To study the motions and flooding process of a damaged cruiser, a series of experiments and numerical calculations have been performed in calm water and in waves. Two damaged scenarios are selected to investigate effect on the motions and flooding process; midship section and fore section. The results of the experiment, relating to the quasi-static numerical model and the quasi-dynamic numerical model are compared . Numerical simulations are then conducted using quasi-static and quasi-dynamic models. The quasi-dynamic model adopts the mass-spring system for internal water motion description and the model considers the dynamics of free surface as ship motion. The flooding water with free surface in midship section changed the heave and roll of the cruiser and roll RAOs in waves because the center of flood water amidships locates on the starboard side and the flooded water with large free surface area in the upper compartment generates sloshing flow. The developed quasi-dynamic model reproduces these flooding water motion in calm water and waves.
