漁船と大型船の衝突海難に関わるデータベースの構築および分析

抄録

Most marine accidents related to vessels are caused by human errors, such as mis-perception, mis-judgment and mis-operation in functional systems, which are contributing to collisions.
The risk assessment for the collisions between fishing vessels and cargo vessels is carried out in accordance with the guidelines for FSA (Formal Safety Assessment) approved by IMO due to their high occurance frequency and enormous damages. The records of adjudiction of marine accident inquiry are analyzed by VTA and the marine casualty database is constructed focused on human factors related to the cognition and decisionmaking process at the crossing situation. Risk Control Options (RCOs) are proposed based on the database analysis and its effciencies have been investigated considering the impact to the conition and decisionmaking factors.
