Description

{A riser Yoke for pipeline}

The present invention relates to an apparatus for transporting pipes for oil and gas drilling in the sea bed.

The amount of resources to be harvested has been increasing due to industrialization and industrial development for a long time, and the dependence of energy resources on the seabed is increasing. As the mining and reliance on the seabed energy resources is increased, drilling workload of drill ship is increasing.

In the case of Korea, exploration is continued in some areas where development is possible since the 1970s. In the western and southern seas of Korea, the continental shelf is developed and oil is likely to be buried. In particular, US oil companies drilling in the south of Jeju Island estimate that at least 600 million barrels of oil will be buried. In addition, private companies in Korea are engaged in oil and natural gas development projects in the sea of Madura in Indonesia and the sea in North Bay.

Drill rigs use a variety of methods to transfer tubular members from a pipe rack adjacent to the bottom of the drill to a small hole or borehole on the bottom of the drill to connect it to a previously transported pipe or tubular string. The term " tubular "or" pipe ", as used herein, refers to any shape of drilling pipe, drill collar, casing, liner, bottom hole assembly: BHA) and other types of tubes known in the art.

Typically, drilling rigs utilize a combination of a drilling crane and a transfer system to transport the pipe from the pipe rack to a vertical position above the wellhead center. A distinct disadvantage of the prior art systems is that it involves significant manual labor in attaching the pipe elevator to the pipe and moving the pipe from the drill rack to the well head rotary table do. These manual movements near the workers are potentially very dangerous and in fact have caused many injuries in drilling. This risk can also be linked to pipe damage, which may affect the integrity of the connection between successive pipe lines in the well.

[0002] A pipe transporting apparatus for transporting a pipe to a low-lying state comprises a supporting structure, a support structure extending from the support structure, An arm capable of moving between a spaced first position and a second position on the lower surface and a stiffening means cooperating with the arm when the arm and the support structure are in the second position To a pipe conveying device for conveying a pipe to a bottom of a slope. The stiffening means applies a mechanical resistance to the arm in the second position. In the 10 < th > -0113607, the second position is the end of the support structure and the progression of the arm. The strengthening means cooperates with one end of the arm on the opposite side of the support structure. The energizing means applies a variable resistance to the arm when the arm moves from the first position to the second position. The variable resistor becomes larger when the arm is in the second position. Gripper means is attached to one end of the arm on the opposite side of the support structure. The gripper means houses a pipe therein. The gripper means supports the pipe in a vertical direction when the support structure and the arm are in the second position. In addition, the gripping means grips the horizontal pipe when the arm and the support structure are in the first position. The support structure has an open interior area. The gripper means is coupled to the arm such that the pipe moves through the open interior region as the support structure and the arm move from the first position to the second position.

In this specification, the terms "comprises" or "having" and the like refer to the presence of stated features, integers, steps, operations, elements, components, or combinations thereof, But do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or combinations thereof.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a pipe conveying apparatus for marine drilling which is attached to a crane and includes a main beam 100 in the longitudinal direction of the pipe to be conveyed and a crane connecting portion 200 installed in the center of the main beam 100, And a pipe grasping part 300 installed at both ends of the main beam 100. The pipe grasping part 300 is installed to move in the longitudinal direction of the main beam 100, (320) which is adjacent to the grip inserting port (310) and which is in contact with the upper surface of the pipe, has a gripping hole (310) inserted into one through hole of the pipe at the lower end of the pipe (300) Provides a pipe conveyor for marine drilling. According to the above construction, the pipe transporting apparatus for ocean drilling according to the present invention is connected to a crane, and grasps and transports the pipe in a horizontal direction. According to the configuration of the present invention, pipes of 16 tons or more can be carried.

The pipe gripping unit 300 includes a tilt cylinder 330 for balancing the gripped pipe and adjusting the position of the pipe contact surface 320 according to the pipe size; And a connection rod 340 connecting the tilt cylinder 330 and the pipe contact surface 320 to move the pipe contact surface 320 up and down according to the contraction and relaxation of the pipe cylinder. The inclination of the pipe inevitably accompanies carrying the pipe as the present invention grasps the pipe in the horizontal direction. Therefore, correction of such slope is essential. A primary correction of this slope is made through the tilt cylinder 330. In addition, it is preferable that the pipe waveguide 300 horizontally moves within a range of 1350 mm to 1800 mm in the longitudinal direction of the main beam 100. This movement of the horizontal movement is intended to allow the insertion port to be easily inserted into the pipe. Unlike the conventional gripping means, the gripping hole 310 of the present invention can be inserted into the pipe in a single operation, thereby maximizing ease of operation. In addition, when the above-mentioned finger-type insertion port is repeatedly applied with a maximum stress of 264.5 MPa to a trolley, the minimum lifetime has a durability of about 9700 cycles.

The crane connecting part 200 includes a damping cylinder 210 connecting the lower part of the crane connecting part 200 and the upper surface of the main beam 100 to balance the gripped pipe, To distribute the eccentric load according to the slope of the eccentric load. Since the crane driver does not easily cope with the above inclination, the damping cylinder 210 may maintain the slope of the pipe horizontally according to the control device according to the information from the gyroscope sensor that senses the inclination of the pipe It is preferable to control the hydraulic pressure in the cylinder.

The upper member 240 of the crane connecting part 200 has a rotating joint so that the pipe can rotate in a horizontal direction, and the rotating joint preferably has a rotating decelerating part for damping excessive rotation of the pipe.

Such a tilt and rotation deceleration are controlled by a control device according to the detection and detection result by the sensor, and such a control interface will be described with reference to an exemplary diagram of the interface of FIG. That is, the present invention provides a technique of mounting an encoder for a sensor signal and catwalking the sensor in a horizontal direction while keeping the direction of the device constant. And can be easily operated by the push button of the control screen through the above interface. According to the control interface, the rotation speed is controlled to 0 to 0.5 rpm, and the inclination is controlled to be 7.5 [deg.].

The inclination and rotation motion of the pipe are controlled through the inclined cylinder 330 of the pipe gripper 300, the damping cylinder 210 and the rotary deceleration unit, and they are configured to be collectively controlled by the integrated hydraulic circuit . That is, the hydraulic pressure on the hydraulic circuit is distributed based on the data collected from the sensor to control the horizontal state of the pipe. This process is performed by a user's simple button or touch screen operation according to the control interface described above.

That is, when the pipe is gripped and lifted, the installed sensor collects mechanical information such as the tilt and the rotational motion of the pipe. The collected mechanical information is processed by the control device to control the movement of the tilt cylinder 330, the damping cylinder 210, and the rotation decelerator to suppress tilt and rotational motion. When the pipe is catwalked in the horizontal direction, the velocity, acceleration and inertia data as the movement is added, and accordingly, the controller collects the information collected from the sensor in real time in order to suppress the movement of the pipe during the catwalk movement And controls the movement of the tilt cylinder 330, the damping cylinder 210, and the rotation deceleration unit.

The crane connecting part 200 has a length adjusting cylinder 220 for adjusting the length and is divided into a lower member 230 and an upper member 240 around the length adjusting cylinder. Preferably, the length of the length adjusting cylinder 220 can be adjusted to be 800 to 1,500 mm at the minimum length, and may have a damping interval of 500 mm. The damping section minimizes the impact of the crane on the weight of the pipe and improves the stability of the work.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.
