The majority of the contracts valued at £900 million have been entered into by the German multinational Siemens to acquire 175 3.6-MW wind turbines. The subsidiary Siemens Transmission and Distribution will be responsible for the electrical systems of both the two offshore and the onshore substations.
Another beneficiary is the Norwegian electrical engineering group Nexans Norway, which will supply the 220 kilometres of cable connecting the wind farm to the main onshore substation. JDR Cable will also supply the 210 kilometres of cable needed to connect each wind turbine to its neighbour, while Visser & Smit Marine Contracting and Global Marine has been awarded the tender to lay down all the cabling.
Meanwhile, the Scandinavian engineering firms Per Aarsleff and Bilfinger Berger have been awarded the contract to lay down the foundations for the turbines, and a joint venture between Future Energy, Fabricom, Iemants and Geosea will be responsible for manufacturing and installing the substations.
