DEME has won a contract covering the transport and installation of 69 wind turbines for phase one of the Zeevonk offshore wind farm in the Dutch North Sea, the company announced on Wednesday, October 14.
The company said the contract falls within its €50 million–€150 million value category. Phase one has a planned installed capacity of approximately one GW.
DEME will use its jack-up vessel Norse Energi for offshore transport and installation during the campaign. Mobilisation is expected in 2028, with offshore operations following shortly afterwards and completion expected in 2029. A final investment decision is still required for the project.
The site lies between 63 and 84 kilometres off Bergen aan Zee. Zeevonk is jointly owned by Vattenfall and Copenhagen Infrastructure Partners (CIP).
The award follows DEME's July contract for the phase's 69 monopile foundations. That contract falls within the company's €150 million–€300 million category and will see the floating installation vessel Orion handle the monopiles.
Boskalis separately secured the phase-one inter-array cable contract on October 1. It covers approximately 149 kilometres of 66 kV cables, which the cable-laying vessel BOKA Ocean is set to install in 2029.
Zeevonk covers 650 square kilometres. The project’s second phase is planned for 2032 and will add one GW of wind capacity and 500 MW of system-integration capacity.
CIMC Raffles delivered Norse Energi in January. DEME said she can install turbines whose rotor diameters exceed 300 metres at water depths of up to 70 metres.
