McDermott said Tuesday it has completed the contract for phase two of the Greater Western Flank project in Australia.
The contract was awarded by LNG operator Woodside Energy in January 2016.
McDermott was responsible for the procurement, fabrication, installation and testing of a series of pipeline buckle initiators, pipeline end terminations and foundation mudmats.
The company also installed in-line tee structures and approximately 21 miles (35 kilometers) of a 16-inch (40 centimeters) corrosion resistant alloy (CRA) pipeline extending from the existing North West Shelf (NWS) project’s Goodwyn A Platform to the Lady Nora and Pemberton field manifold locations.
McDermott deployed two of its specialty vessels to complete the installation phase, namely DLV 2000 for the pipelay campaign and the Lay Vessel 108 for the pre-lay and post-lay campaign.
McDermott also 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 fields lie in water depths varying between 262 feet (80 meters) and 426 feet (130 meters) at approximately 29 to 37 miles (40 to 60 kilometers) southwest of the Goodwyn A Platform, located off the northwest coast of Western Australia.
It includes the development 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.
The project is expected to achieve first gas by the end of this year.
