Cable-laying work has been completed for EnBW’s 960-megawatt He Dreiht offshore wind farm, marking a major milestone in Germany’s largest offshore wind project, Seaway7 said on Tuesday.
The final inner-array cable has been installed, completing approximately 100 kilometres of cable to connect the 13th and last turbine string to the BorWin5 converter platform. The first cable was laid on March 10, following the engineering, procurement, and construction phase.
Seaway7 deployed its cable-laying vessel Seaway Aimery and support vessel Seaway Moxie to carry out the work. A total of 64 cables have now been laid and pulled into place, with Seaway Aimery currently trenching the final sections and Seaway Moxie completing stripping, routing and jointing operations.
Located about 90 kilometres northwest of Borkum and 110 kilometres west of Heligoland, the He Dreiht wind farm—named after the German phrase meaning “It Spins”—will feature 64 turbines and is expected to supply renewable energy to around 1.1 million households upon completion.
He Dreiht is among the first offshore wind projects in Germany to proceed without public subsidies and will double EnBW’s existing offshore capacity of 976 megawatts.
“This marks a key step forward for He Dreiht,” Seaway7 said in a statement. “With the cables in place, the project moves closer to delivering clean electricity at scale.
