The authors present the correction method of long-term wave frequency based on the observed data, by using the correlations between the observed and measured wave data. They have investigated how the accuracy of the long-term prediction results of the ship response is affected with the observation error of wave data. It was concluded that, (a) The long-term prediction results of hydrodynamic pressure on the water line and bilge based on observed wave frequency are somewhat smaller than those based on the corrected wave frequency. There is no significant difference between the long-term prediction results of hydrodynamic pressure on the keel centre line based on the observed wave frequency and those based on the corrected wave frequency. (b) There is no significant difference between the long-term prediction results of vertical wave shearing force based on the observed wave frequency and those based on the corrected wave frequency. And the similar results are obtained for the vertical wave bending moment. (c) The long-term prediction method based on the observed wave frequency would be acculate enough for practicl purpose.
