Remote operated vehicle for subsea pipeline detection

Abstract

The invention provides a remote operated vehicle for subsea pipeline detection. The remote operated vehicle for subsea pipeline detection mainly aims to solve the problem that a traditional ROV provided with a cable is prone to being influenced by an ocean current and subsea complicated environments. The remote operated vehicle for subsea pipeline detection is characterized by comprising a ROV body, a pipeline clamping and walking device and a detecting device. The ROV body is used as a carrier to provide power for a pipeline clamping device and walking devices and mainly comprises a carrier frame, mechanical arms, vertical propellers, horizontal propellers, a buoyancy module, a pressure-proof bin, a pan-tilt and a hydraulic oil tank. The pipeline clamping and walking device is mainly used for clamping a pipeline so as to ensure that inwards-recessed wheels are tightly attached to the pipeline for walking. The dimension of the pipeline clamping device can be adjusted so that the pipeline clamping device can be suitable for pipelines of different diameters. The detecting device completes comprehensive detection of the subsea pipeline through various sensors and multiple kinds of detecting equipment with a supporting ship as an operation platform. By the adoption of the remote operated vehicle for subsea pipeline detection, the problems that the ocean current influences the measurement stability, and the surrounds are damaged when propellers of the traditional ROV operates can be relieved.

Description

technical field [0001] The invention relates to an operating machine used in the field of underwater operations and capable of performing omnidirectional detection of submarine pipelines. Background technique [0002] As my country's offshore oil and gas development, especially deep-water oil and gas exploration and development becomes increasingly active, there are more and more submarine pipelines as an important part of oil field development and production. The detection of submarine pipelines has become particularly important. Submarine pipeline inspection ROVs mostly use floating cabled underwater robots (ROVs). Although the related technologies are relatively mature, floating ROVs use propellers to navigate underwater to detect submarine pipelines, which are vulnerable to ocean currents and complex environments on the seabed. In order to ensure the detection quality of the detection device during the detection process, it is necessary to precisely control the speed an...
