🔍 Key Concepts

• Starting procedures for turbo-generators on ships • Purpose of lube oil pressure to the governor power piston during start-up • Difference between main, auxiliary/hand, and gravity-fed lube oil systems

💭 Think About

• Think about which pump or system is available and reliable before the turbo-generator is turning and its main pump can build pressure. • Ask yourself: Which option can provide lube oil pressure independently of the turbo-generator’s own rotation? • Consider which choice is specifically intended for pre-lubing and initial governor control during start-up, not during normal full-speed operation.

✅ Before You Answer

• Verify which pump or system can operate without shaft or turbine rotation. • Check which system is normally used for pre-lubrication and bringing up oil pressure before rolling machinery. • Eliminate any choices that depend on the turbo-generator already being at operating speed to develop pressure.
