Diagnostics of Loaded Foundations of Gas Compressor Station Without Process Shutdown

This paper presents the research results on the technical state of bearing structures of the frame and foundations of technological units of gas compressor station. Visual and instrumental inspection and vibration tests of foundations were performed to estimate the technical state of bearing structures. The results indicate to defects and damages in foundations which have a negative impact on their performance. Crack openings 0,1 mm width are detected in foundations; the strength of concrete foundation is below the designed. Amplitude-frequency characteristics obtained during the vibration tests indicate to the excessive horizontal displacements of foundations with respect to the limit values regulated by normative documents.
