🔍 Key Concepts

• Gas turbine lube oil system protection and what high lube oil temperature implies for bearings and gears • The difference between power reduction as a temporary response and a shutdown as a protective action • Whether water washing or checking oil consumption are operating responses or maintenance/diagnostic actions

💭 Think About

• If you have already reduced power and the lube oil temperature is still rising, what does that say about the condition of the lube oil system and the safety of continued operation? • Which option most directly protects the turbine bearings and reduction gears from damage due to overheated or breaking‑down lubricating oil? • Are any of the options normally scheduled/maintenance procedures rather than immediate casualty responses?

✅ Before You Answer

• Verify which action is the safest immediate protective measure when an engine parameter continues to trend in the unsafe direction after an initial corrective action • Confirm that water wash is associated with compressor cleanliness and performance, not emergency lube oil problems • Check that oil consumption trends are long‑term indicators and not the primary concern during an active high‑temperature alarm
