In order to investigate the behaviour of permanent deflection of deck plate of patrol ships, the t-requency distribution of deflection and its change were measured over a long period. The allowable limit of initial deflection and the collapsing strength of ships were calculated as well.
To examine the stress of patrol ships among waves, the actual ship experiment was carried out, and the statistical values of ship stress were calculated.
