Abstract: Monte Carlo simulations have proven to be an effective and useful tool to deal with probabilistic damage stability computations. They can deliver important information on safety levels of ships as well as of regulations on one hand and on the other hand they are much faster in application compared to the manual computation method due to the fact that damage generation and stability analysis can be completely automated. For this reason, such kind of methods are applied during the early design phase of ships. Despite the mentioned advantages of the underlying principle, the method has some methodological drawbacks which prevented until now the generation of documents for the statutory approval of the damage stability results. This is due to the fact that the approval process of damage stability requires the presentation of information which is difficult to obtain from a pure Monte-Carlo simulation technique. This paper describes which steps are necessary to obtain the missing information from a kind of reverse engineering method and how the identified problems can numerically be solved. As a consequence, this efficient simulation technique can now be applied during the whole design phase until the delivery.
