Sif is a pioneer in the field of offshore foundations. With 75 years of experience, technical ingenuity and the daily commitment of our craftsmen and women, Sif has acquired a leading position in the supply chain for offshore wind farms. Our main product, the monopile, is the most common and most economical solution for installing offshore wind turbines. By delivering quality on time, safely and within the agreed budget for years, we are co-determining the speed with which the energy transition can take place. We have proven this: Currently, there are 2,400 Sif foundations anchored in the seabed. We are proud of that, because they are crucial for achieving our objectives in the energy transition.

Global politics faces a huge challenge: the energy transition. Sif lays the foundation needed for this – literally and figuratively. Sif dares to lead the way and not only to propagate its mission and vision, but also to follow through with actions. 20.2 million households already receive power from offshore wind turbines that stand on our foundation. Sif's monopiles enable these turbines to supply power under all circumstances; And that while the wind can blow at a speed of 70 km/h and the waves can reach a height of 6 meters. The energy transition builds on Sif.

Product innovation

The reduction of costs of offshore wind energy is primarily driven by innovations and efficiency improvements.

The industry continues to find ways to increase the power generation of offshore wind farms. Currently, a generating capacity of 15 MW per turbine is close to reality. Sif tracks the latest developments in turbine technology closely and investigates exactly what effect this will have on size, manufacturability and cost of foundations.
