In the maritime sector, the collision safety is an essential aspect of ship operation. Aiming at further improvements, the filling of the cavity in a double hull structure with granular material is investigated in this thesis. In order to do so, the potential of different granules is determined experimentally, along with the description of their material parameters as particles and as a bulk material, respectively. Furthermore, a simplified side hull structure is designed for experimental testing, followed by a numerical study of different material models for the granules. This leads to the simulation of a realistic collision scenario, showing the potential in the maritime industry.
