... rudder and the twin rudder on propeller performance have been conducted and analyzed. INTRODUCTION Over the years, Energy Saving Devices (ESDs) have been designed in order to improve the propulsive efficiency of ships and reduce the emissions of greenhouse gases from ships. In recent years...

... to the ship motion and added resistance of the ship. The wake profile and the vortex behavior at the propeller plane have definite influence on the propeller performance and hence on the fuel consumption as well. Development of the ship motions and added resistance predictions, by many analytical methods...
