The retractable c.p. impellered thruster developed this time is so mechanized that it shall be put out of the hull bottom into seawater with freely controllable thrust and the direction of the thrust at any rotated direction by 360 degree. The thruster can be said effective as self-propulsive propeller for ships running at low speed in case of necessity or as dynamic positioning apparatus for oil rig operating in the deep sea.<BR>As the basic experiments, using the model thruster prepared, systematic experiments were carried out in the model basin, and the data required for designing the retractable thrusterr were obtained. On the other hand, the sea trial using the prototype thruster were carried out for confirming its retracting, rotating and pitch controlling characteristics. Thus, the technical information necessary for the application of the thruster to the ship were successfully obtained.
