New cruise passenger ships are trending towards “gigantism”, consequently together with size also the number of passengers and crew increases. For this reason, international regulations known as “Safe Return to Port” are more and more aimed at upgrading intrinsic ship safety in event of fire or flooding. When the accident exceeds a fixed threshold, a ship safe evacuation must be guaranteed. To this end evacuation analysis becomes a primary task in passenger ship design, since the early stages. According to IMO Regulations, evacuation analysis can be tackled in two different ways: a simplified method or an advanced one. The latter involves the use of specific certified computational tools. In this work an advanced evacuation analysis for a cruise passenger ship with about 3600 persons on board is presented.
