초록

항내 혹은 협수로와 같은 제한수역에서 근접하여 항해중인 두 선박간의 상호 유체력 및 모멘트가 선박조종운동에 상당히 크게 영향을 준다는 것은 잘 알려져 있다. 두 선박간의 상호간섭력은 종방향 거리, 횡방향 거리 및 두 선박의 속도의 함수로서 가정될 수 있다. 본 연구에서는 근접 항해중인 추월선박과 피 추월선박간의 상호유체력을 계산하고, 두 선박간의 횡방향 및 종방향 거리와 속도, 그리고 타 사용으로 인한 접근상황 및 충돌시간에 대해서 검토, 고찰하였다.

It is well known that the ship manoeuvring motion is greatly affected by hydrodynamic forces and moments acting between two vessels passing too close to each other in confined waters, such as in a harbour or narrow channel. This interaction between two vessels could be assumed to be the functions of the longitudinal distance, transverse distance and their speeds. The aim of this study is to calculate the interaction between two vessels passing close to each other on parallel courses by simulation, and to estimate the effect of rudder action and time at collision through simulation under the condition of various longitudinal distances and different speed-ratios of the two vessels.
