Promising Hydrodynamic Improvements For Inland Vessels

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.
