If you are notified that one of the turbine bearings is overheated, which of the following actions should you take first as the watch engineer?

🔍 Key Concepts

• Turbine bearing overheating – what it usually indicates about lubrication and metal-to-metal contact • Lube oil system role – how lubrication, flow, and pressure protect bearings • Difference between reducing/stopping the turbine vs. correcting the cause of overheating

💭 Think About

• Before changing speed, ask: what most commonly causes a bearing to overheat in a turbine system? • Which action gives you the earliest indication of actual bearing damage (not just high temperature)? • Which option addresses both lubrication quality and evidence of damage rather than only changing load or cooling?

✅ Before You Answer

• Identify which choice directly checks for bearing damage indicators (e.g., metal particles) instead of only changing operating conditions. • Decide whether it is safer to immediately shut down or to first assess the condition while still maintaining control of the machinery. • Confirm which system (lube oil vs. cooling water vs. turbine speed) is the primary protection for bearings under normal operation.

Immediately reduce speed.

Immediately stop the turbine.

Increase lube oil pump discharge pressure and check the strainer for metal particles.
