Development of Fuel Saving Device for the Twin Screw Car Ferry

In this paper, the development results of energy saving device for 57m class strut supported twin screw car ferry has been presented. The series of theoretical calculation with CFD code of Ship flow for some variations of strut fin were performed, and model test in towing tank has been carried out with selected device. The result of towing tank test shows up to 6% power gain in full load condition of design speed of 10Kts.
