Question 1 of 205eccefa1bacbc34ba4d47316

Upon assuming the watch on a steam ship while cargo operations are in progress with the main engine and reduction gear secured, you notice a very large increase in the reduction gear lube oil sump level from previous log book entries. What would be the most probable cause of this large increase in sump level?

🔍 Key Concepts

• Reduction gear lube oil system layout (sump, pumps, gravity tank, coolers, bypass lines) • What happens to sump level when oil is added to versus removed from the system • The effect of vessel trim on level readings in a large, wide sump

💭 Think About

• For each choice, ask: would this realistically cause a large INCREASE in the sump level, a decrease, or almost no change? • Think about the purpose of a gravity tank: when it is empty, where did that oil come from or go to, and what does that do to the sump? • Consider what a service pump bypass actually does with pump discharge and how that might change the amount of oil returning to the sump.

✅ Before You Answer

• Identify which options would clearly tend to raise the sump level versus lower it. • Decide whether a slight change in trim could reasonably explain a "very large" increase in level. • For the gravity tank, verify whether it being empty would make the sump level go up, go down, or stay about the same.
