One Consideration to the Mooring Harborage of Aframax Tanker during the 2011 off the Pacific Coast of Tohoku Earthquake Tsunami

Abstract

The 2011 off the Pacific Coast of Tohoku Earthquake Tsunami at 14:46 JST, 11 March 2011 affected the large areas of eastern and northern part of Japan, and also many sea disasters against vessels moored along the terminals inside the harbor basins were occurred. However, there was a successful example of safe mooring harborage of an Aframax tanker during the tsunami. In order to investigate the tanker behavior and find out the causes to achieve the safe harborage, we have conducted a hearing investigation to the crews, and tried to reproduce the moored tanker behavior during the tsunami by the numerical simulation methods on ship motions and tsunami.
