• Faulty bearing vibration sensor detected at an upstream oil and gas facility

What did GE's analytics software find?

In July, GE's SmartSignal solution detected an erratic radial bearing vibration on a centrifugal compressor at an upstream oil and gas facility. GE’s Industrial Performance and Reliability Center (IPRC) notified the GE Rotating Equipment Engineer during the weekly conference call.

 

What was the underlying cause?

After reviewing the data extensively, the GE team concluded that the erratic readings were not valid, but rather a sign of faulty instrumentation. However, it was identified that the machine would shutdown if this single sensor reading reached the programmed shutdown limit. This information was provided to the customer, along with the recommendation that this sensor be put into bypass mode.

 

What was the value to the customer?

Due to the early notification, the customer was able to check and ensure the integrity of the machine protection system and set the control system to ignore the faulty readings, all while avoiding unplanned production loss.
