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.
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.
