Question 1 of 27070

What port-side valves must be open to transfer ballast from Tank 1P to Tank 10P on the DEEP DRILLER using the Port #1 ballast pump?

🔍 Key Concepts

• Ballast system line-up on DEEP DRILLER – know the normal numbering for tank suction and discharge valves • Port #1 ballast pump suction and discharge paths – trace from Tank 1P to Tank 10P only on the port side • Difference between tank suction valves, manifold/branch line valves, and tank fill valves

💭 Think About

• Start at Tank 1P: which valve number normally connects this tank to the Port #1 pump suction header? • From the pump discharge, which valves must be open to reach Tank 10P, and which valves clearly go to other tanks or crossovers you do NOT want to use? • Look at the valve numbers that appear in more than one option – what do those common valves likely represent in the system (suction header, main discharge line, or local tank valve)?

✅ Before You Answer

• Confirm on the DEEP DRILLER ballast diagram which specific valve is the Tank 1P suction valve to Port #1 pump – that valve number must appear in your choice. • Confirm which valve(s) are in the Port #1 pump discharge line leading to the port-side forward/aft tank manifold – those should also be in every correct transfer lineup. • Make sure every valve in your chosen option is actually in the flow path from 1P to 10P on the port side only, and that you are not opening any cross-connect or wrong-tank valve that would send ballast somewhere else.
