Q

When filling fuel-oil tank 6P on the DEEP DRILLER, it is necessary to open valve __________.

🔍 Key Concepts

• Fuel transfer system diagrams for the DEEP DRILLER • Numbering and location of fuel-oil valves and tanks • Flow path from the bunker connection or pump to tank 6P

💭 Think About

• Trace the piping on the fuel-oil system diagram from the source (pump or manifold) to tank 6P. Which valve must be open for fuel to actually enter 6P? • Check whether any intermediate valves must also be open, and then focus on the specific valve that directly controls flow into tank 6P. • Compare the valve numbers near 6P. Which one is positioned on the line leading into the tank you are filling, rather than on a different tank or return/bypass line?

✅ Before You Answer

• Verify the exact label of tank 6P and confirm you are following the correct line on the diagram (port vs starboard). • Confirm which valve number is immediately upstream of tank 6P’s inlet on the diagram. • Make sure you are not choosing a valve that only controls a branch to another tank or a stripping/return line instead of the filling line.
