Question 4302Deck General70% to pass
The DEEP DRILLER is loaded as shown in Sample Load Form #4 (Drilling). While the unit is deballasting, starboard valve 17 fails in the closed position. You may deballast from tank 8S by pumping from tank 9S and opening valves 18 and _______________.
AI Explanation
The correct answer is C) 20.
The explanation is as follows:
1. Confirm the correct answer: The correct answer is C) 20.
2. Explain the reasoning: When the starboard valve 17 fails in the closed position, the deballasting needs to be done from tank 8S. To do this, the ballast water can be pumped from tank 9S and the valves that need to be opened are 18 and 20.
3. Explain why the other options are incorrect:
A) 35 is incorrect because valve 35 is not involved in the deballasting process described in the scenario.
B) 21 is incorrect because valve 21 is not the valve that needs to be opened.
D) 17 is incorrect because valve 17 is the one that has failed in the closed position, so it cannot be the valve that needs to be opened.
4. Concise explanation: The correct answer is C) 20 because when starboard valve 17 fails closed, the deballasting needs to be done from tank 8S by pumping from tank 9S and opening valves 18 and 20.
