Defect repairing tool for submarine pipeline

Abstract

The invention provides a defect repairing tool for a submarine pipeline. The defect repairing tool for the submarine pipeline comprises a clamping module structure, a coating module structure and a coiling module structure, wherein the coating module structure capable of forming a coating layer on a defect area of the submarine pipeline to be repaired is connected to one side of the clamping module structure which is controlled through a remote operated vehicle (ROV) and capable of clamping the submarine pipeline to be repaired; the coating module structure sleeves the outer wall of the submarine pipeline to be repaired in a circumferential opening-closing manner and can axially move along the submarine pipeline to be repaired; the coiling module structure capable of forming a coiling layer on the coating layer is connected to one side, far away from the clamping module structure, of the coating module structure; the coiling module structure can axially move along the submarine pipeline to be repaired and can be rotated around the submarine pipeline to be repaired. The repairing tool is operated through the ROV, so that the maximum diving depth of workers can be overcome; the repairing process is continuous, complete and high in efficiency; and the problem of defect repairing of the submarine pipeline in a deep water environment can be solved.

Description

Technical field [0001] The invention relates to the technical field of submarine pipeline repair, in particular to a submarine pipeline defect repair tool, which is especially suitable for the operation of underwater robots (ROV) in a deep water environment. Background technique [0002] Submarine pipelines can be called the economic "lifeblood", and their safety directly affects energy production efficiency. The complexity and randomness of the marine environment make submarine pipelines often cause small defects due to corrosion, cracks, and third-party damage during service, which can seriously cause the leakage of marine oil and gas resources and bring adverse consequences to the environment and economy. [0003] When repairing defective parts of a submarine pipeline in a deep water environment, there are the following problems: (1) Low visibility, active ocean currents, diverse sediments and other marine environments that are unfavorable for man-made diving operations; (2) Sho...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a kind of defect repairing tool for submarine pipelines, which overcomes the problems of poor operability, low engineering applicability, and unsuitability for deep seas in the prior art. The repairing tool is operated by an underwater robot (ROV) to overcome The limit of personnel diving is exceeded, the repair process is continuous and complete, and the efficiency is high, which solves the defect repair problem of submarine pipelines in deep water environment
