BP PLC has let a contract to Technip for subsea work in its redevelopment of Schiehallion and Loyal oil fields in the West of Shetland area offshore the UK.
The project, which BP calls Quad 204, includes replacement of the Schiehallion floating production, storage, and offloading vessel with a unit under construction by Hyundai Heavy Industries (OGJ Online, July 13, 2011). The fields, on production since 1998, are in 350-500 m of water.
Under a contract worth about €600 million, Technip will remove the existing FPSO and mooring system; recover existing flexible risers and dynamic umbilical systems; position and install the new FPSO and associated mooring system and anchor piles; supply and install 21 dynamic flexible risers; install four static and dynamic umbilicals; coat, weld, and install 15 steel pipelines totaling 50 km; supply and install numerous flexible jumpers; and install various manifolds, jumpers, and infrastructure associated with field development.
The new FPSO will be 270 m long and 52 m wide, with capacity to handle production of 130,000 b/d and store more than 1 million bbl.
New facilities are to start production in 2016.
