MOTIONS AND HYDRODYNAMIC LOADS OF A SHIP ADVANCING IN OBLIQUE WAVES

An analytical technique developed to estimate the respone motions and loads of a vessel is presented and the results are correlated with those of model tests and other methods. The stripwise computation technique is applied to the following hydrodynamic problems: wave-excited and motion-indiced forces and moments, wave loads on cross sections, and hydrodynamic pressure and relative motion. Extensive correlation analyses between theory and experiment, including full-scale comparisons, have been carried out for basic motions and loads and a number of derived responses in the cases of barges, in deep and shallow sea environments. The study shows that the predictive capability of the technique presented here covers a variety of responses of diverse configurations of ships and ocean platforms, as well as estimation of shallow-water bottom effect. The predictions, however, are less accurate in the region of shorter waves and higher ship speeds.
