The paper presents finite element simulations of a damaged tanker double bottom subjected to bending moment. An important issue is the influence of size and shape of the obstruction on the sea floor during minor grounding events. The initial damage is induced by rigid indenters at various locations and using different sea bottom topologies. The study found an important reduction in the ultimate capacity of the double bottom structure when the initial indentation deforms stiff structural elements such as side girders, whereas more local damage produces similar shortening response independently of the location or shape of the indenter.
