Condition Monitoring Tech.- Reliability
Newmont North America
08.2024 - Current
- Manage condition monitoring and predictive maintenance program.
- Vibration Analysis: Monitor and analyze vibration data from rotating machinery to detect imbalances, misalignments, and bearing faults.
- Thermography: Use infrared thermography to detect high temperature in SAG and Ball Pinion and Girth gears, bearings and other rotating equipment
- Oil Analysis: Perform lubricant and oil analysis to identify contamination, wear particles, and degradation of lubricants.
- Ultrasound Testing: Use ultrasound technology to detect cracks, electrical discharge, and mechanical wear in equipment.
- Compare current condition monitoring data with historical data to identify trends and predict potential failures.
- Root Cause Analysis: Conduct in-depth analysis to determine the root causes of detected anomalies or failures, using techniques such as Fault Tree Analysis (FTA) or Failure Modes and Effects Analysis (FMEA).
- Track and monitor the condition of critical assets over time to identify patterns that indicate wear or impending failure.
- Prepare detailed reports on the health status of machinery and equipment, including recommendations for maintenance actions.
- Raise notifications to maintenance teams when equipment conditions reach critical thresholds that require immediate attention.
- Communicate findings and recommendations to maintenance teams, engineers, and management to ensure timely and effective decision-making.
