The procedure for repairing a ship using the floating dock for ship repair according to the embodiment of the present invention configured as described above is as follows.

First, the ship (R) to be repaired by operating the propulsion engine 130 in a state in which the seawater storage spaces S1 and S2 inside the dock body 110 are empty (floating in the state shown in FIG. 5). Sail nearby. In this case, the dock body 110 is all made of FRP material, so that the light and solid ballast 170 to obtain a suitable draft and trim can be sailed near the ship (R) (that is, 'ballast sailing' is possible) . At this time, the gate 160 is closed so that the sea water does not flow into the ship receiving space (S3) to facilitate navigation.

Next, the opening and closing device 170 of both vertical portions 112 are synchronously operated near the ship R to lift the gate 160 to open the gate 160. At this time, as the control motor 171 is driven, the screw 172 rotates and the moving block 173 is raised, so that the gate 160 rises under the guidance of the vertical guide part 115b of the guide member 115. 4 illustrates a state in which the gate 160 is closed, and FIG. 7 illustrates a state in which the gate 160 is open. As shown in FIG. 7, when the gate 160 is completely open, the gate 160 is hung by the guide member 115 by a predetermined length.

While opening the gate 160, opening a valve to allow seawater to enter the seawater storage spaces S1 and S2 and increasing the weight of the dock body 110 with seawater allows the dock body 110 to submerge below sea level H. (Shown in FIG. 7).

In such a state to enter the repair target vessel (R) into the vessel receiving space (S3) through the opening 113 of the dock body 110, or by operating the propulsion engine 130 to move the floating dock (100) The ship to be repaired (R) is adjusted to be located in the ship receiving space (S3). 6 illustrates a state in which the dock body 110 is submerged and the ship R is located in the ship receiving space S3.

Next, when the seawater in the seawater storage spaces S1 and S2 is emptied by operating the pump 120, as shown in FIG. 5, the dock body 110 is raised to remove the seawater in the ship accommodation space S3 and R is seated on the seating board 114. Then, the gate 160 is closed so that the sea water does not flow into the ship receiving space (S3). At this time, if the seawater in the ship receiving space (S3) is not completely drained by operating a pump (not shown) to empty the ship receiving space (S3) to facilitate the ship repair work.

Repair the ship (R) using the crane 150 in this state, and when the repair is completed, submerge the dock body 110 in the reverse order of placing the ship (R) in the ship receiving space (S3) After moving the repaired vessel or moving the floating dock 100, the floating dock 100 is floated again and the gate 160 is closed as necessary.

Floating dock for ship repair according to an embodiment of the present invention is preferably used for repairing small and medium-sized vessel.

On the other hand, when the ship is not repaired, the ship dock for repair of the present invention may be utilized for fishing. That is, by moving to the expected location where the meat is gathered, the opening and closing device 170 of both vertical parts 112 are synchronously operated to lift the gate 160 to open the gate 160, and then to the seawater storage spaces S1 and S2. After opening the valve so that the seawater flows in, the weight of the dock body 110 is increased by seawater to maintain the dock body 110 in a submerged state for a predetermined time (as shown in FIG. 7), and then the opening and closing device 170 is opened. When operated and the gate 160 is lowered and closed (shown in FIG. 4), the seawater may be confined including meat in the ship receiving space S3.

Therefore, it is possible to easily catch the meat trapped in the ship receiving space (S3), it can be utilized as a fishing place as needed.

Moreover, in the floating dock for ship repairs which concerns on this invention, the gate 160 adheres to the guide member 115 which consists of rubber materials, and its watertightness is high. Therefore, since seawater does not flow into the ship accommodation space (S3) at the time of sailing or ship repair, it is possible to facilitate sailing and ship repair. Then, after confining the seawater in the vessel receiving space (S3), the seawater in the seawater storage spaces (S1, S2) of the dock body 110 by pumping and emptying the dock body 110 even in the vessel receiving space (S3) Since the confined seawater does not fall out, the confined seawater can be used for various purposes.
