Embodiment Construction

[0047]In the related art, it is necessary to use a ship and an integrated workover control system (IWOCS system) for pressure testing. When the water depth is large, because the distance between the integrated workover control system and the umbilical cable to be tested is relatively large, it is necessary to extend the umbilical cable that comes with the integrated workover control system into the umbilical cable to be tested underwater, and pass the underwater robot (ROV robot) controls the umbilical cable pipeline of the integrated workover control system to dock with the umbilical cable pipeline to be tested, and presses the umbilical cable pipeline to be tested through the umbilical cable pipeline of the integrated workover control system. After the pressure is completed, it is necessary to maintain the pressure of the pipeline of the umbilical cable to be tested for a period of time, and observe the pressure drop in the pipeline of the umbilical cable to be tested. If the...

Abstract

The invention provides an underwater umbilical cable pressure testing device, relates to the technical field of umbilical cables, and is used for solving the technical problems of higher constructiondifficulty and higher risk when pressure testing is carried out on an umbilical cable. The device comprises an umbilical cable connector, a testing manifold and a pressure pump set which are located underwater during testing. The umbilical cable connector is used for being connected with a to-be-tested pipeline in an umbilical cable to be tested. The test manifold comprises a connecting manifold,and the connecting manifold is connected with the umbilical cable joint; and the pressure pump set is used for pressurizing the test manifold so as to pressurize a to-be-tested pipeline in the to-be-tested umbilical cable. The device provided by the invention is used for reducing the construction difficulty during umbilical cable pressure testing and reducing the risk of umbilical cable pressure testing.

Description

technical field [0001] The invention relates to the technical field of umbilical cables, in particular to an underwater umbilical cable pressure testing device. Background technique [0002] During the development of offshore oil and gas resources, the operation of the underwater production system is usually controlled by the above-water platform facilities. As a device connecting the above-water platform facilities and the underwater production system, the umbilical cable has lines for transmitting power and signals for underwater equipment, as well as pipelines for controlling the opening and closing of underwater equipment and transporting chemicals. [0003] After the umbilical cable is laid, in order to ensure the normal operation of the umbilical cable, it is necessary to perform a pressure test on the umbilical cable pipeline, that is, to pressurize the umbilical cable pipeline and keep the umbilical cable pipeline for a period of time to test the umbilical cable sea...
