Our technology


KMD-02D is designed for non-contact magnetometric diagnostics of subsea pipelines at depths up to 60 meters. Systems of non-contact magnetometric diagnostics are developed on the basis of three-component magnetoresistive nanofilm sensors that allow to measure conditions of high electromagnetic interferences.

System KMD-02D:

  1. Is completely passive - do not emit electromagnetic or other radiation and do not have any effect on the object under investigation;
  2. Does not require changes in the pumping mode of the product
  3. Does not require pipeline preparation for inspection.


During the survey, the diver moves the vertically oriented instrument along the pipeline route. All received data are graphically displayed on the screen of the device online. The device design allows the diver to enter a number of markers into the file directly during the survey. All received materials are recorded on a flash memory card.

In case of technical capability, verification diging is carried out based on the diagnostic results in order to obtain more accurate information about the pipeline and improve the quality of processing. Further, the analytical center performs a multi-profile data analysis using artificial intelligence technologies. Based on the results, a report on the technical condition of the pipeline is prepared.

  • Discontinuity (lamination, non-metallic inclusions); Weld joints defects;

  • Change in geometry (dents, corrugation);

  • Anomalies of stress-deformed state (sections with sags, deflections, karsts and landslip phenomena);

  • Other defects causes changing of the magnetic field
