Topic - Electrostatic Discharge

Abstract - The Ethylene Unit turbomachinery team, together with their corporate
Engineering Team and GE’s Bently Nevada™ resources, successfully diagnosed and
mitigated a critical bearing failure mode on a 36,000 HP steam turbine. Following a
process upset, the steam turbine was diagnosed with a possible light rub. As vibration
levels continued to rise over the ensuing weeks it was noted that there were indications
of typical electrostatic discharge. Using System 1®, GE Bently Nevada’s flagship
condition monitoring program, the team was able to diagnose this rub and additionally
diagnose the electrical discharge phenomenon that was destroying one of the critical
steam turbine’s journal bearings at an alarming rate of 1%/day. The team employed
grounding brush technology to stop the progression of this bearing failure mode.
Because of the team’s prompt reaction and troubleshooting skills using the System 1
tools, the failure mode was impeded before it would have necessitated an immediate
unit outage to make bearing repairs. This allowed the Ethylene Unit to continue to
operate and avoid a 14 day outage. The outage would have cost $3.2MM ($200M L&M,
$524M Startup & Shutdown, and $2.46MM lost earnings).
