PAPENDRECHT, the Netherlands – TenneT has awarded Boskalis the contract for laying of the Hollandse Kust West Beta export cable in the Dutch North Sea.
The scope comprises installation of two 65-km (40.4-mi) long export cables that will connect the 700-MW Hollandse Kust West Beta offshore wind farm to TenneT’s onshore grid in the Netherlands.
In addition, Boskalis will install a 9-km (5.6-mi) 66-kV interconnector cable between the Hollandse Kust West Alpha and Hollandse Kust West Beta offshore substations.
Boskalis will execute the work in partnership with Orient Cables, which will design and supply the high-voltage cable system. The two 220-kV AC cable circuits will come ashore close to the onshore HV substation at Wijk aan Zee.
As part of the program, Boskalis will also remove unexploded ordnance from the seabed, also performing geotechnical and geophysical surveys, beach and seabed preparation works and laying and burial of the cables.
Hollandse Kust West Beta should start operating in 2025.
