The Maritime Safety Act established restrictions for the passage of oil tankers, prohibiting vessesl carrying more than 1,500 kiloliters of oil or 1,500 tons of a hazardous liquid substance. Prohibited vessels that do not satisfy the restrictions are allowed to enter and depart from a nearby port from the outer sea area to minimize the time and distance the oil tanker must navigate in the prohibited area. Therefore, such regulation should not be construed as referring to inshore traffic. In this study, the traffic volume of coastal tankers that do not use the approaching channels for specific sea areas near Yeosu and Gwangyang Port was analyzed, and the cargo loads of these ships were investigated. The results of this study should be used to allow tankers to minimize the time and distance of navigation in prohibited areas. According to the survey, 16 vessels, 51.6 % of the 31 vessels using inshore traffic included in the study, were loaded with more than 1,500 tons of cargo. This is not appropriate according to the legislation for oil tanker passage. Therefore, in this study, sea routes have been proposed that connect with the approaching channels of specific sea areas, from the outer sea areas of restricted passages. Regulations have also been proposed for the entry and departure of oil tankers around Yeosu and Gwangyang Port.

The Maritime High School's Two plus One Onboard Training system is introduced to increase amount of graduate students to board on a ship for improvement of Ministry of Land, Transport and Maritime Affairs' policy. Students with this system study in school for two years and complete practices in ship for one year so that graduate students from this system can get officer license with only interview exam. This program Iud been developed to attract more graduate students to board on ships longer according to the fact that students now are avoiding life on ships. Four years after the system had been introduced, this research aims to find out problems of the system by questionnaire regarding practices on ships to current students from which to introduce methods of leading longer lie on ships of students.

Maritime traffic safety audits (MTSA) were enacted in order to ensure marine traffic safety throughout changes or the construction of water facilities, port facilities, etc. After the introduction of MTSA, the scope of subject vessels was restricted to an LOA of more than 100 m or a maximum speed of more than 60 knots as of 2014. In this study, the scope of subject vessels was re-examined in comparison with specific marine traffic safety areas and tanker prohibited areas identified in the maritime safety act. Furthermore, the state of subject vessels and exception cases for MTSA were also analyzed. As a result of these analyses, MTSA were deemed necessary for dangerous goods carriers of more than 1,000 G/T in specific marine traffic safety areas and dangerous goods carriers of more than 794 G/T in tanker prohibited areas. Finally, the necessity of further review was suggested given the present scope of subject vessels.

This study estimates the demands for safety training courses with reference to research on safety training records, seafarer statistics, target groups for safety training, expiry dates of existing safety courses, seafarer employment rates, the retirement age, etc. These results are compared with the seating capacity of the maritime training institute to analyze the anticipated increase in and convergence of demand can be accommodated. The average annual safety training needs for the next five years according to the Seafarers Act include approximately 10,444 people, and the proper annual seating capacity of the maritime training institute is approximately 7,280 people at present. Thus, in order to respond to an increasing demand for safety training, it is necessary to expand the capacity of the safety training facility.

The efforts for improving 'Maritime Traffic Safety Assessment Scheme(MTSA scheme)' have continued to the present since May 27th, 2009. But recently, there's a controversy about whether it has been performed properly or the results is significant. These new discussions were arose from lack of validity and appropriateness we had yet to find. At this point, it needs to establish sound MTSA scheme through the comprehensive review. This research developed a suitable meta-evaluation model for MSTA with applying theory of the teta-evaluation, that is the evaluation of evaluations and verified by using meta-evaluation methods like as literature studies, expert reviews, surveys and etc. The results of this study can be used to evaluate MTSA activities and it will contribute to improving MTSA scheme.

Intelligent maritime traffic information service for maritime traffic safety operates a service that provides safe and efficient optimal safety routes considering information such as water depth, maritime safety law, weather information, and fuel consumption. However, from a service user's point of view, they prefer a route that suits their personal navigation experience and style, such as unnecessary detours and conservative safety distances for maritime objects. In this study, the optimal safety route can be extracted based on the experience of service users without reflecting the separate maritime environment by adjusting the weight of the trunk line for the area where the ship frequently navigates with the ship's track data collected through LTE-M model was studied.

Waters that are under surveillance for traffic safety designated area due to increased risk of ship accidents are usually areas in the coastal waters specified by the government. However, there are still some controversies surrounding application of navigation rule in regards to these waters. Such law is especially difficult to apply to VTSO access sea route within Kwangyang bay area. Therefore, as a solution for the issues discussed in this research, the goal is to help establish a unified application method for navigation rule in relation to VTS areas, to improve marine traffic safety by separating and applying specific laws from marine safety law, and to provide a ground on which the VTSO can take a proactive and focused approach in performing monitoring duties.

This study identified necessary navigational support services to prevent accidents through an examination and a survey on the navigation and communication systems of non-SOLAS ships. The functional and operational requirements for the identified navigational support services were discussed accordingly. Among the navigational support services proposed are an Electronic Navigational Chart (ENC) service, a route planning service, an operation monitoring service, and collision prevention support services for ships in coastal areas. To facilitate the identified navigational support services, ship navigation system, shore supporting centre and maritime communication network were discussed as a digital infrastructure. The operational methode for the digital infrastructure were discussed in the service scenarios for ships carrying dangerous cargo, large ships over 200 meters in length and high speed passenger ships over 15 knots in speed. This study will facilitate the development of policies for the improvement of ship operation management in Korean coastal waters and will contribute to improving the navigational safety of non-SOLAS ships.

Over the last ten years, the number of entanglement marine accidents has increased more than other accident types. This study analyzed the annual statistical report of marine accidents from the Korea Maritime Safety Tribunal and Korea Coast Guard. Despite some discrepancies between data of the two organizations, it was found that marine accidents involving fishing vessels were more prevalent than those involving non-fishing vessels. In addition, the main floating materials that caused wounded entanglement accidents were fishing nets, fishing gear, and ropes, and the proportion of them was high. Foreign and domestic policies on marine plastics recognize most marine plastics as marine environmental hazards and focus on marine litter recovery and the prevention of marine pollution. The representative Acts related to the marine environment and marine litter, the Marine Environment Management Act and the Marine Waste and Sediments Management Act, recognize marine litter as a type of marine waste, and deal with the types and definition of this waste. However, clearly defining marine waste is difficult. Therefore, this study tried to examine the relevant legal system of marine litter on ship operation and suggested improvement measures. Moreover, the definition of marine litter for the safe navigation and operation of ships was clearly proposed.

원전에서 발생하는 중 저준위방사성폐기물(이하, "방폐물"이라 함)을 처분시설로 운반하는 것은 원전과 처분시설이 임해지역에 위치하고 있으므로 육상운반보다는 선박을 이용하는 해상운반이 효율적이다. 해상운반은 무엇보다 다량운반이 가능하며 이로 인하여 운반회수가 줄고, 인구밀집지역을 지나지 않아도 되기 때문에 방폐물의 운반에 대한 위험도가 상대적으로 적어 안전성 확보에 유리하다. 방폐물의 해상운반은 운반 도중 방사성물질의 위험으로부터 인간과 환경을 보호하기 위하여 국제원자력기구(IAEA)의 안전운반규정, 국제해사기구(IMO)의 국제해상위험물규칙, 국내 원자력법 등 국내외의 엄격한 기술기준에 따라 안전성이 철저하게 보장되어야만 한다. 한국수력원자력(주)(이하, "한수원"이라 함)는 원전(월성원전 제외)에서 처분시설까지 방폐물을 안전하고 효율적으로 운반하기 위하여 전용운송선박, 운반용기, 전용운반차량 및 원전 물량장 등으로 이루어지는 해상운반시스템을 구축하여 운영할 것이다.
