A Framework for Probabilistic Damage Stability Assessment of Passenger Ships Considering Collision, Grounding and Contact Accidents

This contribution provides an overview of the framework implemented in the joint industry project “eSAFE—enhanced Stability After a Flooding Event” for probabilistic damage stability assessment of passenger ships. The framework takes into account collision, bottom grounding and side grounding/contact accidents, by providing specific corresponding attained subdivision indices. Damage cases and associated flooding probabilities are determined through a common automatic non-zonal approach, while the post-damage survivability metric is based on the SOLAS “s-factor”. The framework is intended for practical application and is generally consistent with existing SOLAS probabilistic damage stability regulations. To support designers in the application of the framework, a specific software functionality has been developed, tested and applied. Some example applications of the framework are reported.
