| Research Abstract |
This study has been carried out for the investigation of minimization of ship disasters when tsunamis attach bay and coastal areas. First, basic ship navigation and mooring data were obtained by AIS(Automatic Identification System) for the evacuation analysis from the tsunami attack.
Then we developed ship simulation programs for ship evacuation from tsunami attack. It is found that most ships in Bisanseto area can evacuate safely to the shelter areas by use of the program.
Moreover, evacuation guidelines for an LNG ship, which is representative of a hazardous cargo carrier, were considered for the case of the ship entering the port. It is possible that the ship may encounter the first tsunami event in the case that the ship begins to evacuate from an inbound mooring direction. However, in the case where the ship is moored in the outbound direction and is oriented toward the open ocean, it is likely to overcome the potential threat of the first tsunami event.
In addition above, we have developed ship motion analysis programs suitable for inter moored and/or connected ships under tsunami attack external forces. Using this system it is possible to evaluate whether those moored ships can ensure the tsunami attack.
Above mentioned programs can evaluate several complex ship situations under tsumai attack
