Abstract

Floating offshore wind turbines are envisaged to undergo a significant development in the near future, due to their advantages with respect to the onshore or nearshore counterparts, in terms of greater available wind power, reduction of the land occupation and minimization of the visual impact of the turbines. Although many numerical codes have been developed for the representation of the dynamic behaviour of such structures, few experimental data have been collected up to now. These data would be useful for the validation of the codes and to give practical indications for the design of floating offshore wind turbines. This paper reports some results based on experimental data collected during an at-sea experiment on a 1:30 model of the OC3-Hywind spar support for floating offshore wind turbines, in parked rotor conditions. The experiment was carried out at the Natural Ocean Engineering Laboratory (NOEL) of Reggio Calabria (Italy), between July 2015 and March 2016. Heave and yaw representative response spectra of the structure, obtained for local wind-generated waves, are shown, and the corresponding damping estimations are performed. The results obtained could be useful for design purposes and motivate further elaborations of the experimental data collected during the experiment, to be realized in the near future.
