Description
In this unique and complex case study, we will dive into Equipment which was failed by broken IGV for 5 times and high vibration issues. Dominant frequency are sub synchronous vibration components (0.32X, 0.18X).
RCA by various parties unable to resolve the issues. MDS Engineer was called in but to no avail. Bad actor approach was taken i.e. review operating parameters, maintenance history and trip events. Also, looking at other operators that has similar problem and resolution. A site performance test and surge test were performed to understand dynamic behaviour. An engineering design change and material upgrade were made with assistance from OEM.
Learning Topics:
- Bad actor elimination
- Data collection
- Vibration analysis
