Question 1861Navigation General

The correct answer is B) Single hull. A single hull tank barge is constructed with the structural framing inside the cargo tank and the side shell plating containing the cargo. This design provides structural integrity while keeping the cargo separated from the external shell. In contrast, other options are not accurate descriptions of this tank barge configuration: A) Shell plated refers to a different construction method not specific to tank barges. C) Independent tanks are separate cargo containment units, unlike the integrated structural framing of a single hull design. D) Hopper type refers to the shape of the barge, not the internal framing.
