Question 4300 Deck General

The correct answer is A) 2. When flooding through the overboard discharge into ballast tank 1S on the DEEP DRILLER, valve 2 on the starboard side needs to be opened. This is based on the design and configuration of the vessel's flooding and ballast control systems, which are critical knowledge for Coast Guard license exams. The other answer choices are incorrect because valve 3 is likely for a different purpose, valve 7 may be for a separate system, and valve 37 does not correspond to the specific valve that must be opened in this flooding scenario on the DEEP DRILLER.
