Abstract

To ensure the safety for vessels anchored in stormy weather, duty officer and VTS operator have to frequently check whether their anchors are dragging. To judge dragging of the anchored vessel, it is important for VTS operator to recognize the turning circle and its center of the anchored vessel. The judgement for the anchored vessel dragging can be made by using Radar and AIS. If it is available, CCTV or eye-sighting can be used to know the center of turing circle. However, the VTS system collects individual ship's dynamic information from AIS and ARPA radar and monitors of the anchored vessels, it is difficult for VTS operator not only to get the detailed status information of the vessels, but also to know the center of turning circle. In this study, we propose an efficient algorithm to estimate the center of turning circle of anchored vessel by using the ship's heading and position data, which were from AIS. To verify the effectiveness of the proposed algorithm, the experimental study was made for the anchored vessel under real environments.

정박중인 선박의 안전을 위하여 항해사, 선장 및 해상교통관제사는 항상 선박이 주묘되고 있는가를 확인하여야 한다. 정박선의 주묘판별을 위하여 VTS 관제사가 선회권과 그 중심을 인지하는 것이 중요하다. VTS에서 정박선 주묘여부 감시는 레이더 및 AIS를 이용할 수 있다. 또한 이용가능하다면, CCTV 영상이나 육안에 의한 관측도 이루어 질 수 있다. 그러나 VTS 시스템은 AIS 및 ARPA Radar로부터 수집된 데이터만으로 정박선을 모니터링하고 있으므로 정박지내에서 정박선의 선회중심을 알기가 어렵다. 본 연구에서는 VTS에서 AIS에 의해 수집된 정박 선박의 선수방위각과 위치데이터를 활용하여 선회중심을 추정하는 알고리즘을 제시하고자 한다. 알고리즘의 유효성을 확인하기 위해, 실 환경에서 정박한 선박에 대한 실험연구를 수행하였다.
