  • Up to now a lot of the study on ship collision avoidance systems has proceeded actively. However the frequency of ship collision accidents didn't decreased. If there is collision risk in close quarters situation none the less manouvering ship for collision avoidance according to the system, only use of TCPA and DCPA as input factor for collision risk decision is not useful to avoiding collision action. For the recent 5 years by the analysis of first observation distance about approaching ship in domestic collision accidents, nearly $45\%$ of accidents is close first observation less than 2 miles. Therefor it is essential part for safety navigations to study for collision avoidance action in close encounter. In this paper, as foundation study of supporting collision avoidance manoeuvring for navigators, we proposed ship collision avoidance support model in close quarters situation through analysis of collision accidents for effective getting rid of the causes.

  • Up to now a lot of the study on ship collision avoidance systems have proceeded actively. However the rate of ship collision accidents hasn't decreased yet. If there is collision risk in close quarters situation in spite of maneuvering ship for collision avoidance according to the system, only use of TCP A and DCP A as input factor for collision risk decision is not useful to avoiding collision action. For the recent 5 years by the analysis of first observation distance about approaching ship in domestic collision accidents, nearly $45\%$ of accidents is close first observation less than 2 miles. Therefore it is essential part for safety navigations to study for collision avoidance action in close encounter. In this paper, as a fundamental study of supporting collision avoidance maneuvering for navigators, we proposed ship collision avoidance support model in close quarters situation through analysis qf collision accidents to effectively get rid of the causes.

  • In this paper, as a fundamental study of ship collision avoidance supporting system in close quarters situation, we propose ship collision avoidance support model for decreasing ship collision accidents those have occurred due to navigator's unsuitable maneuvering in close encounter. This model will effectively support maneuvering for collision avoidance through displaying the feasible area and the method of collision avoidance using own ship's turning characteristic about action of target ship's keeping course and velocity.

  • 하인리히 법칙에 따르면, 하나의 대형사고는 다수의 경미한 사고나 수많은 근접한 위험상황이 발생한 위치에서 발생할 확률이 높다. 해상교통상황에서도 양 선박이 충돌 위험이 있는 상황, 즉 근접사고 상황은 해상교통관련 대형 사고를 예방하는 관점에서 중요하다. 하지만, 아직까지 이러한 근접사고 자료는 VTS데이터 접근에 어려움, 관련 전문 기법 부족 등으로 수집 분석하는데 어려움이 있었다. 이에 본 연구에서는 해상교통 근접사고를 조우하는 선박간에 시공간적으로 충돌에 근접한 상황들이 발생하여 충돌의 위험이 일정한 값 이상으로 높아진 상황으로 정의하고, 2013년도 완도VTS 관제해역 해상교통 항적데이터를 적용하여 근접사고 통계를 분석하였다.

  • VTSO(Vessel Traffic Service Operator)는 양 선박의 충돌위험 정도를 판단할 때, 선박들의 침로와 속력, DCPA(Distance to CPA)와 TCPA(Time to CPA) 그리고 양 선박의 조우상황 등을 종합적으로 고려한다. 이에 본 연구에서는 VTS관점에서 선박충돌 위험도를 구하기 위하여 CPA에서의 양 선박 상대방위에 따른 조우상황 위험도와 선박의 길이를 고려한 양 선박의 범퍼영역에 대한 근접 위험도를 이용하여 두 선박의 다양한 교차상황에 따른 선박 충돌위험 값을 비교하였다.

  • Recently, ship collision accidents account for $20\%\∼30\%$ of domestic marine accidents, also have increased continually. In this paper, therefore we propose the development of Ship Collision Avoidance Support program for decreasing ship collision accidents. This program has been developed on the basis of CCAS-Model. A CCAS-Model has ship's maneuvering performance and has studied for the propose of supporting to avoid ship collision in close quarters. Besides, the program will effectively support maneuvering for collision avoidance through displaying the feasible area and the method of collision avoidance using own ship's turning characteristic about action of target ship's keeping course and velocity in various encounter.

  • In the maritime traffic environment, the near-miss between vessels is the situation approaching on collision course but collision accident is not occurred. In this study, in order to calculate the near-miss between navigating vessels, the discriminating equation using ship bumper theory and vessel position clustering methods are proposed. Applying proposed module to the vessel trajectories of the WANDO waterway, we assessment navigational risk factors of vessel type, navigational speed, meeting situation.

  • An acceptable proximity assessment collision probability is widely considered to be less than $10^{-4}$ in maritime traffic safety audit schemes. In the 1970s, Fujii, Macduff and colleagues introduced various models for collision probability of aberrancy in the community. Although existing studies ensured acceptable proximity collision probability, around $10^{-4}$, they were constrained by assumptions. A lack of support for the proximity probability criterion has been investigated in this study for practical use. The appropriate proximity probability for different size vessels in both straight and curved lanes has been analyzed based on GICOMS data. As a result, reasonable proximity collision probabilities were determined for various vessel traffic conditions. Accordingly, necessary improvements in the maritime traffic system have been suggested in consideration for various maritime traffic situations and conditions.
