Unlike land based transportation/industry, ships sail in mid-ocean with very little or no access to external helps and supports to deal with fire accident on board. Fire is a significant threat to safety of ship, lives of the personnel onboard and cargo she carries. Fire on ships can also cause heavy damage to the marine environment. In case of fire initiation if the containment of fire is not efficient then it will not provide adequate time to make use of internal appliances or any possible external support to extinguish fire and result in a severe damage. So, it is important to predict the growth of fire and associated smoke propagation for all possible types and sources of fire. The prediction of fire growth and smoke propagation may be achieved by exercising simulation techniques. The provision of the prevention of fire propagation as prescribed in the presently applicable rules and regulations need investigation from the first principle. Also, the present rules are not explicit about the fire scenarios which have or have not been considered in the development of the rules. For the analysis of fire growth and smoke propagation in order to develop efficient evacuation process onboard a ship, there is a need to study the scenarios with the help of fire simulation techniques. As an ongoing research work, in this paper, the applicability of fire modeling techniques — Field Modeling and Zone Modeling, are investigated and a comparative study is made between both the techniques. The results are explained wherever necessary and future scope of the work is identified. An attempt has been made to define the accuracy level needed for fire simulation tools, considering present state of the art and limitations.
