Prysmian Wins Dolwin5 Cabling

Prysmian has been awarded a grid connection project worth in region of €140 million by the Dutch-German grid operator TenneT which will enable the connection of multiple offshore wind farms to the German grid.

“The Dolwin5 project continues our valued long relationship with the major TSO TenneT and demonstrates our ability to provide tailor-made submarine cable solutions for challenging projects, providing the offshore infrastructure needed to support the growth of clean energy in Northern Europe.” stated Hakan Ozmen, EVP Projects, Prysmian Group.

The project involves the supply, installation and commissioning of a High Voltage Direct Current (HVDC) 320 kV XLPE-insulated submarine and land power cable connection, with a transmission capacity of 900 MW, as well as the associated fibre optic cable system, comprising a land route of 30 km and a subsea route of 100 km.

The turnkey connections will link the offshore converter platform DolWin epsilon, located approximately 100 km offshore in the German North Sea, to the mainland Emden/Ost converter station, with the purpose of transmitting the generated renewable energy into the German grid.

The submarine and land cables will be manufactured at Prysmian’s centres of technological and manufacturing excellence respectively located in Pikkala (Finland) and Gron (France).

Offshore installation activities will be performed by two of cable laying vessels — Cable Enterprise, for deep water installation, and Ulisse, for shallow water activities.

Completion of the project is scheduled for the middle of 2024.
