Prysmian Group has announced the commissioning of the high-voltage direct current (HVDC) offshore grid connection project DolWin3, off the German North Sea coast.
Prysmian, a global energy and telecom cable systems group, 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 about 85 km offshore in the North Sea, to the German mainland, with the purpose of transmitting 900 MW of clean and renewable energy into the national grid.
Prysmian was responsible for the supply, installation and commissioning of the 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-km land route and an 83-km subsea route.
The cables were produced at the Prysmian Group’s centers of technological and manufacturing excellence in Arco Felice (Italy), Pikkala (Finland) and Delft (The Netherlands).
“We are very proud of having contributed to the development of such an important renewable energy project proving our ability to provide tailor-made submarine cable solutions to support the growth of clean energy in Northern Europe,” stated Hakan Ozmen, EVP projects, Prysmian Group.
The completion and handover of this project further confirms the group’s ongoing relationship with TenneT, which in recent years has awarded seven HVDC grid connection projects to Prysmian, including BorWin2 and BorWin3, Helwin1 and HelWin2, SylWin1 and the recently awarded DolWin5.
