  1. Overall Goal of a System Engineer?
    To improve the reliability, efficiency, and overall performance of our systems
  2. What are objectives of systems engineering? How do they accmploish goal?
    • Prevent failures from occuring
    • Develop a system monitoring plan
    • 1. Define Functions
    • 2. Define Failure Modes
    • 3. Define Condition Indicators (what can be measured and analyzed to predict and prevent failures)
  3. Example of a Monitoring Plan
    • Heat Exchanger System
    • Function: Heat Removal
    • Failure Modes: Fouled Tubes, Motor Degredation or Failure, Pump Size, Shaft Sheer, Pipe Break, etc.
    • Condition Indicators: Bearing Temperature, Motor Current, D/P, oil analysis, vibrations, flow rate, etc.
  4. What is System IQ and how does it help engineers?
    • What: Tool to organize, gather, and analyze data.
    • Help Engineers:
    • 1. Collect Data
    • 2. Monitor/Trend Data (expectation of 4 hours per week)
    • 3. Document Actions
    • 4. Communicate
  5. Sources of System Monitoring
    • IPDADS – Integrated Performance Database and Analysis System
    •      Database from maintenance PM’s
    • CORA – Operations data from AO’s and CR logs
    •      Plant IQ – Condition Noification reports (CNR)
    •      Records results from PM’s (thermography, lube oil analysis, vibration analysis)
    • PI
    • FDT
    • Daily PVARS
    • Talking w/ Maintenance/Operations
    • Walk-downs
  6. Ways to monitor and trend
    • System IQ alarms
    • Manual Spreadsheets
    • Walkdowns
    • Manual Review of PI
    • CORA logs, etc.
  7. How we document actions
    • System narrative Log in System IQ
    • Action Plans (page 8 of Handbook)
    •     Red/Yellow System Recovery Plans
    •     Significant Issue Action Plans
    •     M-Rule Action Plans (a)(1)
  8. How we communicate
    • System Health Report: communicate general effectiveness of programs/process/systems in order to maintain system material condition and performance
    • GOAL: To focus the site's limited resources and attention to where they are needed the most
  9. Performance Areas of System Health Reports
    • 1. Operational Performance
    • 2. Material Condition
    • 3. M-Rule
    • 4. System Performance Monitoring
    • 5. Significant Issues
    • 6. Life-Cycle Management
  10. Example of Operational Performance
    • Unplanned LCO entry
    • Significant OD/FA
    • Operator Work Arounds
  11. Example of Material Condition
    • Walkdown results
    • Online Corrective Backlog
  12. Example of M-Rule
    • Reliability
    • Unavailability
  13. Example of System Performance Monitoring
    • Predictive Maintenance
    • Inservice Testing
    • System Health Trends and Critical Equipment Failures
  14. Example of Significant Issues
    Per handbook definition
  15. Example of Life-Cycle Management
    • Modificaitons
    • Single Point Vulnerabilities
    • Margin Management Issues
    • Long Range Planning
    • Obsolescence
  16. Differences between Component Health Reports and System Health Reports
    Not much difference, format is basically the same except system health includes M-Rule “Different way to slice the pie”
