Allseas’ building vessel Pioneering Spirit has accomplished the infield pipelay scope for BP’s ultra-deepwater Higher Tortue Ahmeyim (GTA) liquified pure fuel challenge offshore Mauritania and Senegal.
Two months after arriving within the discipline, manufacturing crew welded, scanned and discipline joint coated the ultimate piece of pipe for the second 16-inch export fuel line.
Safely landed in a 2-metre goal field at 2400-meter water depth, the pipeline will likely be recovered in J-mode configuration to put in the termination meeting.
To make this occur, the vessel aft has been fitted with a bespoke J-mode body with a 1000-tonne load capability, which was designed, constructed and put in on board in solely eight weeks by Allseas’ engineering and fabrication groups.
The pipelay scope contains roughly 75 km of 16-inch export traces and 10 km of 10-inch CRA infield traces, a number of the pipeline infrastructure exceeding 2700 meters water depth on the deep finish.
The primary firing line and double jointing services on Pioneering Spirit have run in parallel all through the marketing campaign. Pioneering Spirit will conclude the offshore works by putting in the six excellent flowline termination assemblies.
“Our Agile method was key to a fast and environment friendly begin to the challenge and decision-making course of all through the offshore marketing campaign. Because of nice collaboration between the onshore and offshore groups, we’ve overcome all challenges confronted in the course of the challenge preparation and execution phases and met all milestones immediately,” mentioned Laurent Beghin, Allseas Venture Supervisor.
Kosmos Power found the GTA discipline in 2015, with BP signing onto the challenge by means of an settlement with Kosmos in 2016 as challenge operator.
The challenge’s first part is ready to supply round 2.3 million metric tons of LNG per 12 months. GTA contains each FPSO and FLNG services.
The FPSO will course of pure fuel and export it by pipeline to the challenge’s FLNG services, 10 km offshore. With eight processing and manufacturing modules, the FPSO will course of round 500 million normal cubic toes of fuel per day.
