In the 2011 Tohoku earthquake and tsunami, a lot of sea disasters of ships moored along terminal inside harbor basins occurred. In order to make a countermeasure for the disasters, and investigate the mechanism of the ship’s behavior, it is required to reproduce the motions of ship precisely, and the key issue is how to express and estimate the tsunami wave force. In this paper, a physical model test on dynamic behavior of a moored ship which is a modeled 90,000DWT class coal carrier affected by the disaster, has been conducted in two-dimensional water tank during a tsunami bore. The surface elevation, current, motions and mooring loads of the ship have been measured in a following sea. The reproduction of the ship’s behavior and estimation of the tsunami wave force have also been done by using a numerical simulation method of ship motions and mooring loads.
