두 조우 선박간의 충돌회피를 위한 분석적 기준에 관한 연구

Abstract

This study provides analytical criteria for collision avoidance between two encountering ships. The criteria determine the critical distance between the encountering ships at which evasive maneuvers must be initiated in order to avoid collision, given the relative motion and crossing angle between the two ships. Two different strategies for collision avoidance are addressed: speed change and heading change. A closedform solution for the critical distance was obtained for each strategy, which provides comprehensive criteria in terms of the maneuvering capabilities and geometric configurations of the encountering ships. To onstrate the validity of the proposedapproach, its results are compared with the rules mandated by the International Regulations for Preventing Collisions at Sea (COLREGS) by the International Maritime Organization (IMO).ollision, given the relative motion and crossing angle between the two ships.
