The DEEP DRILLER is loaded as shown in Sample Load Form #5 (Survival). While the unit is deballasting, port valve 5 fails in the closed position. You may deballast from tank 2P by pumping from tank 1P after opening valves 6 and __________.

Correct Answer: Option D — 2

Cross-flooding and ballasting manifold routing diagrams for the DEEP DRILLER permit alternative suction paths when primary valves fail, allowing tank 2P deballasting through tank 1P by aligning internal piping via open valves 6 and 2.
