DEME has been awarded a contract in its €150 million to €300 million “substantial” category for foundation transport and installation work on phase 1 of the Zeevonk offshore wind project in the Netherlands.

The project will have an installed capacity of approximately 1 GW and is jointly owned by Vattenfall and Copenhagen Infrastructure Partners (CIP), with CIP participating through its Energy Investment Fund I.

DEME will provide intermediate monopile transport and marshalling services for primary and secondary steel. The scope also includes the transport and installation of 69 monopile foundations and the placement of a filter layer for scour protection.

Zeevonk is planned in the Dutch North Sea, between 63 km and 84 km from Bergen aan Zee. Offshore construction is scheduled to begin in 2028, subject to a final investment decision.

The foundation installation will involve several vessels from DEME’s fleet. Orion, a floating offshore transport and installation vessel, will install the monopiles. A jack-up offshore transport and installation vessel will handle secondary steel work, while a fallpipe rock transport and installation vessel will carry out the scour protection scope.

Zeevonk CEO Felix Würtenberger said the award was another step in the project’s development. Bas Nekeman, Business Unit Director Northern Europe at DEME, said the contract extends the company’s cooperation with Vattenfall and Copenhagen Infrastructure Partners.
