This study aims to develop an analytical method for accurately identifying leak locations in gas pipelines based on unsteady gas flow dynamics. A novel approach is proposed that utilizes pressure variations at the inlet and outlet points to determine the minimum fixation time (t = t1) required for real-time leak detection. Through mathematical modeling and numerical analysis, the study demonstrates that the ratio of pressure drops at different points along the pipeline can be effectively used to pinpoint leakage locations. The results indicate that the proposed method significantly improves detection accuracy and response time, making it a viable solution for integration into gas pipeline monitoring and control systems.

Analysis of global trends, issues in the development of the gas industry, and possible levels of ... more Analysis of global trends, issues in the development of the gas industry, and possible levels of gas consumption in various countries indicates that natural gas is increasingly taking on a more significant role compared to other fuel types in the developed countries of the world. However, with the increase in consumers adapted to using gas, there is a need for a substantial increase in natural gas reserves, expansion of networks, and regulatory complexes. Growing gas demand and resource consumption can be met not only through the construction of new networks and structures but also through the reconstruction of gas pipelines using potential reserves and efficient management. Ensuring the reliable operation of existing gas supply systems requires ongoing operational and capital expenditures, meaning that the continuous updating of morally and physically outdated equipment and networks is necessary. The gas supply system, as an energy transmission system, continues to develop successfully compared to other fuel types. Along with the development of the resource base, the management system related to the reliable operation of the fuel and energy complex is also continually evolving. This reliability is primarily ensured through high-tech safety measures, considering the current trends in the globalization of the energy sector. However, this process is accompanied by reconstruction in existing gas pipelines. Currently, the reconstruction of main gas pipelines is a priority area for the innovative development of the management system, taking into account the use of advanced technologies and the operational principles of the fuel and energy complex. This also facilitates the prompt resolution of automation issues. An important feature of the monograph is the extensive analysis and examination of the parameters of non-stationary gas flow in complex gas pipelines, with a key characteristic being the in-depth study of the problem. Specifically, obtaining mathematical expressions for nonstationary gas flow allows for targeted control of gasodynamic processes. To this end, effective solutions for the reconstruction of gas transport systems have been investigated based on an information database about pipeline failure conditions, which was derived from changes in the technological parameters of gas flow in the peripheral sections of pipelines during emergency modes. Simultaneously, the resolution of dynamic issues in complex main gas pipelines has led to the discovery of previously unknown relationships and regularities, a more comprehensive analysis of problems, and the provision of well-founded conclusions and recommendations. Based on the results of theoretical studies, a calculation scheme has been developed that enables the creation of normative-technical documents for justifying organizational and technological decisions in the operation of main gas pipelines. Ensuring a high level of guaranteed gas supply to consumers is typically achieved through the reserve capacity of the pipeline system. Therefore, in the reconstruction of main gas pipeline systems, networks are generally proposed as parallel multi-line configurations. In the event of an emergency, due to the operational management of pipeline sections, there is no significant interruption in gas supply at the output (end) of the multi-line system, and consumers receive a continuous gas supply. During the justification stage of the reconstruction of main gas pipelines, to achieve the required levels of reliability and productivity, pipelines are usually arranged in multi-line configurations (a minimum of two lines) that are interconnected. Proposals have been made for the theoretical and technical foundations of operating parallel gas pipelines to ensure the efficient placement of distances between these connecting pipelines. The high-level operational reliability and efficiency of the reconstructed gas transmission scheme are achieved under several specific conditions:

The study extensively explores the dynamic behavior of processes for the supply of modern automatic devices for gas pipelines and the use of an efficient automated control system. The analytical determination of the optimal time for transition processes has been widely applied to ensure the high reliability of pipeline transportation and the most favorable operating conditions for the system. Methods for calculating complex transient processes in main gas pipelines, from non-stationary to stationary modes, have been utilized when gas ingress occurs in a non-stationary regime.

One of the solutions to the problem of improving the reliability of gas pipelines is the use of new effective scientifically based technologies for the reconstruction of pipeline systems. Obviously, connecting fittings, Looping's and connectors are one of the components of increasing the reliability of gas networks. To this end, a theoretically sound reporting scheme was developed for the design of gas networks, as well as for the development of new technological foundations of the gas pipeline network during its reconstruction and the prevention of possible gas losses due to modern equipment installed on these networks. This article explores the analytical expression for determining the economic length of interconnections between parallel gas pipelines and outlines a reconstruction variant for the effective methods of reconstructing multi-lines parallel gas pipelines.

Additionally, the conformity of the law governing the variation of pressure along the length of the pipeline over time under various operating conditions in a parallel pipeline system has been determined. Furthermore, recommendations for boundary conditions ensuring continuous operation in the pipeline section are proposed in relation to the occurrence of accidents in the gas pipeline.
The efficient operation regime of the pipeline system is determined to prevent the sudden cessation of gas supply to consumers through the theoretical investigation of the obtained analytical expressions of non-stationary gas dynamics. The purpose of the research is based on the premise that the strategy of reconstruction for managing non-stationary gas transportation processes with parallel pipeline systems relies on the characteristics of operating conditions to minimize the potential damage accidents could cause.

vibrations of a viscoelastic medium-contacting damaged
cylindrical shell under the action of external force
p = p0 + p1 sinω1t ( p0 is a medium or main force, p1 is
the amplitude of force change, 1
ω is the frequency of
change of the variable part of the force) and stiffened along
its generatrix with a rod whose material is inhomogeneous
and in circular direction with inhomogeous rings. The
structural element considered in the presented article
consists, according to the geometric structure, of a coating
and reinforcement elements, according to the mechanical
characteristics of heterogeneous coatings along the length,
having damage inside due to their physical structure and,
finally, a system in contact with a viscoelastic medium.
Taking into account one of the existing models (Winkler
or Pasternak), the contact conditions between the coating
and the reinforcement elements and the influence of the
medium on the coating, the frequency equation of
oscillation was solved, the results were analyzed. Theory
of hereditary type damage under the action of external
force is often used for taking into account the damages in
the structure of a cylindrical shell forced to vibration. The
Hamilton-Ostrogradsky variational principle is used for
solving the problem. The results obtained can be used in
the foundations of bridges built across mountain rivers.
Such support is cost-effective. It should be noted that
reinforcement and concrete mortar are also used in the
internal parts of the cylindrical supports used. The article
proposes to fill the inside of the cylindrical lid under study
with clay.

Additionally, a new calculation scheme has been employed to analyze the dynamics issues in complex main gas pipelines, identifying previously unknown relationships and legal requirements, allowing for a more comprehensive analysis of the problem and providing substantial findings and recommendations. Thus, mathematical expressions have been employed to analytically calculate complex transition processes in main pipeline chambers as a result of the simultaneous entry and exit processes of gas slugs from roadside pipes with varying dynamic parameters into the main pipeline chamber operating in a non-stationary regime. As a result, a cost-effective variant of the sequence of installation of outgoing and incoming pipelines has been identified to enhance the reliability of the pipeline operation.

That is, it is important, not to make the work of consumer enterprises dependent on the operating mode of the distribution pipeline supplying them with gas fuel, and to organize an uninterrupted gas supply to these consumers. For this purpose, it is important to develop new technological bases for the operation of the network and to develop a theoretically based computational scheme to prevent gas losses due to modern equipment installed in gas transport networks. One of the solutions to the problem of improving the reliability of gas pipelines is the use of effective scientifically based technologies. In the article, the efficient placement of connecting fittings to prevent gas losses in the operation of parallel gas pipelines was investigated, and proposals were made for theoretical and technical bases of the operation of parallel gas pipelines.

Additionally, the conformity of the law governing the variation of pressure along the length of the pipeline over time under various operating conditions in a parallel pipeline system has been determined. Furthermore, recommendations for boundary conditions ensuring continuous operation in the pipeline section are proposed in relation to the occurrence of accidents in the gas pipeline.
The efficient operation regime of the pipeline system is determined to prevent the sudden cessation of gas supply to consumers through the theoretical investigation of the obtained analytical expressions of non-stationary gas dynamics. The purpose of the research is based on the premise that the strategy of reconstruction for managing non-stationary gas transportation processes with parallel pipeline systems relies on the characteristics of operating conditions to minimize the potential damage accidents could cause.

vibrations of a viscoelastic medium-contacting damaged
cylindrical shell under the action of external force
p = p0 + p1 sinω1t ( p0 is a medium or main force, p1 is
the amplitude of force change, 1
ω is the frequency of
change of the variable part of the force) and stiffened along
its generatrix with a rod whose material is inhomogeneous
and in circular direction with inhomogeous rings. The
structural element considered in the presented article
consists, according to the geometric structure, of a coating
and reinforcement elements, according to the mechanical
characteristics of heterogeneous coatings along the length,
having damage inside due to their physical structure and,
finally, a system in contact with a viscoelastic medium.
Taking into account one of the existing models (Winkler
or Pasternak), the contact conditions between the coating
and the reinforcement elements and the influence of the
medium on the coating, the frequency equation of
oscillation was solved, the results were analyzed. Theory
of hereditary type damage under the action of external
force is often used for taking into account the damages in
the structure of a cylindrical shell forced to vibration. The
Hamilton-Ostrogradsky variational principle is used for
solving the problem. The results obtained can be used in
the foundations of bridges built across mountain rivers.
Such support is cost-effective. It should be noted that
reinforcement and concrete mortar are also used in the
internal parts of the cylindrical supports used. The article
proposes to fill the inside of the cylindrical lid under study
with clay.

processes in gas transportation based on the principles of the reconstruction phase. For complex gas pipeline systems, new approaches have been investigated for the modernization of existing control process monitoring systems. These approaches are based on modern achievements in control theory and information technology, aiming to select emergency and technological modes. One of the pressing issues is to develop a method to minimize the transmission time of measured and controlled data on
non-stationary flow parameters of gas networks to dispatcher control centers. Therefore, the reporting schemes obtained for creating a reliable information base for dispatcher centers using modern methods to efficiently manage the gas dynamic processes of non-stationary modes are of particular importanc

Additionally, a new calculation scheme has been employed to analyze the dynamics issues in complex main gas pipelines, identifying previously unknown relationships and legal requirements, allowing for a more comprehensive analysis of the problem and providing substantial findings and recommendations. Thus, mathematical expressions have been employed to analytically calculate complex transition processes in main pipeline chambers as a result of the simultaneous entry and exit processes of gas slugs from roadside pipes with varying dynamic parameters into the main pipeline chamber operating in a non-stationary regime. As a result, a cost-effective variant of the sequence of installation of outgoing and incoming pipelines has been identified to enhance the reliability of the pipeline operation.

That is, it is important, not to make the work of consumer enterprises dependent on the operating mode of the distribution pipeline supplying them with gas fuel, and to organize an uninterrupted gas supply to these consumers. For this purpose, it is important to develop new technological bases for the operation of the network and to develop a theoretically based computational scheme to prevent gas losses due to modern equipment installed in gas transport networks. One of the solutions to the problem of improving the reliability of gas pipelines is the use of effective scientifically based technologies. In the article, the efficient placement of connecting fittings to prevent gas losses in the operation of parallel gas pipelines was investigated, and proposals were made for theoretical and technical bases of the operation of parallel gas pipelines.
