🔍 Key Concepts
• Diesel engine preventive maintenance and what "routine monitoring" means
• Common signs of developing engine problems (visual, audible, and on gauges)
• Why engineers always monitor more than one type of indicator (e.g., leaks, gauges, sounds)
💭 Think About
• When you are on watch with a running diesel, what are the different ways you can detect a problem early before it becomes serious?
• Does safe operation focus on only one type of check, or a combination of checks (visual inspections, gauges, and sounds)?
• If one of the listed checks were ignored completely, could that lead to a hazardous or expensive failure that would otherwise be easy to catch?
✅ Before You Answer
• Make sure you consider all the senses and instruments an engineer uses: sight, hearing, and gauge readings.
• Ask yourself: is any one of the listed options unnecessary during normal engine-room rounds, or are they all standard practice?
• Think about typical engine-room watchstanding procedures: what does the checklist usually include on every round?
