🔍 Key Concepts

• Follow the piping path from #6 centerline tank to the main deck manifold and identify which valves are actually in that line • Determine which valves connect to other tanks or the sea chest that should be isolated for this operation • Remember that the question says the #7 main deck manifold valve is already open, so think about what needs to happen between that point and the tank

💭 Think About

• Trace the flow starting at #6 centerline tank and move toward the pump and then toward the deck manifold: which numbered valves must be open for cargo to reach shore? • Which valves, if left open, would allow cargo to flow to the sea chest or other #6 tanks instead of only to the #6 centerline tank? • Compare each answer choice against the line you traced: where would the cargo go with that pattern of open/closed valves?

✅ Before You Answer

• Make sure all valves in the direct flow path from #6 centerline tank to the open #7 manifold are listed as open in the choice you select • Verify that valves leading to the sea chest (ballast/sea line) are closed so cargo does not discharge overboard • Verify that valves to #6 port and #6 starboard tanks are closed if the question wants discharge from only #6 centerline
