Heerema reported today that the largest offshore deck ever built in the Netherlands is being moved outside for final fabrication efforts. The massive Processing and Hotel (PH) platform deck is being built for the redevelopment project on the Valhall field offshore Norway.
BP (BP) awarded the Valhall PH fabrication and integration contract to Heerema in March 2007. The original contract consisted of an 11,000-ton Integrated Production and Hotel Facility topsides, as well as a 350-ton flare boom. Fabrication on the facilities commenced in Nobember 2007.
Following the initial contract, BP awarded Heerema the contract to construct the 2,000-ton weather deck module, as well.
Although Heerema's Zwijndrecht, Netherlands facility is one of the largest in the world, it cannot accommodate the final topside facility, and the topsides has moved outside for completion. In fact, the BP Valhall main deck measures 100 meters long by 47 meters wide and 50 meters high. Once construction has been completed, the Valhall HP will weigh more than 13,000 tons.
The completed Valhall topsides, which will consist of a main deck, weather deck, flare boom and two bridges, is scheduled to leave the Heerema fabrication facility in the Netherlands in May or June 2010.
Aker Solutions was awarded the hook-up of the Valhall PH platform in December 2009.
Valhall Redevelopment Project
Valhall was discovered in the Norwegian waters of the North Sea in 1975, and production commenced on the field in 1982. Situated in waters measuring 75 meters deep, the Valhall complex originally consisted of five different platforms, including the quaters, drilling, wellhead, production and water injection platforms, which were all interconnected via bridges, as well as two unmanned flank platforms.
The Valhall Redevelopment project involves the construction and installation of a the PH platform, which will have a production capability of 120,000 barrels of oil per day and 143 million cubic feet per day of natural gas.
