🔍 Key Concepts

• Immediate protection of main turbine and bearings when lube oil pressure is lost • Consequences of metal-to-metal contact in a high‑speed turbine with low/no lubrication • Which action gives the fastest reduction in shaft speed and load to prevent damage

💭 Think About

• If lube oil pressure suddenly drops at sea speed, which action most quickly prevents damage to bearings and turbine surfaces? • Which option focuses on reducing or eliminating rotation under poor lubrication conditions, rather than trying to correct the pressure while still running at high speed? • Think about what happens inside a turbine when lubrication fails at high speed—what is your priority in the first few seconds?

✅ Before You Answer

• Verify which choices directly change shaft speed or rotation versus those that only adjust auxiliary systems (cooling, strainers, tanks). • Consider whether it is safe to continue turning the turbine, even at reduced speed, when you suspect a serious lubrication failure. • Ask: which choice represents an emergency protective action, not a routine adjustment or diagnostic step?

While standing watch, what immediate action should you take if you are running at sea speed and notice a sudden and significant drop in lube oil pressure to the main turbine?

Immediately increase cooling water flow to lube oil cooler.

Slow the turbine to minimum speed and watch the bearing temperatures.

Stop the main shaft using astern steam.

Shift strainers and gravity tanks.
