This article addresses the problem of the low effectiveness of using primary fire extinguishing equipment on ships, which in turn leads to the rapid development of fire, crew fatalities, and vessel loss. The authors propose a different approach to the parameterization of fire extinguishers, namely, equipping protected facilities based on the extinguisher's heat absorption capacity, considering the specific fire load of the facility's compartment. The article presents experimental data from numerical modeling of fire development in shipboard compartments using the PyroSim software, based on reference data and the actual fire load provided by shipbuilding plants. The analysis of the heat release rate data confirmed that in the initial stage of fire development, the growth in heat release rate occurs uniformly, regardless of the area of the compartment where the fire is developing. Based on the experimental data, it is necessary to classify the compartments of a protected facility according to the thermophysical characteristics of the fire load and the extinguishing agent. This approach will enhance the effectiveness of fire extinguisher use on ships, thereby reducing the number of casualties and minimizing material and environmental damage.
