Narrative
Scada alarmed that the brackettville pump station gas detector alarm had gone off and activated an emergency shutdown at the station. Upon arrival, the techs discovered that the 3/8" tubing, connected to pit-312, sheared off. The pit was isolated and the fitting was replaced. The 3/8" tubing sheared at the fitting above the ferrule and was sent to stress engineering for metallurgical review. Our current root cause analysis and metallurgical review indicates we have elevated vibration at brackettville pump station produced by pump vane pass frequency and motor critical frequency aligned. Our next step in verification of vibration requires that we get a second opinion outside of the initial post component failure vibration report. This will be performed on august 19, 2019 and expect the final report analysis approximately 2 weeks after that. O with the extended services (motion amplification & physical sensor placement) our goal is to rule out any other possibilities I.E. Piping design, motor alone, etc. O test results will visually indicate elevated vibration points and provide a basis for temporary for permanent structural support. O the combined data will help provide justification for pump overhaul to mitigate vane pass frequency. O this visual indicator will assist in pin-pointing exact bracing locations for instrumentation piping support and include all station piping.
