In terms of ship construction framing methods, what statement is true concerning the longitudinal framing system?

Correct Answer: Option A — With longitudinal framing, longitudinal frames are horizontal and continuous and vertical stiffeners are intercostal between frames.

Longitudinal framing systems feature continuous horizontal frames running fore and aft to provide superior longitudinal strength. In this configuration, vertical stiffeners are installed intercostally between the continuous longitudinal frames, effectively distributing loads and preventing shell plating buckling under hogging or sagging stresses.
