Type: article
Abstract: When the tsunami attacks in harbor, the vessels moored at a wharf may be unable to be evacuated. In this case, the flowing damages are assumed; breaking the mooring tether, grounding on a wharf, drifting to land areas and destroying buildings. As the measure which prevents these, increase mooring tethers, increase anchors and a floating pier is mentioned. This present paper focused on the floating pier and describes the tsunami simulation and the motion analysis of vessel moored at a floating pier using MPS method (Moving Particle Semi-implicit method).In this research, the 3D-MPS method is applied. Examination was carried out about mooring to effectiveness of the floating pier at the time of a disaster occurring. At the time of “The Great East Earthquake” that occurred on March 11, 2011, the case that a sightseeing ship moored at a floating pier was the safety was referred. The situation such as the outbreak of the earthquake and the attack of the tsunami was reproduced.
