Software products of toxi+ line for calculation of accidents consequences and risk assessment
(2020) Agapov, A. A.; Sofin, A. S.; Sumskoy, S. I.; Сумской, Сергей Иванович
© 2020, STC Industrial Safety CJSC. All rights reserved.The first official version of TOXI+Risk software developed by STC «Industrial Safety» CJSC marked its ten years anniversary in April 2020. By now it become the main calculation tool for quantitative risk assessment of accidents and fire risk calculation at hazardous production facilities in the Russian Federation. TOXI+Risk is one of the products of TOXI+series, the works on which have been conducting since 1990s. The authors of the article recall the main milestones in the development of methodological and software support. Brief description is given concerning the current content of TOXI+ software series, the prospects for its development, and the activities conducted by STC «Industrial Safety» dedicated to the software. TOXI+Risk 5 software package is currently based on 26 calculation methodologies of Rostechnadzor, EMERCOM of Russia, Roshydromet, industry standards of PAO Gazprom and PAO Transneft, and it allows to simulate emergency situations asso-ciated with the cloud dispersion of hazardous substances, their combustion or explosion, fire spilled liquids, jet fire, BLEVE et al. TOXI+Water hammer software allows to simulate fluid flow in the pipeline systems of various configurations of the linear part, taking into account the difference in elevation of the route, the location and hydraulic characteristics of the elements of the pipeline system, including shutoff valves, pumps, safety valves and other devices, as well as estimate the mass of emissions of the transported substances during pipelines depressurization. TOXI+HAZOP software tool is designed to automate the paper-work during HAZOP sessions. TOXI+Forecast software allows to automate the actions of the dispatcher in an emergency: simulate accident scenarios with the spread of hazardous substances in the atmosphere when gas detectors are triggered, taking into account the current weather situation, inform the dispatcher and the interested parties about the forecast results (areas of exposure on the site plan, and poten-tially affected by them locations of people presence).

On some differences in the methodological approaches when modeling the parameters of pressure waves from combustion and detonation of fuel-air mixtures clouds
(2020) Agapov, A. A.; Safonov, V. S.; Shvyryaev, A. A.; Sumskoy, S. I.; Сумской, Сергей Иванович
© 2020, STC Industrial Safety CJSC. All rights reserved.The main regularities of the formation of shock air waves and air compression waves during combustion or detonation of fuel-air clouds are briefly considered in the article. Specific features are discussed related to the mathematical model of fuel-air mixture explosion, which is used in the Methodology for determining the calculated values of fire risk at the production facilities. The considered Methodology uses the same mathematical model as the corresponding Safety Guide on the assessment of the emergency explosion consequences approved by Rostechnadzor with some differences that are discussed in the article. The approach of the Methodology is based on the consideration of one-dimensional pressure waves that are formed in the atmosphere during detonation or turbulent combustion of spherical uniformly mixed clouds. For such processes the approximate dependences of pressure on the distance are built. The validity, accuracy, as well as the field of application of such dependencies are considered in the work. The conclusion is made about sufficient accuracy of the used dependencies and their good compliance to the current analogues and experiments, the provisions establishing the field of application of the extrapolation formulas for deflagration combustion are missing in the Methodology text. Due to this reason when calculating the situations are possible that at the same distance from the place of explosion of the clouds of fuel-air mixtures the pressure on the front of the detonation wave is significantly less (up to 7 times) than at the front of the deflagration waves. For deflagration combustion rates considered in the Methodology (up to 500 m/s), this result is incorrect. The reasons for this discrepancy are shown in the article. In Russia the Methodology is approved as the only document on which basis the fire risk indices are calculated, which in turn are one of the main criteria for making managerial decisions in the design and construction of industrial and social objects. It is shown that considered in the article specific features of the numerical explosion models of fuel-air mixtures cloud lead not always to the justified increase of the conservatism of the obtained results. It is noted that the indicated conservatism can be deleted by introducing appropriate limitations on the field of application of the corresponding approximations.

Parameters of Air Cylindrical Shock Waves
(2020) Sof'in, A. S.; Zainetdinov, S. K.; Agapov, A. A.; Sumskoi, S. I.; Сумской, Сергей Иванович
© 2020, Pleiades Publishing, Ltd.Abstract: In this paper, we perform a numerical analysis of the parameters of shock waves (SWs) generated during the expansion of cylindrical volumes of compressed methane. A single dimensionless approximation of the overpressure dependence on the distance is obtained using precise numerical solutions. The overpressure values in the SW are estimated for both the near and far zones. Comparison with previously developed similar dependences shows a higher accuracy of the proposed approximation, which allows predicting the consequences of accidents during the rupture of pipelines.

Calculation of the Indicators of the Risk of People Damage Considering the Variability of Their Presence in the Areas of Emergency Processes Impact at Hazardous Production Facilities
(2022) Sofyin, A. S.; Sumskoy, S. I.; Сумской, Сергей Иванович
Risk indicators, as a rule, are integral values for certain recipients (people, equipment, buildings, and structures) considering the frequency and degree of their damage as the result of exposure to hazardous factors of possible accidents with the release of hazardous substances. Risk indicators are used for assessing the efficiency of the compensatory measures, new industrial and fire safety requirements, or the risk of deviations from them when developing special technical conditions, safety case for hazardous production facilities. The list of the main calculated risk indicators was formed back in the 1970s–1980s. For example, in the domestic and foreign practice, the following indicators of the risk of people death are used: potential risk (individual risk), collective risk (average rate of death), social risk (societal risk), individual risk (there is no foreign analogue). Overview of the approaches to the calculation of these indicators is given in the article, it is shown that they are generally accepted. A new approach to the calculation of risk indicators is proposed, which allows to consider the location of people and the time of their stay in more detail. Consider, in particular, dynamics of changes in the number of people at the facility, and in its vicinity during a given period, and the likelihood of people being in different places of the potential hazard zone at a particular point in time. These innovations make it possible to consider, for example, presence of the employees in different places during the working day, temporary gatherings of people during the day, for example, at the lunchtime in the canteen. Example of performing calculations according to the presented methodology is given. Consistency of the obtained results is shown. © 2022, STC Industrial Safety CJSC. All rights reserved.

Recording of the cavitation phenomena when modeling flows in the trunk pipelines
(2020) Sverchkov, A. M.; Sumskoy, S. I.; Сумской, Сергей Иванович
© 2020, STC Industrial Safety CJSC. All rights reserved.In the article, it is proposed to use a numerical method based on the approach of S.K. Godunov to simulate boiling in a pipeline. The paper presents a statement of the real problem of modeling a water hammer, considering possible boiling of the transpor-ted liquid on a real object — an oil pipeline. When solving the problem, two variants of flow modeling when closing the valve installed at the end of the pipeline were carried out. In the first case, the possibility of liquid boiling was not considered. In the second case, this opportunity was considered. The performed numerical simulation showed that in the pipeline in emergency situations, liquid columns can be formed, sepa-rated by the cavitation zones and oscillating in different phases, respectively, at the collapse of the cavitation zones, which serve as a kind of pressure dampers, the collisions of liquid columns occur, which can lead, depending on the ratio of velocities, to hydraulic shocks that occur not on the valves, but on the linear part of the pipeline (local hydraulic shocks). The waves from these collapses, interacting with each other, create the new pressure peaks that do not coincide with the pattern of simple wave circulation, which are predicted in the simulations that do not consider possible liquid boiling. As a result, the pressures reached in the pipeline during fluid hammer is significantly different from what it would be in the absence of boiling. When boiling is considered, the maximum reached pressures are 40 % higher. Moreover, this excess is repe-ated. The detailed analysis of the pressure profile in the pipeline is given in the article. Based on the results of solving this prob-lem, it is concluded that when modeling pre–emergency and emergency situations in the pipeline, it is necessary to consider the process of possible liquid boiling, since sometimes, as in the presented case, the values of the pressure surges can be higher than the values of the pressure surges in the liquid without considering boiling, which increases the likelihood of emergency depressurization.
