Prysmian wraps up cable installation work for TenneT at Dolwin3 wind farm

Italy’s Prysmian Group has completed design, supply, and installation of cable systems at the DolWin3 offshore wind farm in Germany.

The company was responsible for the supply, installation, and commissioning of the high voltage direct current (HVDC) ± 320 kV extruded submarine and land power cable connections with a rating of 900 MW and the associated fibre optic cable system, covering a 78-kilometre land route and an 83-kilometre subsea route.

The work was carried out as part of a contract originally awarded in February 2013 by Alstom Grid, now GE Grid, on behalf of Dutch-German grid operator TenneT.

DolWin3, the third offshore grid connection in the DolWin cluster, links the offshore converter platform DolWin Gamma, located approximately 85 kilometres offshore in the North Sea, to the German mainland with the purpose of transmitting clean and renewable energy into the national grid.
