Identification of the underlying problem
Whenever a component or product fails in service or if failure occurs in manufacturing or during production processing, failure analysis plays a very important role. In any case, one must determine the cause of failure to prevent future occurrence, and/or to improve the performance of the device, component or structure.
Typical examples of systems/equipment that can be analyzed are electrical generators, heat exchangers, valves, control systems, pumps, components of gas turbines and compressors.
Failure Analysis will disclose;
• Why the event, failure or breakdown occurred
• How future failures can be controlled or eliminated
Analysis to Identify the Causes of Failure / Breakdown
Failure analyses of the repairable systems focus on the model capability to identify, control and eliminate future failures, for a system.
• Root Cause Analysis
• Pareto Analysis for Downtime
• MTBF-MTTR Trending for Bad Assets
• Effect of MTTR on Asset Availability
• Breakdown Analysis
• Identification of Dominant Failure Codes
• Effect of Unplanned Cost on Maintenance Cost
• Analyze Reactive Maintenance
Benefits
• Uses advanced investigative techniques
• Identifies early (unlikely) life failures
• Extends equipment lifetime
• Reduced cost of maintenance
• Improves availability “up-time” and increased production
• Increases safety
• Easy to identify for potential losses where risk is included
