Sif Netherlands B.V.

SIF was named as a supplier to Project Gemini for the monopile foundations used to support the wind turbines at the 600MW offshore wind farm in Dutch waters. The sources described this work as part of the foundation supply chain put in place under Van Oord’s EPC delivery strategy for Gemini. SIF’s scope related to manufacturing and supplying the monopile primary structures for the turbine foundations. These monopiles formed the main steel tubular piles driven into the seabed, providing the principal load-bearing support for the Siemens SWT-4.0-130 turbines installed at the two Gemini sites, ZeeEnergie and Buitengaats. The contract value and exact award date were not stated in the provided extracts. However, the award context placed SIF’s delivery within the construction-phase procurement of major components and subcontract packages that supported offshore installation activities from 2015 onward. This role record captures SIF’s contribution specifically as a foundation manufacturer for the monopile primary structures, with interfaces to other foundation scope elements (such as transition pieces and offshore installation) handled by other contractors within the Gemini supply chain.
