Abstract

Recently, it has been announced as a warning that the Tokai, Nankai and Tounankai earthquakes will be anticipated to surely occur within next 30 years. These earthquakes involve large scaled tsunami. When the tsunami attacks ships moored inside harbor basin, the motions might attain large movements that exceed the safe mooring conditions due to the surface elevation, the currents and a resonance effect with natural periods of sway or surge of the moored ships based on our previous study which proposed a numerical simulation procedure of moored ship motions induced by tsunami. In this paper using the simulation method, we investigate characteristics of the moored ship motions and the mooring loads, affected by berth location, ship kind, ship condition, and mooring system.
