Norddeutsche Seekabelwerke (NSW), a subsidiary of General Cable, has been contracted by Van Oord, an international marine contractor, to design, manufacture and deliver inter-array cables for Deutsche Bucht offshore wind farm.
Per a report in subsea world news, the NSW will deliver 45 km of medium-voltage submarine power cables for the Deutsche Bucht, which is owned by Northland Power. Delivery of the submarine cables is scheduled for spring of 2019, the company said.
Van Oord will deploy its offshore installation vessel Aeolus and cable-laying vessel Nexus for the installation works. The Deutsche Bucht offshore wind farm is located in the North Sea, approximately 95 km north-west of the island of Borkum. It includes 31 MHI Vestas Offshore Wind 164-8.0 MW (8.4 MW Power Mode) turbines, which will generate a total output of 252 MW..
The Prysmian Group announced that it has been awarded a contract by Cobra Wind International Ltd. to provide the cable system to connect the Kincardine Floating Offshore Wind Farm to mainland U.K.
A press release said that the order, Prysmian’s first cable project for a floating offshore wind farm, calls for the design and supply of two export cables as well as inter-array cables and associated accessories to connect the turbines. The Kincardine Wind Farm, is some 15 km southeast of Aberdeen, to the Scottish mainland power grid.
Each of the continuous export cables will serve the 17 km route, using a static cable design combined with a 0.5 km dynamic cable route section to complete the connection to the floating turbine tower. The 33 kV three-core submarine cable will use EPR insulation system, with the static section length finished with single wire armoring, while the dynamic section will employ a double-wire armored design. The submarine cables will be produced at the Group plants in Vilanova, Spain, and Drammen, Norway. Installation is planned during 2018 and 2019.
The Kincardine project is planned to be built in two stages. A single turbine 2 MW first phase is scheduled to be installed this year, followed by a six-turbine second phase with hardware of up to 8.4 MW each. The first phase will consist of a Vestas V80 2 MW machine with a 106-meter tip height and 80-meter rotor diameter.
