🔍 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.
