A method for forming the basis of a tower-like structure
The culmination of the innovation is the development of a wind power method suitable for ice conditions, which was granted a patent in 2016. An installation method, a steel-reinforced and pre-stressed concrete base has been developed for the offshore wind farm. The good properties of concrete and steel can be utilized cost-effectively and achieve a service life of up to 70 years. The hybrid base is suitable for a 4… 10 MW turbine and a depth of 8… 35 m. Large ice loads are also included in the design input data. The concrete-based lighthouses in the Gulf of Bothnia demonstrate the functionality of the concept well.
