Experimental Study on Tsunami Wave Force of Moored Ship in Following Sea under Tsunami Bore

Abstract

In the 2011 Tohoku earthquake and tsunami, a lot of sea disasters of ships moored along terminal inside harbor basins occurred. In order to understand the behavior of ship, it is important to find out a method of the tsunami wave force of ship. In this paper, a physical model test on tsunami wave force of a ship, which is modeled as 90,000DWT class coal carrier affected by the disaster, has been conducted in two-dimensional water tank during a tsunami bore in following sea. The surface elevation, current, tsunami wave forces of the ship have been measured. The tsunami wave forces have been investigated, compared with those of mooring loads of the model ship in mooring.
