ABSTRACT:
A process for reducing the stresses in a vessel consisting of building a hull with a number of compartments and fitting into each an independent cargo tank for the storage of liquefied gas. Before the cargo tanks are fitted, the hull in the region of each compartment along the central transverse section thereof is subjected by ballasting to a predetermined vertical static bending moment in the absence of the tank, and thereafter each tank is installed in the hull while maintaining the predetermined vertical static bending moment so that the maximum stresses to which the tank will be subjected under different sailing conditions will be substantially reduced.
