Abstract
Wave loads predicted by the extended SHIPMO computer program were compared with experimental data in an attempt to assess the range of validity and to estimate the uncertainty of the predictions. In general, the agreement between theory and experiment was good for the vertical bending moment, but fair to poor for the horizontal bending moment. The predicted torsional moment was found to be in gross disagreement with the measured values in terms of both magnitude and trend. It was not possible to find any correlation of the pattern of the discrepancy between theory and experiment with the principal design characteristics, such as hull form or weight distribution. The present comparison shows that the prediction of ship motions in oblique seas needs to be further improved. TRUNCATED
