Abstract

PURPOSE: A pile for the foundation of a plant on a deep seafloor having a posture maintaining function is provided to enable the effective installation of plant equipment installed on the top end of the pile using a posture maintaining blade and shaft. CONSTITUTION: A pile for the foundation of a plant on a deep seafloor having a posture maintaining function comprises a hollow pile, a posture maintaining blade, and a posture maintaining shaft. The bottom surface of the hollow pile is opened. The posture maintaining blade is formed in the inner bottom of the hollow pile in a cross shape and has an underwater camera and an underwater pump. The bottom of the posture maintaining shaft is set, and the top is protruded from the top end of the hollow pile.

Description

Posture Type Deep Sea Plant Foundation File {PILE FOR DEEP SEA}

The present invention relates to a post-maintaining deep seabed plant foundation pile, and in detail, the pile is installed on the deep sea bed is installed in the deep seabed plant on the top to prevent the phenomenon that the file is installed inclined when installed on the deep sea ground It is about the posture maintenance type deep-sea plant foundation pile which can be done.

To collect crude oil buried in deep seabeds, oil wells must be installed at the bottom of the deep sea floor.

These oil wells are installed in the deep seabed of about 1km, so in order to excavate the deep seawater and extract the crude oil into the water, the most important thing is the plant equipment equipped with the pressure pump.

That is, a plant facility for forcibly transporting the mined crude oil to the water phase is necessary.

Such plant facilities are installed by installing the deep sea bottom piles by fixing the plant facilities on top of a separate deep sea bottom pile near the well as shown in FIG. 1.

Such a deep sea pile is usually used as a suction file as shown in Figure 2, such a suction file is to use a cylindrical steel pipe pile with an open lower surface.

That is, while the cylindrical steel pipe pile having the lower surface is in close contact with the bottom of the deep sea bottom, the internal pressure of the cylindrical steel pipe pile having the lower surface is reduced through suction so that the cylindrical steel pipe pile with the lower surface opened by the hydraulic pressure is pressed into the bottom of the deep sea bottom. The method is used.

However, at this time, the cylindrical steel pipe pile having the lower surface is a hollow state and difficult to maintain the posture, otherwise difficult to maintain the posture in the process of being pressed to the bottom of the deep sea, there is a problem,

If divers and submersibles are not available for such posture maintenance, it is very difficult to solve this problem, and if the lower surface does not maintain the posture of the open cylindrical steel pipe pile, there is a problem in setting and operating the plant equipment.

In the prior art, the deep sea-based plant piles have three structures formed in one structure, as shown in FIG. 1, so that when one pile is inclined, another pile may be adjusted such as a suction adjustment. The air and economics that followed were inevitably a problem.

Accordingly, the present invention provides a posture maintenance type deep seabed plant foundation file that can maintain posture even in the deep sea, does not cause problems in the setting and operation of the plant equipment solves the problem of providing a posture-type deep seabed plant foundation file that can be mined by an effective oil well The technical problem to be made.

The present invention to solve the construction problems of the conventional deep seabed plant piles

Deep seabed plant piles according to the present invention is a hollow pile and the lower surface is open,

A posture maintenance blade formed in a cross shape in the lower portion of the hollow pile;

It is to provide a posture-maintaining deep seabed plant foundation pile including a posture maintenance axis that is set by the posture maintenance shaft and the top is installed so as to protrude on the top of the hollow pile.

That is, unlike the conventional deep-sea plant foundation pile, it is possible to maintain the posture by installing the posture holding blade and the posture holding shaft therein, which is possible by using the underwater camera and the underwater pump.

Therefore, the present invention can be installed in the deep seabed plant foundation file using the posture maintaining blade and the axis of the present invention even if difficult to maintain the posture in the deep sea bed is difficult to control the installation of the deep seabed plant foundation file, through which is installed on top of the file Effective installation of the plant equipment becomes possible.

1 and 2 is a photo of the deep sea bed plant foundation files and deep sea bed plant foundation files conventional installations,
3 is a perspective view of a deep seabed plant foundation pile according to the present invention.

To this end, the present invention includes a configuration for maintaining posture in the posture maintenance type deep-sea plant foundation file as shown in FIG.

That is, as shown in FIG. 3, the posture maintaining blade is installed in a cross shape on the lower inner side surface of the pile for deep seabed plant foundation having an open bottom surface.

These blades are to be formed in the form of a vertical plate so as not to interfere with the deep-sea plant foundation pile indentation.

The posture maintaining blade is formed to have a cross shape so as to basically play a role of preventing deformation, such as when the pile for the deep sea plant foundation.

At the central intersection of the posture holding blades, a posture maintaining shaft in the form of a pipe is installed.

In other words, while the blade is penetrated through the lower end of the posture maintenance shaft, the top of the posture maintenance shaft extends to the upper surface of the deep seabed plant foundation pile to protrude.

The posture maintenance axis is equipped with an underwater camera and an underwater pump.

To this end, the submersible pump allows the seawater to be injected at high pressure into the pile through the groove formed in the posture maintenance shaft.

Underwater cameras are also equipped with camera connection lines to identify the inside of the file from the outside.

Therefore, in the water vessel near the oil well, when the pile for deep-sea plant foundation is pushed into the bottom of the sea by suction, if the posture is tilted by the underwater camera, the underwater pump is operated to maintain the posture by operating the underwater pump. It will weaken the deep sea bed that interferes with it.

Through this, the subsea plant foundation pile can remove the obstacles to posture maintenance by hardened subsea ground.

Therefore, when the deep seabed plant piles are continuously indented into the deep sea bed, the posture maintaining shaft is pressed together into the deep sea bed so that the deep seabed plant foundation piles are pressed into the deep sea bed based on the posture maintaining axis.

Claims (2)
