Our technology


KMD-02R is designed for non-contact magnetometer diagnostics of underwater pipelines at depths up to 1200 m. Complexes of non-contact diagnostics are developed on the basis of three-component magnetoresistive nanofilm sensors that allow to measure conditions of high electromagnetic interference.

System KMD-02R:

  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.


Before starting work our specialists together with ROV technical team install the device on the device with maximum distance from its metal parts. In the process of diagnostics ROV with the device connected moves along the pipeline route. At the moment of measurement the received data are transmitted via cable to the ROV control center located on the accompanying ship. If it is technically possible, verification diging is carried out based on the diagnostics results in order to obtain more accurate information about the pipeline and to 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.

Additional technical informationabouttheKMD-02R:

Type of sensors (primary transducers)

Nano-size sensors based on the Anisotropic Magneto-Resistance effect (AMR).

Each sensor consists of magneto-resistance layer made of Fe-Ni-CO layer, with the thickness of 30 nM (nano-Meter, 10-9m)
Amount of measured parameters of the magnetic field
Sampling speed
Up to 300 samples per second
Types of detectable defects

  • Metal loss (internal or external corrosion: local corrosion pits, groove corrosion);

  • Crack-like defects (cracks, including SCC, folds, blister, guide marks);

  • 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

Depth of detectable defects
starting from 15 to 100 % of pipe wall thickness
Determination of pipeline bedding depth 
Up to 10 diameters of the inspected pipe
Requirements to the surface under inspection
preparation of the surface and changes in pipeline operation mode - Not required
