The input data for the time variant reliability calculation of the hull girder contain uncertainties. The level of uncertainty of the calculated hull girder probability of failure depends on the accuracy in the probabilistic presentation of all parameters, including hull girder geometric properties. In the paper, all hull girder geometric properties used in calculation of its bending, shear and torsion stresses are presented by their annual probabilistic distributions and probabilistic distributions for any given time period. A proposal is made for simplifying the calculations using the probabilistic distribution of the hull girder elastic section modulus (deck) as a representative of the probabilistic distributions of all other hull girder geometric properties. The example given is for a bulk carrier.
