This paper presents the results of an investigation into the structural survivability of a modern cruise liner in a flooded and heeled condition after collision damage. In the intact condition these ships are typically loaded in a hogged condition, where the upper decks are in tension and the bottom and lower hull are in compression. In the case of a potential midship flooding casualty following a collision, the weight of the flooded water could put the ship in a sagged condition with the upper decks in compression. The structural survivability in flooded and heeled conditions is assessed for several damage scenarios with wave loading included. The analysis confirms that this ship has adequate strength to withstand the loading in these cases. Comments are also made on possible effects of local load contributing factors. A typical midship section is studied. This midship section is generally applicable between frames 100 and 180 between 0.28 LBP(length between perpendicles) and 0.51 LBP forward of AP( aft perpendicle). Three sample intact loading conditions and three final stage flooding scenarios forming a matrix of nine damage conditions are statically evaluated (in still water plus static hog and sag waves) to study a number of combinations of loading and damage scenarios. This study demonstrates that the structural capabilities ofa large modern passenger liner can generally withstand the loading of a heeled, damaged ship in a moderate seaway.
