Remote monitoring allows facilities to plan maintenance effectively before defects result in downtime.

Remote monitoring software helps industrial facilities know when a problem arises before it leads to system failure. With the large number of components in operation at oil and gas facilities, early warnings can prevent small problems from turning into big expenses.
Loose Bolt on a Lube Oil Cooler Motor
A software monitoring solution recently detected a gradual increase in cooler vibration on a lube oil cooler motor at an oil and gas facility. Given the speed and load on the machine, cooler vibration was expected to be around 0.15 inches per second (in/sec). However, actual values were reading up to 0.22 in/sec. The software provider notified the end user in a weekly report and began tracking the issue on weekly calls. After investigating the issue, the end user discovered a loose motor mounting bolt. The user subsequently tightened the bolt, and the vibration reading came back to model prediction (see Figure 1).
Defective Bearing on a Lube Oil Cooling Fan Motor
The software monitoring solution also detected a step change in the lube oil header temperature and thrust bearing temperatures on a compressor at another oil and gas facility. Given the speed and load on the machine, the lube oil header temperature was expected to remain at approximately 133 F (56 C). However, the actual temperature had increased to approximately 146 F (63 C). The software provider sent a high-priority email notification to the facility and began tracking the issue on the weekly calls.
