Boskalis wins cable contract for Zeevonk wind farm
The contract covers 149 kilometres of cable for 69 turbines in the first phase of the offshore wind farm.
Boskalis has been awarded a contract to transport and install cables in the first phase of the Zeevonk wind farm in the North Sea. The company describes the order as substantial; by its definition, that means a value of €50 million to €150 million.
The cables will connect the 69 wind turbines in phase one to TenneT’s offshore high-voltage substation. Boskalis will be responsible for approximately 149 kilometres of 66-kilovolt inter-array cables, testing and connecting them, and installing protective layers of rock on the seabed.
The transport of the cables will begin at the production site in Eemshaven. To lay them at sea, Boskalis will deploy, among other vessels, the cable-laying ship BOKA Ocean. A vessel for seabed work will also be used. Technical preparations are expected to begin shortly; offshore installation is scheduled for 2029.
Zeevonk is a joint project by Vattenfall and Copenhagen Infrastructure Partners. The wind farm is located in the Dutch part of the North Sea, north-west of IJmuiden. The project is being developed in two phases. Phase one is expected to provide approximately 1 gigawatt of wind capacity; the total development will amount to around 2 gigawatts.
The cable contract is the next step in the chain surrounding the wind farm. Contracts have previously been announced for, among other things, the installation of the foundations. For Dutch maritime service providers, the project means work on ships, cables, foundations, surveys and maintenance.
At the same time, the order is no guarantee that all project components will be carried out without delay. Vattenfall and CIP say that Zeevonk remains subject to a final investment decision. The 2029 schedule is therefore a project target, not an achieved date.
The scale of the project makes the contract relevant to the Dutch offshore wind sector. The development requires not only turbines, but also grid connections, cable infrastructure, shipping capacity and seabed work. These components partly determine whether the electricity generated will actually become available.
For Boskalis, the order is commercially interesting because it fits with its maritime infrastructure and offshore energy activities. The company has not disclosed the precise margin, payment terms or effects on revenue. The announcement therefore says something about the order book, but not yet about the profitability of the contract.
