Effective Machinery Fault Diagnosis Avoids Unnecessary Gearbox Maintenance (Case Study)
Prevention of catastrophic failures.
Avoiding expensive unnecessary shutdowns and repairs.
Allowing minimum equipment downtime.
During the commissioning of a gas turbine driven crude oil loading pump, the load gearbox has experienced excessive vibration which limited the pumpset capability and raised concern over the mechanical integrity of the gearbox and the reliability of a critical equipment. The causes for the problem were traced to improper vibration sensor’s holder design and istallation.
This case study highlights the experienced problem, and the efforts involved in its analysis and identification. It also reviews the corrective actions taken to effectively resolve it with minimum effort, downtime and cost.
