Sif Group

Sif Group was contracted to supply the monopile foundations for the Hollandse Kust Zuid (HKZ) offshore wind farm in the Dutch North Sea. This scope related to the manufacture and supply of the steel monopile foundation structures used to support the project’s wind turbines across the four-site HKZ 1–4 development. The project is a large-scale, subsidy-free offshore wind farm built in water depths broadly in the high-teens to high-twenties of metres, and its turbine support structures were based on monopile foundations. As the monopile foundation supplier, Sif Group’s role was situated in the construction supply chain, providing the primary steel foundation components required ahead of offshore transport and installation. While the cited source did not provide detailed sub-scope split (e.g., transition pieces versus primary monopile structures) or manufacturing location, it explicitly identified Sif Group as the contracted monopile foundation supplier for HKZ. The foundation supply package supported installation of the full wind farm build-out. No contract value, currency, or precise contract award date was provided in the referenced project description. The supply work nevertheless represented a core balance-of-plant manufacturing scope, aligned with fabrication and delivery of monopile foundations for the project’s turbine count.
