🔍 Key Concepts

• Diesel engine protective devices such as overspeed, low oil pressure, and high lube oil temperature trips are there to prevent serious damage • The difference between immediate actions in an emergency versus a normal protective shutdown where the engine has already stopped safely • Safe procedures for checking high-temperature components and pressurized systems after a trip

💭 Think About

• If the engine shut down automatically on high lube oil temperature, what was the protective system trying to prevent from happening inside the engine? • What personal safety risks exist if you hurry to open crankcase doors, remove covers, or work around very hot, pressurized lubricating oil right after a shutdown? • On a docking tug, how do you balance the need for quick availability of the engine with the need to prevent further damage or injury after a high‑temperature shutdown?

✅ Before You Answer

• Check which options involve immediate restart after a high‑temperature safety trip and consider if that respects the purpose of the protective device • Check which options require you to inspect the engine while it is still very hot or under possible residual pressure, and think about standard safe‑engine‑room practice • Consider which option best matches typical manufacturer/engine-room procedures: cool down, make the area safe, then diagnose and correct the fault before restart

Question 1 of 20

A main propulsion diesel engine on your ship docking tug has experienced a safety shutdown due to high lubricating oil temperature. What is the appropriate response?

Allow 2 hours for the engine to cool down before attempting to inspect the engine and correct the cause of the trip before attempting to restart the engine.

Immediately perform the engine inspections to determine the cause of the high oil temperature safety shutdown.

Immediately restart the engine, and monitor the oil temperature to verify the cause of the shutdown.

Allow the engine to cool off for two minutes, then restart and monitor the lubricating oil temperature to verify the cause of the shutdown.
