The alternating current (AC) cable will be used at the 400 MW Dudgeon offshore wind farm, which is owned by a joint venture between Statoil and Statkraft, which are also building Sheringham Shoal offshore wind farm (pictured) in Britain.
Dudgeon’s turbines will be located in waters 18-25 meters deep, around à‚ 32 kilometers off the coast of Norfolk on the east coast of England.
ABB will design and supply two 132 kV three-core AC submarine cables, each 42 km long, running from the wind farm’s offshore substation to land, where they will connect to onshore cables. The submarine cables will be manufactured at ABB’s high-voltage cable factory in Karlskrona, Sweden, and delivery will start in 2016.
Claudio Facchin, head of ABB’s power systems division, said: “Offshore wind is a growing renewable energy resource, with Europe accounting for around 70 per cent of new offshore wind generation capacity. Transporting electricity from offshore wind farms to the shore and then integrating it into the grid for supply to consumers are key elements.”
Bjorn Ivar Bergemo, asset manager of the company Dudgeon Offshore Wind Farm, said the cables “will be some of the longest ordered so far for a UK offshore wind project”.
