RWE and TotalEnergies have chosen the port of Eemshaven in Groningen, Netherlands, as the base for turbine assembly and construction work for their joint offshore wind project OranjeWind in the Dutch North Sea. To this end, the OranjeWind joint venture has signed an agreement with Buss Terminal Eemshaven.
Construction activities at the offshore wind site will start in early 2026. Buss Terminal Eemshaven will facilitate the offloading, storage, handling, and pre-assembly of major turbine components and inter-array cabling for the OranjeWind wind farm. The monopile foundations will be transported directly to the offshore installation site from Sif’s production facility at the Port of Rotterdam. Turbine installation at the OranjeWind offshore site, approximately 278 km from Eemshaven, is scheduled to start in early 2027, with commissioning expected to be fully completed by the end of 2027.
Turbine manufacturer Vestas will provide 53 of their 15 MW turbines to OranjeWind, while Sif will manufacture monopiles and secondary steel components. Jan De Nul Group has been contracted for various transportation and installation activities for foundations and turbines. TKF will manufacture and supply the inter-array cables, with DEME handling the transportation and installation of these cables. DEME is also contracted to install the secondary steel components for the foundations. Grid operator TenneT will facilitate the offshore grid connection, linking the inter-array cables to its offshore substation, from which export cables will feed into the onshore high-voltage substation in Wijk aan Zee. Upon completion, Vestas will service the wind turbines for five years under a service agreement, followed by a long-term operational support agreement.
