Dutch dredging contractor and marine services provider Boskalis, in consortium with TKF Subsea Solutions, has signed a contract for the supply and installation of approximately 140 km of 66 kV inter-array cables for the Gennaker offshore wind farm in the German Baltic Sea.

As part of the scope, Boskalis and TKF will deliver the complete inter-array cable system connecting the future 63 wind turbine generators in the Skyborn Renewables-developed offshore wind farm.

The cables will be manufactured in the Netherlands by TKF, after which Boskalis’ specialised cable-laying vessel Boka Ocean will install them from the end of 2027. The contract represents a sizable value, in the range of €50-150m ($59-177m).

With a planned capacity of 976.5MW, Gennaker will become the largest offshore wind farm in the German Baltic Sea, supplying about one million households with clean energy. Commissioning of the project is planned for 2028.

Boskalis is already active on the project through its subsidiary Heinrich Hirdes EOD Services, which is conducting an identification and clearance campaign for unexploded ordnance, for which it has mobilised its UXO vessel Kamara.
