Abstract
This paper provides an overview of the work carried out to validate a time domain simulation program for a damaged frigate with cross flooding arrangements. This concerns roll decay tests in calm water and the dynamics in regular and irregular waves. To assess the survivability of this frigate for several damage scenarios in a variety of sea states, a probabilistic 'operability-type' of analysis has been applied on the basis of extensive numerical simulations. To illustrate the methodology, three different mission requirements have been investigated and compared for the damage scenarios. The results suggest that it is feasible to study the influence of mission requirements on damage survivability in a quantitative sense.
