여객선의 안전성 향상을 위한 안전관리평가지표 개발에 관한 연구

Abstract

The main factors of causing marine accidents are the seafarer, vessel, and traffic environments. Except for the accidents caused by natural disasters, most of the marine accidents occur when there is a deficiency in one or more of the above factors. The major passenger ship accidents in domestic such as MV Nam-Young accidents, the MV Seohae accident were caused by the defects of these factors. Although the safety management system in Korea has been improved since then, there has been a consistent need for the betterment of the system for the prevention of continuing accidents such as MV Sewol ferry disaster in 2014.

Especially, due to its nature, the influence of the passenger ship accident is critical, despite the fact that the number of passenger ship accident is only 2.0% of the whole marine accidents.

To prevent these accidents, passenger ships must secure seaworthiness before its operation. However, safety management system for evaluating seaworthiness for passenger ships had not yet been developed.

In this study, safety management system for passenger ships was proposed. To develop the system, subtleties of different criteria such as ship stability, seafarer's training, regulations for safety management, and management of passengers were taken into account.

Also, Safety Evaluation Index was estimated by carefully analyzing the passenger ship accidents since 1962' and was used to evaluate the system. Hull, seafarer's training, regulations for safety management, passenger/cargo management, and other factors were considered and specific criteria for each factor were defined for the evaluation.

Furthermore, Safety Evaluation Index was applied to the major catastrophes of passenger ships, such as Sinking of the MV Nam-Young 1970, MV Seohae in 1993, MV Sewol in 2014 and the reliability of the proposed methods was reviewed. Through the estimation of Safety Evaluation Index, it would be possible to assess the safety management level of the passenger ships, which will eventually be used for establishing the regulations in regards to preventing accidents of passenger ships.
