cord,
with a GFCI whip cord connected for equipment
connections at the hazardous area.

144 | GOMBU and DWEP BU

• Always test GFCIs immediately before use to ensure
proper working order.
• Protect cords against contact with oil, welding hoses,
chemicals, and hot surfaces.
• Do not hang cords over nails or sharp edges. Do not
place them where vehicles may run over them.






Always connect the non-explosionproof connection
first and disconnect it last when using adapter cords,
such as pigtails. For more information, refer to the
Chevron Non-Welding Hot Work Plan notes section on
page 3.

Inspect all extension cords before use. Address the
following items during the inspection and take appropriate
action to use the extension cord:
• Use extension cords in classified areas that are
designed for explosionproof service.
• Do not connect multiple cords to extend the length.
• Discard cords found with abrasions, cuts, or repairs
covered with electrical tape.
• Make and break all connections under zero energy
state.
• Tape connections with electrical tape when connecting
electrical tools and whips for shock protection.
• Do not place cords in walkways or areas that impose a
tripping hazard.

16.13.4 Static Electricity
• Electrically bond barges and trucks to loading or
unloading lines before connecting hoses and opening
hatch covers.
• Bond nozzles to the vessel first if using steam or water
to clean oil storage tanks and separators.

Contractor Handbook | 145

• Use antistatic sandblasting
hoses, or electrically bond
the nozzle to the vessel being
blasted.

NO
SMOKING
FLAMMABLE

• Do not use plastic buckets to











collect hydrocarbons. A metal
bucket with a metal handle is
acceptable, as long as the
handle does not have a plastic
or wood grip. Plastic or wood
grips prevent buckets from
bonding to the valve or other
metal parts, and the static
charges generated cannot
dissipate.

Onshore – bury rod
8-feet deep to

facility

16.14 Confined Space
Each contractor company must have a Confined Space Entry
program in place, and the contractor company must train its
employees to use the process per applicable regulations,
laws, or policies. At a minimum, this training must include
the ability to recognize a confined space and an awareness
of the requirements for entering.
Work in a confined space is allowed only after the
appropriate permits are obtained and training is completed.
Confined space is defined as a space that:

• Is large enough and so configured so that an employee
can enter the space and perform the assigned work.

• Has limited or restricted means for entry or exit
(e.g., tanks, vessels, silos, storage bins, hoppers, vaults,
and pits).

• Is not designed for continuous employee occupancy.
When a contractor enters a permit-required space, both
Chevron personnel and the contractor have responsibilities
as outlined in the following section.

146 | GOMBU and DWEP BU

Permit-required confined space is a space that has one or
more of the following characteristics:

• Contains or has the potential to contain a hazardous
atmosphere

• Contains a material that has the potential to engulf
an entrant

• Has an internal configuration where an entrant could
be trapped or asphyxiated by inwardly converging walls or
by a floor that slopes downward and tapers to a smaller
cross section

• Contains any other recognized serious safety or health
hazard

16.14.1 Chevron Responsibilities
Chevron has these responsibilities when someone enters a
permit-required space:





Assign a Chevron onsite representative to provide
oversight during the entry. This person must be
qualified to oversee work in confined spaces either
through training or experience.

• The platform operator must review and sign the
Confined Space Permit before work begins.






Take effective measures to prevent entry by
unauthorized personnel. If inspection or work
verification requires entry by Chevron personnel, each
person entering must be trained as an authorized
entrant.

• Make visitors aware of permit-required confined space
activities.
• When personnel perform work that involves permit-
space entry:
–  Select a qualified contractor to perform entry work.
–  Using the Permit to Work process, obtain approval for
a plan for isolating, cleaning, and entering the
confined space.
Contractor Handbook | 147

–  Using the proper Isolation of Hazardous Energy
procedures, isolate, lock, and block all potential
sources of energy and contamination.
–  Empty or drain the confined space of liquids and
gases that are flammable or toxic.
–  Turn the confined space over to a qualified contractor
to perform assigned work.
–  Inform the contractor of the elements associated with
the hazards that make the space a permit space.
Provide copies of all MSDS associated with the prior
contents.
–  Inform the contractor of any precautions or
procedures (such as Isolation of Hazardous Energy)
that Chevron has implemented for the protection of
employees in or near confined spaces where
contractor personnel will be working.
–  Coordinate entry operations between Chevron and
contractor personnel when Chevron personnel will be
working near confined spaces.
–  Appoint the prime contractor to govern and
coordinate entry operations when more than one
contractor is participating in entry operations.
–  Debrief the contractor at the conclusion of the entry
operations. In brief narrative form, identify all
hazards confronted during entry operations. Send a
copy of the permit and narrative to the confined
space process advisor.

16.14.2 Contractor Responsibilities
All qualified contractors who perform confined space
entry operations must:
• Obtain information regarding confined space hazards
and entry operations from Chevron.
• Coordinate entry operations with Chevron.

148 | GOMBU and DWEP BU








Provide the Chevron location with a copy of the
confined space program that the contractor will follow
and maintain a copy at the work location for the
duration of the job. Program must meet or exceed the
program outlined here and must identify the entry
permit that will be used by the contractor.

• Initially monitor and then continue to monitor the
confined space in accordance with the procedures
established in Evaluating Permit-Space Conditions.
• Participate in the debriefing at the conclusion of the
entry operations to communicate any hazards
confronted during entry operations.





Provide Chevron with a copy of the completed entry
permit and include any debriefing notes. A copy should
be kept at the field’s records location for one year and a
copy sent to the GOM HES group.

• Share the required annual evaluation results with the
GOMBU Confined Space Advisor when completed.
Note: Although the regulations allow an attendant

(entry watch) to monitor more than one confined

space operation at a time when certain conditions

are met, the GOMBU allows an attendant

(entry watch) to monitor one confined space

activity at a time. It is the Chevron onsite

representative’s responsibility to communicate

with the person leading work and ensure

compliance.

Contractor Handbook | 149

16.15 Bypassing Critical Protections

Chevron Production Facilities Only



Anyone engaged in facility operation, including the
bypassing of safety devices, will be fully cognizant of the
potential for undesirable events ranging from minor upsets
to catastrophic equipment failure. There will be no deviation
from this policy.

16.15.1 Flag
Any surface or subsurface safety device that is
temporarily out of service will be flagged:
• To be in compliance with the regulations
• To be a visual reminder/alert to all personnel that a
safety device is in bypass

16.15.2 Minimum Number of Devices







You may bypass only safety devices required to allow the
startup, testing, or maintenance task to be performed.
Although it may be convenient to use a group bypass or
to bypass extra safety devices to prevent nuisance
shut-ins, use of such group devices is a clear violation of
bypassing more than the minimum.

As soon as the task is completed, place the safety
device(s) back in service and remove the flag/tag.

16.15.3 Monitor and Control








Personnel will monitor the bypassed or blocked-out
functions until the safety devices are placed back in
service. An operator will be in a position to monitor the
function of the bypassed device. If you detect an
abnormal condition, you must take corrective action
(close inlet valve, ESD platform, etc.) to prevent an
undesirable event.

150 | GOMBU and DWEP BU










16.15.4 Qualified Person
A qualified person is one who has successfully completed
a production, safety-system training program and is
familiar with the site-specific monitoring procedures of
that facility. Any person that has not received the required
training must be directly supervised by a qualified person
when engaged in installing, testing, inspecting, flagging,
bypassing, monitoring, or maintaining safety devices.

16.15.5 Training





All contract Production Safety System (PSS)-trained
operations personnel are required to complete the Flag,
Bypass, and Monitor (FBM) training modules on an
annual basis.







Newly hired PSS-trained contract operators will be
given a hard copy of the FBM process as soon as
practical and they will formally introduced to the
FBM process by field management during their first hitch
on Chevron property.

16.16 Excavation
An excavation is any man-made cut, cavity, trench, or
depression in an earth surface, formed by earth removal.
When Chevron personnel and a contractor enter a permitrequired space, each has responsibilities as outlined below.


16.16.1 Requirements

• Identify and mitigate hazards associated with
excavations before work begins.
• Complete the steps necessary to properly and safely
prepare the job site and equipment for the start
of work.

Contractor Handbook | 151







Protect personnel who enter excavations by using
support systems (e.g., shoring, bracing, sloping,
benching, and shields). Design and construct the
excavation support system using competent,
trained persons.

• Train personnel performing work for competence in the
roles for which they are responsible.
• Inspect excavation shoring or bracing systems daily and
after a rainstorm, earthquake, or other hazard-
increasing occurrence.
• Cease all work in the excavation until necessary
precautions have been taken to safeguard personnel.

16.16.2 Roles and Responsibilities
• Competent person (qualified professional)
• Registered professional engineer
• Person entering excavation
• Operator of powered excavating equipment
• Qualified gas tester





A single individual may fulfill more than one role as
long as he or she meets the training and knowledge
requirements, and is able to fully meet multiple
responsibilities.

16.16.3 Competent Person

(Qualified Professional)
• Has received additional third-party training and has
been qualified as a excavation competent person






Is capable of identifying existing and predictable
hazards in the surroundings, or working conditions
which are unsanitary, hazardous, or dangerous to
employees and has authorization to take prompt
corrective measures to eliminate them

152 | GOMBU and DWEP BU

16.16.4 Critical Components
• Pre-Job Planning and Hazard Analysis
–  The scope of the job and the hazards that can be
encountered will dictate the amount of planning that
is required.
• Collect Site Data
–  Soil analysis is important to determine appropriate
sloping, benching, and shoring.
• Utilities and Pre-Work Site Inspection
–  Before excavation, the work team leader will
thoroughly inspect the site to determine if special
safety measures must be taken.
–  Underground utilities such as sewers, telephone, fuel,
electric, water lines, or any other underground
installations that may be encountered during
excavation work shall be located and marked, and
proper notifications made, before excavation with
powered equipment begins.






Permit to Work – A Permit to Work and Excavation
Permit are required for any excavation work and before
breaking the surface. Additional permits may also be
required depending on the nature of the work (i.e., hot
work, confined space entry, electrical).

• Inspections – A competent person will conduct
inspections before the start of each shift or when
conditions change.

16.16.5 Modes of Failure
• All excavations, no matter what depth, may be
hazardous. Personnel involved must recognize modes
of failure and understand Soil Type A (most stable) -B-C.

Contractor Handbook | 153

• Excavations greater than or equal to 5 feet deep
are particularly hazardous and must be shored unless:
–  The face is cut back to a safe slope and the
material in the face will remain stable under
anticipated conditions of work and weather; or
–  Shoring is impracticable or unreasonable, and a civil
engineer or other qualified professional has certified
that adequate safety precautions have been taken; or
–  No one will be entering the excavation.





Excavations shallower than 5 feet have been known to
collapse. Provide protection of personnel in excavations
lower than 5 feet where hazardous ground movement
may be expected.

• Control exposure to vehicular traffic.
• Erect barriers to prevent unauthorized people from
entering the excavation area or accidental falls into the
excavation.
• Locate the exact position of the utility precisely by hand
digging or probing with a blunt object.
• A civil engineer or other qualified professional must
review excavation in close proximity to buildings, roads,
retaining walls, and other structures before the
excavation is started to determine the appropriate
controls to address the risk of cave-in.
• Control surface water and cutoff drains.

16.16.6 Evacuation Permits





The Chevron GOM Excavation (Specialized) Permit will
be completed for all excavations and trenches where
equipment is used and soil is removed to a depth
greater than 12 inches.

• All excavations where employees are to enter are to be
evaluated as a confined space.

154 | GOMBU and DWEP BU

Note: The Competent Person (CP) listed at the bottom of

the form can be either a Chevron CP or a

contractor CP.



16.16.7 Leadership Expectations

• Implement this standard at all onshore facilities.
• Ensure contractors involved in excavation understand
and follow this standard when they are under Chevron’s
operational control.

Contractor Handbook | 155

17.0 Crane and Rigging Safety
17.0 Lifting and Rigging Safety
The following requirements apply to
all contract companies operating
cranes under Chevron’s operational
control. Some sections contain
information specific to cranes on
Chevron facilities. These requirements
do not apply to contractor cranes not
on Chevron facilities.
Note: The use of field-modified or non-certified lifting

and hoisting equipment is prohibited. Field-

modified or non-certified lifting equipment

must be removed from service immediately and

reported to your supervisor. Speak with your

supervisor if you have any questions.

17.1 Training
All contract employees who perform rigging or operate
cranes on Chevron property must have current
documentation verifying successful completion of Qualified
Crane Operator/Rigger training in accordance with API RP
2D, latest edition.

17.2 Heavy Lifts/Hazardous Lift
Evaluate all lift paths to minimize exposure where possible.
Review the load chart before the lift to determine if heavy
lift inspection is required.
All sling tags will reference the rated capacity of a
Horizontal sling angle minimum of 45 degrees.
Note: Never use a horizontal sling angle less than

45 degrees. The optimum angle for rigging

practices is 45 to 75 degrees.

156 | GOMBU and DWEP BU












Hazardous lift – At a minimum,
hazardous lifts are defined as any
lifts made over unprotected
pressurized equipment where the
consequence of a dropped load
could result in significant damage
or injury to personnel. Additional
consideration should be given to
nonroutine lifts of hazardous materials (acids,
flammable liquids, pressurized equipment, etc.).







Heavy lift – A nonroutine lift (i.e., drilling, workover,
construction, wireline, etc.) is equal to or greater
than 75% of the rated capacity per the load chart, at
the anticipated minimum boom angle/maximum radius
of the lift, at either a dynamic or static condition.

17.3 Weather
All contractors operating cranes
under Chevron’s operational control
are required to define environmental
operating parameters for crane
operation. These parameters will
reflect the limitations of the crane(s)
used and the requirements of the
contract company’s crane program.
For Chevron and contract company cranes on Chevron
facilities, the following environmental parameters have been
established:

• Dynamic load charts are designed using six-foot to eight-









foot seas or 24-mph wind speeds. If the wind and sea
conditions exceed these values, the Chevron person in
charge should consider consulting with the manufacturer
for possible temporary de-rating of the crane’s dynamic
load capacity. Vessel operators may have more restrictive
weather guidelines for their vessels, which may take into
account current strength, as well as wind and sea
conditions.
Contractor Handbook | 157

Crane operations must be stopped under these conditions:
Weather and Sea Conditions That Stop Crane Operations
Conditions

Operations Stopped

Seas meet or exceed 12 feet

All dynamic crane
operations

Winds meet or exceed
35 mph

All crane operations, static
and dynamic

Lightning is in the vicinity

All crane operations, static
and dynamic

17.4 Crane Repairs and Alterations
• Take the crane out of service or restrict its operations
to eliminate the unsafe condition if adjustments or repairs
to the crane are necessary or any deficiencies that impair
safe operation are known.

• Perform repairs to critical components in accordance with
API RP 2D.

• A qualified crane inspector must approve/authorize a
crane taken out of service for repair of critical
components before it can go back into service.

• If a crane is taken out of service, place an Out of Service






sign over the primary controls (should be isolated using
local Isolation of Hazardous Energy procedures). If a
crane has been out of service for more than 12 months,
perform an annual inspection before the crane is placed
back into service.

158 | GOMBU Shelf and DWEP BU Deepwater

17.5 Sling Certification
Do not use the sling if the identification tag is missing.
Render the sling unusable and dispose of it if a replacement
tag cannot be obtained.
All wire rope slings and nylon slings must contain
identification tags consistent with the following required
information:

• Diameter and length
• Pertinent working load limits
• Name of manufacturer
• Proof of test certification number and date
• A valid color code identification to indicate that an annual
sling inspection has been conducted. (see page 161 Color
Code table)
Note: Do not use chain slings for lifting, except when

used with overhead hoists during maintenance

operations. The Chevron GOM Crane team must

approve exceptions for special lift operations.

17.6 Sling Inspections
17.6.1 Pre-Use Inspection









A qualified rigger must visually inspect all slings before
each lift operation. This inspection should include visual
examination for kinking, crushing, bird-caging, or any
other damage to the wire rope or end attachments. For
synthetic web slings, inspection should include holes,
tears, cuts, embedded particles, and broken or worn
stitching. Additionally, the qualified rigger must verify that
all slings have proper certification tags.

17.6.2 Annual Inspection
The annual inspection of third-party slings is the
responsibility of the vendors providing the slings. Render
inoperable all slings taken out of service, and properly
dispose of them.

17.6.3 Identification Codes
A color and/or shape code easily identifies a component
or item of rigging gear with the current inspection status.
Each SBU will use a minimum of three colors and/or
shapes, which are conspicuously displayed at the
workplaces. Do not apply the color and/or shape code
identification directly to the load-bearing part of a

160 | GOMBU and DWEP BU

synthetic sling; place it on the identification tag so that it
does not obscure any critical data.
Annual Sling Inspection and Color Identification







For wire rope slings, during the annual inspection, paint
all sling sleeves in acceptable condition (crimps only)
with the appropriate color code for that year. Refer to
the Color Code table.

Note: When new Chevron-owned slings are received on

a location, notify Smart Support with the new

slings’ data (platform, sling type, certification

number and installation date, vertical

capacity, wire rope diameter and length).

• Nylon (web) slings will be changed out on an annual





basis (12 months from “born on” date). Slings will be
marked with “born on” date, the sling’s certification
number, and the color code for the year that the sling
is purchased.

• All qualified riggers are trained (as per API 2D) to
perform the annual sling and cargo-carrying unit
(CCU) inspections.
• Slings that fail the annual inspection are removed from
service and are destroyed and discarded (rendered
unusable).

• All qualified crane operators and riggers are trained to
conduct pre-use inspections to identify damaged or
defective rigging as per API standards.

• All crane operators, riggers, and associated individuals
that are using slings can remove any questionable slings
from service.

• All crane operators, riggers, and shorebase personnel
monitor slings during their pre-use inspection to ensure
that each sling has the current color code.


17.6.4 Sling Storage








Do not store slings on the deck or ground. Store and
maintain slings in a well-ventilated building or shed to
minimize corrosion. If space limitations require storing
slings along the side of the platform, secure them to
prevent abrasion from rubbing. Store nylon slings in a
way that provides UV protection.







Never use the guardrail or handrail as an anchor point for
lifting or supporting a load (i.e., sling storage), or as an
anchor point for fall protection gear. Light lifesaving
devices, such as buoys and floats, as well as ESD stations,
may be mounted to guardrails.

17.7 Rigging Hardware – Maintenance and
Inspection



17.7.1 Shackles
Before making a lift, visually inspect shackles used in
lifting:
• Check the pin for straightness and complete seating.
162 | GOMBU and DWEP BU

• Look for cracks, deformities, and evidence of heat
damage or alterations.
• Check the distance between eyes for signs of
opening up.
• Check eyes for roundness and twisting.





Discard unsuitable shackles. Also, discard those shackles
that do not clearly show the rated capacity or that are
worn by more than 10% of the original diameter in the
crown or pin.







As a standard practice, each shackle in a bridle hitch
should be one size larger than the size of the wire rope
(sling) used. As shown in the following table, the pin size is
one size larger than the shackle size (e.g., a 5/8-in.
shackle will have a ¾-in. pin diameter).

17.7.2 Eyebolts






Carefully inspect eyebolts before each lift. Check them
for wear or damage, cracks, bending, elongation or
other deformities, and damaged or dirty threads; also
check the receiving holes. Look for evidence of
grinding, cutting, machining, or other alterations.

• Remove from service and discard any unsuitable eye
bolts exhibiting any of the above conditions.

Contractor Handbook | 163

17.7.3 Hooks
• Visually inspect hooks for cracks, corrosion, bending,
twisting, wear, general damage, and missing or
corroded pins and bolts.
• Replace hooks that were opened more than 15% of their
nominal throat opening or twisted more than 10 degrees
from the plane of the unbent hook.
• Make sure that all hooks, except sorting and choker
hooks, have functioning latches.
• Verify that there is no paint on the hook.

17.7.4 Pad Eyes






Flame-cut pad eyes are prohibited in operations under
Chevron’s operational control, unless followed by
machining away at least 1/8 inch from the material after
burning. All pad eyes must be of an engineered design
suitable for the intended load and service.







Visually inspect pad eyes before making a lift by
checking them for evidence of bending, crushing,
bulges, burrs, or other deformities. They should also be
inspected for cracks, excessive rust, wrinkled paint, and
indications that the pad eye has been modified.






Make sure that all pad eyes are smooth in the direction
of the lift to prevent point-load stress failures during lift
operations. Replace the pad eyes if they exhibit any of
these conditions.






Drill, ream, punch, or cut holes in pad eyes fabricated in
the shop or fabrication yard with a mechanically guided
torch at right angles to the surface of the metal to
ensure a smooth surface in the direction of the lift.

• Punching must not be used on a plate more than
1/2 inch thick; other methods may be used, if they are
approved by Facilities Engineering personnel.

164 | GOMBU and DWEP BU







If the pad eye design includes addition of cheek plates,
all holes must be fabricated after the cheek plates are
completely welded in place. Holes must be cleanly cut
and must not have torn or ragged edges. All holes must
be made before surface preparation and painting.

Field construction of pad eyes is discouraged. However, if
this becomes necessary, the pad eyes must:
• Be properly designed and approved by a qualified
engineer.
• Be properly installed by a qualified/certified welder.
• Have smooth bearing surfaces in the direction of the
lift ground.
• Pass inspection by the appropriate nondestructive
testing technique (ultrasonic, x-ray, or magnetic
particle examination).

17.8 Delivering and/or Handling Cargo at
Chevron Facilities



To assure safe operations at our facilities, the following
guidelines for contractors operating cranes or delivering
material and cargo to Chevron facilities will be enforced.

• Chevron personnel will examine cargo and refuse to
attach or lift any load they judge to be unsafe.

• The contractor will be asked to correct situations when





their company is involved in improper crane operations or
rigging practices. Improperly prepared cargo may be
returned to the contracting company at the contracting
company’s expense.

• All lifting equipment and containers must be in good
condition and capable of handling intended loads.

• Do not use chains as slings.
• Do not cut or weld lifting equipment.

Contractor Handbook | 165

• Use bolt-type safety shackles (with cotter pin or keeper





ring) for permanent rigging. Only shackles with the
manufacturer’s name or logo and the load-bearing
capacity embossed in raised letters on the shackle
body are permitted.

• Do not alter lifting equipment, such as shackles, hooks, or
pad eyes, by welding or cutting.

• Use only stainless and forged alloy shackles.
• Verify that all hooks, including choker hooks and sorting
hooks, have functional safety latches and that the latch is
completely closed when in use.

• Use steel thimbles on all wire rope sling eyes.
• Permanently mark all skid-mounted equipment (e.g.,
welding machines, air compressors, pumps) that exceeds
1,000 pounds capacity with the maximum weight of

the equipment.

• Permanently mark the maximum design “gross” weight





capacity and “net” (empty) weight on all cargo containers,
such as trash baskets, tool baskets, grocery boxes, drum
racks, gas cylinder racks, cutting boxes, sensitive material
bins, hazardous material bins, and portable racks.

• Upon request, the operator must be able to provide
documentation certifying that the cargo containers and
skids are of an engineered design capable of withstanding
the stated maximum loads.

• Configure or pre-rig for a one-point hookup all cargo
(excluding tubular containers) delivered to shorebase
locations for shipment offshore.

• Attach slings to loads with shackles, rather than hooks,
except in these circumstances:
–  A stinger is attached directly to a load for a one point lift.
–  Adjustable choker slings are used.
–  Loading or unloading casing at drilling or workover rigs.

166 | GOMBU and DWEP BU

Note: This shackle requirement does not apply to

shorebase or land locations.



• Only use synthetic web slings and adjustable sliding
choker slings for choker configurations.

• Use bolt-type safety shackles (with cotter pin or keeper
ring) for permanent rigging.

• Do not shorten or alter a sling by knotting, clipping, or
other means.

• Annually inspect and verify that the slings have
certification tags (in accordance with API RP 2D).

• Do not externally cover slings with any material that
would prevent visual inspection. For example, do not cover
wire rope slings with a rubber hose.

• Use a drum rack to move drums to or from a vessel





offshore. On platform lifts (static lifts), move drums with
synthetic web slings using choker hitches and move single
metal drums with a locking drum clamp. Do not use cargo
nets to move drums.

• Place loose items, such as drums, sacks, valves, and







buckets in appropriate containers (cargo baskets) to make
loading and offloading more safe and efficient at offshore
facilities. Cargo placed in cargo baskets should not exceed
the top of the basket and should not protrude over or
through the sides of the basket. If the cargo does not
safely fit in the basket, lift it as a separate or single load.

• Do not attach or detach loads on their vehicles for the
purpose of crane lifts while on Chevron property.

• Truck drivers are required to use personal protective
equipment in accordance with Chevron PPE requirements.

• The freight company must furnish fastening equipment
for securing cargo on motor vehicles on Chevron
property.

Contractor Handbook | 167

• Vessel captains and crane operators are responsible for





determining the safety of cargo transfers between marine
vessels and Chevron facilities. Either party may refuse to
make a transfer for safety reasons. Marine companies will
not be penalized for refusal to make such a transfer.

• The captain of the vessel must ensure that cargo is






properly positioned and secured on the vessel before
leaving our facilities. The marine company must furnish
fastening equipment for securing cargo on marine
vessels. The captain of the vessel has final authority to
refuse to transport any cargo not properly secured.

Contractors should direct any questions about these
guidelines to the appropriate Transportation or Operations
supervisor.

17.9 Tag Lines
All lifts being moved to or from a boat will have a tag line.

• The tag line should be made from ¼-in. hemp rope, and
should extend between 15 to 20 feet from the load. The
line will be attached to the load.

• For large loads, two tag lines are recommended with one
placed at each end of the load.

• When using a tag line to direct a load into place, be aware





that the load can swing into other objects when you apply
too much force in the wrong direction at the wrong time.
Pull easily until the load turns, and then direct it into place
by using only enough force to get it there.

• Special lifting configurations may require longer tag lines.
• Tag lines will be free of any knots, splices, or loops.
• There are additional risks to be aware of when using tag
lines, which include, but are not limited to:
–  The possibility of injuries from falling objects as a result
of personnel handling cargo working in closer proximity
to loads.

168 | GOMBU and DWEP BU

–  There are potential injuries resulting from personnel
handling cargo:
•  Being dragged if a heavy load rotates in an
uncontrolled manner.
•  The tag line could be fouled in limbs or clothing.
–  There are potential injuries resulting from tag lines
secured to adjacent fixed structures, parting due to a
heavy load, and snapping in an uncontrolled manner.
When using tag lines, observe the following:

• Tag lines are an aid in positioning the load.
• Keep all sections of the line, including slack, in front of
the body, between the person handling the tag line and
the load.

• Hold tag lines where they can be quickly released. Do not
wrap tag lines around the hands, wrists, or any other part
of the body.

• When wearing gloves, take care that the tag line does not
foul the glove.

• Do not secure or attach tag lines to any structure,
equipment, handrails, stanchions, cleats, or any other
items.

• Where tag lines have already been installed on the load,
consider using a boathook to retrieve the tag line to avoid
being close to or under the load.

17.10 Overhead Hoists
• Any Chevron or contractor-employed person, company, or
contractor who operates an overhead hoist under
Chevron’s operational control must be a qualified rigger.

• Maintain a file at each field location for all overhead hoists






installed in that field. This file contains copies of the

pre-use inspection forms, annual inspection forms, and all
maintenance and repair documentation. These records
must be retained for a period of four years for Chevron
facilities.
Contractor Handbook | 169

• A qualified rigger must perform and document a pre-use





inspection on the Overhead Hoist Pre-Use Inspection
Form before operating Chevron-owned overhead hoists.
Pre-use inspections are required once per day when a
hoist is operated.

17.11.2 Contract Crane Operator Checklist







The Chevron Contractor Crane Operator Checklist is
administered by a Chevron-qualified observer and
witnessed by the onsite contractor supervisor, if
available. Upon successful completion of this checklist, the
contract crane operator is considered a Class A crane
operator in accordance with Chevron’s crane program.








Contract crane operators who do not successfully
complete the checklist are given one opportunity to
review the checklist’s content and take the test again. If
a contract crane operator is unable to complete the
checklist successfully after the second attempt, that
individual must wait for 30 days before retaking the test.







A copy of the operator’s completed checklist must be
maintained in the field crane files and sent to the GOM
crane coordinators. A list of Class A contract crane
operators is available for review on the Employee
Resource and Training Center (ERTC) website.









The qualified observer may conduct re-evaluations of
each contract operator and upgrade or downgrade the
classification of each operator. Additionally, the qualified
observer should give special consideration to
re-evaluating crane operators based on their experience
with different types of cranes (joystick controls, standard
controls, etc.).

17.11.3 Weight Indicators







If weight indicators are installed, they must be maintained
in operational condition, or they must be removed. All
components of the weight indicator (e.g., hoses, cells)
must be removed from the crane when the indicator
gauge is removed. If needed, weight indicators can be
temporarily installed for periods of high crane usage.

Cargo weight over 1,000 pounds must be recorded on the
shipping manifest and marked legibly on the cargo before
shipping. If the cargo weight is unknown and a weight
172 | GOMBU and DWEP BU






indicator is not installed, the cargo weight must be
determined by using a dynamometer or some other
means. Dynamometers must not be used under dynamic
conditions.









When a dynamometer is used to determine weight, the
dynamometer serial number and load weight must be
recorded on the shipping manifest. For loads sent from
field locations to the shorebase locations, the load
weights must be verified with the shorebase cranes. Any
significant deviations from the shipping manifest must be
communicated to the Operations supervisor.

The calibration frequency for dynamometers should
follow the manufacturer’s recommendations (typically
annually).

17.11.4 Unattended Control Stations
Before leaving the control station unattended for a
prolonged period, the crane operator must follow
these steps:
1. Land any attached load.
2. Disengage the master clutch, where applicable.
3. Set all locking devices.
4. Put controls in the off or neutral position.
5. Stop the prime mover.
6. Assure that no component of the crane will interfere
with normal helicopter flight operations.






Some wireline operations require that the crane be left
attached to the suspended lubricator (lubricator stabbed
and resting on the tree connection). This is an acceptable
practice as long as the procedures listed above are
followed.

Contractor Handbook | 173

17.11.5 Bypass of Safety Devices







The bypass of safety devices during pre-use inspections is
acceptable. However, bypassing the boom kick-out, anti-
two-blocking, or other limiting device on a crane for
reasons other than inspections will not be allowed, unless
authorized by the Operations supervisor and properly
tagged and documented.








A tag listing the date and name of the authorizing person
must be attached to the crane whenever a bypass is
authorized. This information must also be documented in
the platform logbook. The tag must be in plain view of the
crane operator. In addition, a written JSA is required
before performing the lift.

17.12 Communication
• Discuss with the lift team (the qualified crane operator,
qualified rigger(s), and vessel captain) the
circumstances of the lift before making the lift.
• The qualified crane operator must obtain all pertinent
information contained on the shipping manifest before
cargo transfer begins.







The qualified crane operator is responsible for the safe
operation of the crane and has the authority to refuse
to make any lift. After consultation with the crane
operator, the vessel captain determines if the cargo can
be transferred to or from the vessel safely. Either party
may refuse to make a transfer for safety reasons.

17.12.1 Radio Communication







Lift team members must use radios and hand signals to
communicate during the lift operation. If radio
communication is not available for key members of the
team, a written JSA is required. The team must have the
written or verbal approval of the Operations supervisor
(or designee) before conducting the lift operation.

174 | GOMBU and DWEP BU

Note: The team must verify that the type of radio used
is suitable for the work environment. The use
of radios, as well as other portable electronic
devices, must be done in accordance with the
Chevron Hot Work Guidelines.
Refer to the Non-Welding Hot Work Risk Matrix
for clarification on specific requirements.

17.12.2 Pre-Lift Checklist and JSA
When feasible, the lift team should prepare a written JSA
before beginning a lift operation. In certain cases, a
written JSA is required (e.g., heavy lifts and lifts without
radios).
Use a Crane Pre-Lift Checklist or the Crane Operations
JSA (aka Yellow Card) in lift operations where a written
JSA may not be feasible. For example, use the checklist
yellow card in cases such as dynamic lifts, where part of
the lift team is on a platform and the other part of the
team is on a boat.
The checklist/crane operations JSA are tools containing
a bulleted list of key safety checkpoints for crane
operation. Before beginning the lift operation, all
members of the lift team must have access to a copy of
this checklist and verbally (by radio) review each bullet to
ensure all safety requirements have been met.

17.12.3 Lift Team Responsibilities
The lift team consists of all key personnel involved in the
planning and execution of a lift operation. The team
typically includes a qualified crane operator, one or more
qualified riggers, and the vessel captain. Depending on
the scope of the lift operation, the lift team may also
include the facilities engineer, facilities representative,
drilling representative, workover representative, and
production operator.

Contractor Handbook | 175

Key responsibilities of the lift team are outlined in the
following list. The specific responsibilities of key lift team
members are provided in later sections of this handbook.
17.12.3.1 Pre-Operation
The lift team has these responsibilities before beginning
the operation:
• Conduct a pre-lift meeting to review the scope of work
and the execution plan.
• Review the Crane Pre-Lift Checklist with all members of
the lift team.
• Prepare a written JSA for all heavy lifts and nonroutine
lifts.
• Evaluate lift operations to determine if additional
qualified riggers are needed to assist in loading or
offloading operations.
• Ensure that a clear method of communication is
established.





Assess site conditions to ensure that the lift operation
can be conducted safely, taking care to include sea
state, currents, wind speed and direction, weather, size
of the vessel, position of cargo, and adequate lighting.






Review the lift path and the weight of the loads to
determine if specific simultaneous operations
procedures are required to protect production
equipment from falling loads.

17.12.3.2 During Operation
The lift team has these responsibilities during the
operation:
• Maintain constant communication between all lift team
members.





Stop work and conduct another pre-lift meeting if site
conditions change or if the lift operations change from
the original plan. Complete a Crane Pre-Lift Checklist
and JSA, as required, before continuing with the lift.

176 | GOMBU and DWEP BU

17.12.4 Crane Operator Responsibilities
All Chevron crane operators will be designated as Class
A, B, or C operators. A qualified crane operator
must be requalified every four years, at a minimum. A
qualified crane operator must also meet the requirements
of a qualified rigger.
17.12.4.1 Pre-Operation
Before the operation, the crane operator has these
responsibilities:

• Participate in the pre-lift meeting as discussed in the
17.12.3 Lift Team Responsibilities.

• Conduct a pre-use inspection before beginning crane
operations.

• Ensure that heavy lift inspections were completed
within 21 days of making a heavy lift.

• Verify that all personnel involved in executing the lift
operation, such as the crane operator and rigger, have
the proper qualifications.

• Designate a qualified rigger as a signal person to relay
signals any time the qualified crane operator is unable
to see a load.

• Ensure that only qualified riggers and essential
personnel are allowed in the work area during lift
operations.

• Verify load weights by load markings and shipping
manifest documentation.

• Verify that the appropriate load-rating chart is in place
and that the rigging is properly configured to
accommodate the planned loads.

• Ensure that the proper rigging equipment is selected
and inspected by a qualified rigger before the lift
takes place.

Contractor Handbook | 177

17.12.4.2 During Operation
During the operation, the crane operator has these
responsibilities:
• Assume ultimate responsibility for safe operation of
the crane.
• Do not start machine movement unless the load or
signal person is within range of vision. Appropriate
signals (audible or visual) must be given.
• Respond to signals only from the appointed signal
person and respond to emergency stop signals from
anyone at any time.
• Make sure that you do not exceed the crane capacity,
shown in the load chart, during crane operations.
• Be aware of helicopter traffic, and follow procedures
outlined in section 17.11.4 Unattended Control Stations.
• Ensure there is sufficient lighting for safe operation
when cranes are operated at night. The load and
landing area must be illuminated.
• Wear proper work clothes and personal protective
equipment in accordance with Chevron PPE
requirements.
• Stop any lift operation that is deemed unsafe (exercise
Stop-Work Authority).
• Re-evaluate crane operations during bad weather or
when the ability to communicate with the signal person
is impaired.
17.12.4.3 Post-Operation
After the operation, the crane operator has these
responsibilities:
• Ensure that the crane is properly secured and controls
are turned off or in the neutral (for hydraulic cranes)
position before leaving the crane.


178 | GOMBU and DWEP BU

• Do not leave an unattended crane with a load in the air.
Always lower the load to the deck before leaving the
crane. (See section 17.11.4 Unattended Control Stations
for the exceptions to this guideline that occur during
wireline operations.)

17.12.5 Rigger Responsibilities
All personnel, Chevron or contract, participating in rigging
operations on Chevron facilities must be qualified riggers,
in accordance with API RP 2D. The riggers must provide
documentation indicating that they have successfully
completed a rigger training course that meets the
requirements of API RP 2D. Rigging operations include, at
a minimum, attaching and detaching lifting equipment to
loads and providing signals to crane operators.
Requalification must be conducted at least every
four years.
Communication among lift team members is one of the
team’s most important responsibilities.
17.12.5.1 Pre-Operation
Before the operation, the rigger has these responsibilities:

• Participate in the pre-lift meeting as discussed in
section 17.12.3. Lift Team Responsibilities.

• Ensure that only qualified riggers and essential
personnel are allowed in the work area during lift
operations.

• Verify load weights by load markings and shipping
manifest documentation.

• Select the proper rigging equipment and cargo
container for the lift.

• Make sure that the safe working loads of the equipment
and tackle are never exceeded.

• Inspect all hardware, equipment, tackle, and slings
before use. Destroy or render unusable any defective
components.
Contractor Handbook | 179






Verify that all slings have proper certification tags. If
the identification tag is missing, do not use the sling. If a
replacement tag cannot be obtained, notify the Chevron
representative.

• Inspect all loads or cargo containers, including
permanent slings or tackle. Evaluate load stability and
potential for spill or release of fluids.
• Ensure that a designated signal person is identified and
that the team agrees upon a communication method.
17.12.5.2 During Operation
During the operation, the rigger has these responsibilities:
• Assume responsibility for the safety of all personnel
around the crane and crane operating area, including
the rigger’s personal safety.
• Act as a signal person, when designated, during the lift
operation.
• Look for potentially unsafe situations and warn the
crane operator and others in the crane operations and
crane operating area.





Do not stand between the load and another stationary
object or boat railing (pinch zone). The rigger should be
facing the crane at a safe distance and never stand
directly beneath the load.

• Wear proper work clothes and personal protective
equipment in accordance with Chevron PPE
requirements.
• Stop any lift operation deemed as unsafe (exercise
Stop-Work Authority).

180 | GOMBU and DWEP BU

17.12.5.3 Post-Operation
After the operation, the rigger has these responsibilities:

• Properly secure loads on vessels, using the equipment
furnished by the vessel company.

• Properly store and maintain rigging equipment and
tackle.

17.12.6 Vessel Captain Responsibilities
Vessel stability is the primary concern when loading a
vessel. The cargo must be positioned on the deck of the
vessel to facilitate rigging during offloading operations.
The vessel captain is always a key member of the lift team
for any lift operations that involve a boat or marine
vessel. In addition to the lift team’s responsibilities
previously mentioned, the vessel captain has the following
responsibilities:

• Participate in the pre-lift meeting, by radio.
• Participate, by radio, in preparation of written JSAs,
as required.

• Ensure the vessel’s stability for all cargo placed upon
its deck.

• Verify that the proper fastening equipment for securing
the cargo is onboard, in good working condition, and
furnished by the vessel company.

• Make sure that the cargo is properly positioned and
secured before leaving the dock or offshore facility.

• Ensure that all deckhands, contractors, and Chevron
personnel participating in rigging operations on the
vessel wear proper work clothes and personal
protective equipment in accordance with Chevron PPE
requirements.

Contractor Handbook | 181






Verify that all tag lines attached to cargo are properly
positioned, or remove the lines to prevent trip hazards
and to prevent them from being trapped beneath other
cargo.

• Stop any lift operation to or from the vessel that is
deemed unsafe (exercise Stop-Work Authority).
• Make sure that the vessel is maneuvered away from the
load during the lift operation.
• Maintain communication with the lift team during lift
operations via hand signals and radio.
• Ensure that all cargo loaded onto the vessel is properly
documented on the shipping manifest, with the weights
recorded.
17.12.6.1 Pre-Use Inspection






The pre-use inspection must be performed and
documented before the crane is used. The inspection is
typically performed on a daily basis. An inspection is also
performed during extended operations whenever the
qualified crane operator deems it necessary.








This documentation should be maintained in the vicinity of
the crane. A qualified crane operator performs this
inspection. The inspection applies to all cranes, regardless
of usage category. If the qualified crane operator
changes, a new pre-use inspection should be performed
and documented by the new operator.

The pre-use inspection also includes rigging gear, such as:
• Slings
• Cargo baskets
• Cargo containers
• Cargo nets
• Personnel baskets
• Drum racks
• Trash baskets
182 | GOMBU and DWEP BU

• Tool boxes
• Grocery boxes
• Gas cylinder racks
• Sensitive material bins
• Cutting boxes/bins
• Hazard material bins
• Portable tanks
As a minimum requirement, each crane (excluding
out-of-service cranes) must be operated once a month.
This includes the operation of all crane functions and the
testing of each safety device (one completed pre-use
inspection). The crane operation requirement helps
extend component life and, because of regular lubrication,
helps prevent sticking of other components.

17.12.7 Alternate Lifting Devices
Several lift assist devices (e.g., stiff legs, hydraulic masts,
air-tuggers) currently fall outside the scope of API RP 2D.
All personnel involved in installation, operation, and
maintenance of these devices on Chevron properties
must be qualified riggers, and they must know the
manufacturer’s recommendations, guidelines, and
procedures.
All personnel involved in installation, operation, and
maintenance of knuckle boom cranes on Chevron
properties must be qualified crane operators, and they
must know the manufacturer’s recommendations,
guidelines, and procedures.
Visually inspect the following equipment before use. In
addition, prepare a written JSA with consideration given
to the following items:

• Weight capacity limitations
• Cargo weights
• Stability and anchor points
Contractor Handbook | 183

• Device placement
• Weather and site conditions
• Operator qualifications
• Wire rope and loose gear inspection
• Containment and spill potential
• Safety devices
• Lift team communication
• Lift path

17.12.8 ISO/Shipping Containers







ISO containers are manufactured according to
specifications from the International Standards
Organization (ISO) and are suitable for multiple
transportation methods such as truck, rail, or ship
(intermodal). The ISO shipping container design has
limitations that include:

• Dynamic load factor of 2.0
• No side impact factor
• Applicable for sheltered water loading and unloading
• Requires specific handling equipment such as:
–  Vertical lift appliance when lifted from the top
–  Lifting lugs and spreader bar when lifted from
the bottom
–  Fork lift





To compensate for design limitations, the original rated
cargo capacity of the ISO shipping container is reduced by
33% when lifted or moved in offshore application on
Chevron facilities or in Chevron service.

Original rated cargo capacity = Gross container weight –
Container tare weight.

184 | GOMBU and DWEP BU

ISO shipping containers can be loaded to the original
rated cargo capacity in offshore operations when in a
static condition (i.e., not being lifted or moved).
Future use of these containers is being reviewed, and
additional guidance will be issued when that review is
complete.
Inspection
Inspect ISO shipping containers for mechanical damage
and corrosion before lifting, moving, or handling. Give
particular attention to corner fittings that may have
damage from use of nonstandard lifting lugs or lifting
devices. No container may be lifted or moved if damage is
found until the effect of the damage on the integrity of
the container is assessed by a qualified engineer.
