Gazprom held the 10th International Scientific and Technical Conference "Gas Transportation Systems: Present and Future" (GTS-2025) for the first time in St. Petersburg at Gazprom VNIIGAZ. The conference was attended by over three hundred representatives of PJSC Gazprom and its subsidiaries, leading companies in the oil and gas sector, research institutes, centers and universities of the Russian Federation, as well as suppliers of products and services, industrial groups working in the field of gas transportation. The venues were Gazprom's flagship universities: the Empress Catherine II St. Petersburg Mining University and Peter the Great St. Petersburg Polytechnic University.
The conference program included a plenary session, technical sections and round tables, an exhibition “Gas Transport Systems: Present and Future,” and technical excursions.
The second and third days of the conference were held at the Polytechnic University. Scientists and engineers from SPbPU took part in the work of technical sections and round tables, where promising developments and technologies for gas transportation facilities were discussed.
Thus, at the section "Pipe Products and New Materials for PAO Gazprom Facilities", Director of the Scientific and Technical Complex "New Technologies and Materials" Alexey Alkhimenko presented a report on the research of the metal of steel pipes for transporting hydrogen-containing gas. He covered the methods of transporting hydrogen, the prospects for the development of the global hydrogen fuel market, the problems and mechanisms of hydrogen impact on materials and their compatibility. The speaker presented various testing methods that are carried out at the Polytechnic University.
The tasks of the Polytechnic University were to create an experimental base that would allow us to study the effect of hydrogen on materials, as well as to develop methods for this and a knowledge base that could then serve as the basis for creating domestic regulatory documentation. Accordingly, with VNIIGAZ and with the participation of companies that are our partners, we have created and are developing a laboratory complex, – said Alexey Alkhimenko.
Leading researcher of the Scientific and Technical Complex "New Technologies and Materials" Ivan Golubev took part in the work of the section "Design and Construction of GTS". He gave a report "Predictive Analytics of the Corrosion State of Field Pipelines for Transporting Untreated Gas".
Ivan Andreevich presented the research of the team of the Scientific and Technical Complex "New Technologies and Materials", which developed its own system of mathematical models for predicting the development of corrosion-erosion wear based on laboratory tests conducted at the Polytechnic University. The project was implemented as part of the R&D for PJSC Gazprom and includes the development of a software product that allows issuing recommendations on the selection of methods for ensuring the reliability of field pipelines. In the future, it is planned to develop the topic using both the experience gained during the implementation of the project and the accumulated over the years of research into the behavior of the material under specified operating conditions.
The combined use of mathematical modeling, experimental data and ML algorithms makes it possible to identify local areas with intense corrosion, predict the development of defects depending on changes in transportation modes, optimize the diagnostics and repair strategy, reducing operational risks, noted Ivan Golubev.
The program of the section "Operation, reconstruction and new technologies for GTS facilities" included reports by Professor of the Institute of Energy Alexander Drozdov "Experience of development and application of virtual simulators with PJSC Gazprom", engineers of the Higher School of Power Engineering Anton Pulin "Prospects for optimization of the gas transportation process due to complex digital twins of the gas transportation system and compressor stations" and Kirill Alisov "Application of modern additive technologies in the modernization of the internal cooling system of turbine blades".
At the section "Power Systems of PJSC Gazprom", representatives of the Higher School of Power Engineering covered the following topics: "Development of a Low-Capacity Microturbo-Expander Unit" (engineer Anton Balakin), "Criterial Optimization Using Regression Analysis" (assistant Mikhail Laptev), "Application of Modern Additive Technologies for Unscheduled Repairs of Gas Turbine Elements" (engineer Ivan Talabira), and "Development of an Automated Complex for Designing and Optimizing Radial-Axial Turbines" (engineer Ivan Nurkov).
