Abstract
<jats:p>In order to further investigate the impact of the hybrid energy system combining a floating offshore wind turbine (FOWT) with wave energy converters (WEC) on the platform’s dynamic response, this study builds upon existing research and installs 4 point-absorbers in the moon-pool type opening of the barge type platform. First, the frequency-domain analysis is conducted to explore the effect of wave energy floaters on the moon pool’s heave resonance and the platform’s response amplitude (RAO). Then, a time-domain analysis is performed to examine the dynamic response of the coupled platform in a variety of wind and wave conditions in the South China Sea (S4 sea area), comparing it with the original platform without wave energy converters. The results show that the installation of wave energy converters in the moon pool effectively attenuates the first- and second-order heave resonances, and in typical South China Sea conditions, it reduces the dynamic responses of the platform in both heave and pitch directions, demonstrating the significant effect of wave energy converters in mitigating platform dynamic motions.</jats:p>
