About this document

Steam Turbine Vibration Diagnosis Report by MANOJ KUMAR is a document available to read on EtoBox.

The steam turbine driving a hydrogen compressor experienced intermittent high vibration spikes. Vibration analysis determined the cause was intermittent rubbing of the rotor. After a trip, inspection found carbonized oil in the bearing housing from lack of sealing air. The oil baffles were cleaned and sealing air recommissioned. No significant vibration spikes occurred after restart, showing the mitigations were effective.
