Subsea leak detection capability has become more important to the offshore oil and gas industry in the past few years due to industry issues with subsea leaks and the inability to quickly identify these leaks. This has driven the industry to find solutions that better monitor and expedite determination of whether a subsea leak exists, minimizing the time to shut in affected infrastructure in the event a leak. Over a short period of time, a small team of experts at Tesla Solutions Inc. working for LLOG Exploration was able to establish new internal standards for subsea leak detection and implement on an operating facility, WhoDat, in the Gulf of Mexico. Understanding that BSEE may soon require systems to meet tighter standards, TSI anticipated, developed and implemented standards for a leak system that delivers a complete, repeatable program available to industry which included delivery of functional requirements, HMI screens and tools, operator training for the specific well(s)/flowline(s), ongoing monitoring of quarterly data while in operation allowing for continuous improvement, and annual testing of the system.
