Siem Offshore Contractors GmbH (SOC), a wholly owned subsidiary of Siem Offshore, won a contract for the turnkey supply and installation package of the inter-array grid cable system for the Nordsee One in April 2014.

The wind farm’s 54 6.15MW turbines will be connected to the offshore substation by ten strings of cables with an overall length of approximately 70 kilometres.

Nordsee One is owned by Northland Power Inc. (85%) and RWE Innogy GmbH (15%). The wind farm is located approximately 40 kilometres north of the island of Juist in the German part of the North Sea.

The commissioning of the wind farm is scheduled for 2017.
