Initial Problem Over-pressured inter-stage piping caused by an Engine Emergency Shutdown
(ESD) allowing field discharge pressure to short-circuit through unit piping and expand rapidly into a small volume inter-stage header.
Solution Install check valves on Unit 3 and 4 Discharge piping and
a Relief Valve on the Common Inter-stage Piping
GC-00466: NVL Discharge Check Valves
