PARAMETRIC SIMULATION OF SEMI-SWATH SHIP RUNNING IN FOLLOWING REGULAR WAVES

摘要

Ship motion in sea wave normally moves in a dynamic of periodic surging motions. In following sea waves, the ship may have some conditions such as; the ship is trapped in between the crest of waves; the ship overtakes the waves or the ship along with the wave’s celerity. In a high Froude number, the high steepness waves can lead the ship in to surf-ride condition. Even the ship can experience acceleration to the trough of wave and cause the bow diving happens. The dynamic stability properties in relation to the ship behaviour such as, surf-riding and bow-diving were very important issue of safety in the sea.
