Abstract The models of SEVAN 650 and GVA 7500 were established in Pro/E software. The proposed models were imported into the Hydrodynamic Diffraction module of ANSYS Workbench software to calculate the response amplitude operators of each platform in storm environment of South China Sea. The hydrodynamic characteristics of the two platforms in the storm environment were compared by the characteristic curves of heave, roll and pitch. The results show that SEVAN 650 has better crude oil storage capacity and deck variable load bearing capacity than those of GVA 7500, which indicates that SEVAN 650 has better anti-dumping capacity than that of GVA 7500 in storm environment. However, the heave response amplitude operator of SEVAN 650 in storm environment should be further reduced.
