Iv

Iv was engaged by the GE‑Seatrium Consortium (GSC) to provide design and engineering services for TenneT’s 2 GW offshore grid connection programme in the Dutch North Sea, covering the IJmuiden Ver Beta, IJmuiden Ver Gamma and Nederwiek Beta platforms. For these next‑generation 525 kV HVDC assets, Iv’s scope included detailed engineering of both the topsides and the jacket substructures, translating the standardised 2 GW concept into buildable, class- and offshore-ready designs. For the IJmuiden Ver Gamma connection that will serve the IJmuiden Ver Gamma-A and IJmuiden Ver Gamma-B wind farm sites, this work encompassed detailed structural and interface engineering of the jacket foundation and associated topside integration. Iv also supported joint procurement of equipment and auxiliary systems, requiring coordination across multiple partners and suppliers and ensuring the design remained practical for fabrication, transport and offshore installation. Iv stated that the first platform in the series, IJmuiden Ver Beta, functioned as the blueprint for subsequent platforms, implying design replication and optimisation across the programme. The engineering focus was described as improving structural integrity, maintainability and future-proof operation, while supporting lowest‑cost offshore transmission solutions consistent with TenneT’s large-scale offshore electrification objectives.
