nkt cables has signed an offshore high-voltage cable contractnkt cables GmbH and RWE Innogy in Germany have today signed a contract for the manufacture and delivery of a high voltage submarine cable for the Welsh offshore wind farm Gwynt y Môr. In total, nkt cables will produce 85 kilometres of high voltage three core submarine cables. The contract volume is around EUR 35 million.



"The HV submarine cables for the Gwynt y Môr offshore wind farm will be produced in our new factory in Cologne", says Dion Metzemaekers, CEO nkt cables and continuous: "nkt cables will be responsible for the delivery of all HV submarine cables and accessories of the transmission system for the wind farm. In total, nkt cables will produce four 132 kV high voltage three core submarine cables for RWE Innogy at our newly built cable plant "f2c" (flow to customer) in Cologne. Manufacturing of these ables will begin at the end of 2011, the construction of the wind farm at sea begins at the same time and the cable will be delivered in mid of 2012."

The high voltage submarine cables will, when manufactured, be taken via the Rhine to Rotterdam. A special cable-laying vessel will deliver the cables to Liverpool Bay off the coast of North Wales. Later, these high voltage cables will transmit the energy produced by the total of 160 wind turbines of the Gwynt y Môr wind farm across 13 kilometres to the coast, where the closest feeding point on land is located at St Asaph.

Each of these cables has a diameter of around 20 centimetres and is protected with a robust armouring against the extreme loads at high sea, such as corrosion or abrasion through tides and waves. At the same time these cables enable a maximum energy transmission over long distances.
