A longitudinal framing system contains numerous, closely spaced transverse frames and few widely spaced longitudinal structural stiffeners.

• A. True
• B. False
• C. Not Standardized
• D. Cannot Determine

Answer: (B)

Longitudinal framing is built around stiffeners that run along the length of the hull (longitudinals) complemented by transverse frames that shape the hull cross-section. To provide sufficient cross-sectional stiffness and keep the shell from deforming, many transverse frames are placed at relatively short intervals, while the longitudinal stiffeners are fewer and spaced farther apart. This distribution means the hull girder gains most of its stiffness from the network of transverse frames, with the longitudinals carrying load along the length but not needing to be as densely spaced. So describing numerous, closely spaced transverse frames and few widely spaced longitudinal stiffeners matches how a longitudinal framing system is normally configured, making the statement true.
