3) improper labeling of fixed CO2 system protecting the e-gen space, and
4) the fire damper located on emergency generator room bulkhead was unable to properly close. Issued def #14.
DRILLS:
Fire Drill - Initiated within the Smoking Tea Room via actuation of a heat detector. Crewmember selected to find the simulated
fire had a firm grasp of reporting call points & use of portable firefighting equipment. General Alarm sounded and master took
appropriate actions. Crew immediately set fire watches & cooled boundaries, shut down ventilation, & simulated securing
electrical power. Witnessed dress-out of Fire Team 1 but due to rapid response by the primary team and boundary procedures,
the fire was called 'out' upon arrival of Fire Team 1. Flash hoods were not properly donned and discussed the same with the
team/crew. Observed good management/accountability of fire team members during the transit from the fwd Fire Locker to the
accommodations. Tested highest and lowest fire hoses; all sat.
Abandon ship drill - Witnessed satisfactory abandon ship drill with stbd lifeboats simulated to be out of service. Conducted drill
on the port side (combination of primary & alternate stations). Crews were mustered in 4 separate areas to reduce
confusion/congestion. Full muster was obtained but was delayed due to 2 contractors being counted as crew (contractors were
supposed to disembark for the drill). Boats were not loaded for the drill. To test the crew's ability to obtain proper personnel
accountability, one crewman was asked to stay in his stateroom during the mustering portion of the drill. Lifeboat coxswain &
OIM quickly realized a crewmember was missing, ordered a search, & found him in stateroom. Immersion suits were donned by
the crew separately after the drill on the Mess Deck; required some direction in proper donning. Drill was performed
satisfactorily.

Issued 14 deficiencies: 4 corrected on the spot and 10 remain outstanding. 7 of the deficiencies were required to be corrected
prior to departure to satisfaction of Class and/or CG. Examination complete.

Re:

Request for Determination that Maritime Advisors are not Members of the
Regular Complement of an Outer Continental Shelf Unit

Dear Commander Cintron:
On behalf of Shell Exploration & Production Company and Shell Gulf of Mexico, Inc.
(collectively “Shell”), we request an exemption from the employment restrictions pertaining to units
engaged in Outer Continental Shelf (“OCS”) activities on the basis that certain individuals are not
members of the “regular complement of the crew.” 33 C.F.R. § 141.15. Specifically, Shell requests that
the Coast Guard exempt four (4) foreign national Maritime Mobile Offshore Drilling Unit (“MODU”)
Advisors (“Maritime MODU Advisors”) from the requirement to employ U.S. citizens or resident aliens
aboard a vessel engaged in OCS activities. The following information is provided in support of this
request.
Background
Shell intends to conduct exploration drilling activities in 2015 on federally-managed OCS oil and
gas leases located a minimum of 64 miles from the coastline in the Chukchi Sea. These operations will
take place pursuant to Shell’s Chukchi Sea Revised Exploration Plan which is scheduled to occur during
the short open-water season, defined historically as approximately July through November.
Shell has, in light of its experience operating on the Alaska OCS, identified a need to employ
individuals with unique job skills during this period. Shell completed a review of its 2012 Chukchi and
Beaufort Seas OCS exploration drilling operations and concluded, among other things, that there was a
need to strengthen its maritime assurance controls for future operations. As part of this review, Shell
identified a need to more closely monitor its Alaskan contractor operations to ensure that its contractors
meet or exceed Shell standards and to ensure all operations are conducted in a safe and environmentally
compliant manner.
Consequently, a new Maritime Assurance team was developed and charged with overseeing and
executing maritime assurance tasks on board two MODUs, the Noble Discoverer and Polar Pioneer (the
1

Commander Hector L. Cintron
February 17, 2015

“Vessels”), which are owned and operated by Shell contractors. The goal of this team and its marine
experts is to ensure that all maritime aspects of Shell’s drilling operation will be conducted in accordance
with applicable regulatory requirements, industry best practices, and Shell’s internal maritime standards.
These individuals will help to ensure that the company executes its drilling activities exceptionally well in
2015.
The Maritime Assurance team tasked with overseeing the Vessels consists of four Maritime
MODU Advisors that will work in rotating shifts aboard the Vessels to oversee operations on behalf of
Shell. The Maritime MODU Advisors are Shell employees and will be Shell’s onboard marine assurance
representatives. These are the four (4) foreign nationals for which we request the exemption from the
OCS employment restrictions
This type of Maritime MODU Advisor is not typically employed by Shell on drillships during
normal drilling operations occurring elsewhere on the U.S. OCS. However, as noted above and as
explained in more detail below, Shell has determined that the employment of these Maritime MODU
Advisors is critical to enhancing Shell’s ability to provide the necessary oversight over some of its key
contractors in order to operate safely in the Chukchi Sea this season.
Legal Requirements and Policy Guidance
An employer of personnel on any unit engaged in OCS activities must employ, as members of the
“regular complement of the unit,” only citizens of the United States or resident aliens. 33 C.F.R. §
141.15. Personnel considered part of the “regular complement of the unit” are those necessary for the
routine functioning of the unit, including marine officers and crew, industrial personnel and general
maintenance personnel. Individuals not considered part of the “regular complement of the unit” are
specialists, professionals and other technically trained personnel called in to handle emergencies or other
temporary operations, extra personnel on a unit for training, and other personnel temporarily on a unit for
specialized operations, such as construction, alteration, well logging, or unusual repairs or emergencies.
The CG-543 Policy Letter 02-01, dated February 2, 2002, provides additional guidance clarifying
the Coast Guard’s interpretations of exemptions for specialists, professionals and technically trained
personnel. According to this policy letter, the following factors should be considered in making an
employment exemption determination: (1) job description relative to the units; (2) the period of time
requested or anticipated; (3) type of operations (i.e., temporary, specialized); (4) degree of expertise or
training needed; and (5) safety considerations.
The Vessels
Shell will utilize the Maritime MODU Advisors on the following two vessels:
M/V Noble Discoverer: Self-propelled drillship owned, operated, and crewed by
Noble Drilling International GmbH. Liberian flag (IMO # 6608608).
MODU Polar Pioneer: Mobile Offshore Drilling Unit owned, operated, and crewed
by Transocean. Marshall Islands flag (IMO # 8754140).
The Vessels will be operating on the Alaskan OCS in Chukchi Sea lease blocks 6714, 6762,
6764, 6812, 6912, and 6915.

Personnel and Specialist/Temporary Nature of the Work Performed by the Maritime MODU Advisors
The four individuals that will serve as Maritime MODU Advisors are Mr.
, Mr.
, Mr.
, and Mr.
. These individuals are all permanent Shell
employees based in Shell’s offices in the United Kingdom and Singapore. Specific information on each
of the identified individuals is provided in Enclosure (A).
The following is a brief discussion addressing each of the factors listed in the G-MOC Policy
Letter 02-01:
Job Description Relative to the Unit: The job description for a Maritime MODU Advisor is discussed in
Enclosure (B).
The Period of Time Requested: It is anticipated that the four individuals will perform their specialized
work from approximately June 1, 2015 – November 10, 2015 when activities occur in the Chukchi Sea
OCS. This should be considered temporary in nature, for among other reasons, due to the short openwater season in Alaska.
Type of Operations: As discussed in the background section above and in Enclosure (B), the Maritime
MODU Advisors will perform highly specialized services when the MODU is operating on the Alaska
OCS. In short, the Maritime MODU Advisors will be Shell’s onboard marine assurance representatives
employed specifically to oversee contractor operations to ensure they are conducted in accordance with
applicable regulatory requirements, industry best practices, and Shell’s internal maritime standards to
ensure safe and environmentally compliant operations. Maritime MODU Advisors are neither necessary
nor normally utilized in MODU operations. They are clearly not “necessary for the routine functioning”
of the Vessels. They are neither officers nor crew of the Vessels, they will not stand watches, and they
serve no direct industrial purpose (e.g., their duties are not akin to toolpushers, drillers, roustabouts, floor
hands, crane operators. etc.), and they cannot be considered support personnel (e.g. cooks or stewards).1
Degree of Expertise or Training Needed: Each of the individuals is specifically trained and has extensive
experience performing the functions required of a Maritime MODU Advisor in the offshore Alaska
environment. The Maritime MODU Advisors are highly experienced Shell employees that possess a
specialized level of expertise and in-depth knowledge of the maritime regulatory framework, best
maritime operating practices, Shell’s internal maritime standards, and a mature HSSE culture. These
individuals would report to the Shell Manager of Maritime Assurance through the on board Shell drilling

1

For example, the Policy Letter states that a weld inspection technician aboard a pipe-lay barge to ensure quality
assurance or operate equipment that requires specialized training is not considered part of the regular crew
complement. Clearly, a weld inspection technician performing services onboard a pipe-lay barge to assure quality
or operate equipment would benefit the operations and mission of the barge. Nevertheless, because the technician is
aboard temporarily to provide specialized services, he/she is not considered part of the regular crew complement.
Another example involves drilling advisors that have been authorized for use on drill ships during specialized ultradeep drilling operations following the Deepwater Horizon incident to ensure for the overall safety of operations.
Specifically, “Wellsite Geologists” have been approved to supplement the current crew complement and not replace
any of the U.S. citizen crew. These personnel provide specialized oversight, advice, training, and mentoring of the
crew with regard to drilling operations and they do not stand any watches while onboard the Vessels. These
personnel have been approved for use up to one year at a time in the Gulf of Mexico.

Narrative Summary:
=============================================================================================
16-17 Dec 2014 - CWO
and CWO
attended the MODU NOBLE DISCOVERER at JSL Mega Yard, Tuas,
Singapore at the request of the owner in order to observe and clear PSC deficiencies issued to the vessel in November of 2012
by Sector Anchorage. Met with Captain, Chief Engineer (Contract), and Mr.
(Compliance Director).to discuss the
scope of the examination and the current state of the vessel.
Guided by the form B issued Nov 2012 by Sector Anchorage, the attending inspectors reviewed the vessel statutory certificates,
third party servicing certificates, and logs for accuracy and currency. Additionally, the current DNV survey report from Korea was
available for review as well as the results of the vessel's ISM/ISPS renewal audit. Only four observations were noted on the
auditor’s  report,  These  items  dealt  mainly  with  the  fact  that  the  vessel  had  not  been  operating  since  late  2012  so  records  of drills
etc were not readily available.
Conducted tour of the vessel for familiarization. Ship's crew identified the new rescue boat that was installed during the
Singapore dry-dock and records of the installation tests were provided for review. The four lifeboats on the vessel also had their
releases replaced as per the IMO/USCG requirements. All were satisfactorily tested and documentation of testing provided to the
inspectors for review. All five generators were replaced and testing of the safety shutdowns was conducted in the presence of the
attending inspectors and DNV surveyor. The main engine was replaced in Korea and successful sea trials were conducted in
November of 2014. Initial sea trail was unsuccessful due to improper matching of propeller to hull/engine design. This was
corrected in Singapore and resulted in the successful sea trails being completed in the presence of the DNV surveyor. The SFP
in the engine room has also been replaced. New insulation throughout the engine room was installed as a result of the new
engine installation along with the exhaust system for the main engine. A walkthrough of the machinery spaces also included
inspection of the oily water collection tank that is now included on the vessel's IOPP and documented/approved by DNV. The
OWS was not fully tested in the presence of the attending marine inspectors due to the vessel being in the shipyard and inability
to take suction from the tanks as all bilge water was currently being transferred to shore. However, a cursory inspection of the
OCM including the calibration certificate was deemed satisfactory as well as alarm annunciation in the engine room and via the
Kongsberg system. The attending DNV surveyor did complete a full examination of the OWS during the IOPP renewal survey
and  no  observations  or  comments  were  noted  following  his  inspection.  (see  attached  DNV  Survey  report).  The  ship’s  master  also

identified numerous new self closing fire doors in the accommodations block and pilot house. These were replaced based on the
findings of the PSC inspection in November of 2012. A random sampling of the doors and their closures were all found to be
satisfactory. Electrical transit connections and MCT locations were inspected for the presence of dead end wires / cables and
proper installation / construction of cable transits. These were found to be in satisfactory order as well. DNV survey reports
documenting these items and their corrective actions is attached to this case for review.
The 09 remaining deficiencies were cleared after satisfactory resolution was presented to the attending inspectors and
consultation with the attending DNV surveyor in addition to discussion with Sector Anchorage. Vessel's intentions are to seek a
renewal MODU COC on the USWC upon its return. Vessel currently conducting work up training with ship's crew off the coast of
Malaysia in preparation for return to operation sometime in late 2015..
Inspection completed.
