る。As described above, according to the maintenance / inspection method for a propulsion device for a ship of the present invention, a support structure that constitutes a part of the bottom structure of the stern and is used when the turning propulsion device is mounted in the ship. The seal part that closes the gap between the frame structure that is to be installed on the ship bottom structure and the bottom opening that is provided to incorporate the frame structure into the ship bottom structure is located above the full load waterline of the ship, and the required size on the upper deck. Since a hatch is provided and the frame and the swing-type propulsion device are hung outside the ship as a block through the hatch to perform the inspection and maintenance work of the swing-type propulsion device, the frame and the swing-type propulsion device are put outboard. Even if the ship is lifted up and an opening is made in the ship bottom structure, it will not be flooded into the ship.Therefore, it will be possible to carry out inspections and maintenance work of the swing-type propulsion device while the ship is in a floating state. Protection It unnecessary to Ueka in dog vessels can reduce the cost and time for,
Further, it is possible to perform the inspection and maintenance work in a suitable working environment outside the ship, and it is possible to perform the inspection and maintenance with high accuracy, which is an excellent effect.

進装置の保守点検方法。1. A structure in which a required size of a ship bottom opening is provided in advance in a part of the ship bottom structure of the stern, and a frame which is inserted into the ship bottom opening to be a part of the ship bottom structure is provided on the peripheral edge of the ship bottom opening. By making it possible to detachably fix it through a sealing material and transmitting rotational power from the input shaft detachably connected to the main engine to the propeller shaft to rotate the propeller attached to the rear end of the propeller shaft. A swivel propulsion device that generates a propulsive force and horizontally swivels the propeller by a swivel drive device is steered is supported, and the seal portion between the frame and the ship bottom structure is located above the full load waterline of the ship. age,
Furthermore, a hatch is provided on the upper deck, and the above-mentioned frame and swing-type propulsion device are carried in and out through the hatch on the upper deck, and maintenance and inspection of the propulsion device of the ship is carried out outside the hull. Method.
