Question 4329Deck General70% to pass
Port ballast pump #1 on the DEEP DRILLER has failed. If you want to deballast the forward-port column using port ballast pump #2, it is necessary to open valves _______________.
AI Explanation
The correct answer is D) 3, 34, 35, 36, 46, and 48.
To deballast the forward-port column using port ballast pump #2, you would need to open valves 3, 34, 35, 36, 46, and 48. This allows the ballast water to be pumped from the forward-port column through port ballast pump #2 and out of the system.
The other answer choices are incorrect because they either omit necessary valves (A and C) or include unnecessary valves (B). The key is to identify the specific valves that need to be opened to properly deballast the forward-port column using the operational port ballast pump.
