TenneT, in consortium with Orient Cables (NBO), has awarded Boskalis the Hollandse Kust West Beta export cable contract. The contract scope comprises the installation of two 65-kilometre-long export cables that will connect the planned Hollandse Kust West Beta 700 MW offshore wind farm to TenneT’s onshore grid in the Netherlands.
Furthermore, Boskalis will install a 9-kilometre-long 66 kV interconnector cable between the Hollandse Kust West Alpha and Hollandse Kust West Beta offshore substations. Boskalis will execute this contract in consortium with its partner NBO that will design and supply the high-voltage cable system. The two 220 kV AC cable circuits will come ashore near the existing onshore high voltage substation at Wijk aan Zee, the Netherlands.
Boskalis has not clarified the contract’s worth, but says is has a value of between EUR 50-150 million.
For this project, Boskalis will deliver an integrated solution of in-house services including the removal of unexploded ordnance from the seabed, geotechnical and geophysical surveys, beach and seabed preparation works and the laying and burial of the cables. The Hollandse Kust West Beta offshore windfarm is expected to enter service in 2025.
