Customer Success Story Bently Nevada* Asset Condition Monitoring

  1. 1. GE Energy Oil & Gas – Petrochemical ProductionCustomer Success Story Bently Nevada* Asset Condition MonitoringCondition Monitoring Proves EssentialDuring Plant CommissioningBently Nevada 3500 machinery protection systems and GE’s System 1*Condition Monitoring and Diagnostics Software demonstrate their value,helping a plant to address root cause and avoid further costly damagerather than blindly replace damaged equipment.ProblemDuring the commissioning phase of a large petrochemical complex in the UK, routine overnighttesting of several process loops was conducted. The following morning two electric motor-drivenpumps were found completely wrecked.SolutionThe plant employs continuous online monitoring for its critical assets via four Bently Nevada 3500Series machinery protection systems linked to System 1 software. System 1* SoftwarePaybackData captured by System 1 software during the overnight testing indicated the machines had runat 7000 RPM in the reverse direction. The customer concluded that fluid must have run backwardsthrough the pumps, causing this reverse rotation, and immediately suspected the check valves asthe probable cause. When the check valves were inspected, the customer found the housings wereempty. Without this essential information, both pumps would have been replaced with spares fromstock, without addressing the root cause. A second set of pumps would have been wrecked at anestimated cost of 40,000 Euros.Benefits 3500 Series• C aptures vital information that may otherwise be missed unless continuous on-line Monitoring Systems monitoring is used. The subsequent delay or inability to determine root cause often results in further machine damage when equipment is returned to service prematurely.• R educes maintenance and operating expenses by providing data on actual machine condition, helping maintenance teams fix problems before serious and costly damage occurs.• P rovides advanced information to help maintenance teams anticipate what and where the problems are prior to opening the machine, minimizing costly downtime.
