Turnaround Maintenance
Turnaround maintenance is a large, planned facility or process outage used to complete major inspection, repair, replacement, modification, and compliance work.
What this term means in maintenance
Turnaround maintenance is a large, planned facility or process outage used to complete major inspection, repair, replacement, modification, and compliance work.
Turnaround versus routine shutdown
A turnaround is normally larger, longer, and more complex than a routine maintenance shutdown. It may involve extensive contractors, statutory inspections, capital modifications, and major equipment opening.
Typical turnaround work
Examples include:
- Vessel inspection
- Catalyst change
- Heat-exchanger cleaning
- Piping replacement
- Major rotating-equipment overhaul
- Instrument upgrades
- Relief-device testing
- Structural repair
Planning stages
Turnaround preparation may begin months or years in advance and include:
- Scope development
- Engineering
- Procurement
- Contractor selection
- Work packs
- Schedule development
- Risk review
- Material staging
- Execution
- Startup
- Post-turnaround review
Practical example
A process plant stops for three weeks to inspect pressure equipment, overhaul compressors, replace piping, and implement approved engineering changes.
Common mistake
Allowing uncontrolled scope growth close to execution can increase cost, congestion, duration, and startup risk.
