It has been estimated that up to $80\%$ of all marine accidents have human elements as a cause. t of these, human elements of crew fatigue is main causes of marine accident. Crew fatigue involves sleep, schedule. workload. off-time. alcohol health and stress. With a ship handling simulator, the effect of alcohol on ship operational performance is studied for each 0.05 and $0.08g\%$ blood alcohol concentrations. A main effect for alcohol was found indicating that ship operational performance was significantly impaired by this alcohol relative to performance in the non-alcohol condition. The results of this research can be applied to minimize marine accidents as basic data.

The accident of Slip damage which arose between propeller boss and shaft will be a great problem of safety and economical due to the loss of propulsion power. In this study, the cause of slip damage on the large vessel was surveyed by meeting with officers of troubled ship, checking of drawings on the new built and surveyor report of adjuster company. Additionally, the material of propeller had been compression tested for confirming the impact strength. The result of this studies would be promote the design strength for contact force for keyless propeller, and futhermore reduce the accident of propeller slip between propeller boss and shaft.

In this study, we collected cases of accidents caused by swell in the east coast of Korea from 2013 to 2017. The location of the accident, the season, the type of coast and the type of damage were classified and the correlation between the accident and the wave data was analyzed by collecting the observation data of the nearby area at the time of the accident. Also, based on the results of the coastal disaster vulnerability assessment of Korea Hydrographic and Oceanographic Agency, the vulnerability grades of swell accidents area were evaluated. In swell accident area, the average grade of the wave exposure index was 4.91, the wave sensitivity index was 3.87, and the wave impact index was 4.90. As a result, most of the swell accidents occurred in the 5 grade (very vulnerable level) of the wave impact index, and the area of the east coast (78.7%) of the same 5 grade was classified into five types according to the wave sensitivity index result. Finally, a countermeasures was taken for characteristics of each type.

A total of 97,623 ships were registered in Korea in 2019. Among these, 65,835 vessels, accounting for approximately 67 % of the total number of ships, were registered as fishing vessels. As with the proportion of fishing vessels, the frequency of marine accidents is also high. In 2020, 2,331 of 3,535 accidents occurred on fishing vessels. Hence, various institutional arrangements are required for improving the safety of domestic fishing vessels. In this study, we examined domestic and international regulations on domestic and foreign control performance related to fishing boats for improving the safety of fishing boats. Additionally, the ratio of the rudder area of 153 fishing boats operating in Korea was investigated to examine the current status of the rudder area design of fishing boats whose design standards have not been clearly established compared to fishing boats. Resultantly, we statistically confirmed that most fishing boats were designing rudder areas because they did not meet international standards. In the future, these analysis results can be used as basic data to prepare rudder area design standards for improving the maneuvering performance of domestic fishing boats.

Despite the facts that navigation technology and educational programs were developed, and that maritime law has been enforced strictly, the number of maritime accidents has not dropped significantly. Accident prevention is emphasized because of the extreme life, property, and environmental losses that accompany maritime accidents. Even though there are a variety of preventive activities, their performance is not satisfactory. In order to promote preventive activities and to organize safety management, a Preventive Index of Ship Accident(PISA) and a Preventive Level of Ship Accident(PLSA) which are abstracted from the statistical data of ship accidents (2009~2013) are proposed. The survey module by which these variables can be calculated is composed of preventive domains such as education, engineering, enforcement and information, and is applied for the preventive indexes measurement of cargo, passenger, tanker, tugboat and fishery ships. We compared and analyzed measured result with statistical accident rates and cases to confirm the index utilities. It was found that there is some correlation between the index value and the ship accident rate. It is expected that this index will become useful to evaluate a preventive status for the prevention of ship accidents and for the maritime safety culture.

This study tries to give improvement directions of the law of oil spill focusing on the view that satisfying remuneration for victims should be considered. And it looks through the existing remuneration system provided by P&I Club and IOPC Fund. It also covers with issues related to remuneration in order to find the best for victims. The major contents of this study are as follows. First, the present law of compensation security to Marine oil pollution accident should be revised. Maximum value of remuneration needs to be raised and subjects liable to pay reparation need to be expanded. Second, in case the damage is widely different comparing to similar cases in foreign countries, it's hard to get complete remuneration from international corporations responsible for reparation. That's the reason the national emergency system for oil pollution must be established. Third, this study says the law that certainly defines a liability subject and that the liability is not necessarily caused by fault should be enacted. Last, it suggest that victims should have their object income data to facilitate establishment of the law of compensation for damages from marine oil pollution. To calculate proper remuneration, government should consider to choose one of public organizations as an investigator to damages and should collect accurate statistics relating to fishery. Furthermore, compensation system which can provide rapid reparation to victims needs to established by founding professional maritime organization of arbitration.

This study examined environmental condition, marine accidental data, marine traffic capacity and traffic flow, and fisheries zone status near Ulsan approaching water area. A questionnaire survey of marine traffic system was conducted on experts and users, and new plan was proposed. On the basis of the responses of experts and users to questionnaire, the essential factor of navigation danger and the essential factor of collision risk as well as the improvement plans were proposed. More efficient navigational fairway was set up through this study.

해상 교통 환경은 해운 산업이 발전함에 따라 더욱 복잡해지고 다양화되었다. 이에 따라 해상 교통 관제를 시행하는 선박교통관제사 업무의 중요성이 높아졌으며, 효율적인 교통 관제 시스템 지원을 위한 새롭고 다양한 시도들이 이루어지고 있다. 그러나 현재 선박교통관제에 관한 법률에서는 선박교통관제사의 업무에 대해 해양수산부령으로서 항만운영정보시스템에의 자료 입력을 규정하고 있으며, 이는 교통환경 파악 및 교통 관제에 집중하여야 하는 관제사에게 주의력 상실 등 비효율적인 관제 업무를 초래할 수 있다. 따라서 본 연구는 가장 입출항 선박이 많고 해양사고가 많이 발생하였던 부산항 VTS 센터의 관제사를 대상으로 시선측정실험을 실시하여 실제 관제 업무 시 관제 일지가 차지하는 비율을 확인하고자 하였다.

선박의 대형화, 고속화 및 선종의 다양화는 운송수단 중 해양 운송수단의 비중을 크게 증가시켰으나, 동시에 선박사고의 발생도 같이 증가되었다. 여객선의 경우 인명의 피해가 크게 발생하기 때문에 선박사고를 예방하기 위한 방법들이 논의되어 지고 있다. 본 연구에서는 여객선의 횡경사 각도를 바탕으로 전복의 위험까지 가게 되는 시간을 예측하여 위험시간에 도달하기 전에 인명을 대피할 수 있는 기초 자료를 제공하고자 하였다. 특정 시나리오를 설정하여, MOSES를 이용한 시뮬레이션을 수행하였으며 선형방정식을 이용하여 시뮬레이션 결과와 비교하였다.

선박교통관제 기본계획에 따라, 우리나라는 '26년까지 전 연안해역에 관제구역을 설치하여 안전관리를 강화할 예정이다. 본 연구의 목적은 관제구역 사각지대를 없애고 연속적인 관제 실현을 위한 관제구역 간 정보공유 활성화의 필요성을 제안하는 것이다. 이를 위해 우리나라 연안해역을 대상으로 해상교통 및 해양사고조사를 통해 우리나라 연안해역의 해상교통환경을 분석하였다. 그리고 해상교통관제사를 대상으로 설문조사를 실시하여 VTS 센터 간 정보공유 현황을 조사하고 문제점을 도출하였다. IALA에서 권고하고 있는 IVEF 서비스의 현황을 조사하고 정보공유 활성화를 위한 방안을 제시하였다. 본 연구의 결과를 통해 관제구역 간 정보공유의 필요성을 확인하고 나아가 IALA 표준을 개정할 수 있는 기초자료로 활용할 수 있을 것으로 기대한다.
