Using the Irregular Waves based on Spectrum, the structural analysis of the hybrid substructure for offshore wind turbines is carried out through ANSY ASAS in time domain. The comparison of numerical results between P-M spectrum and JONSWAP spectrum is made to investigate the ultimate structural safety. It is found that the suggested hybrid substructure can be an effective substructure for offshore wind turbines.

Recently, research have been rapidly increased for performance of offshore wind turbine. In this study, static structural analysis was carried out for a structural performance of hybrid concrete sub-structure of offshore wind turbine under environmental loads.
