The theoretical foundations of the reliability criteria applied to the dimensioning of ship structures are briefly discussed with reference to the semi-stochastic criteria. An original formulation is introduced through its underlying principles regarding mean ultimate compressive strength values. It is shown how this formulation makes it possible, ~n ~he field of both semi-stochastic criteria, to solve design and verification problems (with reference only to the Longitudinal strength) in a simple way. This formulation is applied to a tanker and a rapid computation procedure performed to determine the ultimate bending moment.
