A Study on Rescu Technique and Safe Tow of Damaged Ship(4) - Dynamic Stability of Damaged Ship in Beam Wind and Waves -

손상된 선박의 구난 기술 및 안전 예항에 관한 연구(4) - 손상된 선박의 횡풍.횡풍중에서의 동적 안전성 -

This paper presents a brief outline of dynamic stability of damaged ship in rough, beam wind and waves. The one degree-of-freedom, linear roll equation is adopted with the effects of damage fluid and external forces, but without the effect of sloshing. We evaluate the dynamic stability in terms of capizing probability based on energy balance mechanics and risk analysis , the method of which was proposed by Umeda [2] to the high speed crafts. As a result, we can predict the dynamic stability quantitatively according to sea state , operating and damage conditions.
