| Research Abstract |
Firstly, by applying a physical model which is based on the model test, a estimation method for wave loads of the damaged ship under towing is developed.
Secondly, mathmatical model for probability of capsizing that takes the probability of structural failure of ship hull is also developed. In this study, ultimate strength is assumed as a threshold value for a structural failure.
Finally, by the combination of those probability, conditional probability of capsizing and failure was developed. Furthermore, series computation of those probability was carried out to find the dominant probability in the comprehensive assessment.
