The conclusions of the Conference:

Trunk pipeline transport continues to be a key element of the global energy sector, the reliable operation of which depends on the energy stability and safety of the economies of Russia, European and Asian countries.

The GTS system of Russia and its new main gas pipelines (Bovanenkovo-Ukhta, North-European Gas Pipeline, Power of Siberia) have no world analogs, integrate the advanced technical and technological achievements on production capacity and efficiency for operation under harsh natural climatic conditions.

The optimal development of pipeline transport depends significantly on research-based policy, integrated development of projects for construction and reconstruction of GTS facilities covering all stages of the life cycle, and the introduction of innovative technical solutions, materials, equipment and technologies. The system complex approach based on methodical, theoretical and experimental researches provides the required quality of facilities design and construction, highly reliable and safety GTS operation on long terms of service.

The system approach in cooperation between the managing companies, operating gas transport companies, designers, builders and manufacturers-suppliers of the equipment and services with the scientific centers, including in the area of technical regulation, development, tests and production certification, increases efficiency of using of innovative pipe production, gas pumping equipment, compressor station junction points and systems, etc.
