Coupled Dynamic Response of an Offshore Multi-Purpose Floating Structure Suitable for Wind and Wave Energy Exploitation

This paper presents the coupled analysis performed in frequency and time domain, considering a multi-purpose floating structure suitable for offshore wind wave energy source exploitation. The encompasses an array of hydrodynamically interacting Oscillating Water Column (OWC) devices, moored through tensioned tethers as Tension Leg Platform (TLP), supports 10 MW Wind Turbine (WT). is built to incorporate properly solutions diffraction pressure- motion-dependent radiation problems around structure, mooring lines characteristics, OWCs aerodynamics WT by accounting aerodynamic modelling rotor, elastic turbine components, namely blades, drive train, tower. Numerical results are obtained developed methods, presenting fundamental hydrodynamic properties platform, well ultimate fatigue loads at several locations on expected be imposed it over its lifetime. effect installation sites (i.e., environmental excitation) lifetime investigated comparing estimated various Mediterranean Sea North locations. Finally, OWC effect, due air pressure oscillation inside converters, discussed, highlighting significant influence hybrid system’s loading conditions.
