DEME to Transport and Install 69 Turbines on Zeevonk Offshore Wind Farm Phase 1

DEME's next-generation jack-up vessel, Norse Energi, has been tasked with the transportation and installation of 69 wind turbines at the Zeevonk offshore wind farm in the Netherlands.

Norse Energi Assigned to Turbine Installation Campaign in the Dutch North Sea

The Belgian marine engineering group announced the contract, which covers phase 1 of the project, a development with a total installed capacity of approximately 1 GW.

The vessel was purpose-built for transporting and installing offshore wind turbines, and its assignment to Zeevonk continues the build-out of DEME's offshore installation capabilities in the Dutch North Sea. Under the contract, Norse Energi will carry the 69 turbines to the site and install them during phase 1 of the construction sequence.

Second Award Strengthens DEME's Scope at the Site

The turbine installation contract follows a substantial foundation installation contract that DEME secured for Zeevonk in July 2026, according to the company.

With both awards in hand, DEME's involvement now spans the primary structural elements of the wind farm's construction, covering the foundations as well as the turbines themselves.

The company's announcement notes that the newly signed contract gives it a key role in the offshore wind project, building on the momentum of the earlier foundation award.

Together, the two contracts create a continuous work stream at the site for the Belgian group, with attention now turning to the mobilization of Norse Energi and the execution of the transportation and installation campaign.

Vattenfall and CIP Jointly Own the Approximately 1 GW Project

The Zeevonk offshore wind farm is jointly owned by Vattenfall, the Swedish energy company, and Copenhagen Infrastructure Partners through its Energy Investment Fund I.

Once completed, the project is expected to reach a total installed capacity of approximately 1 GW, placing it among the sizable offshore wind developments underway in the Dutch sector.

CIP is one of the world's largest dedicated investors in offshore wind and energy infrastructure, and its Energy Investment Fund I holds a joint ownership stake in Zeevonk alongside Vattenfall.

The wind farm is located in the Netherlands, where it will contribute to the country's expanding offshore wind portfolio. The construction sequence will rely on the coordination of heavy-lift and jack-up installation assets in the North Sea, spanning the foundation installation work under DEME's earlier contract and the turbine installation scope now awarded to the company.

A Substantial Single-Vessel Assignment for the Dutch Sector

DEME describes the contract as sizable, and the scope of 69 turbines for phase 1 represents one of the more substantial single-vessel installation assignments announced for the Dutch offshore wind sector.

The use of a next-generation jack-up vessel for the work reflects the scale of the installation task, with DEME's fleet designed to transport and install offshore wind turbines at sea. Norse Energi's deployment at Zeevonk adds to the vessel's role within DEME's offshore wind installation operations, and the assignment underscores the company's standing in the offshore wind installation market.

As the joint venture of Vattenfall and CIP advances the development toward its approximately 1 GW installed capacity target, phase 1 and its 69 turbines form part of the ongoing build-out of European offshore wind capacity, in which large-scale Dutch projects are being developed by consortia of energy companies and infrastructure investors.
