dc.description.abstractIn this research, an evaluation of a frontal collision of a tanker with bulbous bow against a rigid structure was performed by reproducing experimentally this scenario in reduced scale and by numerical modeling using the finite element method. The purpose of this analysis was to evaluate the impact force and structural collapse mode of the bulbous bow. A model of an oil tanker in a reduced scale of 1:100 was fabricated for the collision test based on a simplified geometries of naval structures made of mild steel sheets. Similarity laws, developed particularly for structural impact, were presented and employed to predict the mechanical response of a real scale collision accident from the reduced scale test results. Advantages, challenges and limitations in fabrication and employment of reduced scale models were also commented. A finite element model of tanker collision against a rigid wall was also presented. The material model took the mechanical properties of naval steel into account, under static and dynamic loading. The collapse mode appearance of the bulbous bow observed in the numerical modeling resulted to be analogous with experimental results in reduced scale. Furthermore, results obtained from experimental and numerical approaches were compared with empirical formulae of impact force when a ship collides a bridge pier showing a good agreement and demonstrating the potential of using reduced scale ship models in collision evaluation.
