BPOutline designs for new North Sea platforms have been unveiled by BP as part of its spending plans for four major projects costing US $5 Bn in the next five years.

Tapping the Skarv field in the Norwegian North Sea sector could include a platform with 16,500 tonnes (t) topsides supported by a 35,000 t hull, plus another 9,000 t turret and mooring system if a floating production solution is pursued.

Topsides processing capacity would cover 185,000 b/d of oil and 670 Mmcf/d of gas. Also a 70 km (43 miles) flow line is indicated to export production.

Redevelopment of Valhall will involve the replacement of three existing platforms with one new facility equipped with 11,200 t topsides and a 6,000 t jacket. This new installation would require process capacity of 150,000 b/d of oil and 775 Mmcf/d of gas handling capacity, plus a 290 km (181 mile) power cable from shore to avoid offshore power generation.

Harding is also scheduled to take production from BP’s forthcoming Devenick development, and the new facility would be bridge-linked back to the existing Harding TGP platform.

Clair phase two will be a “clone” of the phase one platform which came onstream in February last year (pictured). This second Clair platform, with 60,0000 b/d oil processing capacity and 25 Mmcf/d of gas handling, would be based on 14,000 t topsides and a 10,000 t jacket.

Mustang Engineering owned by Aberdeen-based Wood Group designed the first Clair platform, which was built to a radical new fit for purpose design based on Gulf of Mexico platform construction conventions.

Details on the new platforms were outlined in a new North Sea strategy presented by Terry Hughes, formerly project manager for Clair, and now director of major projects for BP’s North Sea Strategic Performance Unit.
