The foundation of offshore wind energy
At Sif, we build the foundation for the energy transition.
With over 75 years of craftsmanship, we deliver reliable offshore foundation solutions that meet the highest quality standards.
We manufacture monopiles, transition pieces, TP-less monopiles, pin piles and jacket legs. Each product is unique and tailor-made for wind farm developers who demand quality and dependable delivery.
In 2024, we commissioned our fully upgraded production line at Maasvlakte 2. This has doubled our production capacity to 500,000 tonnes of steel per year. Bigger, more efficient, more sustainable – and ready for the next generation of offshore wind farms.
In addition to our products, we offer support through marshalling & logistics and value engineering: our services ensure efficient, safe and carefully planned project execution.
With our combined expertise in manufacturing, engineering and logistics, we offer a complete offshore foundation solution – from initial design to final lift at the quayside.
For every customer request, we listen critically and constructively. We ask the right questions and help find the best solution at a fair price.
We offer complete solutions for the offshore wind sector – from design and production to corrosion protection and logistics. We even consider dismantling and recycling.
We closely monitor market developments. This allows us to respond to changing needs with product and process innovations.
