🔍 Key Concepts

• Engine room casualty response priorities (protect equipment, maintain propulsion, then report) • Relationship between bearing temperature, lubricating oil flow, and cooling • Difference between immediate actions and follow‑up notifications while on watch

💭 Think About

• Before touching anything, what must you confirm about whether the alarm is real or false? Where would you check? • If a bearing is running hot, what change in load (speed) will most quickly reduce the risk of damage? Think about friction and pressure on the bearing. • When in a machinery emergency, do you first: change operating parameters, check support systems (like coolers/pumps), or communicate? Which protects the equipment fastest?

✅ Before You Answer

• Identify which choice directly addresses the cause of high bearing temperature rather than just the symptom. • Decide whether changing speed or lubrication/cooling systems is the safer first step for the machinery. • Consider standard watchstanding practice: verify system condition locally before or at the same time as any major operational change or report.
