General provisions

108. Hazard analysis of technological processes, quantitative risk analysis and other methods for analyzing the risk of accidents associated with the release of transported hydrocarbons are part of the industrial safety declaration, safety justification, risk management and industrial safety management system of the HPF MT.

109. When conducting a risk analysis, the following is taken into account:

explosion hazard and toxic properties of the transported product;

external anthropogenic influences (including from neighboring objects, intersections with transport routes, possible unauthorized taps into the pipeline and sabotage);

possible manifestations of internal and external corrosion;

possible deviations of technological parameters from regulatory values;

indicators of mechanical safety (resistance to loads and impacts), reliability of the MT hazardous production facility and technical devices used at the MT hazardous production facility (strength characteristics of the material, pipe wall thickness, manufacturing technology, transportation and storage conditions during construction);

design and technological safety measures (protection against excess pressure, including water hammer, measures to prevent hydrate formation on gas pipelines, the effectiveness of leak detection systems and telemechanics, the possibility of loss of stability of the pipeline position, fire barriers);

external natural influences (earthquakes, landslides, ground conditions, icing, other hydrometeorological, seismic and geological hazards);

the impact of possible environmental consequences during construction, operation, reconstruction, technical re-equipment, major repairs, conservation and liquidation of hazardous production facilities, including environmental pollution, disturbance of the fertile soil layer, vegetation cover, landscape;

damaging factors of accidents (release of hazardous substances, destruction of technical devices, structures, explosion, thermal, toxic damage, scattering of fragments, environmental pollution), as well as the possibility of disruption of the fertile soil layer and vegetation during localization of accidents and liquidation of their consequences;

the impact of the consequences of accidents and incidents at hazardous production facilities on neighboring production facilities, settlements, water intakes, nature reserves and other environmentally vulnerable objects.

110. Methods for risk analysis at hazardous production facilities must be justified in accordance with the requirements of the legislation of the Russian Federation in the field of industrial safety.

111. The danger of operating a hazardous production facility is determined by a complex of factors that take into account the technological parameters and technical condition of the hazardous production facility, the properties of the pumped hazardous substances, natural and anthropogenic factors.

112. The main purpose of risk analysis is to provide officials decision-makers to ensure safety, information about the most dangerous processes, areas of hazardous industrial production facilities.

113.

114. In order to justify accident prevention measures, an analysis of the hazards of technological processes should be carried out with the determination of deviations of technological parameters from the design (regulatory) values ​​with a description possible reasons, the consequences of these deviations and an indication of the security measures taken or planned. The analysis is carried out by a group of specialists from design and operating organizations with the participation of an independent expert organization. The result of the group’s work is a report describing possible causes, consequences of these deviations, indicating safety measures and recommendations for further actions or improving safety.

Principles of quantitative analysis of the risk of accidents at hazardous production facilities of main pipelines

115. The process of conducting a quantitative accident risk analysis includes the following main four steps:

1) planning and organization of work;

2) identification of accident hazards;

3) quantitative assessment of the risk of accidents at industrial hazardous production facilities, including:

a) assessment of the frequency of possible accident scenarios;

b) assessment of possible consequences for the considered accident scenarios;

c) calculation of accident risk indicators at industrial hazardous production facilities;

d) determination of the degree of danger of sites and components of hazardous production facilities;

e) ranking of sections and components of transport hazardous production facilities according to accident risk indicators;

f) comparison of accident risk indicators of sections and components of hazardous industrial facilities of transport infrastructure with the corresponding average statistical level and establishment of the degree of danger of sections and components of transport infrastructure;

116. When analyzing the results of calculations at the sites and components of hazardous production facilities, MT compare the calculated risk indicators with the average statistical level of accident risk according to the following degrees:

extremely high.

For sections of the linear part of the HPF MT, the degree of accident danger is determined based on the difference between the value of the accident risk indicator calculated for the section and the average statistical level of accident risk. The average statistical level of the accident risk indicator is determined based on data on the investigation of accidents at similar facilities.

Under the calculated accident risk indicator R understand one or more indicators:

frequency of accidents per unit length of a linear part of a hazardous industrial facility or in a specific area (for example, an underwater crossing), leading to death of at least N Human ( N = 1, 10, 50);

individual risk of death or injury to a person in an accident on the linear part of a hazardous production facility;

frequency of accidents per unit length of a linear part of a hazardous industrial facility or in a specific area, leading to an oil/petroleum product spill weighing at least M (M= 100 t, 500 t, 5000 t).

Requirements for recording the results of an accident risk analysis on a main pipeline

117. The results of assessing the degree of risk of an accident at a hazardous production facility must be justified and formalized in such a way that the calculations and conclusions made can be checked and repeated by qualified specialists who did not participate in the initial procedure for assessing the risk of an accident at a hazardous production facility.

118. The process and results of work on the quantitative analysis of the risk of an accident at a hazardous industrial production facility are documented in the form of a report on the analysis of the risk of an accident at a hazardous production facility. The report on the analysis of the accident risk at the MT hazardous production facility includes:

119. The results of the analysis of the risk of an accident at a hazardous production facility MT when developing special documents (declaration of industrial safety, safety justification, plan for localization and elimination of accidents) are drawn up in accordance with the Guidelines for conducting risk analysis of hazardous production facilities, approved by the resolution of the Federal Mining and Industrial Supervision of Russia dated July 10, 2001 No. 30 (recognized as not requiring state registration - letter of the Ministry of Justice of the Russian Federation dated August 20, 2001 No. 07/8411-UD).

Determination of safe distances

120. Safe distance from HPF MT is determined by calculating the maximum zones of impact (damage) during emergency releases of hazardous substances, taking into account the likelihood of their implementation.

121. The calculation should be carried out on the basis of the following provisions:

1. The linear part of the HPF MT meets the safety requirements for reducing the severity of the consequences of accidents, including an automated leak detection system, an accident response system, and the presence of engineering structures to limit the spill of hazardous substances.

2. Determine the most dangerous scenarios in which the maximum size of the impact zone (damage) is possible.

3. Calculation of the process of release, dispersion and drift of a cloud of hazardous substances in the atmosphere is carried out under various weather conditions and taking into account the terrain.

4. When justifying minimum distances use quantitative criteria that take into account the maximum size of the impact zone (damage) and the values ​​of calculated risk indicators. Safety criteria or permissible (acceptable) risk are justified in the design documentation/documentation.

a) assessment of the frequency of possible accident scenarios;

b) assessment of possible consequences for the considered accident scenarios;

c) calculation of accident risk indicators at industrial hazardous production facilities;

d) determination of the degree of danger of sites and components of hazardous production facilities;

e) ranking of sections and components of transport hazardous production facilities according to accident risk indicators;

f) comparison of accident risk indicators of sections and components of hazardous industrial facilities of transport infrastructure with the corresponding average statistical level and establishment of the degree of danger of sections and components of transport infrastructure;

116. When analyzing the results of calculations at the sites and components of hazardous production facilities, MT compare the calculated risk indicators with the average statistical level of accident risk according to the following degrees:

low;

For sections of the linear part of the HPF MT, the degree of accident danger is determined based on the difference between the value of the accident risk indicator calculated for the section and the average statistical level of accident risk. The average statistical level of the accident risk indicator is determined based on data on the investigation of accidents at similar facilities.

Under the calculated accident risk indicator R understand one or more indicators:

frequency of accidents per unit length of a linear part of a hazardous industrial facility or in a specific area (for example, an underwater crossing), leading to the death of at least N people (N = 1, 10, 50);

individual risk of death or injury to a person in an accident on the linear part of a hazardous production facility;

frequency of accidents per unit length of a linear part of a hazardous industrial facility or in a specific area, leading to an oil/petroleum product spill weighing at least M (M = 100 t, 500 t, 5000 t).

Requirements for recording the results of an accident risk analysis on a main pipeline

119. The results of the analysis of the risk of an accident at a hazardous production facility MT when developing special documents (declaration of industrial safety, safety justification, plan for localization and elimination of accidents) are drawn up in accordance with Methodical instructions to conduct a risk analysis of hazardous production facilities, approved by Decree of the Federal Mining and Industrial Supervision of Russia dated July 10, 2001 N 30 (recognized as not requiring state registration- letter of the Ministry of Justice of the Russian Federation dated August 20, 2001 N 07/8411-UD).

Determination of safe distances

120. The safe distance from hazardous production facilities is determined by calculating the maximum impact zones (damage) during emergency releases of hazardous substances, taking into account the likelihood of their implementation.

121. The calculation should be carried out on the basis of the following provisions:

1. The linear part of the HPF MT meets the safety requirements for reducing the severity of the consequences of accidents, including an automated leak detection system, an accident response system, and the presence of engineering structures to limit the spill of hazardous substances.

2. Determine the most dangerous scenarios in which the maximum size of the impact zone (damage) is possible.

3. Calculation of the process of release, dispersion and drift of a cloud of hazardous substances in the atmosphere is carried out under various weather conditions and taking into account the terrain.

4. When justifying the minimum distances, quantitative criteria are used that take into account the maximum size of the impact zone (damage) and the values ​​of the calculated risk indicators. Safety criteria or permissible (acceptable) risk are justified in the design documentation/documentation.
