abstract = {Shallow water effects change the flow around a ship significantly which can affect the optimum design of the hull. This paper describes a study into the optimization of the aft ship region for various water depths. The research focuses on variations of the following parameters of a hull form: The athwart ship’s propeller location, the tunnel top curvature, the flat-of-bottom shape in the stern region and the stern bilge radius. All hull form variants are evaluated in 3 different water depths using a viscous flow solver, and a surrogate model is created for each water depth. Pareto plots are used to present the trade-off between the optimization for one or another water depth. Finally, specific hull forms are chosen and the differences in flow behavior among hull forms and water depths are explained.},

abstract = {In the EU project Move IT! and the Joint Industry Project SAVE, extensive CFD calculations have been performed for several existing inland vessels. The objective was to investigate possible retrofit options to improve the hydrodynamic performance, and to determine the potential reduction in fuel consumption. This paper presents the results of the CFD calculations performed for the vessels. Different bow shapes have been analysed and a detailed investigation was performed on the shape of the aftship, especially focussing on the tunnel design. Some of the improvements were very promising and provide an interesting basis for inland ship design in general.
