McDermott Completes Pipe Work for Woodside
US contractor McDermott International said September 4 it has completed the second phase of the Greater Western Flank project offshore Western Australia. The contract, valued at somewhere between US$50mn-$200mn, was awarded by Woodside Energy in January 2016.
The gas it will produce will help extend the life of the Woodside-run North West Shelf LNG and domestic gas supply venture - which this week loaded its 5,000th LNG cargo in 29 years of operation.
McDermott was responsible for procurement, fabrication, installation and testing of a series of pipeline buckle initiators, pipeline end terminations and foundation mudmats, in-line tee structures and some 21 miles (35 km) of a 16-inch (40 centimeters) corrosion resistant alloy (CRA) pipeline extending from the existing Goodwyn A Platform to the Lady Nora and Pemberton field manifold locations.
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 miles to 37 miles (40 km to 60 km) 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 4Q2018.
In its 1H2018 results last month, Woodside said the Greater Western Flank Phase 2 (GWF-2) project was 91% complete with a forecast final cost of A$230 million net to Woodside's 16.67% share - so A$1.38bn (or US$992mn) at 100%. It said that was about 30% under the approved budget, when final investment decision was taken, with cost savings achieved through drilling performance and other areas. Woodside added that GWF-2 is "on schedule for 1Q 2019" and is designed to produce at up to 0.8bn ft3/d (8.3bn m3/yr) at plateau (100% equity).
