Description

Technical Field

[0001] The present application relates to an underwater control module testing device. Background Art

[0002] In recent years, the oil industry has gradually expanded into the ocean, and subsea production systems have become a crucial technology for offshore oil and gas field development. The sophistication of the equipment used in deepwater development is a key factor in determining development success. The subsea control module (SCM) is the core device of the subsea control system, controlling the valves on the subsea Christmas tree, monitoring the tree's status, and providing timely feedback on subsea equipment to offshore equipment. Conventional hydraulic testing equipment typically utilizes a one-to-one single-point connection for piping. This often results in an inefficient one-in, one-out connection for hydraulic piping, requiring frequent and repeated piping removal and installation, significantly impacting equipment life, piping sealing, timeliness, and repeatability.

[0003] Conventional hydraulic test equipment cannot be used for pressure monitoring while providing an external hydraulic pressure test source.

[0004] Conventional hydraulic equipment does not have safety protection devices during hydraulic testing operations. Summary of the Invention

[0005] In view of this, the technical problem to be solved by this application is to provide an underwater control module testing device to solve the problem of difficulty in testing underwater control modules in the technology.

[0006] In order to solve the above problems, the present application provides an underwater control module testing equipment, including: a support frame, which is a three-dimensional frame structure, including a top frame, a bottom frame and multiple side frames; and a base, which is arranged on the top surface frame of the support frame, and is used to fix the underwater control module on the support frame, and the shape and size of the base are adapted to the shape and size of the underwater control module; wherein, a hydraulic joint base plate is also provided on the support frame, and a hydraulic joint corresponding to the hydraulic joint on the underwater control module is provided above the hydraulic joint base plate, and the underwater control module is connected to the hydraulic joint of the hydraulic joint base plate when it is arranged on the base; a hydraulic steel pipe is connected to the bottom of the hydraulic joint base plate; the hydraulic steel pipe is divided into two outputs through a hydraulic three-way joint, one leading to an external test hydraulic output source and the other leading to a hydraulic test panel; the hydraulic test panel is used to perform hydraulic testing on the underwater control module; the external test hydraulic output source is used to provide multiple high-pressure and low-pressure hydraulic output power to external equipment or valves that can intuitively monitor the hydraulic power source. The external test hydraulic output source of the present application can simulate the state of the hydraulic signal source output by the seabed valve when it is received, and more intuitively observe the state of the underwater control module SCM during actual operation.

[0007] Through the underwater control module testing equipment of the present application, the connectors, hydraulic pipelines and detection instruments corresponding to the hydraulic pipelines for hydraulic testing are pre-set. As long as the underwater control module is placed on the support frame, the connection between the hydraulic connector of the underwater control module and the hydraulic connector of the testing equipment will be automatically completed, and then various required tests can be carried out without the need to connect the lines one by one, which greatly improves the work efficiency of the underwater control module quality inspection.

[0012] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clearer and more understandable, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0013] Words related to directions in this application, such as up, down, top, bottom, inside, outside, high, and low, are based on the position of the underwater control module test equipment in normal use.

[0014] The SCM is a key functional unit with a high degree of electromechanical and hydraulic integration in the subsea production system. During its service life, the SCM is required to provide an efficient, stable, and accurate hydraulic output source to the Christmas tree or manifold on the seabed, thereby opening or closing valves such as the annulus master valve (AMV), isolation valve (DCIV), throttle valve (PCV), production master valve (PMV), and safety valve (SCSSV). Therefore:

[0015] The present application provides an underwater control module testing device, comprising: a support frame, which is a three-dimensional frame structure, including a top frame, a bottom frame and multiple side frames; and a base, which is arranged on the top surface frame of the support frame and is used to fix the underwater control module on the support frame, and the shape and size of the base are adapted to the shape and size of the underwater control module; wherein, a hydraulic joint base plate is also provided on the support frame, and a hydraulic joint corresponding to the hydraulic joint on the underwater control module is provided above the hydraulic joint base plate, and the underwater control module is connected to the hydraulic joint of the hydraulic joint base plate when it is arranged on the base; a hydraulic steel pipe is connected to the bottom of the hydraulic joint base plate; the hydraulic steel pipe is divided into two outputs through a hydraulic three-way joint, one leading to an external test hydraulic output source and the other leading to a hydraulic test panel; the hydraulic test panel is used to perform hydraulic testing on the underwater control module; the external test hydraulic output source is used to provide multiple high-pressure and low-pressure hydraulic output power to external equipment or valves that can intuitively monitor the hydraulic power source. The external test hydraulic output source of the present application can simulate the state of the hydraulic signal source output by the seabed valve when it is received, and more intuitively observe the state of the underwater control module SCM during actual operation.

[0016] In one embodiment, a hydraulic test panel is provided on one of the side frames. The hydraulic test panel includes a plurality of test instruments, a high-pressure needle valve handle, a low-pressure needle valve handle, and a sampling port. The test instruments include a high-pressure hydraulic gauge and a low-pressure hydraulic gauge. The hydraulic test panel is used to simulate the state of one or more valves of the annulus main valve (AMV), isolation valve (DCIV), throttle valve (PCV), production main valve (PMV), and safety valve (SCS, SV) of the subsea control module when they are open.

[0017] In one embodiment, a hydraulic hose shelf is further provided on the support frame for storing hydraulic hoses for instruments. The hydraulic hoses for instruments are used to connect the test instruments on the hydraulic test panel and the hydraulic interface on the hydraulic steel pipe below the hydraulic joint base plate.

[0018] In one embodiment, a photoelectric flying wire connector shelf is also provided on the support frame. The photoelectric flying wire connector shelf is used to store the photoelectric flying wire connector of the underwater control module, and is used when the underwater control module is subjected to FAT testing and electro-hydraulic hybrid linkage testing.

[0019] In one embodiment, the support frame is a cubic frame structure with perforated sheet metal parts set on the side to block foreign objects.

[0020] In one embodiment, the perforated sheet metal is 3 mm thick and is installed on the side in a pull-out manner.

[0021] In one embodiment, the external test hydraulic output source is connected to an external device or valve via a hydraulic hose with a connection interface of 3 / 8'.

[0022] In one embodiment, the channel of the external test hydraulic output source is in a normally closed state when not in use.

[0023] In one embodiment, the base is funnel-shaped, wide at the top and narrow at the bottom, and is welded from 10 mm carbon steel plates.

[0024] In one embodiment, the main material of the hydraulic steel pipe is 316L, an outer diameter of 3 / 8', and a wall thickness of 2.3 mm.

[0025] The specific implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0026] like Figures 1a-1c The figure shows an underwater control module testing device provided by one embodiment of the present application, comprising a support frame 1 and a base 2. The base is a cubic frame structure, comprising a top frame, a bottom frame, and four side frames. The base 2 is welded or threaded to the top frame of the support frame. The base 2 is a square funnel-shaped structure, wider at the top and narrower at the bottom, welded from 10mm carbon steel plates. Its shape matches the shape and size of the underwater control module and is used to secure the underwater control module to the support frame 1. An inclined guide plate is also welded to the bottom of the support frame 1 to receive hydraulic fluid leaks.

[0027] The internal space formed by the support frame 1 is used to house the underwater control module, its testing instruments, and other necessary equipment. A hydraulic connector base plate 3 is also provided on the support frame 1 for hydraulic testing of the underwater control module. Hydraulic connectors 31 corresponding to the hydraulic connectors on the underwater control module are located above the hydraulic connector base plate 3, and hydraulic steel pipes 4 are connected below. The number and position of the hydraulic connectors 31 above the hydraulic connector base plate 3 correspond to the number and position of the hydraulic steel pipes 4 below, and the hydraulic steel pipes 4 are connected. The main material of the hydraulic steel pipes 4 is 316L hydraulic steel pipe with an outer diameter of 3 / 8' and a wall thickness of 2.3mm. If the hydraulic connector on the underwater control module is a female connector, the hydraulic connector base plate is provided with a male connector, and vice versa. When the underwater control module is set on the base 2, the hydraulic connector on the underwater control module is connected to the hydraulic connector 31 of the hydraulic connector base plate 3; the hydraulic steel pipe 4 is divided into two paths for output through the hydraulic three-way connector, one path leads to the external test hydraulic output source 5, and the other path leads to the hydraulic test panel 6; the external test hydraulic output source 5 is used to provide multiple high-pressure and low-pressure hydraulic output power to the external equipment or valve that can intuitively monitor the hydraulic power source; the external test hydraulic output source 5 is connected to the required external equipment or valve through a hydraulic hose with a 3 / 8' connection interface, which is easier to disassemble and assemble, and is convenient for temporary modification of the pipeline channel connection, making the use of the hydraulic test equipment more flexible. The channel of the external test hydraulic output source 5 is in a normally closed state when it is not needed. The external test hydraulic output source 5 of the present application can simulate the state of the hydraulic signal source output by the seabed valve when it is received, and more intuitively observe the state of the underwater control module SCM during actual use. The hydraulic test panel 6, mounted on one of the side frames of the support frame 1, includes multiple test instruments, a high-pressure needle valve handle, a low-pressure needle valve handle, and a sampling port. The test instruments, including a high-pressure hydraulic pressure gauge (0-20,000 psi) and a low-pressure hydraulic pressure gauge (0-10,000 psi), are used to simulate the open state of one or more of the subsea control module's annulus master valve (AMV), isolation valve (DCIV), throttle valve (PCV), production master valve (PMV), and safety valves (SCS, SV). The sampling port allows for efficient sampling of the medium (hydraulic fluid) from a specific hydraulic circuit or multiple circuits at any time during the hydraulic test, controlled by a corresponding manual valve, for particle size testing.

[0028] like Figure 2As shown, support frame 1 (without a base) is also equipped with a hydraulic hose rack 7 and an optoelectronic fly lead connector rack 8. These racks are located within the support frame, one on each side of base 2. Because the test instruments on hydraulic test panel 6 require hydraulic hoses to connect to the hydraulic ports on the hydraulic steel pipes below the hydraulic connector base plate to detect pressure on the corresponding hydraulic pipes, hydraulic hose rack 7 is used to store these hydraulic hoses. Hydraulic hose rack 7 includes multiple zigzag slots. Once placed in these slots, the hydraulic hoses can be coded and managed to avoid clutter and facilitate identification and management. In addition to various hydraulic tests, the SCM also requires electrical testing. These include FAT (Factory Automated Testing) tests, such as the high-pressure system withstand voltage test, the low-pressure system withstand voltage test, the return system withstand voltage test, the solenoid valve function test, and the pressurized separation test, as well as the aforementioned electro-hydraulic hybrid linkage test. Therefore, the optical / electrical fly-wire connector rack 8 is provided with multiple holes for arranging and organizing the SCM's optical / electrical fly-wire connectors, facilitating various electrical tests on the SCM on support frame 1. The optical / electrical fly-wire connector rack 8 can accommodate multiple models and functions of fly-wire connectors, allowing for ready debugging of the SCM's functions.

[0029] In use, the support frame 1 is equipped with perforated sheet metal parts on each side to prevent foreign objects. The perforated sheet metal parts are 3mm thick and are installed on the side in a pull-out manner to facilitate disassembly and assembly. During the hydraulic test, they can effectively prevent foreign objects from leaking pressure and causing safety accidents.

[0030] When the underwater control module SCM enters the test equipment, it can be directly hoisted by a crane to enter for testing. Alternatively, the underwater control module SCM dedicated installation equipment RT (SCM lowering and recovery tool) can be used to simulate underwater installation and docking.

[0031] The above description of the preferred embodiments of the present invention with reference to the accompanying drawings does not limit the scope of the present invention. Those skilled in the art may implement the present invention in various variations without departing from the scope and spirit of the present invention. For example, features of one embodiment may be applied to another embodiment to obtain yet another embodiment. Any modifications, equivalent substitutions, and improvements made within the technical concept of the present invention shall be within the scope of the present invention.
