| Research Abstract |
For the rational evaluation of a residual strength of a damaged ship in waves, a study from computation of wave loads to evaluation of probability failure was conducted comprehensively.
A method for the measurement of wave loads in a tank test and a computation method were developed and validated. An evaluation method for the structural strength of a damaged ship is also developed. Furthermore, by the combination of these methods and the First Order Reliability Method, FORM, an evaluation method for a failure probability of a damaged ship was developed.
