The study on the design of pre-swirl stator vanes is performed. The pre-swirl stator vanes is an energy-saving device to improve propulsive performance by providing pre-swirl to the propeller inflow. The theoretical background and the design conditions for pre-swirl stator vanes are presented. The flow characteristics around the pre-swirl stator vanes attached ship hull are analyzed through the experimental method. The technique to determine the optimum location, angle and the number of stator vane is investigated and applied it to 310,000 TBW VLCC The flow velocities are measured using 5-hole Pilot tubes at the condition with and without a propeller.
