초록

본 논문에서는, 바지형 선박(barge-type vessel)의 묘박 상황에서 외력과 파주력의 물리적 관계 분석을 통해 묘박 안정성을 추정하였다. 선박에 작용하는 주요 외력인 바람에 의한 풍압력, 해류에 의한 유압력, 파도에 의한 표류력의 관계를 살펴보고, 태풍 내습 시 강도에 따라 선박에 작용하는 외력을 추정하였다. 또한 닻의 무게와 수심에 따른 파주력을 적용하여 바지형 선박의 묘박 안정성을 추정하였다.

Abstract

In this paper, the stability of the headstone was estimated through the analysis of the physical relationship between the external force and the field force in the situation of the headstone of a barge-type vessel. The relationship between the wind pressure by wind, hydraulic force by ocean current, and drift force by waves, which are the main external forces acting on ships, was examined, and the external force acting on the ship was estimated according to the strength during typhoon invasion. In addition, the stability of the headstone of a barge-type ship was estimated by applying the field force according to the weight and depth of the anchor.
