Research on damage stability and invincibility is a valuable source of knowledge of behaving a ship while flooding its compartments. In the paper, a short deser iption of accidents and damages of Polish warships taking place in 1985-2004 is presented. The time when compartments are flooded (tf) is one of the key elements which have influence on a rescue action. The knowledge of the time mentioned is very important for a commanding officer making decisions while flghting for invincibility and survival of the ship. To provide the information about the time tf of a ship type 888 a new method was designed. The method was tested experimentally and results of the tests are presented in the paper. In the experiments, the flooding process of compartments was simulated. The flooding time calculation of damaged compartment, according to the method des er ibed in the paper, is verifled on the laboratory stand bed. Thanks to a suitable construction and new concepts applied for the station, research on the ship reaction and position in the failure situations is possible. The next part of research was carried out on the laboratory stand bed, where the flooding time of damaged compartment of warship model was measured. The results of the experiments can be a base to define general rules to make proper decisions during the process of damage control.
