In this paper, a method is proposed for determining the wave-induced hull girder loads used in strength assessment of aging ships for any remaining service life and any probability of exceedence. The hull girder geometric properties are presented in a probabilistic format. The probabilistic distribution of the hull girder stresses is then obtained by the rules of the composition of the distribution laws of the constituent variables. The method allows for assessing not only the absolute values of the stresses but also their level of uncertainty/certainty. An example is given for the deck bending stresses due to wave-induced bending moment.
