One soft grounding scenario - called stranding - is calculated with the FE method.A cargo hold section is modelled with shell elements and the rest of the ship is simulated with beam elements. The ground follows the Mohr-Coulomb material model. The results are compared to a calculation with a rigid ground. The vessel strands within the parallel midship and is subjected to the tide. Due to the water level reduction to half draft the hydrostatic forces significantly change. The correct hydrostatic forces as a function of water level and stranding position are applied. The ship structure collapses and elasto-plastic buckles are the predominant kind of damage. The soil characteristics influence the collapse mode. The damage is spread more globally if the ground is of sand. Therefore it is necessary to model the soft ground. A verification of the calculation method is also presented. © 2013 Taylor & Francis Group.
