Sif Group is a Netherlands-based manufacturer of offshore foundations for wind turbines and oil and gas platforms, with a history dating back to 1948. It specializes in monopile foundations, including XL sizes up to 11 meters in diameter, produced at two sites in the Netherlands: Roermond in Limburg and Maasvlakte 2 near Rotterdam. The company operates with a workforce in the hundreds and has been listed on Euronext Amsterdam since 2016. The firm serves the offshore energy sector by supplying foundations to wind-farm developers and related projects, including contracts for Bałtyk II and Bałtyk III with Equinor and Polenergia. In 2024, Sif partnered with Smulders Group to support the Hollandse Kust West Beta project by delivering jacket foundations and pin piles, illustrating active project execution collaboration. Ongoing investments to expand production capacity, notably in Rotterdam, reflect efforts to accommodate larger monopiles and broaden project scope.
