Reference Answer
(a) Mid-ship half-section sketch of a container ship:
(b) Structural Strength Features:
The deck plating is made thicker and uses higher tensile steel to withstand stresses caused by wide hatch openings and operational loads.
The deck, side shell, and longitudinal bulkheads are framed longitudinally . This arrangement combined with deep double bottom helps resist bending stresses due to hogging (upward bending) and sagging (downward bending) when the ship is under load.
