< Resolution of  Usage pattern>

Next, referring to FIGS. 2 to 8, the use of the resolution unit according to the present invention will be described in detail.

Here, FIG. 2 is a view showing a state in which the structure is dried using the resolution according to the present invention.

FIG. 3 is a view showing a state in which the dock module according to the present invention is lifted up, FIG. 4 is a view showing a state in which a floating structure capable of floating on the sea is launched using the resolution according to the present invention, 5 is a view showing a state in which the structure of FIG. 4 is fed.

6 is a view showing a state in which a structure having a high resolution according to the present invention is supported using a cable, FIG. 7 is a view showing a state in which a structure is transferred in FIG. 6, and FIG. And the structure is installed on the FPSO ship by using the claw.

First, as shown in FIG. 2, the resolution according to the present invention can dry the structure C on the dock module 200.

At this time, it may be advantageous that the dock module 200 is disposed over the sea surface SL.

In this case, a marine pant cranes necessary for drying the structure C or a ship or the like supplying various materials can be easily accessed to the side of the dock module 200.

Also, in this state, it may be advantageous for the dock module 200 to have at least a portion of the tank inside the ballast portion to have a predetermined buoyancy.

In this case, the load applied to the supporting module 100 by the weight of the dock module 200 and the structure C can be reduced.

Meanwhile, as shown in FIG. 3, the resolution according to the present invention can lift the dock module 200 to the upper part of the sea level SL.

When the wind speed at the position where the resolution cube according to the present invention is worsened and the wind speed and wave height are increased, the resolution state is deteriorated and the dock module 200 is difficult to be stably fixed, C may also be difficult to be stably mounted on the upper portion of the dock module 200.

In this case, the dock module 200 can be lifted higher than the sea level SL through the driving module 300 because the resolution according to the present invention is damaged or the risk of a safety accident increases.

The dock module 200 can move upward so as to be separated from the sea level SL because the support module 100 protrudes to the upper portion of the sea level SL relatively longer than the thickness of the dock module 200. [

Through this process, the dock module 200 and the structure C on the dock module 200 can be relatively stable regardless of the state of the water.

At this time, it may be advantageous to relatively reduce the weight of the dock module 200 itself by discharging all the seawater in the ballast portion.

Meanwhile, as shown in FIG. 4, the resolution according to the present invention can move the dock module 200 downward to launch the dried structure C.

In this case, the structure C to be dried may be a structure C that can float on the sea.

The dock module 200 moves down to the seabed according to the driving of the driving module 300 and the structure C supported by the dock module 200 can float on the sea through its own buoyancy.

At this time, the dock module 200 may be filled with seawater in the ballast portion, and it may be advantageous to minimize the buoyancy of the dock module 200 itself.

When the structure C launched in the above manner is movable, the structure C can be transferred using the power of the structure C itself.

On the other hand, when the structure C can not move by itself, the structure C can be transferred using a separate transportation line T as shown in FIG.

In this case, it may be advantageous for the dock module 200 to move the dock module 200 to the seabed so that the distance between the lower surface of the floating structure C and the upper surface of the dock module 200 becomes longer than the thickness of the transportation line T have.

At this time, a transportation line T such as a general launch dock can be disposed below the structure C, and the structure C can be lifted and transported through the transportation line T.

Meanwhile, as shown in FIG. 6, the resolution according to the present invention can support the structure C using the cable 500.

First, the structure C to be dried at the upper portion of the dock module 200 and the auxiliary supporting module 400 provided at the upper portion of the structure C may be interconnected by the cable 500.

At this time, the process of connecting the structure C and the auxiliary supporting module 400 with the cable 500 may be easily performed by moving the dock module 200 upward.

In addition, the position of the cable 500 may be moved and fixed along the auxiliary supporting module 400 to effectively fix the structure C according to the shape and the center of gravity of the structure C.

Then, when the connection of the structure C and the auxiliary supporting module 400 is completed, the dock module 200 can be moved down to the submarine space.

The structure C supported on the upper portion of the dock module 200 is supported by the auxiliary supporting module 400 through the cable 500 so that the structures C and The distance between the dock modules 200 can be increased.

That is, the structure C can be held floating in the space above the sea surface SL while maintaining the marginal state of the auxiliary supporting module 400.

7, a separate transportation line T for transporting the structure C can be disposed at the lower portion of the structure C. As shown in Fig.

At this time, the transportation line is moved upward by adjusting the draft of the transportation line T or the structure C is moved downward by adjusting the length of the cable 500 to be long through the winch unit 510, And the transportation line T can be brought into contact with each other.

With this method, the structure C can be supported using the transportation line T, and the structure C can be transported to a desired location.

It may also be advantageous to transfer through such a method if the structure C to be dried is a structure C that can not float on the sea.

The above-described drying and conveying method (C) of the structure (C) may be particularly advantageous for drying and conveying the structure (C) having a very large weight and size.

As shown in FIG. 8, the hull such as Floating Production Storage Offloading (FPSO) has a very large weight and size of the upper structure. In this case, too, (C) can be dried and installed in the floating oil production storage / unloading facility (F).

The dried structure C is fixed to the auxiliary supporting module 400 via the cable 500 and the dock module 200 is moved downward to move the floating structure It is possible to apply the method of directly moving the production storage and unloading facility (F).

By this method, it is possible to facilitate the drying of the upper structure of the floating crude oil production storage / unloading facility F, thereby reducing the construction time and cost.

That is, through the resolution according to the present invention, it is possible to stably perform drying of the structure C even in various marine conditions.

Further, it is possible to obtain an effect of facilitating the movement of the structure C to be transported to a carrier or the like for transportation.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is self-evident to those of ordinary skill in the art. Accordingly, it should be understood that such modifications or alterations should not be understood individually from the technical spirit and viewpoint of the present invention, and that modified embodiments fall within the scope of the claims of the present invention.
