The article discusses the prospects of improving the system of diagnostic maintenance of the equipment and pipelines of compressor stations of PJSC "Gazprom" The system, was introduced in the late 1990s–early 2000s in order to improve the reliability and safety of operation of gas transportation equipment. The introduction of this system has significantly reduced the number of accidents and incidents at compressor stations of main gas pipelines. At present, the gradual transition to the strategy of equipment operation "according to the technical condition" and risk-oriented approach to operation poses new challenges to the technical diagnostics system, which it did not solve previously, in particular – information support of decision-making within the framework of the operational system used.

The article outlines the main directions of improvement of the existing system used for diagnosing of compressor stations equipment and pipelines: harmonization of the technical diagnostics system with decision-making algorithms within the adopted system of equipment operation; development of high-performance means of technical diagnostics; improvement of the equipment industrial safety expertise; development of the algorithms for information-analytical processing of diagnostics results and formation of diagnostics data arrays, specialized information systems for their storage and processing; development and implementation of tools and methods for monitoring the technical state of the equipment.

The mandatory energy surveys have been conducted in PJSC "Gazprom" affiliated companies for more than 15 years, the results of which are used for development (correction) of the relevant energy saving programs.

The absence of separate items of costs for these programs’ implementation in PJSC "Gazprom" and its affiliated companies complicates the introduction of energy-saving measures, involving the replacement of the obsolete main and auxiliary technological equipment (including energy equipment) in a shorter time than the planned capital repairs of technological facilities or their modernization, reconstruction.

This paper considers the main problems of the mandatory energy surveys of PJSC "Gazprom" affiliated companies and proposals to their effectiveness enhancement. The possibility of using the mechanism of the energy service contract to improve the efficiency of energy saving measures is discussed.

Keywords: energy survey; energy saving measures; energy service contract.

Provision of reliable and efficient operation of gas pipelines is achieved by a variety of organizational-technical measures, a significant part of which is technical diagnosis, maintenance and repair of gas pipelines.

A significant part of the companies-operators of main gas pipelines in order to organize maintenance and repair uses complex models that combine both the implementation of planned works and maintenance of process equipment and pipelines.

When using such models, technical diagnostics should be a "reasonable investment", that is, the performance of these works should provide a reduction of costs spent on maintenance and repair of gas pipelines.

At the same time, main gas pipelines are complex technological complexes of hazardous production facilities, and their operation throughout the entire period of use should be carried out only in case of compliance with industrial safety requirements, that should also be accounted of when organizing their maintenance.

Thus, the main gas pipeline operators face the need to find modern technical solutions that provide achievement of maximum efficiency of technical diagnostics.

To solve this problem, the paper substantiates the expediency of the automated systems use to monitor the technical state of the main gas pipelines.

Keywords: main gas pipeline; technical diagnostics; non-destructive testing; automated monitoring; stress-strain state; limit state criterion; mechanics of destruction.

Combined sound proofing casings are used to increase the acoustic efficiency of sound insulation and to minimize the disadvantages of using different types of single-layer sound-proofing coatings. The results of the acoustic tests of the combined sound-proofing casing made of foam glass and rock-wool installed on the piping of the centrifugal compressor of the linear compressor station (CS) of PJSC "Gazprom" are considered.

The problems related to sound insulation of technological pipelines of centrifugal compressors in JSC "Gazprom orgenergogaz" have been studied for the past 10 years. At the same time, along with the environmental issues and compliance with the sanitary standards, the tasks of improving the operational reliability of the equipment and CS pipelines at the expense of the pipelines control serviceability are considered. During this time about 80 pipelines of CS centrifugal compressors and blocks of reducing lines of gas distribution stations (GDS) of PJSC "Gazprom", made of various materials of noise-insulating casings, such as bitumen mastic, rock-wool, foam glass, synthetic rubber, were examined. The results of field tests performed in 2008–2009 made it possible to conclude that the soundproofing casings based on single-layer foam-glass coatings have a very low acoustic efficiency. In addition, these coatings proved their short operational life-time, thus, after a short operational period (about 1 year), multiple through cracks were detected at the joints of foam glass segments gluing. The sound insulation of coatings based on bitumen mastic are ineffective and are currently prohibited for use under high flammability conditions. Mineral fiber-based coatings do not meet the requirements of the Internal Ruling Document (IRD) 39-1.8-055-2002 for the protection of pipelines against corrosion due to high water absorption values and vapor permeability. Judging by the Technical Conditions, in the tested product, the combination of layers of foam glass and rock-wool should provide high sound insulation and exclude the conditions for the occurrence of a pipe surface corrosion under the insulation.

The article analyzes the results of noise measurements and visual-instrumental monitoring of the technical condition of the soundproofing casing and the pipeline surface at the points of the insulation opening. Based on the results of noise measurements, the sound insulation of both the casing assembly and its individual layers was estimated.

In conditions of gradual aging of fixed assets of gas production facilities, the role of diagnostic maintenance increases as an important element of the system to ensure the reliability and safety of operation. The principles and methods of diagnostic maintenance of gas field facilities are somewhat different from similar algorithms used for other facilities due to the uniqueness of each gas field as a technical facility. In the previous period, the specialists of JSC "Gazprom orgenergogaz" under the leadership of PJSC "Gazprom" developed the basic operational principles of the diagnostic maintenance system of gas production facilities, which proved their efficiency. Further directions of the developed system updating are revision of normative documentation with account of diagnostic examination experience generalization of various types of gas-field equipment and need of introduction of new forms of repair and maintenance organization, development of new effective methods and means of technical diagnostics as well as algorithms of analytical processing of diagnostics data, introduction of effective information systems that provide assessment of technical condition and storage of diagnostics results.

Due to the fact, that a significant part of the heat supply facilities of PJSC "Gazprom" has been in operation for 25 years or more, it becomes urgent to improve and periodically to analyze their technical state and efficiency. The paper considers the possibility of regime-adjustment testing to maintain high reliability and achieve maximum efficiency of the heat supply system. Organization of regime-adjustment testing requires use of capabilities certified automated information-analytical systems, that provide formation of a database with the characteristics of the heating system elements, control of the key designed thermal and hydraulic parameters in the heat source, heat networks and in consumers inputs and promptly obtain information about the estimated consequences of operative (operational) personnel actions in the heat supply system. This system in a clear and accessible form will display information about the current operating modes of boiler units, heat networks and heat consumption systems as well as allows to simulate the operating conditions of the heat supply system with the emergence of new loads. Thus, the complex of regime-adjustment tests and the introduction of electronic models will not only improve but also increase the heat supply efficiency.
