Question 3207 Deck General

The correct answer is C) 20. To explain: 1. When port valve 5 fails in the closed position, the vessel needs to deballast from tank 2P. To do this, the vessel must open valves 6 and 20 to pump from tank 9P. 2. This is the correct procedure based on the vessel's load configuration in Sample Load Form #4 and the requirement to deballast from tank 2P when port valve 5 fails. 3. The other options are incorrect because they do not match the necessary valves that need to be opened to deballast from the appropriate tank given the failure of port valve 5. 4. The explanation provides the necessary information to confirm the correct answer and the reasoning behind it.
