Simulation Analysis of Fire safety System Onboard Indonesia Ro-Ro PaxCrossing Ferries

Fire onboard ro-ro ferry usually claims a great number of casualties. in indonesia 41% of major marine accidents were fire accidents. victims of ferry fire accident are usually due to smoke, heat, and low visibility. the research is aimed to simulatethe flow of heat and smoke during a fire from car decks of the ferry to passenger decks and how the fire safety systemsprovide sufficient time for the passengers to escape from the affected areas. fire dynamic simulator v5 (fds v05) software was used in three different fire scenarios namely without sprinklers; with sprinklers but without smoke exhaust and fresh air supply fans; and with sprinklers, smoke exhaust and fresh air supply fans. it is proven that water sprinklers could suppress the distribution of heat, and smoke exhaust and fresh air supply fans have contribution in maintaining the visibility.
