Designation Method of Dynamic Intentional Grounding Zone in Coastal Region for Passenger Ship Refuge in Uncontrolled Marine Accident

Abstract

The ship evacuation system is being demanded to save both passenger and vessel by finding a safety route and region though the real-time analysis of vessel condition and maritime metrological environment when emergency situations occur such as fire, flooding, and broken balance. Grounding zone is important to prevent sinking of vessels and to minimize injured and casualties during accident by beaching ships on a safety zone as well as to avoid damage of vessels during normal shipping. In this study, we introduce a designation method of the dynamic intentional grounding zone (DIGO) in place around passenger ship for effective emergency evacuation in uncontrolled marine accident. The research area is the southwest coastal region of Korea including Mokpo and Jindo Island. In this region, there are many passenger ships between inland and islands, and it should be particularly careful in navigating because of many islands and reefs. DIGO is automatically calculated in three-dimensional space by combining hydrodynamic numerical model, shipping information (main route, position, draft, etc.), and marine environments such as water depth and sediments. The type of marine sediments in safety zone was defined as sand, silt, and clay in order to minimize the damage of vessel and passenger during the beaching on a zone. The water depth data with a resolution of 20 ~ 30 m was used to present more precise results, and the draft inf as fire, flooding, and broken balance.
