Description: The subject of this report is a proposed new surface ship hull concept consisting of a double      skin that wraps around the bottom, sides and main deck. The two skins are connected by      plates normal to the surfaces, forming a cellular structure similar to a cardboard box. Modeling      the ship hull as a circular cylindrical orthotropic shell surrounding an elastic core, we are able      to obtain analytical formulas for estimating the principal stresses in such a structure, subjected      to end bending moments and lateral pressure. These formulas indicate that the stiffness of the      proposed bulkheads in the proposed design could be reduced by a factor of 10 without      incurring significant secondary stresses in the double hull.
