Aqua-MTM (Magnetic tomography method)
a technology developed by RDC «Transkor-K» (Russia)in frame of a joint development agreement with
PETRONAS (Malaysia).
Designed for remote evaluation ofstress-defomed state of offshore underwater steel pipelines of any purpose intended to be used with an underwater remotely operated vehicles (ROV).
Company profile:
for the First time – evaluation of the technical condition of pipelines taking into account the operating local voltages in real operating conditions.
for the First time – remote detection of areas with anomalies of stress-strain state due to General and local loss of stability, in areas of landslide loads, currents, free sags, seismic active zones, weak soil bearing capacity, in conditions of laying in mountainous and marshy areas.
Declared level of detection of VAT (POD) anomalies – not less than 65 % (depending on the design of the object) in the established range of mechanical stresses. Forecasting parameters in all VAT anomalies: safe operating pressure, period of trouble-free operation (Y-percent resource), assessment of the danger of destruction due to a combination of defects and increased loads.
MTM has been successfully tested in industrial pipelines, including those not subject to in – line inspection-more than 20 thousand km in depth to 26 m with a high probability of anomalies detection.

The quality control of the ROV is also carried out by the supervisor of the AQUA MTM team, and software AQUA SKIF.
Probability of detecting defective areas:
0%
The probability of interpreting the degree of danger:
0%
The probability of missing a dangerous defect:
0%
The technology "AQUA-MTM allows for the whole length of the object to reveal the anomalies of VAT, associated with defects of metal of any types.
In addition, for the first time in WORLD PRACTICE, anomalies of the stress-strain state are revealed: in the areas of sags, deflections, torsions, increased loads due to currents, ice impacts, seismic activity leading to local or general loss of stability of the pipeline
