The Statfjord A platform in the North Sea will shut down production in 2022, 43 years after first oil. This more than doubles the expected lifetime of the platform. Now the contract for removal and disposal of the topside has been signed, and the topside will be demolished at Stord – where it was built in the 1970s.
The contract for the engineering work, preparations, removal and disposal of the topside has been awarded to Excalibur Marine Contractors, a company in the Allseas group. Kværner AS at Stord has been hired by Excalibur to dismantle and recycle the topside onshore.
The 48?000-tonne topside structure will be removed from the concrete legs in one single lift by the Allseas vessel the Pioneering Spirit:?
“The vessel has done an excellent job installing three of the four Johan Sverdrup topside structures. Now they get to show their strength at the other end of an oil field’s life cycle,” says Peggy Krantz-Underland, Equinor’s chief procurement officer.
The Statfjord oil field is an enormous oil and gas field covering 580 km2 in the U.K.-Norwegian boundary of the North Sea at a water depth of 145 m, discovered in 1974 by Mobil and since 1987 operated by Statoil. he Statfjord field has three condeep concrete production platforms, A, B and C. Each platform is made up of approximately 250,000 tonnes of concrete with 40,000 tonnes of top-side processing and accommodation facilities.
The field holds the record for the highest daily production ever recorded for a European oil field (outside Russia) : 850,204 barrels (135,171.6 m3) (crude oil plus natural gas liquids) were produced on January 16, 1987.
