The Course Will tackle the main challenges in state of the art modelling of floating offshore wind turbines, focusing on the main subsystems, such as moorings, substructure, turbine.

.

Prof. Maurizio Collu - Naval Architecture, Ocean and Marine Engineering , Glasgow, Scotland The following topics will be addressed: Hydrodynamic loads on the substructure o Hydrostatics o Wave loading regime: Diffraction parameter and Keulegan-Carpenter number o Loads on large volume bodies: potential approach (radiation and diffraction)o Loads on small volume bodies: Morison Equation Equations of motion: frequency approach Environmental loads in the time domain: Wind loading on fixed bodies and on rotor (Actuator Disk theory, Blade Element-Momentum theory, correction to the theory) o Hydrodynamics loads in time domain: Cummins equation o Mooring forces o Soil forces Offshore wind turbine aero-hydro-servo-elastic analysis in the time domain: State of the art o Free decay, wave only (regular/irregular), wind and wave o Postprocessing: basic statistics, FFT, (pseudo) RAO
