Subsea pipeline cleaning device

Abstract

The invention discloses a subsea pipeline cleaning device. The subsea pipeline cleaning device comprises a frame, a front-end sediment flushing module, a driving walking module, a subsea pipeline cleaning module, a floating block module, a power module, a sensing module and a communication control module, wherein the frame forms the main body supporting structure of the device; the front-end sediment flushing module is arranged on the frame and flushes sediment on a subsea pipeline; the driving walking module is arranged on the frame and drives the frame to march forward along the subsea pipeline; the subsea pipeline cleaning module is arranged on the frame and cleans the subsea pipeline. The subsea pipeline cleaning device is adapted to subsea pipelines with different pipe diameters and integrates sediment cleaning with subsea pipeline cleaning; the work efficiency is improved; the job content of a remote operated vehicle (ROV) is greatly reduced; the subsea pipeline cleaning device can be carried to the subsea through the ROV and starts autonomous working; different sensors can be integrated on the mechanism to conduct preliminary appearance inspection on the pipeline; revolving brushes can be chosen from different materials such as wire brushes and bristle brushes according to adhesion conditions of marine life.

Description

technical field [0001] The invention relates to the technical field of submarine pipeline maintenance, in particular to a submarine pipeline cleaning device. Background technique [0002] With the development of deep-sea oil and gas fields, the total amount of submarine oil and gas pipelines has increased rapidly, and submarine oil and gas pipelines are affected by seawater salinity, temperature, undercurrents, marine organisms, chemical substances in oil and gas, etc., resulting in corrosion, scaling, and serious even Leakage occurs, causing huge economic losses and environmental pollution. [0003] At present, the corrosion monitoring and detection methods of submarine pipelines include intelligent sphere, camera, ultrasonic thickness measurement, FMD, CT, PEC, etc., and ROVs carry corresponding detection tools for detection. However, since only part of the sea pipe is exposed on the seabed and part is buried in the sand, the marine organisms attached to the surface of th...

Problems solved by technology

However, since only part of the sea pipe is exposed on the seabed and part is buried in the sand, the marine organisms attached to the surface of the sea pipe will cause certain obstacles to the corresponding detection, and the sea organisms attached to the sea pipe will accelerate the corrosion of the sea pipe
