DEVELOPMENT OF AN INFORMATION AND ANALYTICAL SYSTEM FOR FORECASTING THE REMAINING LIFE OF FIELD PIPELINES UNDER SEVERE CLIMATIC CONDITIONS

This article examines an approach to developing an information and analytical system for predicting the remaining service life of industrial pipelines operating in low-temperature conditions, with seasonal soil variability and increased heterogeneity of degradation processes. It is demonstrated that isolated calculations based on minimum wall thickness are insufficient for reliable prediction. A unified data structure, linking diagnostic results with operating modes, and consideration of climatic factors influencing both the corrosion rate and the stress-strain state of the pipe are required. A modular system architecture is proposed, input data requirements are defined, and a calculation core for resource assessment with scenario support and uncertainty management is described. The inclusion of a climatic and geotechnical contour is justified, allowing for the adjustment of survey and repair priorities in areas with heaving soils and in areas of seasonal freezing. An example of the logic for ranking sections based on a set of criteria is provided, and it is demonstrated how consideration of external influences can alter conclusions for equally deteriorated segments.
