Question 5057 Deck General

The correct answer is D) 41. To pump bilge water out of the port pump room using both bilge pumps on the DEEP DRILLER, valve 41 must be opened. This is because valve 41 is the valve that controls the discharge of the bilge water from the port pump room. By opening this valve, the bilge water can be pumped out of the port pump room using both bilge pumps. The other answer choices are incorrect because they do not represent the valve that controls the discharge of bilge water from the port pump room. Valves 26, 28, and 36 likely serve other purposes on the vessel, but they are not the specific valve required to be opened to pump out the port pump room.
