TKF announced it has signed an inter-array cable contract with Vattenfall and Copenhagen Infrastructure Partners (CIP) through its Energy Transition Fund for phase 1 of the Zeevonk offshore wind project. Under the contract, TKF will be responsible for the design, engineering, manufacturing, testing, supply- and project-management of the 66 kV inter-array cables, including the associated accessories.
Covering an area of 650 km², the Zeevonk project will be located in front of the Dutch North Sea coast, between 63 and 84 km away from the coastal town of Bergen aan Zee. The project is divided into two stages. Phase 1 delivers 1 GW of offshore wind by 2029. Phase 2 follows in 2032, adding another 1 GW of wind and 500 MW of system integration capacity. This includes the development of an electrolyser in the Port of Rotterdam to enable green hydrogen production. Zeevonk is co-owned by Vattenfall and CIP.
The scope of the contract places strong emphasis on sustainable cable design, an area in which TKF plays a leading role through its advanced connectivity solutions. The cables will be manufactured at TKF’s state‑of‑the‑art facility in Eemshaven in The Netherlands.
The inter-array cables feature a distinctly bitumen free sustainable design, incorporating low‑emission aluminium, recyled steel, recyled copper. These material choices are expected to further reduce the cables’ emissions footprint and contribute to a lower environmental impact across the full product life cycle. These solutions help reduce the carbon footprint of the cables while increasing their circular content.
The incorporation of these circularity measures supported Zeevonk’s competitive position in the tender process, enabling the project to meet the required sustainability and circularity criteria through multiple design solutions.
TKF designs, manufactures and delivers innovative and sustainable connectivity solutions that enable safe and reliable energy and data connections. TKF is headquartered in the Netherlands.
