Intervention

The right systems for your leakdetection and pipeline integrity needs.
Our technologies reveal extremely low concentrations of hydrocarbons and minute traces of dye and organic compounds, providing early detection of even the smallest leaks. And fast, efficient inspections reduce standby costs for high-priced construction spreads.
Weatherford’s independent leak-detection systems are capable of finding extremely small leaks, regardless of pipeline product, water current, visibility or even minimal pressure differential conditions. Early detection helps maintain pipeline integrity and avoids serious failures after commissioning that can result in suspended production, environmental damage and costly repairs. The sooner you know where the problem is, the sooner you can take corrective action to get your pipeline back online. The sensitivity, versatility and speed of our systems help minimize exposure to expensive marine construction repair spreads and contribute directly to your bottom line.

Subsea Pipeline Leak Detection

Programmable mass spectrometers gather
continuous samples along pipeline routes or near subsea assemblies to determine the presence of compounds with an atomic mass of 1 to 150. Measurements are in real time, and the system can be preprogrammed to search for specific compounds. It is capable of detecting trace hydrocarbon as small as 1 ppb. Applications:

Dye-detector systems
provide maximum leakdetection performance regardless of water clarity or current. Deployable by ROVs or held by a diver, the systems can detect traces of dye as small as 1 part per billion (ppb). Colored or clear fluorescein dyes can be used based on specific needs. Applications:

• Close-up inspections of accessible
potential leak paths

• Specific volatile compound searches • Hydrocarbon contamination mapping in seafloor soils • Buried broken pipeline and leaking well identification

• Difficult-to-access fittings within large
or complex subsea components using extended-range sensors

• Long pipelines at optimal ROV speeds • New construction or following in-service
system repairs

BigEars™ passive acoustic systems can
be deployed on remotely operated vehicles (ROVs) or by divers and can “hear” acoustic energy emitted when liquid or gas seeps through a defect or leak path. Water clarity is not an issue, and background noise is eliminated from the display using sophisticated calibration techniques. Applications:

The Didson™ activeacoustic system sends
near-video-quality, black-andwhite images to the surface. The system can detect tiny gas or oil bubbles in the water column at distances of up to several meters regardless of water clarity. It minimizes risk associated with diving operations, enhancing safety during construction and salvage jobs. Applications:

• New construction or in-service systems • Internal bypass in in-line valves and reverse
leak detection

• With dye detectors or as standalone when dye
is not an option

• Gas or oil bubble water column detection • Post-hurricane pipeline and structure inspection • Surrogate for ROV optical cameras in zerovisibility conditions
