The results of the analysis and generalization of data on the safety of marine equipment during navigation in the period from 2012 to 2021 presented. Particular attention in the analysis of data paid to the frequency of emergencies at various marine facilities. Allianz Global Corporate & Specialty's data used to identify current trends in ensuring security in the transportation of goods. It been established that the three main causes of the loss of marine equipment (85 % of all losses) over the past decade include emergencies associated with flooding (~55 %), grounding (~20 %), fires and explosions (~10 %). It shown that the greatest losses of sea vessels because of emergencies (accidents) are typical for the water areas of South China, Indochina, Indonesia and the Philippines. The analysis and generalization of static data on the state of navigation safety made it possible to identify current trends in the field of tanker transportation safety.

Leaks of liquid and gaseous hydrocarbons from pipelines and equipment of transportation, storage and processing facilities lead to fires and explosions. Often the cause of hydrocarbon leaks is corrosion of metal structures, leading to their depressurization. To increase the durability of metal structures, they are protected with anticorrosive coatings. The protective ability of the anticorrosive coating is determined by its continuity (defect). The prediction of the continuity (defectiveness) of the anticorrosive coating is carried out using empirical exponential or power expressions. The disadvantage of these expressions is a large number of hard-to-determine factors and empirical coefficients. An empirical expression is given to assess the defectiveness of the anticorrosive coating at the current time. An empirical expression is proposed for predicting the operational continuity (defectiveness) of an anticorrosive coating, taking into account the production (initial) defectiveness, the permissible service life and the aggressiveness of the environment. It is shown that the aggressiveness of the environment significantly affects the continuity (defectiveness) anticorrosive coating. The results of forecasting the continuity (defectiveness) of the anticorrosive coating are compared according to the currently used expressions and according to the proposed expression.
The obtained results of forecasting the continuity (defectiveness) of the anticorrosive coating are close. The empirical expression proposed for predicting the continuity (defectiveness) of the anticorrosive coating is promising for practical application.

Global geopolitical and socio-economic changes taking place in the Russian Federation in recent years have led to significant changes in the number and structure of categories of persons held in various institutions of the Federal penitentiary service of Russia, which requires the search for new economically sound ways to optimize the costs of ensuring their targeted functioning and maintenance. The analysis of scientific, technical and regulatory domestic and foreign sources and documents has shown that one of the main directions of solving this problem can be the creation of enlarged institutions of the Federal penitentiary service, combining in a limited area a large number of multifunctional complex-structured objects interacting with each other with
a special regime for the stay of numerous groups of people in them [1–4]. According to formal signs, such objects belong to the category of objects with a mass stay of people and require the implementation of a set of special measures to reduce the risks of emergencies and fires.
The purpose of the work is to search, substantiate and develop new more effective means and methods of reducing the risks of emergency situations at promising facilities of the united institutions of the Federal penitentiary service of Russia.
The methodological basis of the work was analysis, synthesis, statistical, system-structural methods, forecasting method. As a result of the conducted research, the need for the transition of the Federal penitentiary service of Russia to joint type institutions to develop new methods
for reducing the risks of emergencies and fire risks in them based on digital models and BIM technology is justified.
The article suggests approaches to reducing the risks of emergencies at promising special-purpose facilities of the Federal penitentiary service of Russia on the basis of intelligent consideration of functional features, structural and space-planning solutions of their individual components, as well as continuous monitoring of changes in fire load using digital models. The possibility of implementing these requirements within the framework of the development and implementation of a hardware and software complex of an intelligent warning system and evacuation management using digital BIM modeling technology is shown.

The issues of research of fire-hazardous modes of operation of the electric network of the car are considered. Emergency modes of operation of the electrical elements of the car can lead to a fire with varying degrees of probability, depending on the service life of the machine and external influences. The article proposes a software package based on the use of stochastic calculation methods. This will allow you to get more specific information about the likelihood of a fire-hazardous emergency mode in the vehicle's electrical network, depending on external factors and its service life. It is proposed to use the results obtained for effective management of prevention and prevention of fire-hazardous modes in the vehicle's electrical network. The relevance of such information increases in the case of car parks, where the degree of operation, the brand of the manufacturer, the year of manufacture and the scheme of use of electrical elements of each car differ.

The possibility and expediency of evaluating the properties of the flame retardant coatings has been exemplified by the chlorine-containing flame-retardant composition according
to the criteria quantitatively characterizing the process of coating intumescence, i.e. intumescence ratio, mass variation, density and porosity of the foamed coke formed as a result of heating the samples. The degree of intumescence and changing in mass of the coating samples have been determined according to the conventional techniques; density and porosity variations of coke have been measured by the computation based on the experiment data. The curves of dependence between the intumescence parameters of coating and the temperature have been derived. The results of the investigation showed that these parameters may be applied as the evaluation criteria for comprising the formulae and further optimization of coatings properties designed to protect building constructions in conditions of extreme heat exposure.

The issues related to modeling the cascade development of emergency situations, in particular, fires in parking lots, are considered. It is shown that when a car catches fire, both it and neighboring cars can suffer. It is shown that the damage from the fire can be of a cascading nature and will be determined by how soon the extinguishing and restoration of the normal functioning of the parking lot will begin – how quickly repair and restoration work will be carried out. The assessment of the probabilities of the parking lot conditions «normal functioning – fires – extinguishing – restoration» was carried out in two ways – using the methods of the theory of Markov processes (with discrete time) and adapted queuing systems (with continuous time). Analytical expressions are obtained and examples and comparison of the results of estimating the probabilities of states obtained in two ways are given.
