Embodiment Construction

[0025] The surface damage data detection of underwater equipment will use ACFM AC electromagnetic field technology. ACFM is a new non-destructive testing technology developed from the AC potential drop and eddy current testing methods. Its principle is to uniformly induce alternating current in the equipment. Detect changes in the magnetic field on the surface of the equipment to achieve defect assessment. This technology has the following advantages, non-contact detection, qualitative and quantitative detection is completed at one time, no calibration is required, it can penetrate metal and non-metal coatings, and can accurately detect the length and width of damage, no need to clean the surface covering during detection, high Stability, high resolution. The ACFM detection method has been certified by DNV, ABS, BV, etc., confirming that the use of ACFM in the detection of offshore oil equipment is an important method for underwater equipment detection.

Abstract

The invention discloses a detection system for surface damage data of underwater equipment. An ACFM array probe is carried, moved, and operated by an underwater robot. The data obtained by detecting the underwater equipment by the ACFM array probe is transmitted to an underwater module for data conversion. Then, an image is transmitted to a water module by an umbilical cable. A computer system connected to the water module analyzes the image, and records and archives the results of the detection analysis. According to the detection system, the current or random state of the underwater equipment can be understood and grasped, and the development and change trend of the underwater equipment over the years are recorded. A correct assessment of the structural integrity of the underwater equipment is made and a reasonable maintenance strategy is proposed by calculation and analysis. Therefore, the safety of the underwater equipment is guaranteed, and the necessary data and theoretical basisare provided for decisions when major measures are taken.

Description

technical field [0001] The invention is applicable to the field of offshore oil industry, and in particular relates to a data detection system for underwater equipment surface damage. Background technique [0002] The ocean is rich in oil resources. With the development of the offshore oil industry, the proportion of offshore oil production in the total oil production is increasing. In recent years, my country's offshore oil exploration and development has made great progress, and there are already many oil and gas facilities and offshore oil professional equipment. [0003] The offshore oil industry is one of the industries with the greatest safety risks. According to ≤ Offshore Oil Safety Production Regulations ≥ (Decree No. 4 of the State Administration of Work Safety), offshore oil equipment constitutes the basis for the development of the offshore oil industry, so their safety is guaranteed , in order to ensure the safety of offshore oil facilities. Offshore oil equip...
