Boskalis connects all export cables and platforms for offshore wind farm in Netherlands

Boskalis, an offshore construction company, has completed the connection of all export cables and platforms for the offshore wind farm being developed by RWE in the Dutch North Sea.

Off the coast of the Netherlands, Boskalis connected all the export cables the company recently installed for the shore connection that TenneT is providing for RWE’s offshore wind farm.

Furthermore, the 66 kV interconnector cable between Hollandse Kust West Beta and Hollandse Kust West Alpha grid connection projects was installed and pulled into both platforms.

For the work, Boskalis deployed its cable-laying vessels, Giant 7 and Ndurance, which were assisted by the company’s supply vessel Kamara.

At the end of last month, a consortium comprising Boskalis and Orient Cables (NBOS) completed the pull-in and burial of the second export cable for TenneT’s Hollandse Kust West Beta offshore grid connection at the landfall location in Velsen-Noord, the Netherlands.

The 700 MW grid connection will link RWE’s OranjeWind offshore wind farm to the national grid. Currently, Boskalis’ trenching support vessel, Ndeavor, is still active at the offshore wind farm site burying the installed cables in the seabed, said the company.

Later this year, the firm’s subsea rock installation vessel, Rockpiper, will join the project to cover the export cable with rock at various points where it intersects with other infrastructure.

RWE and the Dutch transmission system operator (TSO) TenneT signed an offshore grid connection agreement for the new offshore wind farm in September 2023.

Recently, RWE and TotalEnergies entered into an agreement under which TotalEnergies will acquire a 50% stake in the OranjeWind offshore wind farm. TotalEnergies said it would use its share of electricity from the project to produce green hydrogen.
