우리나라는 1993년 포항에 최초로 해상교통관제시스템을 최초 도입하여 현재 항만VTS 15개소와 연안VTS 5개소 등 총 20개의 관제센터를 운영하고 있다. VTS에 대한 시행부처는 허베이 스피리트호 오염사고, 세월호 사고 등 대형 사고가 발생할 때마다 변경이 이루어져 왔다. 현재는 해양경찰청에서 VTS 운영에 관한 전반 업무를 수행하고 있다. 하지만, VTS 소관 법령은 해양수산부가 관장하고 있으며, 항만VTS의 경우 같은 업무를 수행함에도 해양경찰청 일반직공무원과 해양수산부 파견 일반직공무원으로 소속이 나누어져 있으며, 연안VTS는 대부분 경찰공무원이 업무를 수행하고 있어 소속과 신분에 있어서 일원화 되어 있지 않은 상황이다. 일원화되지 못한 소속 및 신분은 인력관리, 사고대응력, 관제역량 강화에 제한이 되고 있다. 이에 본 연구에서는 VTS 업무를 효율적으로 운영하기 위한 방안을 검토하기 하고자 한다. 이를 위해 내 외부의 환경을 분석하고 소속 및 일원화의 장단점을 분석하였다.

VLCC에 의한 SK에너지 울산CLX와 인천CLX의 일원화된 효율적 원유 수급체계에 따른 물류비용의 절감, 이에 따른 국가 산업 경쟁력확보 및 항만경쟁력 강화를 위한 고도화 사업의 일환으로 고부가가치 선박인 VLCC가 인천항에 처녀입항하게 되었다. 이로 인한 해상교통관제센터(VTS)의 안전대책이 요구되어 비교적 통항량이 많고 항로길이가 긴 인천항의 VLCC운항 계획에 따른 해상교통 혼잡도 등, 다각적인 통항 안전성 및 VLCC 입출항에 따른 타 통항선과의 항행안전 관계등을 점검하여, 계속적인 VLCC 입항에 따른 항행 위험성을 파악하고, 앞으로의 인천항만 안전을 위한 통항안전관리대책을 모색하고자 한다.

To assess the risk of marine traffic environments, with high confidential level, the risk factors comprising it should be identified and the risk acceptance criteria should be also provided. Furthermore, the relative importance of each risk factor(the weight of each risk factor on total risk) should be analyzed because the risk is expressed as the sum of risk factors comprising it. The twenty kinds of risk factors and its assessment criteria were suggested for the domestic marine traffic environments by an examination of the existing risk assessment models on the previous studies. The relative importance of each risk factor was also analyzed through the questionnaire using analytic hierarchy process by the marine traffic experts on the same studies. Based on these previous studies, the risk was evaluated at the port of Mokpo and its approaches on this study. The port of Mokpo and its approaches were divided into four sectors for the comparative evaluation, the result of the comparative evaluation on four sectors showed that the risk of the Jeongdeung-hae passage is the highest due to higher risk level of some risk factors(water movements, complexities, tug boats, pilotage, VTS) than the other sectors. The result of this evaluation is in accord with the analysis results of the other studies using various qualitative or quantitative risk analysis methods at the same sea areas.

An estimation algorithm of collision risk among multiple ships has been developed in order to reduce human error and prevent collision accidents. The algorithm is designed to calculate the collision risk among ships based on Fuzzy theory by using AIS data as traffic information. In this paper, to validate the algorithm, the AIS data of actual collision accident, which occurred between a product carrier and a cargo carrier in Busan harbor in 2009 are collected. The replay simulation is carried out on the actual AIS data and the collision risk is calculated in real time. In this paper, the features of the estimation algorithm of collision risk and the results of replay simulation based on AIS data of actual collision accident are discussed.

Digital twin technology is used in various fields as a method of creating a virtual world to minimize the cost of solving problems in the real world, and is also actively used in the maritime field, such as large-scale systems such as ships and offshore plants. In this paper, we tried to build a digital twin of coastal waters using a ship-handling simulator. The digital twin of the coastal waters developed in this way can be used to safely manage Korea's coastal waters, where maritime traffic is complicated, by providing a actual maritime traffic data. It can be usefully used to develop and advance technologies related to maritime autonomous surface ships and intelligent maritime traffic information services in coastal waters. In addition, it can be used as a 3D-based monitoring equipment for areas where physical monitoring is difficult but real-time maritime traffic monitoring is necessary, and can provide functions to safely manage maritime traffic situations such as aerial views of ports/control areas, bridge views/blind sector views of ships in operation.

Marine traffic management could be defined as the implementation of managerial technical measures to improve vessel traffic safety. The managerial elements of vessel traffic management for ports and harbours or narrow channels include the total amount of traffic control, the vessel traffic separation scheme, speed restriction, traffic control by signals, the navigation information service and so forth. This research aims to quantify how much the traffic separation schemes(TSS) contribute to the alleviation effect of ship handling difficulty and to propose a design standard when the individual management measure is applied in an actual waterway. Traffic separation schemes have now been established in most of the major routes and congested waters of the world, and the number of collisions and groundings have often been dramatically reduced. In this part, the relationship between the alleviation of ship handling difficulty and the reduction of encounter figures among ships is quantitatively clarified by applying the ES model. As results of simulation analysis, it is recognized that a traffic separation system is most effective in the case of narrow width and heavy traffic volume. The centre buoy installation reduces about 1/4 of the alleviation of ship handling difficulty, TSS establishment 1/3, and design change to one-way traffic from two-way traffic reduces 1/2.

At the adjacent sea area of Busan Central Wharf, a variety of vessels, such as middle-large passenger ships, small fast sailing ships, container ships, cargo ships and working ships as well as small miscellaneous vessels are freely sailing comparatively without special steering and sailing Rules and marine traffic control because exclusive wharfs in accord with their purpose and use have been arranged in each wharf. In this research, we analyzed traffic stream and navigational characteristics of main traffic route based on statistics and distribution of tracks by ship's type and tonnage of the passing vessels after conducting marine traffic survey twice using exclusive software by targeting the sea area during the period of time. We examined the traffic safety of the passing vessels by classifying the sea area by each function based on the analysis about this traffic situation, and analyzing the effect by designating 'Buknea passage'. We also studied the plan for the effective rearrangement of Central Wharf considering basically the traffic safety oif arrival and departure in a point if view of navigators.

최근 국내 고층건물에서 비상훈련이 실시되었고, 이 훈련은 사전 예고한 상태로 화재발생 사이렌과 함께 정해진 시간에 대피를 완료한 사람은 약 20%에 머물렀다는 소식은 우리나라의 안전 불감증의 여전함을 절실히 보여주고 있다. 한편 해상에서는 지속적인 지진 발생 및 지진 발생 회수 증가, 지진 강도도 높아지고 있는 등 지진재해 발생가능성이 높아지고 있지만, 이에 대한 선박 피난에 대한 구체적 대응책 마련은 거의 없다고 할 수 있다. 이러한 해상 상황에서 가장 중요한 역할을 하여야 하는 VTS(Vessel Traffic Service, 해상교통관제)의 의미의 재정립이 필요한 시기이다. 2011년 3월 발생한 동일본 대지진 재해사례의 교훈을 중심으로 한 지진 재난시 우리나라 VTS 대응방안에 대한 제언을 통하여 재난 안전 확보의 가반을 마련하고자 한다.

해상에서는 도로가 아닌 해상 위라는 환경 때문에 음주단속을 실시하여 음주운항을 예방하기엔 어려움이 존재한다. 원거리로 신체정보를 보낼 수 있는 음성을 통하여 음주단속을 한다면 거리가 얼마나 떨어져 있더라도 실시간으로 측정이 가능하다. VTS 무선 교신 환경을 이용하여 음성을 통신할 때도 무선 환경이 고르지 못할 경우에 클리핑이 일어나 음주가능성 판단율이 저하될 수 있다. 따라서 본 논문에서는 음성신호가 왜곡이 되어 음주 가능성 여부의 판단율 오차를 줄이기 위해 신호를 보상하는 방법을 제안하였다.
