The DLV 2000 is expected to join the project in 2Q 2016 and will install large subsea spools, lay infield umbilicals, and lift several subsea distribution units that will provide the hydraulic, chemical, and electrical distribution from the umbilicals to the subsea drill centers.
The DLV 2000 is a DP-3 vessel that combines a 2,200-ton revolving crane with a deepwater S-lay pipelay system configured to install pipelines with diameters ranging from 4.5 to 60 in. in water depths up to 10,000 ft (3,048 m). The vessel can accommodate up to 400 personnel to facilitate large hook-up and commissioning projects and incorporates a large, 43,000-sq ft (3,995-sq m) open deck to allow the transportation and assembly of large subsea structures.
Work is expected to be performed in conjunction with the company’s other new subsea installation vessel, the Construction Support Vessel 108 (CSV 108), that is already working on the project.
Later this year the CSV 108 is expected to undergo an upgrade to install a vertical lay system and reel deployment system, also for use in the project and will then be referred to as Lay Vessel 108 (LV 108).
Woodside has awarded McDermott a transportation and installation contract for the Greater Western Flank Phase 2 project. The installation will occur approximately 20 mi (32 km) from the Goodwyn A platform located in the North West Shelf region off Western Australia.
The full scope of the brownfield project covers transportation and installation of 22 mi (35 km) of 16-in. corrosion resistant alloy clad pipeline which includes three in-line tees and pipeline end terminations at each end in water depths up to 420 ft (128 m).
Work is expected to be performed by the DLV 2000 in conjunction with the CSV 108.
Engineering for the project is expected to be done by the company’s in-house staff in Perth and Kuala Lumpur. Fabrication and pre-installation of pre-lay support structures and 21 buckle initiators is scheduled for its Batam Island, Indonesia, fabrication facility.
