A Study on Damage Control of Vessels Moored to The Wharf in Tsunamis (Part 2) -About the Validity of Floating Pier Mooring-

津波来襲時における岸壁に係留された船舶の防災・減災対策に関する研究(その2)-浮桟橋係留の有効性について-

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 three dimensional (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.
