ABERDEEN, UK – STATS Group has successfully completed a 20 in. valve change-out on the Yanga platform, offshore the Republic of Congo.

The company was contracted by Halliburton, on behalf of Total E&P, to provide pipeline isolation to replace a launcher valve located downstream between the Yanga export and Sendji production lines.

The Sendji production line was to remain live and online during the valve intervention works. Following a full site survey STATS proposed the use of a of a 20 in. Tethered Tecno Plug as the primary isolation, with an additional modified 24 in. Tecno Plug deployed to isolate the launcher door and provide umbilical management.

Once valve change-out was complete and with the Tecno Plug continuing to provide safe isolation, STATS deployed a 20 in. In-Line Weld Test Tool to carry out a leak test on the reinstated flange joint. Due to the timely completion of the isolation and valve change-out, the operator carried out an additional change-out of three valves, saving the operator time and providing a cost-effective solution.

The six day operation was worth a six-figure sum and is STATS first project completed in the Republic of Congo.
