Hull girder ultimate strength on four ISSC benchmark vessels is analyzed by using proposed simplified formulae, where a computer code NEPTUNE is developed. The moment–curvature curve and the ultimate bending moment at ultimate state are calculated with initial imperfections in the form of geometric deflection and welding-induced residual stresses for both hogging and sagging cases subject to vertical bending. The accuracy of adopted procedure is examined by seven different methods on the examples used in the benchmark calculations. Finally, results and insights derived from this study are summarized.
