To study a collision problem between a floating body and an offshore structure, the influence of the fluid force acting on the floating body must be considered. The change in the characteristic of the collision phenomenon with the relative speed of collision were investigated in the last report. However, the floating body was assumed to move only in the horizontal direction and the pitching and the heaving motions were neglected. To consider their effects, a new method of analysis using Boundary Element Method is developed. The influence of these motions on the collision phenomenon for both elastic and elastic-plastic responses is examined by comparing with cases assuming only horizontal motion.
