BEST MODE FOR CARRYING OUT THE INVENTION

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

1 shows a method for detecting an offshore oil and gas underwater device by an onshore analog ROV according to an embodiment of the present invention.

In this embodiment, the marine oil and gas underwater equipment is a deep water base plate. Specifically, the method for detecting the offshore oil and gas underwater equipment by the onshore simulated ROV includes the following steps:

[0028] SO: The ROV, the ROV control room, the hydraulic power station, the retractable cable winch and the generator are connected to each other to complete the connection of the device. Wherein, the ROV is hydraulically driven, and the ROV is powered by a hydraulic power station (ie, HPU) matched with the ROV, and the hydraulic power station is connected to the ROV. The ROV control room is connected to the ROV to control and view the ROV test results, such as viewing the ROV's camera-monitored video. The retractable cable winch is connected to the R OV to control the length of the umbilical cable based on the distance between the ROV and the ROV control room. Generator and The ROV control room is connected to the retractable cable winch. After completing the connection and commissioning of the corresponding equipment, connect the lifting point above the ROV to the crane.

[0029] S1: Leave the ROV floating and control the ROV to operate at a constant temperature. Specifically, the ROV is suspended by a 15 ton crane, and the ROV is limited in the diagonal direction during the lifting process. After the suspension is completed, the ROV is taken down, and the ROV is continuously flushed and cooled by the fire hose to make the ROV work under constant temperature to avoid the ROV temperature being too high during the detection process. normal work

[0030] S2: Control the ROV to conduct a path test to the marine oil and gas underwater equipment. Specifically, the control ROV is moved to the operation hole position and the observation hole position of the marine oil and gas underwater equipment according to the preset path, and the cable winch is controlled to recover or lower the umbilical cable to complete the path test. During the path test, the ROV is limited by moving the limit rail to prevent the ROV from deviating from the preset path to avoid the left and right swing, which causes the ROV to collide with the structure of the marine oil and gas underwater equipment. Specifically, the operating hole is disposed on a protective frame of the marine oil and gas underwater equipment. Understandably, in the suspended state, if the ROV can reach the ROV operation hole and the observation hole position without barrier (ie, the ROV will not collide with the protection frame), the path test passes, otherwise it is regarded as unqualified.

[0031] S3: Control the ROV to perform the test of reading the identification information of the marine oil and gas underwater equipment. Specifically, the imaging device set on the control ROV collects the identification information of the surface of the marine oil and gas underwater device, and performs the engraving in the ROV control room. The identification information includes a tick mark and a medium flow direction indication arrow, a TN mark and a PN mark, and an operation hole mark set on a protection frame of the marine oil and gas underwater device, which is disposed on the anti-sink plate of the marine oil and gas underwater device, wherein TN The identification and PN identification refer to the true north and platform north logos, respectively, for pointing to the underwater orientation of marine oil and gas underwater equipment. Understandably, in the process of suspending the ROV, it is necessary to limit the ROV in the diagonal direction. The identification of the identification information can facilitate the correct identification of the position of the marine oil and gas underwater equipment to protect the normal operation of the ROV. get on.

[0032] S4: Control the ROV to complete the operation test of the operation hole and the observation hole of the marine oil and gas underwater equipment, to simulate the operation of the ROV on the installation process of the marine oil and gas underwater equipment, thereby ensuring the ROV under the underwater oil and gas underwater equipment The installation is smooth. As shown in FIG. 2, step S4 includes:

[0033] S41: controlling the crane to lower the ROV to the surface of the marine oil and gas underwater equipment, controlling the ROV to open the operation hole and the observation hole cover on the protection frame of the marine oil and gas underwater equipment, and operating the hole and View Check the hole for identification. Specifically, identifying the operation hole and the observation hole of the ROV includes identifying the indication 0/S of the valve operation hole and the 0/S indicating the hole using the ROV camera.

[0034] S42: Restoring to the land, the control ROV assembles the hydraulic torque wrench for the marine stern valve to the ROV mechanical arm.

[0035] S43: The crane lifts the ROV again, controls the ROV to go to the operation hole of the marine oil and gas underwater equipment, inserts the hydraulic torque wrench into the operation hole, and after completing the matching operation, pulls out the hydraulic torque wrench. Understandably, in this process, the observation hole is viewed through the camera device on the ROV to control the hydraulic torque wrench on the ROV to complete the matching operation.

[0036] S44: The ROV is lifted again to the land, and the ROV is controlled to unwind the hydraulic torque wrench from the arm to complete the disassembly of the hydraulic torque wrench.

[0037] S45: lifting the ROV again, going to the protection frame top plate of the marine oil and gas underwater equipment, controlling the ROV to use the mechanical arm to close the operation hole of the marine oil and gas underwater equipment and the cover of the observation hole, and complete the ROV operation test.

[0038] It can be understood that after the completion of step S45, the connection of the ROV, the ROV control room, the hydraulic power station, the retractable cable winch and the generator is removed, and the ROV detecting device is recovered.

[0039] The invention is implemented, and the marine oil and gas underwater equipment is tested by simulating ROV on land, and the physical ROV is applied to the ROV test of the marine oil and gas underwater equipment to determine whether the ROV interface is reasonable and whether the underwater can be successfully completed. Operation, to ensure that ROV can be smoothly applied to the underwater installation process of marine oil and gas underwater equipment, avoiding the fact that ROV can not smoothly install marine oil and gas underwater equipment in actual application, affecting the smooth progress of seawater oil and gas bursting process, leading to the project Continuation and cost increase.
