Fraunhofer-Iwes

Fraunhofer IWES was contracted by the Netherlands Enterprise Agency (RVO) to develop a fully Integrated Ground Model (IGM) for the Doordewind Wind Farm Zone (DDWWFZ) in the Dutch North Sea, located around 77 km offshore. The zone is planned to accommodate 4 GW of offshore wind capacity split into two 2 GW sites (Doordewind I and Doordewind II), with the first site expected to be auctioned in 2027 and commissioned around 2032. The IGM scope involves consolidating and interpreting site investigation deliverables (including seabed and subsurface geophysical datasets) into an integrated, quality-controlled ground model that can be used by RVO and future permit-tender participants. According to the sources, RVO’s intent is to use the resulting IGM to derisk development by improving understanding of near-surface geology and seabed conditions, and by informing upcoming geotechnical investigations and later engineering design activities (e.g., foundation and cable concepts). Fraunhofer IWES was to perform the IGM work in collaboration with Tetra Tech RPS Energy and Geowynd, with the combined deliverables feeding into published site-data packages intended to support robust bidder planning and costing for Doordewind I/II development.
