Pragmatic, committed and ready for tomorrow

At Sif, we’ve been building trust, craftsmanship and progress since 1948. What started with pressure vessels has evolved into complete foundations for offshore wind. From our sites in Roermond and Maasvlakte 2, we contribute daily to the energy transition. In line with our growth and ambitions, we’ve been listed on the stock exchange since 2016.

Since 2002, we’ve produced over 2,600 monopiles and contracted 2,900. These support nearly 55 offshore wind projects, mainly in Europe. As a result, we’ve contributed to 35–40% of the market through 2024. Our foundations now support more than 22.7 GW of offshore wind energy.
