🔍 Key Concepts

• Shell-and-tube lube oil coolers construction and which fluid normally goes through the tubes • How cooling water flow is controlled to avoid air binding and maintain heat transfer • Whether vital systems like main lube oil cooling may be safely bypassed under different sea water temperatures

💭 Think About

• Think about which side (oil or water) is easier to inspect and clean if there is fouling or scale. Which fluid would you more likely put inside the tubes? • Consider the consequences of bypassing the lube oil cooler on bearing clearances and oil viscosity. Would warmer sea water ever be a reason to bypass cooling? • When you throttle or regulate the cooling water, does it make more sense to adjust the inlet or outlet to avoid pockets of air and maintain positive pressure through the cooler?

✅ Before You Answer

• Verify the typical type of heat exchanger used for main propulsion lube oil (shell-and-tube vs cross-flow). • Check standard practice for cooling water routing: is the higher-pressure, dirtier, or more viscous fluid usually in the tubes or around them? • Confirm whether coolers on essential systems are normally bypassed in operation, and under what (if any) special conditions this would be allowed.
