A wind Turbine is a technology that can convert wind energy into electrical energy by utilizing rotor rotation due to wind to make the generator work. Wind turbine technology has developed both onshore and offshore to overcome the global energy crisis. The wind speed in the offshore site is more stable than in the onshore site due to fewer obstacles. The offshore energy potential can be reached by using a semisubmersible floating offshore wind turbine that can operate above 60 m which is concluded as intermediate to deep water. However, the hydrodynamic wave load creates a force that can cause motion on the platform. The motion of the platform will affect the control system, the dynamic response of the turbine components, and also the generator performance. Response characteristics of offshore wind turbines in some period range of the ocean wave is a crucial parameter to be considered in the analysis. Structural dynamic analysis can be completed simultaneously based on hydro-aero-servo-elastic. Moreover, this study compares the dynamic response of a semisubmersible floating offshore wind turbine and an onshore-based wind turbine with the same capacity to identify the effect of wave loads on wind turbine performance. The amplification of turbine deflection along with the instability of power generation may occur when the natural period of wind turbine components meets the wave period.
