Research on the Dynamic Performance of a Novel Floating Offshore Wind Turbine Considering the Fully-Coupled-Effect of the System

Floating offshore wind turbines (FOWTs) still face many challenges in improving platform stability. A fully submersible FOWT with inclined side columns is designed to tackle the current technical bottleneck of platform, combining structural characteristics semi-submersible and Spar platform. An integrated numerical model established considering coupled effect, hydrodynamic performance novel FOWT, are compared analyzed under different wave incidence angles frequencies, as well blade tower dynamic response three FOWTs coupling effect wind, wave, current. The results show that floating can significantly optimize has a better recovery ability after being subjected external loads. reduce heave peak its corresponding frequency reducing possibility resonance. operation should ensure positive inflow far possible avoid excessive forces lateral direction. Both affected by rotor rotation vibration varying degrees, while mainly motion. This study suggests application concept feasible be an alternative exploitation deep water.
