Roermond’s Sif will deliver the largest foundations the company has ever made to Dogger Bank’s wind farm off the UK coast.
These are the so-called monopiles, huge piles that are anchored to the bottom of the sea and on which the entire windmill is placed. They have a diameter of 8.6 meters, which, according to Sif, is about the maximum size the company can manufacture in its existing factories.
6 million households
Located between 130 and 190 kilometers off the British coast in the North Sea, Dogger Bank will become the world’s largest offshore wind farm, providing power to 6 million British households.
South dutch coast
Sif has now started the first production of the 95 monopiles for the first phase of Dogger Bank. In the third quarter, Sif was still building the last monopiles for the Hollandse Kust Zuid wind farm. Due to the time it took to convert the production lines for Dogger Bank A, production weakened a bit last quarter. Sif saw its order book grow to 450 kilotons, from 400 kilotons at the end of the first half of this year. These are final assignments and exclusive negotiations.
Even larger monopiles
Sif recorded a turnover of 332 million euros in the first nine months of this year, with an operating result of 28 million euros. The listed Sif is considering even larger monopiles with a diameter of 11.5 meters, a length of 120 meters and a weight of 2,500 tons. For this new generation of wind turbines, the production facility in Rotterdam will have to be expanded considerably and the one in Roermond will have to be adapted in order to be able to build such foundations by the end of 2024.
Sif aims for an annual production of 200 units. The company will make an investment decision on this in July next year. Sif is also considering the possibility of monopiles with a diameter of 15 meters.
