PASSIVE ACOUSTIC SUBSEA LEAK DETECTION & LOCATION SERVICES
HYDROTEST SUPPORT • INTEGRITY CORROBORATION & ASSAY
PRODUCT FLOW RESTRICTION ISSUES • ACOUSTIC INVESTIGATIONS
All subsea components exhibiting a contained-to-ambient pressure differential or internal fluid flow, including:
Pipelines • Risers • Flanges • Valves • PLETs/PLEMs • BOPs • Caps • Pig Launchers • Stuck Pigs • Piggable Wyes • Manifolds
RSA’s unique real-time techniques have saved our clients millions of dollars, and weeks of operational delays.
RSA specializes in the use of passive acoustics to inspect, diagnose—and in some cases remediate—underwater & deepwater petroleum infrastructure and all associated pressure-containing & active-flow components. Our services are most often employed concurrently with hydrotesting during or following completion, refurbishment, repair, and commissioning operations, where we rapidly locate & define problems, and corroborate integrity. As a measure of the degree trust our clients place with us, RSA is often mobilized to, or prepositioned near, the field location of interest, and asked to standby, at varying degrees of readiness, in case an issue arises.
Our services have proven effective with virtually all subsea petroleum infrastructure components, including valves, pipelines, risers, and couplings, including concealed & internal items. They are also used to assist & intervene with operational (i.e., product-containing) installation issues, such as whether a valve is thru-leaking or sealed, and predicting the location of internal obstructions, as with stuck pigs.
RSA methods are deployed via ROV or diver (Flocator), or when appropriate, in a ship-towed mode (Towcator). 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 has been successful whether deployed alone or in tandem in with side-scan sonar. In certain scenarios, RSA has provided rapid solutions unattainable by any other known methods or service providers, avoiding any need to disassemble & recover subsea components for inspection and replacement.

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