Study Notes

Plant Maintenance Management

Managing maintenance in a plant can be complex, especially in larger plants with many components.
Preventative Maintenance (PM) systems schedule regular maintenance to predict equipment problems before they cause outages.

Preventative Maintenance (PM) Systems

PM systems cover all plant equipment, with each item having specific required checks.
Regular inspections determine equipment health.
Typical PM activities include:
- Review of recorded operating parameters
- Vibration monitoring
- Equipment inspection
- Lubricating oil sampling and testing
- Equipment adjustment
- Bump tests
- Shaft rotation
- Instrument calibration
- Parts replacement
- Equipment duty swap
- Safety valve testing and calibration
- Operation of standby equipment (such as generators and fire pumps)

Preventative Maintenance Tasks

Oil Level Checks:
- Checking oil level is a regular activity. +Understanding how to ensure correct oil levels is important.
- Characteristics to consider include viscosity, viscosity index, flash point, pour point, and floc point.
Air Station Blowdown:
- Removing condensed water from instrument air piping to prevent damage to pneumatic instruments and control valves.

Standby Equipment Operation

Standby equipment must be maintained in a reliable, ready state.
Periodic operational tests are required to ensure standby equipment will work correctly when needed.
Examples of standby equipment include:
- Emergency Generators
- Fire Pumps
- Standby Feedwater Pumps

Emergency Generators

Periodic inspection and operation is required.
Inspection includes oil levels, fuel supplies, and governing controls.
Test runs must include an assessment of the generator's loading capability.

Fire Pumps

Critical for plant safety, test run on a weekly basis.
Inspection and test run include verifying oil levels and pumping capacity.

Standby Feedwater Pumps

May be powered by electric motors, internal combustion engines, or steam turbines.
Must be operated regularly to ensure reliability.

Duty Swap

Distributes wear and demonstrates equipment reliability.
Procedure involves:
1. Starting the incoming piece of equipment while the in-service piece is still running.
2. Checking operating parameters to ensure they match the in-service equipment.
3. Shutting down the in-service piece of equipment when all parameters match.

Safety and Safety Relief Valve Testing

Testing intervals are governed by preventative maintenance schedules.
Safety valves require particular attention as they are critical safety items.

Maintenance Records

Keeping maintenance records is essential.
Methods include paper and electronic filing systems.
Records are used to analyze current and historical equipment performance and make predictions on reliability.
