Container ships are highly subjected to torsional moments because of their very large hatch openings. This leads to even higher warping stresses at the corners of the openings due to lack of torsional rigidity. The upper part of the double hull in such ships is fitted with torsion box. Torsion boxes are fitted with welded joints on the side shell as on the deck plating which prevent the torsion produced by twisting.
