🔍 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

Question 1 of 20

Where the size and design of an engine is such that lubrication before starting is not necessary and an attached pump is normally used, __________.

an additional pump is not required provided the engine driven pump is capable of producing sufficient pressure regardless of the direction of rotation

no additional pumps are required if the vessel is equipped with two propulsion engines clutched to reduction gears through a suitable arrangement

an independently driven pump capable of supplying each engine with sufficient quantities of oil during ahead operations is required

an independently driven stand-by pump is not required if a complete duplicate of the attached pump is carried as a spare
