In the present study, damping model used for vibration response analysis of large ship structures is focused on. At first, an exciter test of VLCC was carried out in order to acquire a high resolution frequency response function. Then experimental modal analysis was carried out to identify the modal damping ratios. Obtained modal damping ratios show large discrepancy from conventional damping models. Therefore we proposed a practical damping model for the actual ship and performed the vibration response analysis using them. Future works were extracted based on the comparison of the numerical results with measured response of the ship structure.
