Waves Group is providing MWS services for all phases of the project which includes, the installation of foundations, turbines, and array cables.
The HKZ Alpha export cables and transformer station jacket as part of the TenneT scope of work have already been installed. The work on the HKZ Beta cables and transformer stations is expected to start next year.
Waves Group’s contract commenced in Q2 2020 and will continue through the turbine installation phase to Q2 2023.
Hollandse Kust Zuid is located between 18-36 kilometres off the Dutch west coast.

Once fully operational in 2023, Hollandse Kust Zuid will become the largest offshore wind farm in the world.
