파랑중 손상선박의 유체동역학 성능 평가

Abstract

Importance of performance evaluation of a damaged ship in waves has been widely recognized from experiences on accidents of damaged ships which resulted in loss of passengers, crews and ships. Requirements for the evaluation methods for hydrodynamic performance of a ship in damaged condition are time-effectiveness and physically reliable modelling which are essential for finding solutions of highly complicated problems under emergency situations. Three different kinds of numerical analysis methods are investigated to evaluate the performance of damaged ships for various aspects of design and analysis purposes. Numerical and experimental examples are shown for typical behaviours of damaged ships such as free-roll-decay motion, coupled roll motion with flooded water, time-to-flood and wave loads on damaged ships
