While a vessel is underway, which of the conditions listed would indicate a tube leak associated with the sea water-cooled lube oil cooler on service?

🔍 Key Concepts

• Heat exchanger (tube cooler) leaks between sea water side and lube oil side • How water contamination in lube oil shows up in shipboard systems • Difference between an immediate operating symptom and a long‑term consequence

💭 Think About

• When a tube leaks in a seawater‑cooled lube oil cooler, which fluid is more likely to get pushed into the other, based on typical pressures? How would that show up in the lube oil system? • Which of the listed choices would you notice first while the vessel is underway and systems are being routinely monitored, before any serious damage occurs? • Think about what the lube oil purifier actually removes. If seawater is getting into the oil, what change in purifier operation or discharge would you expect?

✅ Before You Answer

• Identify which options describe direct, short‑term signs of seawater entering the lube oil, versus indirect, long‑term damage that would occur later. • Consider what you would actually see in the lube oil samples, sight glasses, and purifier discharge if a cooler tube started leaking. • Eliminate any choices that do not specifically indicate water getting into the lube oil system due to a cooler leak.
