Prysmian has delivered the HVDC offshore grid connection project DolWin3, off the German North Sea coast.
The Italian subsea cables specialist had secured this project in February 2013, with a contract awarded by Alstom Grid (now GE Grid GmbH) on behalf of the 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 kilometers offshore in the North Sea, to the German mainland.
Prysmian 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 kilometers land route and an 83 kilometers subsea route.
The cables were produced at the Prysmian Group’s centres of technological and manufacturing excellence in Arco Felice (Italy), Pikkala (Finland) and Delft (The Netherlands).
