When filling fuel-oil tank 6P on the DEEP DRILLER, it is necessary to open valve _______________.
AI Explanation
The correct answer is D) 12.
When filling fuel-oil tank 6P on the DEEP DRILLER, it is necessary to open valve 12. This is because valve 12 is typically the valve that controls the flow of fuel to the fuel-oil tank 6P. The other valve options (9, 10, and 11) may control the flow of fuel to other tanks or systems on the vessel, but valve 12 is the one specifically associated with filling fuel-oil tank 6P.
The other answer choices are incorrect because they do not correspond to the valve that controls the flow of fuel to the specific tank being filled (6P) on the DEEP DRILLER.
