A Fundamental Study on Tsunami Damage Control of Moored Vessels Using the MPS Method

When the tsunami attacks in harbors, the vessels moored at the wharf may be unable to be evacuated. In such a case, damages such as, breaking the mooring tethers, grounding on a wharf, drift to land areas and the collision with buildings are assumed. This present paper describes the tsunami simulation and the motion analysis of vessel moored at the wharf using the MPS Method. In this research, the 3D-MPS method is applied. The chart of mooring tethers break was created. The wave height of tsunami and the relation of the break of the mooring tethers were shown by the chart of mooring tethers break. The chart was created about the influence of number of mooring tethers, diameter of mooring tethers and mooring system to the break of mooring tethers.Copyright © 2013 by ASME
