  • 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.

  • As a preliminary study of enter or leaving traffic patterns of the Korea main port, port Management Information System (Port-MIS) data was used to check the volume of vessels entering and leaving the port of Busan, and three consecutive days from each seasons were selected for study. Selected 12-day General Information Center on Maritime Safety & Security (GICOMS) data was also used to analyze the traffic pattern in the main traffic lane of Busan port for dangerous goods carrier. Also, the distance between dangerous goods carriers and Oryukdo breakwater of east breakwater in the main traffic lane was analyzed. Collision probability was estimated using the cumulative probability distribution function of the normal distribution for the maritime traffic safety audit scheme based on the assumption that a ship's trajectory has a normal distribution for a section of the route. However, in case of entry or leaving thorough the Oryukdo breakwater and entry thorough the east breakwater, ship's sailing trajectories were revealed not to follow a normal distribution via regularity testing using a KS-test and SW-test. Especially in the north port, the tendency of the right side of the ship to pass was remarkable. It is desirable to develop a traffic model suitable for the characteristics of the port rather than to apply general traffic theories, and to apply this model to a maritime traffic safety diagnosis, so further research is needed.

  • The congestion situation of Korea's port is further inclining due to the number of arriving and departing vessels and increase in the size of the size. Indicators for assessing whether the Vessel Traffic Congestion is called the Marine Traffic Congestion and it is used as a diagnostic entries in the Maritime Traffic Safety Audit System. In the diagnostic system, 6L (longitudinal) X 3.2L (transverse) is used as ship's domain in cases of harbor. This study is to determine the safety distance of the VTS officer and the ship operators by targeting the Busan harbor, which has the most number of ships that arrive/depart in Korea and listen to the communication of the VTS and calculate the communication time of the VTS officer and the ship operators for 7 days. By utilizing the distance communication port, the safety distance between the controllers and the ship operators is derived. It can be used for basic information of VTS Officer and Ship's operator's Safety distance in Busan port's in&out harbor.

  • As invigoration plan of the marine tourism, Busan City has the plan to operate the cruise ship inside of the harbor, but the area has narrow water way with heavy traffic. As a result it is requested to evaluate the safety for the preparation of actual navigation. In this study, the Ship Handling Simulation (SHS) Assessment was conducted, which is regulated by the Maritime Traffic Safety Audit Scheme (MTSAS) in compliance with the Marine Safety Law and the Maritime Traffic Risk Assessment System based on the Electronic Chart Display and Information System (ECDIS). The proximity assessment, control assessment and subjective assessment were implemented, which is enacted by the Marine Safety Law by using the SHS. In the case of proximity assessment, the probability of trespass was not analyzed. As the control assessment, the swept path was measured at 11.7 m and 11.5 m for port entry and port departure respectively, which exceeded the width of the model vessel, 10.4 m over; it was considered as a marginal factor. As a result of the subjective evaluation of the navigator, there would be no difficulty on ship maneuvering by paying particular attention to the mooring vessel nearby the Busan Bridge and Yeongdo Bridge as well as the coming vessel from the invisible sea area when the vessel is entering and departing the port. The Marine Traffic Risk Assessment System analyzed as [Cautious] level until the vessel passed the Busan bridge and the curved area at 5 kts and it became to [Dangerous] level from where it left 75 m to the Busan Bridge. When the vessel passed the Busan Bridge and the curved area at 10 kts and entered the narrow area, it indicated the [Dangerous] level and became to [Very dangerous] level from where it left 410 m to the Busan bridge. In conclusion, the vessel should maintain at the speed of 5 kts to reduce the risk when it passes this area.

  • 중대한 해양사고를 예방하고 잠재적인 해양사고의 원인을 제거하기 위하여 해상교통안전진단 제도가 "해상교통안전법" 개정('09. 5. 27)을 통해 정식 제도화되었다. 법 시행 이후 수행된 연구 중 하나인 '해상안전진단제도의 기술기준 및 고도화 연구'에서는 관련 평가 중 하나인 해상 교통혼잡도 평가에 사용되는 환산교통량 및 표준선이 현재 선박의 대형화 및 고속화 추세를 반영하고 있지 못함을 제시, 개선의 필요성을 말하였다. 이에 먼저 관련한 일본의 이론과 국내 진단대행업자의 평가 이론 현황을 파악 분석한 바, 이론 및 진단대행업자 별로 분석요소들을 다르게 사용하고 있어 표준화의 필요성을 발견하였고 또한 2010년 선박 입출항 통계를 이용한 선박현황을 분석한바 이론에서 사용하는 표준선과는 상당이 차이가 있음이 나타났다. 이후 관련 개선을 위한 기술기준(안)을 제안하여 전문가들의 의견 수렴과 이를 분석한 결과, 비록 소수의 상반된 의견이 있었지만, 표준선 변경에 따른 환산교통량 변화가 해상교통혼잡도에 미치는 영향은 그리 크지 않음을 알 수 있었다. 마지막으로 평가관련 개선을 위한 최종 기술기준(안) 및 앞으로 발전방향을 제시하여 해상교통 혼잡도 평가 발전을 위한 연구기반을 마련하고자 하였다.

  • Recently, around the world, active development of new renewable energy sources including solar power, waves, and fuel cells, etc. has taken place. Particularly, floating offshore wind farms have been developed for saving costs through large scale production, using high-quality wind power and minimizing noise damage in the ocean area. The development of floating wind farms requires an evaluation of the Maritime Safety Audit Scheme under the Maritime Safety Act in Korea. Floating wind farms shall be assessed by applying the line and area concept for systematic development, management and utilization of specified sea water. The development of appropriate evaluation methods and standards is also required. In this study, proper standards for marine traffic surveys and assessments were established and a systemic treatment was studied for assessing marine spatial area. First, a marine traffic data collector using AIS or radar was designed to conduct marine traffic surveys. In addition, assessment methods were proposed such as historical tracks, traffic density and marine traffic pattern analysis applying the line and area concept. Marine traffic density can be evaluated by spatial and temporal means, with an adjusted grid-cell scale. Marine traffic pattern analysis was proposed for assessing ship movement patterns for transit or work in sea areas. Finally, conceptual design of a Marine Traffic and Safety Assessment Solution (MaTSAS) was competed that can be analyzed automatically to collect and assess the marine traffic data. It could be possible to minimize inaccurate estimation due to human errors such as data omission or misprints through automated and systematic collection, analysis and retrieval of marine traffic data. This study could provides reliable assessment results, reflecting the line and area concept, according to sea area usage.

  • This research concluded that the area is most sensitively affected by the maritime traffic congestion rather than other factors including the ship's speed and fairway width. We performed a literature review for the area used in Japan, Denmark, and Shanghai ports, and analyzed by comparing with the area in Jinhae, Korea through the observation survey of marine traffic. The result of sensitivity analysis concluded that the congestion is affected by amount of 10% by changing 1 knot of the ship's speed, 18% of 100m of the fairway width, and 34%~43% of 1L of ship's length. By applying the result into the current audit system using $8L{\times}3.2L$, $6L{\times}1.6L$, we found that there is big difference with $3.5L{\times}1.5L$ in Japan, $5.9L{\times}2.2L$ in Shanghai, $4L{\times}5B$ in Denmark, and $3L{\times}2L$ in Jinhae, Korea. For this reason, further studies should be carried out in near future to the area mostly affected by congestion.
