세계 교역량이 증대되면서 해상 교통량은 계속 증가하고 있으며, 후발공업국에서는 새로운 항만의 건조가 활발하게 이루어지고 있다. 우리나라의 경우에도 연안공업단지의 개발과 서해안 개발의 일관으로 기존 항만의 확충은 물론 신항만 건설이 추진되고 있다. 그러나 항만내 계류된 선박의 운동특성을 밝히는 이론이 아직 정립되어 있지 못하여 이에 대한 연구가 절실히 요구되고 있는 실정이다.(중략)

울산항은 국내 최대의 액체화물 거점항만으로 지속적인 물동량 증가에도 불구하고 다른 무역항에 비해 정박지가 협소하고 날씨의 영향으로 해양사고 발생 개연성이 매우 높은 실정이다. 울산항의 지형학적인 특성과 선박 교통량을 고려하여 울산항 정박지의 전반적인 실태를 분석하고, 정박지 투묘 선박의 안전성 확보를 위해 효율적인 정박지 운영 및 개선방안을 제시하였다.

Recently Bridges crossing waterway are constructed in navigable waterway, so marine accidents near bridges navigable waterway often occurred bemuse that has affect dangerous element for. This paper analysed the necessary environmental factors to navigate safely near bridges and how to set up the environmental factors. Marine accidents elements occurred near bridges relate to span of bridge, size of navigating ship, length of straight way and traffic volume except mistake of mariners. As results of marine accident parameter analysis, Span of bridge is necessary more than 300m at least based on marine accident's analysis, and in case of more than ship's Length 150m, span of bridge is necessary more than 500m, $3{\sim}4L$(L; Ship's Length). Length of straight way before bridge is necessary more than 8L to minimize the marine accident.

우리나라 해역에서 선박의 대형화, 고속화와 선박교통량의 증가 및 항만과 해양개발 등으로 해상교통 환경은 급속하게 변화하고 있으며, 항로의 좌 우 측방 한계 표시, 항행위해요소의 표시 등의 용도로 사용되는 부표류는 항만, 연안해역 및 내륙수로에서 통항 선박의 안전을 위하여 그 수요가 점진적으로 늘어나고 있다. 변화하는 해양교통 환경에 능동적으로 대처하고 부표관리 업무의 효율성을 증대하기 위하여 경량화, 내부식성, 저비용 등 장점으로 정온도가 유지되는 항내나 내륙수로 등에서 국제적으로 항로표지용 부표로 이용되고 있는 플라스틱 부표의 국외 개발 동향, 제조 방법 및 시제품의 특성 평가를 통한 기술 향상 방안에 대하여 기술하였다.

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.

As the marine transportation has increased, the safe maneuvering system has been required. SOLAS obligated regulations for carrying AIS(Automatic Identification System) onboard. This system provides navigational information including identification, classification, position, a ship's course and voyage status from own vessel to ground and other vessels. Being utilized in the most development of application service for safe maneuvering, they are to be managed systematic. In this paper, we introduce a database system to manage the voyage status and navigational information of AIS message. It is classified by static or dynamic. An electronic navigational chart display system is implemented to verify the design.

This paper estimated the future traffic volume incoming and outgoing in Incheon port, and analyzed the value of information serviced by tidal current signal operation center in Incheon. The cargo traffic in 2020 will increase twice as much as in 2005 according to the national ports basis plan. The maritime traffic will increase greatly consequently. Also, MOMAF has operated tidal current signal operation center to prevent marine accidents caused by current influence on vessels navigating through Incheon. However the quantitative effect is not known because there is no analysis about its value. Therefore the value of information serviced by tidal current signal operation center in Incheon was calculated with contingent valuation method(CVM), and the information value was analyzed considering future traffic in this study. Thus, the annual information value was calculated at about $170{\sim}280$ million won, considered traffic volume using the information of tidal current directly in 2020 since 2006.

해상 교통량 증가에 따른 연안해역 해상교통밀집도가 증가되고 있다. 그러므로 해상교통안전관리를 위해 실 해역의 해상교통패턴을 파악하여 해상교통지수를 평가하는 것이 중요하다. 분석대상해역의 실제 선박위치, 속력, 침로를 고려한 CPA-TCPA분석은 통계적인 선박데이터에 의한 분석보다 해당해역의 실제적인 VTS영향 등 교통환경을 반영한다. 본 연구에서는 횡간수도와 완도진입수로의 항로가동률을 분석하고, 해당 해역에서 교차되는 선박들의 CPA, TCPA 등을 분석하여 해상교통안전지수를 평가하고자 한다. 또한 산출된 해상교통안전지수를 해당 해역의 통계적인 해상교통안전지수와 비교 및 분석하고자 한다.

Traffic risks in fairway and harbour area increase lately according to be a sharpe change of ship's size and speed. It becomes hot issue to design a fairway, which's width is important to lower traffic risk and ensure navigational safety. The current design making a fairway and width do not focus on maneuvering motion of a large ship, but traffic risks are clear on reflecting the design of fairway, specially on width. To contact with these problems, this research proposes how to determine fairway' width in consideration of traffic volume. it suggests several situations of marine traffic congestion as like narrow channel and harbour area. here uses 162 simulations in MTS Ver.1 developed. Acquired simulation's results, environmental stress dates, figure in a model that relates with required fairway' width and allowable traffic volume. In added, suggested model compares current design with an width.
