Simulation program has been developed to simulate comprehensive ship responses in bi-directional irregular waves. Statistical analysis has been made on the simulated time history to have "theoretical distribution" of response amplitude. Model experiments corresponding to the simulation were set up using an elastic model of a bulk carrier in three kinds of loading condition, i,e, full loaded condition and two ballast conditions of the same displacement with different trim conditions. Comparisons were made between the simulation and the experiment on histograms of longitudinal bending moment and variations of significant values of the moments along the hull. Discussions cover effects of slamming and whipping to the bending moment and changes of responses to the loading conditions and effects of heading angle in the bi-directional waves.
