CST02 - Chandlersville and St. Paul: Unique Piping Vibration Issue in a New Centrifugal Compressor Installation
Abstract
An unexpected vibration issue was seen at two of Tallgrass Energys recently installed compressor stations (Chandlersville and St. Paul) and was associated with certain operating conditions when specific combinations of the three identical centrifugal compressors were in operation. Vibration issues occurring only at certain operating conditions for each identical unit would be typical, but the unique aspect of the problem at these stations was that only certain combinations of the compressors excited a system-wide acoustic response. The vortex-shedding resonance propagated into the entire piping system to create high amplitude pulsations in the lateral lines and headers. For the above-noted vibration issue, this paper will describe the problem, before field data, the methods used to analyze the problem, the resulting solutions that were implemented, and after field data.
