Hydrodynamic Investigation on Floating Offshore Wind Turbine Platform Integrated with Porous Shell

As the siting of wind turbines increasingly transitions from shallow water to offshore deep-water locations, improving platform stability floating is becoming a growing concern. By coupling porous shell commonly used in traditional marine structures, with FOWT (floating turbine platform), new spar-buoy was designed. A numerical model investigating effect aero-hydro-mooring system developed, and results motion response are compared OC3-Hywind spar. The two platforms simulated time-domain incident wave period varied range 5~22 s. exciting force added mass radiation damping spar demonstrate that amplitude decreases all three main freedoms (i.e., surge, heave pitch, etc.), among which motions most significantly attenuated. study shows shells achieve reduced responses feasible can be an innovative structure for development deep-sea turbines.
