Abstract

The identification of the risk of collision between ships and objects is vital for achieving navigation safety. The purpose of this study is to analyze the phenomenon of ship domain invasion by breakwaters when ships pass between breakwaters. A method for evaluating the domain-invaded area under the conditions of the breakwater was developed. Next, experimental data were obtained and processed using the Automatic Identification System (AIS) of ships sailing near the breakwater at Busan Port to establish a ship domain that could be formed between the breakwaters. The ship domain was then constructed using Fujii's domain. Finally, the phenomenon in which the constructed ship domain was invaded by the breakwater was analyzed. Based on the experimental results, the domain of the ship invaded by the breakwater was identified.

선박과 물체의 충돌위험을 파악하는 것은 항해안전에 중요하다. 본 연구의 목적은 선박이 방파제 사이를 통과할 때 선박 도메인이 방파제에 의해서 침범당하는 현상을 분석하는 것이다. 연구방법은 먼저, 방파제가 주어진 조건으로 설계된 선박 도메인을 침범하는 영역을 평가하기 위한 방법을 제안하였다. 그런 후, 부산항 방파제 부근을 항해하는 선박들의 AIS(Automatic Identification System)로부터 실험 데이터를 획득하고 처리하여 방파제 사이에서 형성될 수 있는 선박 도메인을 구축하였다. 이 때 선박 도메인은 Fujii의 Domain을 이용해 구축하였다. 마지막으로, 구축한 선박 도메인이 방파제에 의해서 침범당하는 현상을 분석하였다. 실험결과, 방파제에 의해서 침범당하는 선박 도메인이 확인되었다.
