우리나라 항만을 입출항하는 선박은 연간 390,245척(2013년)이며, 연안해역을 통항하는 선박은 우리나라 남해안이 세계에서도 통항척수가 많은 해역이다. 이러한 연안 해역에서 거리별 통항교통량 분포 및 해양사고 분포를 통하여 연안해역 거리별 위험도를 파악하여 교통량 분산 등을 유도하여 해상교통 안전을 향상시키는데 목적이 있다.

본 연구에서는 해상교통관제제도(VTS)가 적용된 연안해역에서 해상통항흐름에 영향을 미치는 요소를 알아보고자 하였다. 본 연구의 목적을 달성하기 위해 해상교통환경조사는 2007년도부터 2012년까지 어장, 어로활동 및 해양구조물에 대한 마로해 인근해역에 대해 현지 조사방법을 사용하였다. VTS에서 제공하는 서비스종류에 대해 국제표준과 국내 적용 규정을 비교하고 2011년 연안해역에서 제공된 서비스에 대해 분석하였다. 동 해역의 해상교통흐름은 레이더와 선박자동식별장치 정보를 시공간적으로 중첩시켜 최근 6개월간 흐름패턴을 조사하였다. 연구 대상해역은 서남해 진도 인근해역($3,800km^2$)으로 통항분리제도와 탱커선통항금지해역 및 다도해해상국립공원을 포함하고 있다. 연구결과 연안해역에서 제공되는 서비스를 통해 해양사고를 18% 감소시켰다. 서비스 제공수준은 비정규분포를 보이며 공정능력은 향상된 것으로 나타났다. 안전한 해상교통환경 유지하기 위해 정기적인 연안해역 모니터링 및 관리체계의 확립에 대한 대응이 요구된다.

The characteristics of ship traffic routes and the long term fluctuation in marine traf ic volume of the incoming and outgoing routes of the Yeosu Gwangyang Port were analyzed using vessel traffic data from the past 22 years and a real-time vessel traffic volume survey performed for 72 hours per year, for three years, between 2015 and 2017. As of 2017, the number of vessels passing through Yeosu Gwangyang Port was about 66,000 and the total tonnage of these ships was about 804,564 thousand tons, which is a 400 % increase from the 189,906 thousand tons shipped in 1996. Specifically, the dangerous cargo volume was 140,000 thousand tons, which is a 250 % increase compared to 1996. According to the real-time vessel traffic volume survey, the average daily number of vessels was 357, and traf ic route utilization rates were 28.1 % in the Nakpo sea area, 43.8 % in the specified sea area, and the coastal area traf ic route, Dolsan coastal area, and Kumhodo sea area showed the same rate of 6.8 %. Many routes meet in the Nakpo sea area and, parallel and cross passing were frequent. Many small work vessels entered the specific sea area from the neighboring coastal area traffic route and frequently intersected the path of larger vessels. The anchorage waiting rate for cargo ships was about 24 %, and the nightly passing rate for dangerous cargo ships such as chemical vessels and tankers was about 20 %. Although the vessel traffic volume of Yeosu Gwangyang Port increases every year, the vessel traffic routes remain the same. Therefore, the risk of accidents is constantly increasing. The route conditions must be improved by dredging and expanding the available routes to reduce the high risk of ship accidents due to overlapping routes, by removing reefs, and by reinforcing navigational aids. In addition, the entry and exit time for dangerous cargo ships at high-risk ports must be strictly regulated. Advancements in the VTS system can help to actively manage the traffic of small vessels using the coastal area traffic route.

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 prevention of marine accidents has been a major topic in marine society and various policies and countermeasures have been developed, applied to the industries. The coastal VTS and navigational aids are considered a, one of the effective methods to promote marine safety but they need relatively huge amount of budgets to build. Thus prior to establishing these coastal VTS and navigational aids, it should be evaluated the navigational risk level in the coastal waterways from the Environmental Stress. So far as human beings are concerned, there are many types of fuzziness in the evaluation of navigational safety level. In order to reflect these fuzziness on this evaluation, this paper introduces the fuzzy integral suggested by Choquet to represent the fuzziness in the evaluation process. This paper aims to develop the method for this evaluation from the viewpoint of mariner's operational stress using the fuzzy logic and Choquet integral. In this paper, Korean coastal area is divided into 8 sectors and evaluated the priority for the needs of coastal VTS and navigational aids.

The port of Mokpo operates the largest number of coastal passenger ships and routes in Korea. These coastal passenger ships pass through narrow channels in the south-west coast of Korea owing to the geographical effect. It is difficult to find a research for the safety of the marine traffic environment in the narrow channel used by coastal passenger ship. Therefore, in this study, the navigation safety of the target coastal passenger ship was analyzed in the narrow channel near the port of Mokpo using the Korea design standard for port and harbour facilities. As a result of the analysis, the width of the narrow channel between Maek-island and Dali-island is narrower than 1.5 times of the target ship's length over all, the degree of curvature of the narrow channel exceeds the standard value of 30°, and several fishing gears exist near the narrow channel. Finally, the following were suggested to improve the safety of navigation on the narrow channel: keeping one-way traffic during the day-time, and navigating through the designated fairway during night·visibility restriction·low tide.

2020년 AIS 자료와 해양용도구역 정보를 종합해 월별/해역별 주요 선박 통항로를 분석하고 우리나라 연안의 주요 선박 통항로 영역을 유효·비유효 구역으로 구분하여 향후 빅데이터 기반의 통합 항로 예측에 적용하는데 활용하고자 한다. 이 결과를 선박 해양사고정보, 해양에너지, 수산 등의 해양공간계획(MSP) 정보를 추가·분석할 예정이다. 나아가 국가어항을 중심으로 항만별 분석, 화물선·여객선·어선 중심의 선종별 분석 정보로 확대하여 빅데이터 기반의 항로 예측 기술의 입력자료로 활용할 예정이다.
