Wind Energy – Gravity-based Foundations

Per Aarsleff has been awarded a contract with HOFOR, Greater Copenhagen Utility, on design, production and installation of the foundations for Aflandshage Offshore Wind Farm in the Øresund Strait, ten kilometres south of Amager.

The 26 foundations will be carried out as gravity-based foundations, and the concrete production will take place as prefabrication at Aarsleff’s factory in Swinoujscie in Poland.

Here, the foundations will be cast directly on barges which will then be transported to Aflandshage where the foundations will be installed on the seabed by means of a specialised vessel.

“Aarsleff was among the pioneers within establishment of offshore wind farms – and we have been a driver of development over the past 20 years. We see a great potential for wind farms which are carried out with gravity-based foundations, and we are pleased to contribute with solutions with more green energy,” says Jesper Kristian Jacobsen, CEO of Aarsleff.

The foundations will have a height of between 17 and 25 metres and a weight of up to approx. 4,000 tonnes. Each foundation will carry a wind turbine of a total height of 220 metres.

Design and planning will begin now, while the concrete production will begin mid-2024. The first offshore work, which is dredging and establishment of stone bed, will also be carried out mid-2024, and the installation of the foundations will take place in the first half of 2025. The work must be completed in the autumn of 2025.
