Study Notes
Importance of Regular Readings
- Automatic equipment can be ignored, leading to complacency and adverse conditions
- Regular readings can help avoid adverse conditions and encourage operators to:
- Familiarize themselves with equipment
- Assess operating conditions
- Diagnose problems
- Identify operating trends
Taking Readings
- Readings are taken from field instruments, chart recorders, or computer screens
- Readings are necessary to compare current field conditions with expected performance
- Immediate action can be taken if a reading is outside the expected range
- Examples of readings include lubrication oil temperature and bearing vibrations
Field Operators
- Field operators take readings while performing rounds
- Readings are recorded on a sheet and can be stored for historical data
- Historical data can help explain recurring problems
Control Room Operators
- Control room operators must also take readings to:
- Assess system performance
- Foresee problems
- Take action
- Chart recorders and electronic displays are used to assist control room operators
- Electronic displays can show thousands of control parameters simultaneously
Chart Recorders
- Mechanical chart recorders require paper and ink, which need to be replaced periodically
- Circular chart recorders are renewed daily or weekly, depending on the recorder mechanism
- Recorded trends can be dedicated to specific equipment or processes
