TONSNERG, Norway --Grenland Group has completed assembly of the subsea separation equipment for Statoil's Tordis development.
The three modules will form part of what is claimed to be the world's largest full-scale subsea water and sand separation unit. It will allow Statoil to recover an extra 35 MMbbl of oil from Tordis in the Norwegian North Sea, 11 km (6.84 mi) south of the host Gullfaks C platform. This also will lift the field's overall recovery factor from 49% to 55%.
According to plan, the modules will be transferred onto a barge stationed outside the yard. A crane vessel then will lift the modules and the manifold onto the 19 m high (62.33 ft), 40 m long (131 ft), 25 m wide (82 ft) template, also under construction at Tonsberg.
