Boskalis has won a contract from 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 company describes the contract value as "sizable" without disclosing an amount. Boskalis wins inter-array cable installation contract for Zeevonk Offshore Wind Farm phase 1 in the Netherlands.

A scope of 149 km of 66 kV cables

The contract covers the transport and installation of approximately 149 kilometers of 66 kV inter-array cables, which will connect 69 wind turbines within the wind farm. It also includes cable testing and termination, as well as the installation of cable protection systems. Boskalis will also carry out survey activities and seabed intervention works.

For the latter, the company says it will deploy one of its subsea rock installation vessels. The cables will be shipped from the manufacturing facility in Eemshaven, the Netherlands, to the wind farm. The transport and the offshore installation campaign are to be carried out with the cable-laying vessel BOKA Ocean.

Offshore installation planned for 2029

According to Boskalis, engineering activities are expected to begin shortly. Offshore installation is currently planned for 2029. Phase 1 is scheduled to reach commercial operation in the same year.

The Zeevonk Offshore Wind Farm is located approximately 45 nautical miles northwest of IJmuiden, the Netherlands. Once completed, it will have a total installed capacity of approximately 2 gigawatts (GW), which would make it one of the largest offshore renewable energy developments in the country. The project will be developed in two phases of approximately 1 GW each, and the Boskalis scope relates to the first.

Boskalis says its strategy aims to leverage macro-economic factors that drive global demand: expansion of the global economy, rising energy consumption, global population growth and the challenges linked to climate change. The group ties this project to the development of renewable energy generation in response to climate change and increasing energy consumption.
