Cable systems provider for energy and telecom sectors Prysmian Group has completed the commissioning of the high voltage direct current (HVDC) offshore grid connection project DolWin3, which is located off the German North Sea coast.
In February 2013, the contract was awarded to Prysmian by Alstom Grid, (which is now GE Grid) on behalf of Dutch-German grid operator TenneT. Prysmian Group was responsible for providing design, supply and installation of the cable systems.
Prysmian Group Projects executive vice-president Hakan Ozmen said: “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.”
Part of ‘DolWin’ cluster, DolWin3 is the third offshore grid connection that will connect the offshore converter platform DolWin Gamma, stationed nearly 85km offshore in the German North Sea.
For this project, Prysmian installed and commissioned HVDC ± 320kV submarine and land power cables with a rating of 900MW.
The company also provided related fibre optic cable system, which covered the 78km land route and an 83km subsea route.
Prysmian further added that the cables for this project were manufactured at its centres of technological and manufacturing excellence located in Arco Felice in Italy, Pikkala in Finland and Delft in the Netherlands.
In total, TenneT has awarded seven HVDC grid connection projects to Prysmian Group including BorWin2 & 3, HelWin1 & 2 and SylWin1.
Prysmian will be responsible for the supply, installation and commissioning of a high voltage direct current (HVDC) 320kV XLPE-insulated submarine and land power cable connection.
