Question 1 of 27070

On the DEEP DRILLER, when using the starboard #2 ballast pump to provide water to the main deck from the sea, it is necessary to open valves __________.

🔍 Key Concepts

• Review the ballast system line-up diagram for the DEEP DRILLER, focusing on the starboard #2 ballast pump discharge line routing. • Identify which valves connect sea suction to the pump and which valves route pump discharge to the main deck. • Understand the difference between valves in the sea chest/suction side, manifold/selection valves, and overboard or deck service lines.

💭 Think About

• Start at the sea and trace the flow of water through the starboard #2 ballast pump to the main deck connection. Which specific valves must be open for a continuous path? • Compare each answer choice to the piping diagram: which choices include a complete path from sea suction, through the pump, through the correct manifold, and up to the main deck hydrant? • Ask yourself: are any valves in a choice clearly for a different service (e.g., different pump, different side, or overboard discharge) rather than main deck supply?

✅ Before You Answer

• Verify which numbered valves are on the suction side of the starboard #2 ballast pump and must be open for it to take suction from the sea. • Confirm which specific valves send the pump’s discharge to the main deck and not to another destination (like another tank or overboard). • Double‑check that every valve in the selected option is actually in the starboard #2 ballast to main deck line and that you are not missing any valve in that path.
