Abstract
The objective of present paper are to establish the practical numerical analysis system for responses of motion and mooring forces on a floating structure induced by Tsunami and to clarify the characteristics of responses on a floating body in Tsunami. In the present analysis system, the initial Tsunami profile is evaluated by applying Mansinha-Smylie's Method and propagated Tsunami profiles are calculated by the linear long wave theory and also the Tsunami exciting forces on a floating body are computed by the numerical wave tank based on VOF method and then the motions and mooring tether forces due to Tsunami are predicted by using the convolution integral method. The usefulness of the present system is confirmed by comparing with the experimental results of Tsunami exciting forces on the floating body.
