갑판타입수의 유입에 따른 Ro/Ro선 안정성 연구

초록

Intensive experimental investigations were carried out to provide informations of the effects of inflow on the rolling characteristics and stability of shipe, which becomes great concern in relation to ship's capsizing. A series of systmatic experiments have been performed considering the effects of combined motions of roll-heave-sway and relevant parameters, such as roll angle and period, tank water height etc. To accomodate this type of experiments with 3-degree of reedom of motion, a bench tester has been developed and verified using existing data. Also theoretical application of anti-roll tank has been incorporated to support the process of investigation. A model of Ro/Ro ship is used in the present study as this type of vessels, as well as fishing vessels with large open decks, can loose stability rapidly when there is inflow on decks.
