It would be prudent to perform which of the following actions prior to the commencement of bunkering?

Correct Answer: Option D — plug the scuppers

33 CFR 155.310 requires that scuppers be effectively plugged during oil transfer operations to prevent accidental discharge into the water. Plugging scuppers ensures that any minor spills or leaks remain contained on the deck, allowing for immediate cleanup before they can reach the marine environment.
