[Detailed description of the invention]

The present invention connects a plurality of hydrocarbon production wells to fluid pipes to store hydrocarbons. I! to the submarine production equipment sent to the i stage! Q, especially for i#i benthic sites (
The present invention relates to a method of providing horizontal support areas. Current oil production is 2,500 feet (762 m >
It extends offshore to a depth of g, at /υ. Regarding undersea minibirth (

[, 1 Typically, a balance 1 is placed on a plurality of piles 1-, which are leveled by adjusting the height of each pile, and fixed on each pile.
It is supported by No. 1- (frame plate) 5. The manifold body also consists of several compartments (1+ay>), most of which are used as connections to the wells ('). One or two compartments may contain liquid or gaseous It is used as a connection to a fluid pipe bundle that transports hydrocarbons to a remote location.The concrete pile on which the concrete pile is placed is
It is usually manufactured commercially and costs several hundred feet. This bar is attached to an underwater hammer.

, (itn), the concrete pile must be adjusted so that the error at both ends along the diameter of the rail is within 3 inches (7, GcJ). Recognize the 7nri of cutting method 61
After 2 hours, if Umbrae 1 is tilted 5 degrees from the horizontal plane, from its - side to the other side, [, L2 (-1-
(0.6 m) or less is a deviation that will be reflected in the actual work. As the depth increases to 2,500 feet (762 m), the problem of horizontally arranging the umbrae 1 becomes greater, and the problem becomes even greater when supporting with a plurality of piles at the bottom. Therefore, the present invention detects the slope of a seabed production site, manufactures a commercially available wedge whose slope is equal to and opposite to the detected slope, and places the wedge at the seabed production site. The method involves the establishment of an underwater support area at a production site on the ocean floor, which consists of steps. Examples of the present invention will be explained below. Referring to FIG. 1, the single pile support is shown resting on the upper pile 12 and a ring-shaped girder 14 attached to each. The broken line represents the distance deviation state that always occurs unless the upper pile 12 is set completely vertically (=J tJ), and is a single pile 12Δ and a ring-shaped girder 14Δ.The middle pile 12 is a normally used support material. However, in the preferred embodiment, the promotion is 6 feet l-(1,8
A 2 inch (5.1 cm) thick Sudir tube is used. This - wooden support pile 12 is 3 (1

It has been taken over by A-B and F-12 in a similar way. A ring-shaped sword 14G in a single pile 12 and - is inserted with an underwater hammer and placed at a depth of 2500 feet (7 (i2 m)) under the sea.The pile 1 Vertical of the wire 11 (tolerance of C for J is CO~ in all directions; In order to be suitable for subsequent work, it is placed in water within a range of 1/2 degree from the horizontal plane. The first application No. 2,114,188 of Fukukoku Tokumu '1 has a d3C.
1)) A ring-shaped body 14 with a diameter of 25 feet (7,6 IT+) is protruded and fixed to the mud. Due to the above-mentioned inclination of 5 degrees, the deviation of both ends of the base of the gutter of 25 feet 1 - (7,6 m) will be 25 feet 1 - (7,6 m) 1142,
In this (this 3.j), Ten Bray 1 ~ is 25 feet (7, On) at the time of setting, and both ends are healed to 100 feet.
It must be placed horizontally within ±2.62 inches (G, 65 cm). J on a large slope? Drilling, drilling, and connecting 31 holes requires a lot of manpower, time, and money since the depth is deep enough to operate the platform Δ-me. Going horizontally by climbing Tenbrei 1 is Aburatsuki Pit 1.”
and production fluid piping connections are essential to the reliable and efficient operation of subsea production equipment. Next, referring to FIG. 2 and FIG.

Because 40 angles are added by 1 compensation IC, C will be adjusted on site.
There is C. Tsushiha (There is no need to center accurately, but
It is necessary to face the required direction -C with respect to the single pile 12. This is accomplished by the orientation pin 30 (FIG. 3) on the T-huff 0. , 180° h position 6? ;
Even if there is a difference, the resulting error from the horizontal plane is no more than 10 degrees, so it is necessary to accurately set the direction [, L' (not an electric number. Therefore, there is a direction error of several degrees). U 'b, the resulting horizontal error is small. Therefore, the submarine buran 1-bom does not need to have a leveling mechanism since the foundation is leveled at 1. A 4f bearing area is also obtained. The direction of the undersea platform can be changed by following the Tenbrei 1 stream.''-Ha20
This is possible as long as it is not affected. Rashi complement (nuko,

During operation, at J3, the displacement of the middle pile 12 (see FIG. 1) is measured and the inclination of the ring-shaped mander is determined. The wafer 20 is pre-prepared to compensate for the detected inclination of the wafer 14. The wafer 20 is held up on the holding pin 28 and 1 is lowered to the soil in the ring-shaped girder 14 on the single pile 12 by the method currently used as a funnel. Place the center groove 1-32 to the right to form the center groove 1-32.

If recognized. When the single pile 12 is used as the only support for the unbraided pile 1~, a further problem arises in securing the unbraided 1~ to the single pile 12. Therefore, the single note must be firmly fixed to the upper pile 12 at 1 ITF even if the single pile 12 deviates from the vertical. However, the central axis of the tensile system 1 to 40 is always substantially perpendicular, and when the central axis of the single pile 12 is deviated from the vertical direction, the central axis of the single pile system 12 forms an angle with it. - is at the horizontal position n. Next, referring to FIGS. 4 to 7, the temples 1 to 40 are connected to the gimbal f=J ring 42 via the universal connection part 44, and the gimbal f=J ring 42 is connected to the gimbal f=J ring 42 through the universal connection part 48. The fluid actuated slip latch 46 is shown as being removed from N1. Fluid actuated slip ring launch 46 includes; 1.
