Abstract The results of previously performed studies are summarized, and a methodology for estimating the lifetime consumption of fire tankers is presented. The proposed methodology takes into account the specific features of the practical operation of a fire truck, as well as its integral part — the tank, which has a significant impact on the loss of the lifetime of the vehicle as a whole. The methodology combines computational and statistical methods, and also develops an approach based on taking into account two interdependent factors: mileage and operating time. In combination, this makes it possible to differentially determine the lifetime consumption of fire tankers, taking into account the weighted average consumption of the lifetime potential of their main components. At the same time, to the known five typical groups of the main parts of the vehicle, which have a similar nature of lifetime loss depending on mileage (conditions, nature of loading and damage processes) and operating time, in the case of a tanker truck, it is proposed to add another characteristic group, tanks, using a dependence for assessing its lifetime, taking into account the lifetime consumption for corrosion wear. An example of calculating the lifetime consumption of a fire tanker is given. The results obtained show values corresponding to the actual processes of obsolescence. Scope of application of the results obtained is: assessment of the condition of a fire truck and its tank after long-term storage; extension of the operation of a fire tanker after the expiration of the established service life; extension of the service life after major repairs; extension of the service life after the main lifetime work out; decision on the expediency of repair or decommissioning of a tanker truck.
