Using the wave forces obtained from ANSYS AQWA, the structural analysis of the gravity substructure for 5MW offshore wind turbines is carried out through ANSY Mechanical. Moreover, the comparison of natural frequency between the wind turbine and the gravity substructure is made to investigate the resonance. It is found that the suggested gravity substructure can be an effective substructure for 5MW offshore wind turbines.
