Outline of Final Research Achievements

An optimization of tsunami calculation has been carried out based on the information of the Great East Japan Earthquake for the improvement of rapidity. In addition that, validity of the CFD estimation method of hydrodynamic forces and moment acting on a hull in the unsteady complex tsunami flow field is confirmed in the comparison to experimental results. Moreover, an estimation method of ship complex behavior in mooring condition at a wharf in the condition of tsunami attack.
As the results, a ship-tsunami linked multiple complex behavior analysis system that can solve and evaluate the complex ship motions has been established, and various kinds of evaluation for the tsunami disaster prevention, reduction, and management relating ships in the bay and coastal area are ready to proceed.
