The DEEP DRILLER is loaded as shown in Sample Load Form #4. While the unit is deballasting, port valve 5 fails in the closed position. You may deballast from tank 2P by pumping from tank 9P by also opening valves 6 and __________.

🔍 Key Concepts

• Ballasting/deballasting flow paths on the DEEP DRILLER schematic for Sample Load Form #4 • How valves are numbered in the ballast system (which tanks/lines each valve connects) • Effect of a failed-closed valve on possible transfer routes between tanks

💭 Think About

• On the ballast diagram, trace the normal deballasting route from tank 2P when valve 5 is working. Then, block valve 5 and ask: what alternate path can still connect 2P to 9P? • For each answer choice, find that valve number on the diagram and see exactly which line or manifold it opens. Does that create a continuous path from 2P to the overboard discharge via 9P? • Consider whether the selected valve would accidentally connect to a starboard tank, cross‑connection, or an isolated section of piping that would not help you deballast 2P.

✅ Before You Answer

• Verify on the diagram which single additional valve, together with 6, completes a continuous piping path: 2P → 9P → pump → sea • Confirm that with valve 5 failed closed, the chosen valve does not require any other valve (besides 6) to be opened to make the path work • Double‑check that the valve number you pick is actually in the port ballast line serving tanks 2P/9P, not on a separate branch or starboard line
