Pre-swirl Type Energy-saving Device

“Eco-Stator” is one of pre-swirl type of energy saving devices installed in front of propeller, which has four or five stator fins fixed radially around stern tube and upper side of propeller shaft. It works as to rectify a water stream flowing around the stern and helps the propeller to enhance its thrust at minimized propulsion main engine output.
Eco-Stator is fitted by welding at shipyard.
