Siemens has been contracted to carry out the entire maintenance of the two North Sea grid connections HelWin1 and BorWin2. The two contracts, awarded by the Dutch grid operator TenneT, are initially for a period of five years.
Siemens will establish a service base in Lower Saxony close to the coastline for the offshore and onshore converter stations. The services covered by the contract include preparing the maintenance schedules, coordinating and executing inspections, preventive maintenances and repairs, and providing the related logistics and spare parts management services. The wind farms are located between 85 and 125 kilometers offshore, to the north-west of the islands of Borkum and Helgoland. The BorWin2 grid connection will have a transmission capacity of up to 800MW, HelWin1 a capacity of 576MW. Both connections will be built using high-voltage direct current (HVDC) transmission technology with submarine cables, and are scheduled to be ready for operation in 2013.
