Sub-synchronous vibration “SSV” troubleshooting is challenge especially during mechanical run test of API 617 centrifugal compressor. This presentation discusses the possible causes of the SSV in addition to share the troubleshooting and finding of new multistage API 617 compressor experienced SSV at the factory acceptance test. The presented case shows the influence of the axial float and the thrust bearing lubrication on the SSV appearance. Moreover, the effect of the testing averment such as vacuumed test on the sub-synchronous. The effect of the sub-synchronous vibration on the long and short terms and the path forward in case of sub-synchronous.
Conduct factory acceptance test for gas compressors as per API-617
