A simplified FEM-based (Finite Element Method) approach is proposed to calculate the ultimate hull girder strength of a tanker ship hull. In this approach, instead of modelling and analysing the whole hull girder by means of non-linear FEM, the hull girder transverse section between two adjacent transverse webs is divided into large stiffened panels, which are subjected to longitudinal stresses due to imposed bending moment. The stress-strain curves of these stiffened panels are obtained by non-linear FEM and stored in a numerical database. A progressive collapse analysis program is developed and used to estimate the non-linear behaviour of the ship hull girder using this numerical database with the behaviour of each stiffened panel. The results obtained using this approach are compared with the analytical incremental-iterative method proposed by the IACS Common Structural Rules (IACS-CSR) to evaluate the hull girder ultimate strength using analytically derived stress-strain curves for stiffened plate elements, hard corners and plate elements.
