Tor Anders Nygaard - Offshore wind energy; technology overview and scientific challenges

The revised EU Renewable Energy Directive, adopted in 2023, sets an EU target for renewables of at least 42.5%, which will require that the installed wind capacity grows to more than 500 GW by 2030. A major part of this target is offshore wind energy, with bottom-fixed substructures in water depths up to about 70m, and floating platforms for deeper waters. Due to the coupling between loads, motions and control system, analysis of floating wind turbines is usually carried out with time-domain aero-servo-hydro-elastic simulation tools. The seminar will give a technology overview, state-of-the-art in modelling, and mention some of the scientific challenges currently being addressed in the wind energy community.
