Jacket corrosion detection equipment and method free of magnetic field interference

Abstract

The invention discloses a jacket corrosion detection equipment and method free of magnetic field interference. The jacket corrosion detection equipment comprises a control and data real-time interaction system, a release and recycling system, a umbilical cable and a jacket corrosion detection crawling robot, wherein the jacket corrosion detection crawling robot is used for detecting the corrosionconditions of a jacket sea wave splash zone and a jacket underwater zone, the control and data real-time interaction system is used for controlling the robot in real time, analyzing and storing measuring data detected by a corrosion detection unit and providing power for the jacket corrosion detection crawling robot, and the release and recycling system is used for releasing and recycling the robot. The method uses the jacket corrosion detection equipment to achieve the full-range detection of an offshore platform jacket. By the jacket corrosion detection equipment and method, offshore platform jacket corrosion electric field detection free of electromagnetic interference and motion interference can be achieved, and detection result accuracy is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of offshore platform detection, in particular to jacket corrosion detection equipment and a corrosion detection method without magnetic field interference. Background technique [0002] With the advent of the era of marine economy, there are more and more various offshore facilities, such as offshore platform jackets, sea-crossing bridges, seawall dams, ships and deep-sea submersibles, etc. Most of the marine structures adopt coating and cathodic protection joint protection. The metal structure of the offshore platform is affected by factors such as sunshine, sea wind, wave impact, complex seawater system, diurnal and seasonal temperature changes, and marine biological erosion, which makes the corrosion rate of the offshore platform faster, and the corrosion resistance of metal materials varies with exposure conditions. different changes. The splash area is affected by factors such as wind, waves, sunlight...

Problems solved by technology

However, most of the traditional underwater detection technologies are point-to-point detection methods, which can only detect the conditions within the coverage of the sensor. The inspection efficiency is low, and it is difficult to conduct a comprehensive corrosion detection on the jacket
