Abstract

In order to make a countermeasure for a sea disaster such as the 2011 Tohoku earthquake and tsunami, it is required to reproduce the motions of ship precisely and practically, and the key issue is how to express the tsunami wave forces. Several physical model tests on ship’s behavior and tsunami wave forces, which was a modeled 90,000DWT class coal carrier affected by the Tohoku disaster, had been conducted in two-dimensional water tank during a tsunami bore. The surface elevation, current, motions, mooring loads and tsunami wave forces of the ship had been measured in a following sea. In this paper, a systematic approach to reproducing the ship motions, mooring loads and tsunami wave forces has been investigated by using a numerical simulation method of ship motions.
