Quantitative Risk Assessment of Maritime Accident for Different Types in Korea

Most of the international trade in Korea is made by sea transportation using ships, and maritime accidents are not only harmful to people but also lead to negative ripple effects in terms of national competitiveness. However, there are not many theoretical studies on the risk of maritime accidents in Korea, and in particular, there is no criteria for assessing the risk of marine accidents. Therefore, in this study, we propose risk matrix using frequency and fatality to evaluate the risk by nine accident types using the ship accident data of the past 10 years. As a result of the analysis, it was found that the collision was the most dangerous both in frequency and fatality, and capsizing, sinking, death·injury were found to be relatively low in frequency but high in fatality. Fire explosion, stranding, and touching were found to be relatively low compared to other types of accidents, while engine failure and miscellaneous types were low in fatality but high in frequency. Risk assessment based on these evaluation criteria will help decision makers establish and implement effective and practical accident mitigation measures for each type of accident.
