In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

First, referring to FIGS. 1 to 3, an apparatus for installing a condenser and a positive riser system according to an embodiment of the present invention will be described.

1 to 3, an apparatus for installing a concentrator and a positive riser system according to an embodiment of the present invention includes a derrick system 101, a deck crane 102, a spider and gimbals 103, a guideline 105, And a flexible hose reel (104).

The deck crane 102 moves the concentrator 201 to the surface of the water. The concentrator 201 is a robot for collecting submarine mineral from the bottom of the seabed.

The guideline 105 is connected at one end to the flexible hose 202 and at the other end to the water condenser 201 through the doorpost.

The Derrick system 101 is a hosting device for installing a positive riser system. The positive riser system includes a flexible hose 202, a buffer system 203 and a positive riser 204.

The buffer system 203 is a device for lifting the undersea minerals collected in the concentrator 201 to a light beam, which is composed of a crushing device and a pump system. As the collected seabed mineral is large, it is difficult to raise it to the ray, so the crushing device crushes the collected seabed mineral, and the pump system pushes the crushed submarine mineral into the mining line.

The flexible hose 202 is attached to the top of the concentrator 201 to connect the concentrator 201 and the buffer system 203. A buoyancy material may be attached to the flexible hose 202 for smooth movement of the condenser 201. In other words, the condenser 201 can smoothly move as the buoyant material sustains the weight of the flexible hose 202.

The positive riser 204 is a pipe made of steel which serves as a main transfer passage for deep-sea mineral resources. A buoyancy material may be attached to the positive photoreceiver 204 to support the weight of the positive photoreceiver 204.

The Derrick system 101 includes crown blocks, and the crown blocks serve to pick up and drop the buffer system 203 and the positive riser 204.

The spider and gimbal 103 hold the flexible hose 202 while connecting the flexible hose 202 and the buffer system 203 and hold the flexible hose 202 while connecting the buffer system 203 and the light riser 204 ).

That is, when connecting the flexible hose 202 and the buffer system 203, when the spider and the gimbals 103 hold the flexible hose 202, the crown block descends the buffer system 203 and is positioned above the flexible hose 202 . The crown block holds the buffer system 203 while the flexible hose 202 and the buffer system 203 are connected to each other through a connection device. When the connection between the flexible hose 202 and the buffer system 203 is completed, the crown block is lowered to the buffer system 203.

When the spider and gimbal 103 hold the buffer system 203 when the buffer system 203 and the positive photomultiplier 204 are connected to each other, the crown block descends the positive photomultiplier 204 and is positioned above the buffer system 203 . The crown block is holding the positive light riser 204 while the buffer system 203 and the positive light riser 204 are connected to each other through a connection device. When the connection between the buffer system 203 and the positive photoreceiver 204 is completed, the positive photoreceiver 204 is lowered to the crown block.

The flexible hose reel 104 is a drum-shaped reel in which the flexible hose 202 is wound.

Next, referring to Figs. 1 to 4, a method of installing a condenser and a positive photoreceiving system according to an embodiment of the present invention will be described. FIG. 1 is a view showing first to third steps of a method of installing a condenser and a positive riser system according to an embodiment of the present invention. FIG. 2 is a schematic view of a condenser and a method of installing a positive riser system according to an embodiment of the present invention, FIG. 3 is a view illustrating seventh through ninth steps of a method for installing a condenser and a positive riser system according to an embodiment of the present invention, and FIG. 4 is a cross- Fig. 7 is a view showing a method of installing a riser system.

Referring to FIG. 4, first, a guide line 105 is installed (S410).

1, the flexible hose 202 is wound around the flexible hose reel 104, and one end of the guide line 105 is connected to the flexible hose 202. In the first step shown in Fig. The other end of the guide line 105 is provided with a buoyant member so that the other end of the guide line 105 floats over the surface of the water through the door frame.

Then, the condenser 201 is moved to the water surface by the deck crane 102 as in the second step of FIG. 1 (S420). Then, the guide line 105 and the condenser 201 are connected to each other as in the third step of FIG. 1 (S430).

Then, as in the fourth step of FIG. 2, after the condenser 201 is positioned at the bottom of the door, the condenser 201 is connected to one end of the flexible hose 202 (S440).

Then, as in the fifth step of FIG. 2, the flexible hose 202 is lowered (S450). 2, the other end of the flexible hose 202 is connected to the buffer system 203 and the positive light riser 204 is connected to the buffer system 203 (S460).

When the spider and the gimbals 103 hold the flexible hose 202, the crown block descends the buffer system 203 and moves to the flexible hose 202. At this time, . The crown block holds the buffer system 203 while the flexible hose 202 and the buffer system 203 are connected to each other through a connection device. When the connection between the flexible hose 202 and the buffer system 203 is completed, the crown block is lowered to the buffer system 203.

The crown block is holding the positive light riser 204 while the buffer system 203 and the positive light riser 204 are connected to each other through a connection device. When the connection between the buffer system 203 and the positive photoreceiver 204 is completed, the positive photoreceiver 204 is lowered to the crown block.

Then, the positive light riser is continuously connected (S470).

The positive photoreceiver 204 is constructed by connecting a plurality of positive photoreceiver strings. That is, after connecting the first positive riser string with the buffer system 203, if the crown block lowers the first positive riser string and the spider and gimbals 103 hold the first positive riser string, Place the second positive riser string down on the top of the first positive riser string, and connect the first positive riser string to the second positive riser string. The condenser 201, the flexible hose 202, the buffer system 203 and the positive riser 204 descend to the seabed, while connecting the plurality of positive riser strings in the same manner.

3, the condenser 201 is mounted on the seabed, and the positive light riser 204 is installed while moving the light beam (S480). This is to prevent an excessive bending moment that may occur in the flexible hose 202. [ That is, since the condenser 201 collects the seabed mineral while moving the sea floor, the condenser 201 is provided with an extra portion of the flexible hose 202 that can move.

3, a telescopic joint and a flex joint 205 are connected to the upper part of the positive photoreceiver 204 (S490).

The telescopic joint is a device that compensates the vertical motion of the positive riser 204, and the flex joint is a device that compensates the rotation of the positive riser 204.

The flexible joint is installed in the deck, and the telescopic joint is installed in the flexible joint.
