Object and purpose of research. The object of the study is polymer composite materials (PCM) used for manufac-turing hull structures of ships and vessels. The main purpose is to find the ways of fire protection of ships and vessels built from these materials. Materials and methods. The results of experimental studies and standard tests on the fire resistance of PCM structures, as well as methods of heat and mass transfer processes simulation in ship premises during fires, were used to determine the thermal characteristics affecting these structures. Main results. The ways of improving the fire safety of ships and vessels with PCM hull structures are determined. The list of problems to be solved in this area is outlined. Also this study has recommendations to improve the fire protection of the ships being designed, under construction and in operation. Conclusion. The structural PCM used in indigenous practice does not meet the current requirements of the International Maritime Organization (IMO) for Maritime Safety for fire protection of high-speed vessels and the requirements for fire protection of Navy ships. Ships that are in service and built using these materials do not provide additional measures to reduce their fire hazard. Fires on such ships can lead to disastrous consequences. It is necessary to solve this problem as soon as possible. The recommendations proposed in this paper on how to solve it, based on a large amount of experimental research, and they have great practical significance.
