Boskalis Installing Final Hollandse Kust West Beta Export Cable

Grid Connection

June 21, 2024, by Adnan Memija

Boskalis’ cable-laying vessel Giant 7 has commenced with the installation of the second and final nearshore export cable for TenneT’s 700 MW Hollandse Kust (west Beta) project in the Netherlands.

Following the successful installation of the first cable by Boskalis’ Giant 7 barge, work on the second cable is now in progress.

Boskalis’ cable-laying vessel, assisted by the specialized burial sledge tool BSSIII, is poised to repeat the operation of delivering and connecting the second cable to the shore.

Two 65-kilometre-long 220 kV export cables are needed to connect the offshore wind farm to the onshore power grid. About four kilometres offshore, Boskalis’ cable-laying vessel Ndurance will take over the installation of the export cable.

The trenches for this export cable in the seabed are dredged by the company’s trailing suction hopper dredger Gateway.

Following the installation of the export cables, Boskalis will install a 9-kilometre-long 66 kV interconnector cable between the TenneT projects Hollandse Kust (west Alpha) and Hollandse Kust (west Beta) offshore connector platforms.

In 2022, Boskalis and its consortium partner were awarded a contract to connect the 700 MW offshore platform to TenneT’s onshore grid in the Netherlands.

In May 2024, Heerema Marine Contractors’ crane vessel Sleipnir installed the 49-metre-high jacket foundation for Hollandse Kust (west Beta) some 53 kilometres off the coast of Egmond aan Zee.
