The physical modeling resultsdemonstrate the ability to diagnose instability of above-groundpipelinesupports using acoustic noiserecorded on the pipe surface. It is shown that developed in recent years method of extraction coherent components of noise field allows to determine frequencies and geometric shapes of flexural standing waves in pipelines. This information can be used to estimate the stabilityof pipeline supports. Supportinstabilityincreasing the span between rigid pipeattachments manifests itself in a dramatic restructuring of thestanding waves field formed in the pipe by acoustic noise.
Keywords: pipelines, supports instability, noise field, standing waves, physical modelling.
