Abstract: Several offshore wind farms are planned for installation in the Gulf of Bothnia, Baltic Sea. As the sea is at least partially frozen every year, wind turbine foundations must be designed accordingly. However, the related forces and ice conditions now and decades into the future remain unknown. Here, we present a working technical concept by combining modelling in continuum mechanics based large scale sea ice dynamics model and discrete element model that can be used to simulate interaction between drifting pack ice and offshore structures.
