Q

On a propulsion marine gas turbine, if full power temperatures become excessive, what action should the operator take?

🔍 Key Concepts

• Turbine inlet temperature limits and why they matter for gas turbine life and safety • Difference between immediate operator actions and maintenance actions (water wash, borescope) • Role of temperature limiting and auto‑shutdown protections on propulsion gas turbines

💭 Think About

• Ask yourself: When you see any parameter exceeding limits (like temperature or RPM), what is the very first, safest operator control available to you from the console? • Which options in the choices are normal underway maintenance, and which are inspections that require shutdown and shore support? • Is it good operating practice to deliberately stay at a condition where an automatic shutdown will soon occur, or should you adjust something earlier to prevent reaching that point?

✅ Before You Answer

• Identify which choices are maintenance/inspection tasks versus immediate operating actions • Consider standard engineering standing orders: when an engine parameter approaches or exceeds a red‑line, what are you required to do from the watch station? • Verify which response best keeps temperatures within prescribed limits rather than waiting for damage‑control systems to act
