What term describes the structural framework of a ship?

The term that describes the structural framework of a ship is "frame." In shipbuilding, frames serve as the skeleton that supports the vessel. They are typically made of steel or other strong materials and are essential for maintaining the shape and integrity of the ship. The frames run vertically and horizontally across the vessel, providing the necessary strength to withstand the stresses of the sea and the weight of the ship itself.

While compartments refer to the enclosed spaces within a ship, such as cabins or engineering spaces, and decks refer to the horizontal surfaces on which crew and equipment are placed, these terms do not capture the notion of the underlying structure that frames provide. Bulkheads are vertical partitions that separate different spaces within the ship but also do not represent the overall framework. Therefore, "frame" accurately identifies the critical structural elements that contribute to the ship's durability and design.
