EXPERIMENTAL STUDY OF WAVE PRESSURE ON VLCC RUNNING IN SHORT WAVES

A free-running experiment of a VLCC ship model was carried out in short regular waves. The wave length and the heading angle were varied in the range of 0.2 less than or equal /L less than or equal 1.5 and 0o less than or equal less than or equal 180o respectively. The ship motion, vertical and lateral bending moment at midship, relative water level and wave pressure were measured. Among them, wave pressure on the side wall near the load water line was the particular interest of this experiment. The first harmonics of the measured data were plotted with calculations of the strip method. Two strip methods were used to compare accuracy; the first a so called new strip method (NSM) and the second an improves NSM developed by the authors. The solution method for the diffraction problem is developed to satisfy the exact body surface boundary condition. The plots of the measured wave pressure with the calculated value show that the accuracy of NSM is poor when
