The project has been a joint research and development of methods for dynamic designs of ship to increase the knowledge about how dynamic loads on ships affects the structural response. The project is a cooperation between Chalmers University of Technology (CTH), The Royal Institute of Technology (KTH), SSPA Sweden AB and Stena Teknik AB. Stena Teknik AB have been supporting the project with drawings and structural properties of the concept ship Stena Electra, as well as contributed with their experience as a shipowner. A segmented lightweight ship model made of carbon fibre, divinycell and aluminium was designed and built. Dynamics structural loads, forces and moments, as well as deflections of the ship could be measured, making it possible to assess the impact of waves on the ship structure. The structural properties of the model, such as stiffness, mass distribution and structural damping met the targets of the full-scale ship. Model test have been performed in order to evaluate the model concept and to compare with corresponding numerical simulations. Numerical analysis of hydrodynamics and structure have been performed and compared with the model tests. A quasi-static hydrodynamic numerical approach was utilized.
