Question 1 of 2066636eef28f7522a1c5200de

In preparation for getting an offshore anchor handling vessel underway, what is the primary factor to consider in determining when it is prudent to increase the main propulsion engine rpm above idle and place a load on the engine? (Assume that there are no starting aids.)

🔍 Key Concepts

• Warm-up requirements for large diesel propulsion engines before applying load • Importance of thermal expansion and lubrication conditions during start-up • Which engine parameters most directly indicate that internal moving parts are ready for higher rpm

💭 Think About

• When a large diesel has just been started from cold, which system reaches a safe operating condition first: lubricating oil, jacket water, or cooling water pressure? • Which parameter best reflects that clearances between bearings and journals are correct and that metal-to-metal contact is minimized? • Of the four choices, which one would most quickly indicate that it is safe to increase rpm without causing excessive wear or scuffing?

✅ Before You Answer

• Identify which parameter is most directly tied to bearing protection and friction reduction at start-up. • Distinguish between indicators of temperature/clearance readiness versus simple system presence/flow (e.g., level or pressure alone). • Ask: which reading, if too low, would most immediately risk severe engine damage when increasing rpm from idle?
