Red Marine, based in Hexham, has completed a qualification testing program on a new vent valve for FMC Technologies. The program to validated the performance of the vent valve against industry standards including ISO 10423 (API 6A). Used during workover operations, the valve enables redistribution of high pressure oil and gas within the landing string system to allow for emergency riser disconnection.
Delivered in 12 weeks, the test program included the design and supply of the test assembly and its complex multi-pressure hydraulic control system.
Working closely with members of the FMC Well Access Systems team, the test equipment was initially used to complete a variety of static pressure tests of up to 15,500 psi (1067 bar) and demanding cycle tests to assess valve function and seal endurance. On completion of this phase, a series of outstanding rapid decompression tests were also completed using water, sand slurry and nitrogen gas test media.
