According to the statistics of KMST (2010~2019), 68.5% of marine casualties have been occurred in fishing boats in the last 10 years. Although the incidence rate of annual average per ship is 10.4% for merchant ships and 2.3% for fishing boats, it is necessary to first reduce the marine casualties of fishing boats in order to reduce the occurrence of the whole marine casualty, considering that the number of registered fishing boats are 86.5% of the total. In this study, the top 10 fishing types with high occurring marine casualties in the past 10 years were selected using the statistics of KMST. Then, the causes of the marine casualties, focusing on the collision, were analyzed and counterplan were suggested. The biggest marine casualty that the top 10 fishing types have caused in the past 10 years was a collision, accounting for 71.7% of the total, and the rest were less than 10.0% each. Also, it was found that the biggest environment and cause of the collision were due to human factors such as poor look out or negligence of duty. Eventually, it was concluded that a reduction in the human factors for the causes basically, could lower the incidence of the marine casualties. Therefore, if the continuous and systematic correcting education of the attitude toward the ship operating of seafarers could conducted with the focus on the main human factors, the whole marine casualties will be expected to decrease gradually.

2016년 3월 6.67톤 어선이 크레인 작업을 하던 중 복원성 상실로 인한 전복 사고가 발생하였다. 전복은 충돌, 접촉, 좌초, 화재 및 폭발의 결과로 발생한 사고는 제외하고 선박이 뒤집힌 것을 말한다. 지난 9년동안(2010-2018), 전복 사고는 전체 해양사고의 2.34%를 차 지하고 있으며 증가와 감소를 반복하고 있다. 10톤 미만 소형어선의 주된 전복사고 원인은 부적절한 선적에 따른 복원성 상실이다. 어선 법에 따르면 소형 어선은 복원성과 1톤 미만 제한 하중 크레인에 대해서 복원성과 예비검사를 면제해 주고 있다. 본 연구는 고성에서 발 생한 소형 어선의 전복 사고 재결서의 원인으로 언급된 사항 중 크레인 증량에 따른 복원 모멘트 감소에 대해 실제 제원이 비슷한 어선 을 모델링하여 이를 통해 사고 전·후의 어선 상태를 가상하여 복원성을 비교하였다. 그 결과 기존 보다 무거운 크레인으로의 교체 시에는 복원 모멘트 감소와 현단몰입각의 감소로 전복의 위험성이 증가되었다. 표준재화 상태에서는 입·출항시 보다는 어로 활동을 하고 있는 상황에서의 복원 모멘트가 감소되는 것을 확인하였다.

This research carried out a study on the job characteristics of the skipper of the coastal composite fishing vessels in order to find a way to prevent the ship collision caused by the highest human error among the marine casualty of fishing boats. Video observation was used as the research method in which six CCD cameras were installed on the vessel to collect image data and data extracted from the image were analyzed to derive the results of the functional activity of skipper according to the fishing operation process of experimental fishing vessel. The results are as follows. The working process of the experimental fishing vessel consisted of navigation for fishing ground, setting line, waiting for hauling line, hauling line and navigation to homeport. In these processes, the skipper was performing watchkeeping in the wheelhouse in which he carried out a single task, a dual task that performed two tasks simultaneously, and a triple task that performed two or more tasks simultaneously. In addition, one of the risk factors causing the collision was a no watchkeeping in the wheelhouse for navigating for fishing ground, waiting for hauling line, and hauling line at 25.4%, 64.6% and 0.3%, respectively among the marine casualty while drowsiness caused 1.2% of the marine casualty in navigating for fishing ground. Concurrent tasks that simultaneously perform two or more tasks that can overlook any other important duties while carrying out watchkeeping in the wheelhouse include 51.3% of navigation for fishing ground, 81.9% of setting line, 19.0% of waiting for hauling line, 87.9% of hauling, and 88.7% of navigation to homeport. The above concurrent tasks yielded an average of 66.1%. Experimental fishing vessels are required to focus on ship handling operations related to fishery operations, and the skipper is assigned more activities and attention to fishery related tasks. Therefore, it is considered desirable to build a collision prevention system that is appropriate to the characteristics of the skipper’s work, escaping from transferring the responsibility of ship collision to the skipper completely.

우리나라 해역에서 발생하는 해양사고 중 어선사고가 약 70%를 차지하고 있음에도 불구하고, 대부분의 연구는 해양사고 전체를 대상으로 하고 있으며 단순히 사고 발생률에 대한 분석과 사고 발생 빈도를 줄이기 위한 대책 마련에 중점을 두고 있다. 그러나 효과적인 사고 저감 대책의 수립과 이를 실행하기 위해서는 정량적인 사고 위험도 예측 및 평가가 반드시 선행되어야 한다. 본 연구에서는 해양안전심판원의 최근 5년간의 어선사고 통계에 근거하여 9가지 사고유형에 대한 위험도를 연도별로 비교하였다. 또한 현재 우리나라의 경우 객관적인 위험도 평가기준이 없다는 점을 고려하여 이에 대한 대안으로 사고 유형별 사고 빈도와 사고 피해의 조합을 4사분면 상에 표시하는 2차원 사고 빈도-피해 매트릭스를 제안하고 이를 이용하여 사고 빈도와 사고 피해의 영향을 쉽게 확인할 수 있도록 하였다. 이러한 과정을 통한 위험도 평가 결과는 저감대책을 수립하고 안전대책을 마련하는 정책 제안자로 하여금 보다 다양하고 현실적인 사고 저감 대책을 마련하는데 도움을 줄 것이다. 또한 위험도 평가 매트릭스를 이용하여 각 사고유형에 대한 인적오류를 포함한 사고 원인의 상대적인 빈도 및 결과를 비교함으로써 사고 유형별로 원인에 따른 차별화된 위험 저감 대책을 수립할 수 있다.

Marine casualties of small fishing vessels (SFV) of less than 20 tons are frequent in Korea. The analysis was conducted to identify the cause and then prepared reduction plan using the marine casualty statistics of fishing vessels for the last five years from 2012 to 2016 by the Korean Maritime Safety Tribunal to reduce the marine casualties of SFV. According to the analysis of the type of whole vessels occurring marine casualty, fishing vessels accounted for an average 68.0 %; moreover, except for 2014 when M/V SEWOL ferry capsizing occurred, the rate of death and missing due to marine casualties occurred from 68.3 % to 91.2 % in fishing vessels, and an average 79.5 % was found to be urgent need of a measure. Marine casualties occurrence depending on the gross tonnage of fishing vessel was found that the most occurred at less than 5 tons, followed by the order of 5 to 10 tons or less. However, crews who boarded on SFV do not have any training program for them, except for the fishing safety training of fisher who carry out fishing for shipowners and crew of the coastal and offshore fishing vessel in accordance with the safety regulations for fishing vessels in the Fisheries Cooperative Association. Therefore, it is necessary to revise the training program so as to improve the preventive action and then emergency response including the fishing safety compliance with each fishery, safe navigation, machinery inspection and emergency response. Also, an SFV of less than 5 tons of 56,000 vessels is boarded by unqualified fishers. It would also be possible to consider subdividing small boat operator’s certificate to enhance their qualifications. It is expected that marine casualties of SFV will be reduced if active efforts are made to improve the safety consciousness of fisher and shipowners as well as the reorganization of fishing safety training and the small boat operator’s certificate system.

The most frequent occurring and the serious marine casualties in fishing vessels are the collision in statistics from Korea Maritime Safety Tribunal (2008-2015). Collisions are is given a great deal of weight in all marine casualties, and the main cause of collisions is the negligence of watching. From this point of view, this study deals with the collision and its immediate cause, the negligence of watching which are main factors on the indirect causes. Basic analyzing data was gathered from the questionnaire made by experts of sea service part, and analyzed by using the fault tree analysis (FTA). From the result of the study, the occurrent probability of the negligence of watching in the collision due to the indirect causes occupied 64.9%, and its probability caused by the man factors was less than the other factors; i.e. the media factors and the management factors. For the reduction of the negligence of watching in the collision from this study, it needs an effort to remove not only the man factors, but also the media factors and management factors.

Marine casualties originated from fishing vessels occupied about 71.2% of the whole marine casualties in Korea from 2008 to 2014, which has not changed much for a long time. Therefore, a pragmatic counterplan to decrease in casualties in fishing vessel is indispensable for reduction of marine casualties in Korea. Since the casualties occurred by fishing vessels may incline to a specific type of casualties according to the difference in the operating type; in this paper, 11 fishing types which occurred casualties frequently in numbers and occupied ratio were selected. Since the most frequent occurring casualties in fishing vessels were from collisions and fire explosion in statistics from KMST (2008~2014), the study focused on them. The collision is given a great deal of weight in all the casualties mostly due to the negligence of duty regardless of the job types. Gill netter, trap fishing boat, jig boat, multiple fishing boat and stow netter have their own specific causes of casualties in collision according to the operating types. The cause of fire explosion was mainly due to poor inspection and maintenance the electric cord. For this reason, it may be necessary for an operator to make strict precaution on the other vessels under way systematically, keep the regulation for preventing collisions, and for an engineer on watch to make a check the electricity periodically to reduce the fire explosion.

외국인 선원은 1990년대 선원 수급이 어려웠던 어선에 산업연수생으로 승선하기 시작하여 2013년말 현재 상선 및 어선에 총 21,327명이 승선하고 있다. 특히 원양어선 및 연근해어선의 경우에는 최근 5년간 어선 척수가 감소하고 있음에도 불구하고 외국인 선원의 수는 거의 2배 증가하였다. 최근 어선 해양사고를 살펴보면, 어선에 다국적의 선원이 승선한 후 선원 상호간의 의사소통이 어려워진 것이 주요 문제가 되었다. 그리고 외국인 선원이 이해할 수 있는 안전수칙 등이 제공되지 아니하고 교육․훈련이 제대로 이루어지지 않고 있다. 그 결과 어선은 조업 중 해양사고의 발생 위험이 높아졌고, 비상상황에서 선장의 통제 하에 적절한 비상대응이 이루어지지 않았다. 또한 한국인 선원의 외국인 선원에 대한 폭언 및 구타로 인한 몇 건의 노동문제가 발생했다. 따라서 본 논문은 먼저 외국인 선원이 승선한 어선에서 발생한 해양사고 사례와 어선원의 고용 및 교육문제에 대해 살펴보고, 해양사고 예방을 위하여 외국인 선원에 대한 안전수칙교육과 정기적인 비상대비 교육․훈련의 필요성을 제시하고자 한다.
