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 seabed mining technology, drilling rigs with drilling facilities suitable for the development of such oilfields have been developed.

In recent years, the development of deep-sea oil fields has been actively promoted, so safety of various drilling equipments is especially important. Among the drilling equipments, the most relevant equipment for drilling is BOP (Blow out Preventer, Prevention device).

BOP equipment is installed to prevent the gas explosion of submarine wells by safely removing high pressure gas generated during drilling process and connected to the upper wellhead of submarine oil well through a riser from marine drilling facility .

These BOP equipment is designed to withstand a pressure of 15,000 psi with internal pressure in a high pressure (4,300 psi) environment at depths of 3,000 m or more, suitable for deep sea environments. However, since the test is not performed in the actual environment until it is installed in the actual deep water well, various problems arise in actual installation work.

Generally, the test for the BOP equipment is partially tested by applying external pressure or internal pressure separately to each part constituting the BOP equipment, and there is no device capable of performing such a test in the fully assembled state As a state, there is a desperate need for a device capable of performing various types of testing under the same conditions as the actual environment.

At this time, a plurality of pressure vessels 100 are provided and connected to the external pressure supply unit 400, so that a plurality of test equipment can be simultaneously tested.

First, the individual test methods and structures for the test target equipment are examined through the respective pressure vessels 100.

The test chamber C is formed in the inner space of the pressure vessel 100 so that the equipment to be tested can be inserted therein. The liquid is stored in the test chamber C so that the equipment to be tested is locked. In this case, the equipment to be tested may be a device used in a deep sea environment, for example, a BOP equipment 200 that is latched to the upper well head of a seabed well to prevent internal gas explosion of the seabed well can be applied . Hereinafter, for convenience of explanation, the case where the BOP equipment 200 is applied as the equipment to be tested will be described as an example.

The pressure vessel 100 may be formed in the form of a container having various shapes in which a test chamber C is formed. It is preferable that the pressure vessel 100 is formed in a cylindrical shape in consideration of the supporting strength against the internal pressure of the pressure vessel 100 . In addition, the pressure vessel 100 may be configured in such a manner that it is connected to a negative electrode power source for corrosion prevention.

2, the pressure vessel 100 includes a container body 110 having a part of an upper surface thereof opened so as to form a test chamber C in an inner space thereof, And can be separately formed by the container cover 120 to be coupled. The liquid L can be stored in the test chamber C of the container body 110 with the container cover 120 opened through such a structure and the liquid L can be stored in the test chamber C of the BOP equipment 200 may be charged into the test chamber C so as to be immersed in the liquid L. The container body 110 may be provided with an external pressure supply port 111 and an internal pressure supply port 112 so as to be supplied with pressure from an external pressure supply unit 400 and an internal pressure supply unit 500 to be described later. The container body 110 and the container cover 120 may be sealed to each other so that the liquid L stored in the internal test chamber C can be maintained at a high pressure state through the pressure supply by the external pressure supply unit 400 .

The external pressure supply unit 400 is configured to raise the pressure of the liquid so that the pressure of the liquid stored in the test chamber C of the pressure vessel 100 reaches a pressure under a severe condition, for example, 4,300 psi or more.

The external pressure supply unit 400 includes an external pressure supply pump 410 which operates to supply fluid to the test chamber C of the pressure vessel 100 at a high pressure and a high pressure fluid which is supplied from the external pressure supply pump 410 to the test chamber C And an external pressure connection line 420 connecting the external pressure supply pump 410 and the test chamber C to be supplied to the test chamber C.

[ The test well head 300 is the same as the wellhead coupled to the top of the subsea well and is fixedly mounted within the pressure vessel 100 for testing of the BOP equipment 200 in one embodiment of the present invention. Accordingly, the BOP equipment 200 and the test well head 300 are coupled to each other so that the internal spaces are communicated with each other in a state where the BOP equipment 200 and the test well head 300 are latched to each other.

In this case, it is preferable to further include an internal pressure supply unit 500 for supplying a high-pressure fluid to the test well head 300 so that internal pressure is transmitted to the BOP equipment 200 through the test well head 300. The pressure-resistant supply unit 500 is configured to supply high-pressure fluid so that the internal pressure of the BOP equipment 200 is so high that a pressure occurring when a gas explosion occurs in the oil well, for example, a pressure of 15,000 psi or more.

The pressure-resistant supply unit 500 includes an internal pressure supply pump 510 that operates to supply a high-pressure fluid to the test well head 300 and an internal pressure supply pump 510 that supplies high-pressure fluid from the internal pressure supply pump 510 to the test chamber C And an internal pressure connection line 520 connecting the internal pressure supply pump 510 and the test well head 300. The pressure-resistant supply pump 510 may be applied in the form of a pump for supplying liquid, or may be applied in the form of a multi-phase pump capable of simultaneously supplying liquid and gas to reproduce the gas generating situation in the oil well have. The pressure-resistant connection line 520 may be configured to be connected to the pressure-resistant supply port 112 of the container body 110.

According to such a configuration, the drilling equipment testing apparatus according to one embodiment of the present invention raises the pressure of the liquid inside the pressure vessel 100 to the deep sea pressure state of 3,000 m or more by the external pressure supply unit 400, An external pressure test for the equipment 200 can be performed. That is, when the BOP equipment 200 is exposed to deep pressure, it can be tested whether it is structurally stable, whether it operates normally, or whether leaks occur.

Also, by providing the BOP equipment 200 with an internal pressure of 15,000 psi or more through the pressure-resistant supply unit 500, it is possible to perform the pressure resistance test of the deep-sea environment for the BOP equipment 200. [ For example, it is possible to perform an internal pressure test on Ram, Annular, and various valves constituting the BOP equipment 200.

First, the liquid is stored in the test chamber C formed in the container body 110 of the pressure vessel 100. The test chamber C is provided in the container body 110 of the pressure vessel 100.

At this time, the BOP equipment 200 may be mounted on the lower end of the container cover 120 so as to be inserted into the test chamber C at the same time during the sealing process of the container cover 120. That is to say, by coupling the container cover 120 and the BOP equipment 200 together so that the container cover 120 is coupled to the upper surface of the container body 110 by the crane, May be configured to be injected into the test chamber (C). At this time, the BOP equipment 200 is put into the test chamber C, and at the same time, it is fit to the test well head 300 located under the inner space of the container body 110. Therefore, the operation of closing the container cover 120 to the container body 110 can be performed simultaneously with the closing operation of the BOP equipment 200 and the operation with the test well head 300. This simplifies the operation and can be performed conveniently and quickly.

In this case, in order to guide the vertical movement path of the BOP equipment 200 in the process of putting the BOP equipment 200 together with the container cover 120 into the inner space of the pressure vessel 100, A separate movement guide (not shown) may be mounted in the inner space.

That is, the power and valve operation signals are transmitted through the mux cable, and the operations of closing and opening are performed using the supplied hydraulic pressure of the ram and the annulus of the BOP equipment. In other words, the control room can be operated by controlling the BOP equipment by connecting the BOP equipment with the hydraulic cable for supplying the control command and the hydraulic cable to the hydraulic cable.

According to this structure, it is possible to test whether or not the installation process of the BOP equipment 200 is normally performed in addition to the external pressure and internal pressure test for the BOP equipment 200. For example, it may be tested whether the BOP equipment 200 normally latches into the test well head 300. [ In addition, various control tests for the BOP equipment 200 and tests for all operations occurring in the actual seabed well are performed through the control room, which performs the same function as the BOP control system in the drilling facility and can control the operation of the BOP equipment 200 It is possible.

Various sensors and image devices may be further installed inside the pressure vessel 100 to monitor the internal state of the pressure vessel 100 and the operation state of the BOP equipment 200. In addition, The devices can be connected to the control room to monitor the operation status of the BOP equipment 200 through the control room.

The sensor module 140 may include a pressure sensor, a temperature sensor, a strain gauge, a level meter, and the like. The deformation amount of the BOP apparatus 200 with respect to the ram apparatus can be measured through the strain gauge and the environmental conditions such as the pressure and temperature with respect to the internal space of the pressure vessel 100 can be measured through the pressure sensor and the temperature sensor . Also, it is possible to observe the latching process of the BOP equipment and the test well head through the underwater camera 150, and confirm whether the equipment is broken or not.

2, an acoustic control unit 160 for transmitting and receiving information to / from the control room 600 may be mounted in the pressure vessel 100. The acoustic control unit 160 may include an acoustic control command unit, a transducer, And a transceiver. It is possible to perform the operation control function of the BOP equipment through the acoustic control command unit and to receive the BOP equipment control information and transmit the monitoring information through the transducer and the transceiver.

Meanwhile, a separate robot arm 700 may be mounted in the pressure vessel 100 so as to perform a test auxiliary operation on the BOP equipment 200 fixedly mounted in the test chamber C. The robot arm 700 can be manufactured in various forms, and a robot arm used in a general ROV (Remotely Operated Vehicle) can be applied. The robot arm 700 may be configured to assist a coupling process between the BOP equipment 200 and the test well head 300 or perform various operations such as an operation test function, a pressure test assist function, and a maintenance function for the BOP equipment And the operation control for this can be performed through the control room.

However, in addition to the BOP equipment 200, various drilling equipment used in a deep sea environment such as a Christmas tree can be applied. You will also be able to perform integrated operation tests, including transport and mud circulation tests and Christmas tree equipment tests. Here, the integrated operation test may include all the system operations from departure to mission return to return. In addition, the equipment under test can be applied to all types of equipment working or installed in the deep sea as well as drilling equipment, and external pressure test and pressure test can be applied to them.

As described above, various tests such as an external pressure test and an internal pressure test can be performed on the BOP equipment 200 by putting the BOP equipment 200 in the test chamber C of each pressure vessel 100, And a plurality of pressure vessels 100 are connected to one external pressure supply unit 400 as shown in FIG. 1, so that a plurality of BOP equipment 200 can be simultaneously tested. Also, a plurality of pressure vessels 100 may be connected to one pressure-resistant supply unit 500 so that an internal pressure test for the BOP equipment 200 may be performed simultaneously for a plurality of BOP equipment 200. [

The external pressure supply unit 400 may simultaneously supply pressures to the test chambers C of the plurality of pressure vessels 100 and may supply pressures of the same size or different sizes to each of the test chambers C . Similarly, the pressure-resistant supply unit 500 can simultaneously supply pressures to the test well heads 300 mounted on the plurality of pressure vessels 100, respectively. In each of the test well heads, pressure equal to or different from each other As shown in FIG.

1, the external pressure supply unit 400 includes a plurality of external pressure supply pumps 410 and a plurality of external pressure supply pumps 410, And an external pressure connection line 420 connecting the external pressure supply pump 410 and the pressure vessel 100 so as to be delivered to the test chamber C, respectively.

The external pressure connection line 420 includes an external pressure main line 421 and an external pressure pump line 422 branched from one end section of the external pressure main line 421 and connected to the plurality of external pressure supply pumps 410, And a plurality of external pressure vessel lines 423 branching from the other end section of the external pressure main line 421 and connected to the plurality of pressure vessels 100, respectively. In this case, an external pressure sub opening / closing valve 425 may be mounted on the external pressure vessel line 423, respectively. The external pressure main line 421 may be equipped with a separate external pressure main opening / closing valve 424 between the positions where the external pressure pump line 422 and the external pressure vessel line 423 are branched.
