As the international phenomenon of industrialization and industry develops, the use of resources such as petroleum is gradually increasing, and thus the stable production and supply of oil is becoming a very important issue on a global scale.

For this reason, the development of the marginal field or deep-sea oil field, which had been neglected due to economic difficulties, has become economic in recent years.

Therefore, along with the development of submarine mining technology, marine structures suitable for the development of these oil fields have been developed.

Various types of offshore structures have been developed. Manifolds have been developed to collect crude oil or gas collected from the sea floor and supply it to offshore production platforms or offshore plants.

As shown in Fig. 1, a suction file 10 is fixed to a seabed, and a manifold 20 is provided on a suction file 10.

At this time, a plurality of collection pipes 21 are installed in the manifold 20, and the collection pipe 21 is connected to the well point of the seabed so as to supply raw oil or gas collected from the oil well to the manifold 20, Lt; / RTI >

The crude oil or gas collected from the collection pipe 21 is supplied to the offshore production platform or the onshore plant through the delivery pipe 22 through the control of each valve provided on the manifold 20.

On the other hand, leveling of the manifold 20 installed on the suction pads 10 is very important, and leveling should be performed within an error range of 2 degrees based on the suction pads 10.

For this purpose, as shown in FIG. 2, a shim plate 30 having a height different from that of the foundation 11 at some points of the foundation 11 for installing the manifold 20 on the suction file 10 And the leveling operation of the manifold 20 was performed using the height and the position of the simplex 30.

However, since the leveling operation of the manifold 20 through such simple rate operation 30 is difficult to perform the leveling operation in detail, the accuracy of the leveling is low and the efficiency of the leveling operation is inferior due to repeated operation several times .

That is, an additional process for leveling the manifold 20 occurs, resulting in a problem that the productivity of the work is low.

The manifold for this purpose will be described with reference to FIGS. 3 and 4 attached hereto.

The manifold 20 collects the raw oil or gas collected from the oil wells of the seabed and feeds them to the offshore or onshore plant, and is integrally fixed on the suction pod 10.

A suction pile 10 is a base material for installing the manifold 20 on the seabed and is formed in a cylindrical shape.

The suction puff 10 is formed of a cylindrical pipe member having a hollow portion, that is, the bottom portion of the suction puff, that is, the lower end portion of the suction puff is opened and the upper end of the hollow puff, that is, the suction puff 10 is closed by the finishing plate 10a .

The suction pads 10 are provided in plural as shown in Figs. 3 and 4, and are preferably provided in a total of four, one at each corner of the bottom surface of the manifold 20.

At this time, the number of the suction pads 10 is not limited, and may be further provided along the bottom surface of the manifold 20.

Suction pump sockets 30 are provided on the finishing plate 10a of each of the suction pads 10, respectively.

The suction pump socket 30 is connected to an ROV to be described later, and the suction operation of each suction pawl 10 is performed by the ROV.
