Failure Monitoring and Asset Condition Asssessment in Gas Supply Systems

Abstract

Abstract The urgent task is assessment of the emergency danger of damage to overhead and underground gas pipelines, depending on conditions of their laying, the nature of damage, gas pressures, diameters, atmospheric impact, as well as assessment of the environmental impacts of the gas leaks from damaged gas pipelines. Despite equipment and technologies improvement, the safety factor of the gas supply systems remains a priority. The purpose of this study to investigate issues of technological and functional reliability of the gas distribution systems. Development methodological principles for efficiency increase and reliability of the gas distribution systems by narrowing zone of economic uncertainty and establishment communication between reliability indicators and design features of the gas supply systems. Methods of the system analysis are used. The research is based on generalization and systematization of materials of the gas distribution organizations for gasification the territory of the Russian Federation. There is the analysis of statistical data on accident rate at the objects of the gas industry during the period from 2010 to 2016. Calculation of the number and specifics of the accidents occurrence is carried out on the basis of a system analysis of the gas supply systems elements.
