Boskalis has been awarded a contract by Zeevonk, the joint venture between Vattenfall and Copenhagen Infrastructure Partners, for the transport and offshore installation of the inter-array cable system for phase 1 of the Zeevonk Offshore Wind Farm in the Dutch North Sea. The contract represents a value that is considered to be sizable.

The contract scope includes the transport and installation of approximately 149 kilometers of 66 kV inter-array cables, connecting 69 wind turbines within the offshore wind farm, cable testing and termination activities, as well as the installation of the cable protection systems. The transport of the cable from the manufacturing facility in Eemshaven, the Netherlands, to the wind farm, along with the offshore installation campaign, is planned to be executed using Boskalis’ state-of-the-art cable-laying vessel BOKA Ocean. In addition, survey activities as well as seabed intervention works will be carried out. For the latter, Boskalis will deploy one of its subsea rock installation vessels. Engineering activities are expected to commence shortly, with offshore installation currently planned for 2029.

The Zeevonk Offshore Wind Farm is located approximately 45 nautical miles northwest of IJmuiden, the Netherlands. Upon completion, the wind farm will have a total installed capacity of approximately 2 gigawatts (GW), making it one of the largest offshore renewable energy developments in the Netherlands. The project will be developed in two phases of approximately 1 GW each. The Boskalis scope relates to phase 1, which has a planned commercial operation date in 2029.

A sizable contract refers to a contract with a value of EUR 50–150 million.
