What acronym indicates flooring on a ship?

The acronym that indicates flooring on a ship is FL. In maritime terminology, FL specifically refers to “floor” or “flooring,” which pertains to the construction and materials used on the decks and other surfaces within the interior of a vessel. Understanding this terminology is vital, especially in shipbuilding and maintenance, where accurate identification of components can be critical.

The other acronyms do not represent flooring. For instance, FW may refer to freshwater, FB could denote fuel bunker or forward bulkhead, while FD might indicate flammable dangerous goods or fire and damage control. However, none of these relate directly to flooring, making FL the appropriate choice for this question.
