Which of the following conditions is the engineer's FIRST warning that the main lube oil pump has stopped?

🔍 Key Concepts

• Normal sequence of indications when lube oil pressure is lost on a main engine • Purpose and location of a gravity tank and an overflow bull’s-eye in a lube oil system • Difference between an alarm based on pressure/level and a condition that occurs only after damage/overheating

💭 Think About

• Ask yourself: what changes immediately when the main lube oil pump stops: pressure, level, or temperature? • Which indicator is designed to show loss of flow/pressure right away, and which ones would only show up after some time passes? • Which device or observation would the watch engineer most likely notice first while normally monitoring the lube oil system?

✅ Before You Answer

• Identify which options are alarms and which are visual/operating condition observations. • Think about which part of the system is directly dependent on pump discharge pressure versus stored oil in a tank or sump. • Consider the time delay: which options reflect early warning versus consequences that appear only after lubrication has already been lost?
