McDermott connects GWF-2 fields to Goodwyn A
McDermott International has completed a pipelay program for the Greater Western Flank Phase 2 project offshore Western Australia for Woodside Energy.
The scope comprises procurement, fabrication, installation, and testing of pipeline buckle initiators, pipeline end terminations and foundation mudmats, in-line tee structures and around 21 mi (35 km) of a 16-in. (40-cm) corrosion resistant alloy pipeline from the Goodwyn A platform to the Lady Nora and Pemberton field manifold locations.
“One of the key challenges of the project was to perform installation work inside the 546 yards [500 m] safety zone of Woodside’s Goodwyn A platform,” said Vince Vieraitis, McDermott’s GWF-2 Project Director.
The company deployed theDLV 2000 for the pipelay campaign and the lay vessel 108 for the pre-lay and post-lay work.
In addition, it set up an onshore portable and temporary double jointing facility at its Batam fabrication yard in Indonesia to simulate the offshore installation campaign.
The Greater Western Flank Phase 2 project spans water depths ranging from 262-426 ft (80-130 m), 29-37 mi (40-60 km) southwest of the Goodwyn A platform.
It includes drilling of eight wells from the Keast, Dockrell, Lady Nora, Pemberton, Sculptor and Rankin fields.
Gas production is tied-back via the pipeline end termination, in-line tees and subsea pipeline to the platform. First gas should flow by year-end.
