Royal Boskalis in consortium with TKF Subsea Solutions will supply and install about 140 kilometers of inter-array cables for the Gennaker Offshore Wind Farm (OWF) in the German Baltic Sea. Boskalis’ cable-laying vessel BOKA Ocean will install the cables as of the end of 2027.
The contract was signed recently with OWP Gennaker GmbH, as developed by Skyborn Renewables.
As part of the scope, Boskalis and TKF will deliver the complete 66 kilovolt inter-array cable system connecting the future 63 wind turbine generators in the OWF. The cables will be manufactured in the Netherlands by TKF. The contract is said to represent a value of between EUR 50-150 million.

Already at work at Gennaker OWF
Boskalis is already active on the Gennaker OWF through its subsidiary Heinrich Hirdes EOD Services GmbH, which is conducting an identification and clearance campaign for unexploded ordnance (UXO) within the OWF, for which it has mobilised its dedicated UXO vessel Kamara.
With a planned capacity of 976.5 MW, the Gennaker OWF will become the largest offshore wind farm in the German Baltic Sea, supplying about one million households with clean energy. Commissioning of the OWF is planned for 2028.

BOKA Ocean
Boskalis acquired the BOKA Ocean, which was originally built in 2009, in 2023. The company subsequently converted the vessel from a pipe-laying vessel into a broadly deployable cable-laying vessel.
The DP2 vessel measures 133.6 metres and has a deadweight of 9867 tonnes. The vessel sails under the flag of the Bahamas and offers 2400 m2 in deck area. Its modular cable lay system has a turntable capacity of over 3500 tonnes.
