Abstract
Safety of life at Sea has been emphasized for a long while. Since International Maritime Organization published regulation referring to evacuation analysis for passenger ship, it is essential to implement simulation about egress route distribution and safety of passengers. Although ships are for carrying goods mainly, maritime tourism has sprung up recently such as luxury cruises, as the result, it becomes more and more important to arrange egress route distribution that leads to efficient evacuation for passengers under emergency conditions.
AENEAS was used for the following simulation about evacuation and analysis for passenger ship. Due to the limit of each exit, it is essential to assign specific rooms to appropriate exit. In this case, potential is the key to determine the exit which each room prefer to go, furthermore, Greedy Algorithm is applied to reach the result. The other way to assign exit is taking account of conflict of agents. After assigning rooms to each exit and distributing egress routes among all cabins, simulation was implemented under static condition. Afterwards, simulation under periodical ship motion was implemented to observe what happens when the environment became more dangerous for passengers. The assumption and environmental parameters all correspond to “Guidelines for Evacuation Analysis for New and Existing Passenger Ships”. It seemed that the result of simulation comply with the guideline mentioned which means that the current egress route distribution and total travel time are literally proper. Although the condition with periodical ship motion takes more travel time than static condition, it still comply with the guideline. And the results show that restricted capacity for exits of Greedy Algorithm is more suitable to evacuation simulation of partial area, on the other hand, assign exit by considering conflict of agents is more proper to simulation of all passenger decks.
In the future, ship damage condition could be considered for further evacuation simulation. When ship is tilting, as freeboard immersed and water flowing into cabins, the general environment becomes more harmful for passengers. In this way the evacuation time should be less and condition becomes more dangerous than the guidelines published by IMO, it will reflect the reality of shipwrecks.
