Abstract

According to the statistics of maritime accidents statistics that have occurred in Korea over the past five years, maritime accidents caused by fishing boats have increased every year from 1,646 in 2016 to 2,100 in 2020. In particular, of the 378 capsizing accidents that have occurred in the past five years, 252 capsizing accidents of fishing boats account for a high proportion of 66.7%, therefore, it is urgent to come up with countermeasures. In this study, to determine the cause of the capsizing accident of fishing boat No. 66 poongsung, data such as stability and seawater inflow routes were collected, and the effects of waterproof, additional wood decks, and windbreakers on stability on were quantitatively analyzed. Additional decks, windbreakers, and waterproof installed in No. 66 poongsung cause initial list, deteriorate stability, and fail to meet fishing boat structural standards. In addition, it was analyzed that the stability was weakened due to the characteristics of the hull shape of No. 66 poongsung. To estimate the stability at the time of the accident, the stability at the time of the working in the fishing ground condition, amount of seawater inflow according to the change in sea conditions, hull oscillation situation, and change in stability due to the hull factor were calculated. As a result, the minimum GoM was satisfied at the time of working in the fishing ground, but it could not be restored at the maximum wave height of 4 m, and the minimum GoM was not satisfied at the maximum wave height of 4 m owing to the influence of seawater inflow and oscillation due to the hull list. However, the minimum GoM was satisfied if additional decks and windbreakers installation was excluded among the factors affecting the stability of No. 66 poongsung.

최근 5년간 국내에서 발생한 해양사고를 선박용도별로 살펴보면 어선이 67.1%(10,211척)를 차지하고 있으며, 어선에 의한 해양사고는 2016년 1,646건에서 2020년 2,100건으로 매년 증가하고 있다. 특히 최근 5년간 발생한 378건의 전복사고 중 어선의 전복사고가 252건으로 66.7%의 높은 비중을 차지하고 있어 이에 따른 대책 마련이 시급한 실정이다. 본 연구에서는 어선 제66풍성호의 전복사고의 원인 규명을 위해 복원성 및 해수 유입경로 등의 자료 수집과 풍성호에 설치된 방수구, 추가 갑판 및 바람막이 등이 복원성에 미치는 영향을 정량적으로 분석 후 전복사고의 대응 방안을 제시하였다. 복원성에 영향을 주는 요인으로 풍성호에 설치된 추가 갑판, 바람막이, 방수구가 초기 횡경사를 일으키고, 복원성을 악화시키며 어선구조기준을 충족시키지 못할 뿐만 아니라 풍성호의 선형 특성 등으로 인해 복원성을 약화 시키는 것으로 분석되었다. 사고 당시의 복원성을 추정하기 위해 어로작업 시점의 복원성과 해상 상태 변화에 따른 해수 유입량 및 이에 따른 동요 상황, 그리고 선체 요인에 의한 복원성 변화를 계산하였다. 그 결과, 어로작업의 시점에서는 최소 GoM을 모두 만족하였으나 최대파고 4m에서 복원이 불가하였으며, 선체 경사에 따른 해수 유입, 동요의 영향에 의해 최대파고 4m 상태에서 최소 GoM을 만족하지 못하는 것으로 분석되었다. 그러나, 풍성호의 복원성에 영향을 미치는 요인 중 추가 갑판과 바람막이 설치를 제외한다면 최소 GoM을 만족하는 것으로 분석되었다.
