According to the change of maritime environments and the development of science and technologies unidentified risk factors are created day by day in the world. It is crucial reason for the occurrence of maritime accidents that the unidentified risk factors make unexpected and extra-ordinary cases. Thus prior identification of unidentified risk factors is key issues to prevent maritime accidents. In addition to the identification of risk factors, the identification and classification of ongoing risk factors and evaluation model in the future is also one of key issues to consider unidentified maritime accidents. In this study, we searched on the conventional risks and unidentified risks to find risk control options for new, unidentified and expected risks.

In order to prevent the dangers of major marine accidents, it is very important to be aware of in advance through marine incidents in the background of Heinrich's law, formulated by the safety pioneer who is credited with focusing on workplace safety with emphasis on the human element. At least 11 cases of collision accidents occurred in the Busan VTS area from January 1st to December 31st, 2019, and 24 cases of VTS marine incidents were reported during the same period. According to Heinrich's law, there could be many more potentially risky situations besides the 24 reported cases. In this study, the criteria for VTS marine incidents were established through advanced research and a survey of VTS operators, and analysis of 24 cases of VTS marine incidents in the Busan VTS area. Traffic surveys were conducted for three days to identify potentially hazardous situations. According to the survey, there were 216 cases of VTS marine incidents, and within a year, it is estimated there could be about 26,280 cases. Even if conditions such as "missing VHF communication feedback" which is an important cause of marine incidents, are not reflected, there are many potential risks in the VTS area. Thus, it is vital to strengthen the VTS marine incident reporting system.

For many years, fatigue of ship's crew was discounted as a potential cause of or contributor to human error. However, resent accident data and research point to fatigue as a cause of and/or contributor to human error precisely because of its impact on performance. The goal of this study is to analyze and examine of the fatigue factors related to human error. In this study, we carried out the questionnaire survey which concerned with the fatigue factors.

Since July 2006, marine traffic safety management system have been enforced to support the vessels transiting across the coastal area and the vessels coming in and out of ports in southwestern coastal area where heavy traffic density and marine casualties occurred frequently. The marine traffic volume for the marine traffic environmental assessment was measured by the information from RADAR and AIS system in the area. The distributions of marine casualties were analyzed in the main routes and traffic separation schemes during the last five years and the navigational dangerous elements were investigated with the influence of natural environment, the distribution of fisheries and survey questionnaire. Marine accidents of merchant ships have a tendency to decrease gradually but in case of fishing boats, the rate of marine accidents have a contrary results in this area during the last five years. The dangerous elements on navigation appeared to be the dense force from June to August, fisheries activities and the vessels which not follow the compulsory watch on VHF-band radio communication equipments.

As the numbers cf vessels in and out cf korean ports and passing ships through korean waters are increasing, possibilities of marine accidents grow higher and damages caused by such accidents would be expected larger. The author accordingly try to seek for the appropriate measures to enhance the present korean Search and Rescue(SAR) systems and future plans comparing korean system with international movement and relevant systems of maritime advanced countries.

Recently, about 600 cases of marine accidents occur annually in Korea. According to many studies and analyses on occurrence of marine accidents, 70~80% of marine accidents were caused by human factors. Among the human factors, navigation officers' fatigue is very important factor. Although navigation officers' fatigue serves as an important role in marine accidents, there is no method to exactly examine the degree of officers' fatigue. Accordingly, this study analyzed human factors according to types of marine accidents and extracted important five factors affecting navigation officers' fatigue through the questionnaire survey by means of literatures and 5-point scale. In addition, evaluation factors of marine accident risks caused by fatigue factors were divided and structured by using ISM. Lastly, it found out the importance of each fatigue factor drawn by AHP and decided marine accidents that were most highly caused by navigation officers' fatigue in order. At the result, weights were high as sleep time 0.385, stress 0.302, health condition 0.139, rest time 0.099, alcohol and drug 0.074 in fatigue factors, and death and injury 0.328, collision 0.308, grounding 0.195, sinking 0.094, fire accident 0.075 in evaluation factors of marine accident risks. Therefore, the control plan to lower marine accident risks should be prepared on the basis of high weight factors.

In December 1998, Act on the investigation and inquiry into marine accidents was amended by inserting new Paragraph (2) of Article 4, which states "Where two or more persons are related to the occurrence of a marine accident when the Maritime Safety Tribunal(hereinafter referred to as the "MST") examines the causes of a marine accident as provides for under Paragraph (1), the MST may disclose the extent to which each responsible person is related to the cause of the marine accident". Based on this new Paragraph, the apportionment system of causation ratio in the ship collision was introduced in February 1999. However the apportionment system is adopted 12 years ago, public debate has continued about the positive and negative aspects of the system. Thus some groups advocate the system for the advantages, but other groups argue that this system should be abolished. Therefore, at first, this study analyzes the adopting background and the main reasons of the pros and cons discussion on the apportionment system of causation ratio in the ship collision. Then we conduct a survey analysis to investigate stakeholder's satisfaction of this new system in the ship collision cases. Finally this study suggests the policy proposal to improve the apportionment system of causation ratio in the ship collision.

유리강화섬유(FRP,Fiber Reinforced Plastic)은 가볍고 내구성등이 우수하여 가공하기 쉬워 선박건조, 특히 어선의 건조재료로 많이 활용되고 있으나, FRP의 재료인 매트와 로빙이 인화성을 가진 수지와 접합되어 화재에는 매우 취약한 특성을 가지는 특성을 가진다. 최근 10년간의 중앙해양안전심판원의 어선화재 재결서 분석결과 전체의 약80%에 해당하는 화재사고가 기관실에서 발생하였다. 이에 새로 출범한 해양수산부는 FRP선박의 구조기준을 개정하여 총톤수10톤 이상 선박의 기관실에 대한 방화조치를 그 이하선박까지로 적용 확대하였으며, 어선구조기준 역시 행정규칙 행정예고를 통해 강화하려는 움직임을 보이고 있다. 본 지에서는 국내외 화재사고 발생현황 및 관련 규제 내용을 비교 분석하여 제시하였으며 분석결과, 일반선박의 방화조치에 대한 규제는 거의 유사하였으나 어선관련 규제의 경우, 영국의 규제가 가장 강화되어 있었으며 관련 화재사고 발생현황도 국내 및 일본과 비교해 보았을때 같은 기간 발생한 일반선의 화재발생척수 대비 어선의 화재발생척수가 적은것을 확인할 수 있었다.

미국 해안경비대 및 영국 해양사고조사국에 의하면 해양사고에서 인적과실의 원인중 상당부분 선원 피로에 기인하는 것으로 조사되었으며, 스웨덴에서의 연구 결과 약 73% 정도 선박 당직근무자들이 당직 근무 시간 중 최소 1회 또는 그 이상 졸음에 빠져 있는 것으로 보고하고 있다. 본 연구에서는 국내 연안선 항해당직자들을 대상으로 Workload를 분석하였으며, 효율적으로 Workload를 측정할 수 있는 방안을 제시하였다.
