Evaluation of the Influence of Icing on the Functioning of Main Pipeline by Means of Fuzzy Logic Methods

Abstract

The main pipelines passing through the distribution area of the permafrost zone are affected by various negative processes, such as, for example, thermokarst, swelling, erosion, solifluction, etc., including ice formation. The purpose of this article is to study the effect of icing formation on the performance of trunk pipelines using the Power of Siberia trunk gas pipeline as an example. Icing is a layered ice mass formed when periodically spilling underground or surface water freezes. They are a particularly dangerous glacial phenomenon, the negative impact of which is determined by: a) unexpected flooding of the territory in the cold season; b) crystallization of water and the appearance of static and thermodynamic pressure of ice; c) the formation of ice barriers and increased slippery roads, sidewalks, ground coverings; d) the development of associated hazardous processes - cryogenic heaving, frost cracking, thermoerosion, the formation of injection ice, uneven precipitation of the day surface, etc. The influence of ice has a negative impact on the performance of main pipeline systems, causes the need for increased requirements for materials, structures, and laying technologies, and negatively affects the environmental situation of the region in the event of emergencies. In this paper, based on the application of fuzzy logic methods, the main factors affecting the process of icing are identified, the degree of influence of ice on the performance of the main pipeline is estimated, the rules of fuzzy inference are developed to minimize the effect of ice formation and identify hazardous areas for preventive measures to reduce risk emergencies This electronic document is a “live” template and already defines the components of your paper [title, text, heads, etc.] in its style sheet.
