Description

[0002] Connection devices and systems for pipelines [0003]

The present invention relates to pipeline interconnecting devices and systems.

When producing natural gas and oil from the ocean floor, the products from the wells travel through the pipeline. Then, it goes up to a marine platform or a marine storage facility through a riser. Alternatively, they may be connected to other pipelines and delivered directly to the land without going through the maritime platform. On the other hand, the pipeline can move due to shrinkage / expansion and environmental load due to the internal flow of the pipeline at the seabed. Equipment such as a jumper or spool is additionally installed between the subsea equipment to accommodate this. In recent years, the development of deep sea wells has become more and more important, and the installation of such additional equipment leads to an increase in the time required for development of the entire field and an increase in costs. Further, as the water depth becomes deeper, it is difficult to precisely control and install additional equipment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. A description thereof will be omitted.

1 is a conceptual diagram for explaining a connection system according to some embodiments of the present invention.

1, a connection system according to some embodiments of the present invention includes a connection device 100, a riser 12, a pipeline 17, a gooseneck module 15, a flexible riser 16, etc. do.

The pipeline 17 is connected to a well or reservoir distributed on the seabed. The length of the pipeline 17 may be several tens to several hundred kilometers or more.

The riser 12 may extend in the vertical direction, and the material may be steel, but is not limited thereto. The riser 12 can be installed in the vertical direction by the negative electrode 11. The riser 12 may be connected to the flexible riser 16 via a gooseneck module 15. The riser 12 is shown, for example, in the form of a Free Standing Hybrid Riser (FSHR), but is not limited thereto. The flexible riser 16 may be connected to a vessel (e. G., A marine platform, marine storage facility)

The connecting device 100 is installed on the seabed and can deliver the fluid (i.e., gas or oil) provided through the pipeline 17 to the riser 12. In some embodiments of the present invention, such a coupling device 100 is simply installable and can connect pipeline 17 and riser 12 very easily. The connecting device 100 includes a first connecting part 130 connected to the riser 12 and a second connecting part 140 connected to the pipeline 17. Since the first connection part 130 and the second connection part 140 can be tensioned / shrunk, it is possible to connect the connection device 100 more easily when connecting the connection device 100 to the riser 12 and the pipeline 17. Also, the installation of equipment such as jumpers or spools can be omitted.

FIGS. 2 to 4 are views for explaining the connection device of FIG. 2 is a perspective view illustrating a connecting device according to a first embodiment of the present invention.

Referring to FIG. 2, the connection device according to the first embodiment of the present invention includes a base 110 and a connection module 105.

The base 110 is installed on the sea floor. 2, the shape of the base 110 is illustrated as a rectangular parallelepiped, but the present invention is not limited thereto. That is, the base 110 can be any shape as long as it can be fixed to the sea floor.

The connection module 105 is installed in the base 110. The connection module 105 includes a first connection part 130 connected to the riser 12 and a second connection part 140 connected to the pipeline 17 and the first connection part 130 and the second connection part 130 140 can be moved with respect to the hinge 125 (see reference symbol A). Alternatively, the first connection part 130 and the second connection part 140 may be directly connected to the hinge 125, or the 'A' shaped body 160 shown in FIG. 2 may be connected to the hinge 125 And the first connection part 130 and the second connection part 140 may be coupled to the body 160. [

The first connecting part 130, the second connecting part 140, the body 160 and the hinge 125 are connected to the rotating plate 120. The rotating plate 120 is connected to the That is, on the xy plane) (see reference character B). That is, the connection module 105 is rotatable on the base 110.

In particular, the first connection part 130 includes a plurality of first cylinders 131 and 132 that share a central axis and have different inner diameters, and can be stretched or contracted. Likewise, the second connection portion 140 includes a plurality of second cylinders 141 and 142, which share a central axis and have different inner diameters, and are capable of being tensioned or contracted. Although only two first cylinders 131 and 132 and two second cylinders 141 and 142 are shown in the figure for convenience of explanation, the present invention is not limited thereto.

When the first connection part 130 and the second connection part 140 can be tensioned or contracted, the position of the connection device itself is changed according to the distance or position with respect to the riser 12 or the pipeline 17 You do not have to do. Since the hinge 125 and the rotary plate 120 are provided, the first connection part 130 and the second connection part 140 are rotated in any direction of the x-, y-, and z-axes, ) Or pipeline (17). That is, it is possible to maximize the range in which the first connection part 130 and the second connection part 140 can be connected to the riser 12 / pipeline 17, and accordingly, the connection module 105 and the riser 12 / pipeline 17 can be connected.

3 is a perspective view illustrating a connecting device according to a second embodiment of the present invention. For the sake of convenience of description, substantially the same contents as those described with reference to Fig. 2 will be omitted below.

Referring to FIG. 3, the connection module 105 includes a body 160 having a first connection part 130 and a second connection part 140. Particularly, a fluid passage is formed in the body 160. The fluid supplied from the pipeline 17 and the second connection part 140 is transferred to the first connection part 130 and the riser 12 after the body 160 is filled. That is, the body 160 plays an intermediate role as a fluid tank for fluid exchange.

4 is a perspective view illustrating a connecting device according to a third embodiment of the present invention. For convenience of description, substantially the same contents as those described with reference to Figs. 2 and 3 will be omitted below.

4, the base 110 includes a first sliding root 230 to which the first connecting portion 130 can slide, a second sliding root 240 to which the second connecting portion 140 can slide, Respectively. The first sliding root 230 and the second sliding root 240 are spaced apart from each other. As shown in FIG. 4, the first sliding route 230 and the second sliding route 240 may be arranged side by side in 11-letter form. The first connection part 130 and the second connection part 140 can move independently (without interference between each other).

The first connection part 130 can move along the first sliding route 230 and can rotate within the first sliding route 230. Likewise, the second connection portion 140 can move along the second sliding route 240 and rotate within the first sliding route 230. By doing so, the fluid exchange becomes smooth, and the connectable range with the pipeline 17 and the riser 12 can be widened.

The fluid supplied from the pipeline 17 and the second connection part 140 is transferred to the first connection part 130 and the riser 12 after the base 110 is filled. That is, the base 110 plays an intermediate role as a fluid tank for fluid exchange.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
