Abstract

Many studies have analyzed marine accidents, and since marine accident information is updated every year, it is necessary to periodically analyze and identify the causes. The purpose of this study was to prevent accidents by identifying and analyzing the causes of marine accidents using previous and new data. In marine accident data, 1,921 decisions by the Korea Maritime Safety Tribunal on marine accidents on fishing ships over 16 years were collected in consideration of the specificity of fishing ships, and 1,917 cases of accident notification text history by the Ministry of Maritime Affairs and Fisheries over 3 years were collected. The decision data and text data were classified according to variables and quantified. Prior probability was calculated using a Bayesian network using the quantified data, and fishing ship marine accidents were predicted using backward propagation. Among the two collected datasets, the decision data did not provide the types of fishing ships and fishing areas, and because not all fishing ship accidents were included in the decision data, the text data were selected. The probability of a fishing ship marine accident in which engine damage would occur in the West Sea was 0.0000031%, as calculated by backward propagation. The expected effect of this study is that it is possible to analyze marine accidents suitable for the characteristics of actual fishing ships using new accident notification text data to analyze fishing ship marine accidents. In the future, we plan to conduct research on the causal relationship between variables that affect fishing ship marine accidents.

해양사고 분석에 관한 많은 연구가 진행되고 있으며, 해양사고는 매년 업데이트되고 있어 주기적으로 원인을 분석하고 규명하는 것이 필요하다. 이 연구에서는 이전의 데이터와 새로운 데이터를 활용하여 해양사고를 파악·분석을 통해 어선 해양사고 원인을 규명하여 사고를 예방하는 것이다. 해양사고 데이터는 어선의 특수성을 고려하여 해양안전심판원의 어선에 대한 해양사고재결서 16년간의 1,921건을 수집하였으며, 해양수산부 종합상황실 사고알림문자 이력 3년간의 1,917건을 수집하였다. 재결서 데이터와 문자 데이터는 변수에 따라 분류하였으며, 수량화 작업을 수행하였다. 수량화 작업을 통한 데이터를 사용하여 베이지안 네트워크를 이용해 사전확률을 계산하였고, 후방 추론을 이용하여 어선 해양사고를 예측하였다. 두 가지 수집한 데이터 중 해양사고재결서는 모든 어선의 사고가 재결서에 포함되지 않았기 때문에 해양수산부 사고알림문자를 선택하였다. 분류한 데이터를 베이지안 네트워크를 사용하여 어선 해양사고의 사전 확률을 계산하였다. 후방 추론으로 계산한 기관손상이 서해 연안에서 발생할 어선 해양사고의 확률은 0.0000031%였다. 이 연구의 기대효과는 어선 해양사고를 분석하기 위하여 새로운 사고알림문자 데이터를 활용하여 실제 어선 특성에 맞는 해양사고를 분석할 수 있다는 것이다. 추후에는 어선 해양사고에 영향을 미치는 변수들 간의 인과관계에 관한 연구를 수행할 예정이다.
