It is extremely important to estimate damage when tsunami disaster for vessels in order to prevent or reduce damage of vessels. Overthrow of vessels and grounding on a wharf concern on when vessels are moored in harbors. This paper reproduces behaviors of vessels moored near wharfs due to tsunamis by using the moving particle semiimplicit method (MPS). The two dimensional MPS method program code has been developed and the validity of the program is proven by comparing with model test.
Solitary waves have been applied to simulated tsunamis and the model experiments. A box like model is used to a floating structure in numerical simulations using the two dimensional MPS method. The present numerical results are compared with the experimental results and the applicability of the MPS method is discussed. In addition, the mooring force was considered. The behavior of grounding on a wharf of moored vessel is examined. As a result, the usefulness of this numerical technique is confirmed.
