Prediction of Wave Pressure and Loads on Actual Ships by the Enhanced Unified Theory

To establish a new practical calculation method in place of the conventional strip method, performance of the enhanced unified theory is investigated through the comparison of computed results with a large number of experiments conducted with VLCC tanker and container ship models. In this paper, compared are the ship motions, the pressure distribution, and the wave loads. The enhanced unified theory is essentially based on 2-D computations but takes account of 3-D and forward-speed effects. Furthermore the effects of wave diffraction from the bow part near the waterline are taken into account in a rational way. Despite these theoretical improvements, the results of comparison for the wave loads are not so good as expected. Since the pressure and wave loads are strongly influenced by the accuracy of ship motions, more improvement is needed for precise prediction of the ship motions particularly near the resonance of heave, roll, and pitch.
