Abstract

If we were in a head-on or crossing situation with a target ship and did not know the target ship's intention to change her course, we might be confused about our decision making to change our course for collision avoidance and be in a danger of collision. In order to solve these problems, we need to develop an automatic system which enables mariners to easily detect a change in the target ship's course and efficiently avoid being on a collision course. In this paper, we proposed an early detection method on altering course of a target ship using the steering wheel signal. This method will contribute to the reduction of collision accidents and also be used to the VTS system and the analysis of marine accidents.

가까운 거리에서 상대선과의 마주치는 상황 또는 교차된 상황에서 상호 피항동작을 취하게 되는데, 상대선박의 변침의도를 정확히 파악하지 못해 서로 같은 방향으로 피항동작을 취함으로써 충돌위험에 처하게 되기도 한다. 항해사는 피항동작을 취함에 있어 시각에 의한 판단, 레이더 또는 AIS 벡터를 이용한 판단, 또는 VHF 통신을 활용하여 피항동작을 취하고 있으나, 레이더 및 AIS를 이용한 기존의 방식은 선박이 선회 후 선수방위가 표시되기 때문에 선회를 탐지하기까지는 상당한 시간이 요구된다. 따라서 조타기 작동 신호를 상대선박에 신속하게 전달하여 상대선의 선회의도를 보다 신속히 판단할 수 있는 선회조기감지 방안을 제안하였다. 이러한 방법은 상대선의 변침의도를 보다 신속하게 파악함으로써 선박 상호간 충돌예방에 효과적이며, VTS 시스템 및 해양사고 분석에서 활용이 가능하다.
