The scope of this study is to investigate the possibilities for applying Gravity Base Foundations at larger water depths. To do so the influence of various parameters for the foundation and turbine are investigated as well as the properties of the sub soil. It is concluded that it is technically possible to construct concrete Gravity Base Foundations for larger water depths, but due to the increase of the foundation weight the handling of the foundations and the bearing capacity of the sub soil are the aspects that are determining the applicability to a large extend.
