The COASTAL DRILLER, following discharge of preload, should_______________.
AI Explanation
The correct answer is B) close all dump valves.
After the preload is discharged, the dump valves on the COASTAL DRILLER should be closed to prevent any further discharge or leakage. Leaving the dump valves open could allow unintended discharge of fluids or materials, which would be improper and potentially unsafe. Removing or replacing the dump valves is not necessary in this scenario - the appropriate action is to simply close them to contain the system.
The other options are incorrect because A) removing the dump valves is unnecessary, C) replacing the dump valves is unnecessary, and D) leaving the dump valves open would be improper procedure after preload discharge.
