Abstract： This report gives a comprehensive summary of research work on outboard azimuthing propulsors in 2013. The concept design and detailed design of original prototypes were completed with a concepet design review. The preparation for detailed design review was also completed. In the project the propulsion system was divided into three parts， general design， azimuthing device and deep-sea motor respectively. During the year higher efficiency duct and tunnel propeller were designed in the general design system， structural design of azimuthing device and azimuthing controller and positioning were achieved， three deepwater motors were designed as well. By completing the design and research works hydrodynamic loading analyzing technique of azimuthing ducted propeller based on computational fluid dynamics was developed， power transmission technique of deep-sea motor applying magnetic coupling and direct drive was investigated， Sealed and positioning technique of deep-sea azimuthing device applying higher precision dual lead worm and gear were developed as well. Based on the calculated results and model test the technical criteria of the original prototypes were predicted and can meet the requirements.

Key Words： Azimuthing device； Higher efficiency duct； Tunnel propeller； Deep-sea motor； Positioning
