🔍 Key Concepts

• Pre-lubrication requirements for main propulsion engines under 46 CFR (engine-room regulations) • Differences between engine-driven lube oil pumps and independently driven (motor-driven or shaft-driven) pumps • What the regulation assumes about oil pressure when the engine direction of rotation changes (ahead vs astern)

💭 Think About

• Ask what the regulation is trying to prevent when it talks about lubrication "before starting". What specific casualty is it worried about? • Consider how oil pressure is maintained when the engine is turning in both directions. Which option guarantees proper lubrication regardless of ahead or astern operation? • Look for the answer choice that directly addresses the special condition in the stem: an engine that does NOT need pre-lubing and uses an attached pump. Which choice is focused on that exact situation, without adding unrelated conditions?

✅ Before You Answer

• Verify which choice ensures adequate oil pressure in both directions of rotation for the attached pump • Check which option fits exactly the condition stated (no pre-lube needed, attached pump normally used), and does not introduce new assumptions (like extra engines or spare pumps) • Confirm that the correct choice aligns with the regulatory intent: continuous, reliable lubrication at all times the engine is operating, especially at starting and during direction changes
