Question 1153Deck General70% to pass
If your Bunker-C barge has operated in salt water for more than 12 months in the 24 month period since it was last dry-docked, when is it required to be hauled out again?
AI Explanation
The correct answer is B) 30 months since last dry-docking.
According to the US Coast Guard regulations, a Bunker-C barge that has operated in salt water for more than 12 months in the 24 month period since it was last dry-docked is required to be hauled out again within 30 months of the last dry-docking. This is specified in 46 CFR 31.10-21, which requires an underwater survey or dry-docking at intervals not exceeding 30 months for vessels that operate exclusively in salt water.
The other options are incorrect because A) 36 months is too long, C) 18 months is too soon, and D) 12 months since last dry-docking does not account for the 24 month period of salt water operation.
