Renewable Energy Sources play a central role in the fight against climate change, as they represent one of the most important paradigms on which a renovated and sustainable society should be built. Among them, offshore wind energy is growing in popularity, as it represents a great opportunity to efficiently harness the vast potential of wind energy at sea. In particular, floating offshore wind turbines (FOWT) are the only viable solution at higher bathymetry and thus they could open the possibility for a much wider installation worldwide. FOWTs are stabilized thanks to the structure on which they are built, moored to the seabed.
