Prysmian commissions DolWin HVDC link

On 13 November Prysmian announced commissioning of the high voltage direct current (HVDC) offshore grid connection project for DolWin3, an array located off the German North Sea coast. Prysmian 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 km offshore in the North Sea, to the national grid on the German mainland. As a turnkey service provider, Prysmian was responsible for the supply, installation and commissioning of the ±320 kV HVDC extruded submarine and land power cable connections with a rating of 900 MW, and the associated fibre optic cable system, covering in all a 78 km land route and an 83 km 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).

“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,” commented Hakan Ozmen, EVP Projects, Prysmian Group.

The completion and handover of this project confirms the Group’s ongoing successful relationship with TenneT, which in recent years has awarded a total of seven HVDC grid connection projects to Prysmian, including BorWin2 & BorWin3, Helwin1 & Helwin2, SylWin1 and the recently awarded Dolwin5.
