Cable company Nexans has been awarded a contract by project developer Offshore-Windpark Riffgat, owned by Enova and Ewe Energie, to supply and install the infield submarine power cables and ancillary equipment for the Riffgat offshore wind farm, currently under construction 15km northwest of the German island of Borkum.
Covering an area of 6km2, the Riffgat wind farm will comprise 30 wind turbines providing a peak capacity of 108MW, sufficient to meet the needs of around 100,000 households.
The Nexans facility in Hannover, Germany, will design and manufacture 24km of 33kV XLPE submarine infield cables to interconnect the wind turbines and to link them to the offshore transformer substation.
Nexans in Norway will be responsible for the cable installation, which includes engineering, laying the cable and pulling in each cable end to the wind turbines, as well as protection of the cables on the seabed using the Capjet trenching machine.
Delivery of the Riffgat cables will take place in autumn 2012, with installation scheduled to commence in July the same year.
