🔍 Key Concepts

• Steam turbine lubrication systems for main engine, including main, standby, and emergency supply • Purpose and location of a gravity lube oil tank in relation to turbine and reduction gears • What happens to bearings (turbine and reduction gear) when oil pressure is lost and how fast damage occurs

💭 Think About

• Think about what the ship’s designers expect to happen if both the main and standby lube oil pumps fail at sea—what backup arrangement would give you a few moments to safely secure the plant? • Consider which components are most critical to keep lubricated during a sudden loss of pump pressure: are they designed to fail instantly, or to be protected long enough to shut down? • Ask yourself which option describes a realistic, permanently installed emergency feature of a turbine plant, rather than a method that would be too slow or impractical while underway.

✅ Before You Answer

• Verify which items in the choices are permanently installed emergency systems commonly fitted on turbine plants (not just portable tools). • Check which components are normally fed from a gravity lube oil tank and what that tank is intended to allow the operator to do in an emergency. • Confirm whether any system relying on a hand pump could realistically protect high‑speed turbine and gear bearings during sudden loss of main lube oil pressure.

If the main and standby lube oil service pumps of the main engine fail while underway at sea, __________.

emergency lubrication can be supplied through the use of the hand pump

the reduction gear bearings will immediately fail

the turbine bearings will immediately fail

an emergency supply of oil in the gravity tank will provide time to crash stop the turbine and gears
