해양위해도 통합 모니터링 시스템

Abstract

Even with the previous efforts to decrease major marine accidents, the number of marine accident was more or less the same. Consequently, many international organizations and governments recognized the importance of new risk-based approach to reduce marine accidents. Recently, risks are being considered during design phase in order to build safer ships. In some cases, safety is no longer a restriction applied to design but an objective to be achieved. However, risks cannot be entirely eliminated in design phase due to many restrictions applied such as cost and performance requirements. Therefore, remaining risks should be constantly assessed and managed during ship operation phase. In addition, extreme conditions such as high wave and strong wind may result in higher risk level than that considered in the design phase. This paper proposes an onboard ship risk monitoring system that can be used during ship operation to determine various risks associated with current situation. The system calculates risk index for each accident category and determine highly probable accident scenarios for the accident category with high risk level using integrated risk model which covers accident causes and consequences. A prototype of the proposed system has been implemented to be used in passenger vessels for collision and grounding accident.
