🔍 Key Concepts

• loss of lube oil pressure and what it means for turbine bearings and shaft surfaces • difference between stopping the rotor and changing direction of rotation • how steam supply to main turbines is normally controlled in an emergency

💭 Think About

• Which action will most quickly remove the driving force that keeps the turbine rotor turning at high speed when lubrication is lost? • Which choice, if taken, could actually increase the risk of damage by keeping the rotor turning or adding load instead of letting it coast down safely? • Think about standard emergency procedures: what is the first thing engineers do when a serious casualty to the main turbines occurs?

✅ Before You Answer

• Verify which option directly removes power/energy input to the main turbine rotor. • Check which action could cause additional mechanical stress or heat on bearings that have already lost lubrication. • Confirm which choice aligns with typical engine room casualty control procedures for turbine plants when lube oil pressure fails.
