Advantages of Twin Rudder System with Asymmetric Wing Section Aside a Propeller : The New Hull Form with Twin Rudders Utilizing Duct Effects

This study presents a new twin rudder system with asymmetric wing section, aside a propeller, as a new category energy saving device (ESD) for ships. The energy saving principle of the new ESD, which is called “Gate rudder”, is described and its applicability on a large bulk carrier is explored using experimental and numerical methods. The study makes emphasis on the cost-effectiveness of the proposed ESD and presents a potential energy saving up to 7-8 % with the new device as well as an attractive return investment in 0.37-0.9 year. These estimations are based on the conventional powering methods, whereas the accuracy of the ESD design method is confirmed by model test measurements.
