Accordingly, the present invention is to provide a marine propulsion device having the following features to achieve the above problems.

That is, in the present invention, the main propulsion force of the vessel is obtained by rotating the rear screw by the rotational force of the turbine operated by the high-pressure steam generated by heating the seawater to obtain the main forward and backward movement force, and the secondary propulsion force is formed in the outer side of the hull. The high pressure steam is injected into the nozzle to increase the forward propulsion of the hull, and bubbles are formed between the hull and the seawater to reduce the friction force when moving forward.

By selectively opening and closing each nozzle installed on the front, rear, left, and right sides of the hull, the lifting force of the ship's forward injection reaction is canceled to offset the hull shake caused by the waves and the center restoration movement to stabilize the hull posture. Edo provides a ship propulsion system capable of self-driving while tracking the indicated berth of the pier.

In addition, the horizontal nozzles installed at the front, rear, left and right sides of the hull allow the ship to move left and right, allowing self-anchoring and transiting without the help of a tugboat when docking.

Considering the reality of the port authorities, which all ports of today have exceeded the ship handling capacity, ships equipped with the ship propulsion system of the present invention that can be self-driving and general ships have great economic competitiveness in terms of entry and departure port and time.

Later, the injection nozzle control is controlled by a computer so that the optimum steam pressure of each nozzle can be injected accurately and quickly.

In addition, the engine 1 of the ship 1 supplies steam pressure generated by heating seawater from two turbine boilers 2 and injection boilers 6 for burning heavy oil and the like to supply the turbine 3 with the rotational power of the screw 4. To each nozzle to produce a jetting force.

Of course, the injection boiler can be additionally expanded and operated in consideration of the required speed of the vessel 1 or the vessel load.
