Sheringham Shoal offshore wind farm secures its submarine cable

The proposed wind farm will cover an area of 35 km 2 in water averaging 20m water depth. It is planned that 88 wind turbine generators, with a unit rating of 3.6 MW, will be connected via a network of infield cables to two offshore substations. The total installed generation capacity will be 315 MW

Nexans has been awarded a contract worth an estimated 24 million Euro to supply the submarine export cables for the Sheringham Shoal offshore wind farm project, located approximately 20km offshore from Sheringham, on England’s north Norfolk coast. The full execution of the cable contract, awarded by StatoilHydro, is subject to offshore development consent from the UK government and the project’s final investment decision, expected during the second half of 2008. The contract includes engineering, procurement and construction of two 22 km 145 kV XLPE (cross-linked polyethylene) submarine export cables, and a spare cable with associated equipment. An optical fibre cable manufactured at Nexans site in Rognan will also be included. The power cables will be manufactured in Norway for delivery in mid April 2010.

and, in an average year, approximately 1.1 TWh of power is expected to be available for export to the regional distribution network at Salle substation. Completion and production start-up of the wind farm is planned for 3rd quarter 2011. The Sheringham Shoal Offshore Wind Farm will be developed
