COMPARISON OF MEASUREMENTS AND CALCULATIONS OF WAVE INDUCED VERTICAL BENDING MOMENTS IN SHIP MODELS

Wave-induced bending moments are calculated using a linear theory of ship motions and are compared with measurements on ship models. While the results show the generally good engineering accuracy of the linear theory, they indicate that its extent depends upon the block coefficient of the model and on model heading and speed. Measurements on similar ships at different laboratories compare differently with the calculations, and calculations with different computer codes yield dissimilar results when applied to the same ship. The conclusion is that the level of accuracy to be expected from the calculations cannot be better than the uncertainties involved in the calculations or measurements.
