Subsea Leak Detection & Location Services

100% field-proven results

Rapid in-field deployment via ROV, diver or ship-towed vehicle

Pipelines - risers - valves - all subsea components exhibiting a contained-to-ambient pressure differential, or internal fluid flow

RSA provides call-out services for detecting & locating active leaks & other problems involving anomalous fluid flow. While most often employed to rapidly locate problems & validate repairs during hydrotest & other completion/refurbishment operations, these services are also used to intervene with operational installations. They are applicable to virtually all subsea petroleum installation components, including valves, pipelines, risers, & couplings, including concealed & internal items.

 


Flocator installations on ROVs (L & C images–port manipulators; R–stbd)

RSA methods are deployed via ROV or diver (Flocatorsm), or when appropriate, ship-towed vehicle (Towcatorsm). RSA technology provides rapid results, typically outperforming diver, video-inspection & dye methods, & overcomes various operational complications & costs inherent in such conventional approaches. Apart from inspecting discrete components, Flocator is well-suited for use during pipeline video flyover surveys. Towcator is similarly suited to tandem operations with side-scan sonar. In certain scenarios, RSA has provided rapid solutions unattainable by any other known methods, completely avoiding the need to recover subsea installation components for inspection.

 


Towcator, tandem installation w/side-scan sonar, & navigation responder

RSA has saved clients millions of dollars & weeks of operations on single projects. Proven capabilities of these real-time & highly interactive techniques include:

• Pipelines, risers, spool pieces, connection devices, valves, flanges, flowlines, pigging assemblies, control lines
• Hydrotest & gas-pressure test support
• Rapid validation of repairs without waiting for hydro or gas-pressure results
• Monitor discrete locations (spool pieces, collet connectors, flanges, valves)
• Pipeline flyover mode compatible with normal video inspection surveys
• Reverse leaks (dewatered/gas-filled deepwater pipelines & completion assemblies)
• Valve thru leaks, & forward or reverse stem leaks
• Pipe-in-pipe leaks
• Leak location in gas-filled lines where local flooding may preempt visual detection of bubbles
• Real-time valve-closure guidance & confirmation
• Obstruction location, where blow-by exists
• High degree of integrity prediction where conventional pressure/volume methods are inapplicable
• Advance notice of pig arrival
• High-speed (up to 4kts) assay of longer pipelines (Towcator)

Additional capabilities: RSA's personnel have provided leak detection & location services for land facilities, including buried pipelines, valves, & above-ground storage tanks. The versatile technology can often provide off-the-shelf solutions for unusual field & concept-development problems. Several R&D & D&D tests & projects have been conducted & coordinated for oil majors & industry groups, some in conjunction with university facilities.

RSA is based in Elfin Forest, California, USA.
