A large ship comprises a hull and several cargo tanks. Each cargo tank has substantially semi-spherical bottom and top portions; the bottom portions of the tanks and the top portions of tanks all being of substantially equal radius of curvature. At least one tank has a substantially cylindrical intermediate portion that interconnects the bottom and top portions of the tank and is of substantially equal radius of curvature to the bottom and top portions of the tanks.

A large spherical vessel is produced by welding commercially available large plane metal plates together to form a composite plane plate, cutting the composite plane plate to a form adaptable to a spherical surface, and thereafter forming the resulting composite plate blank to spherical form.
