Based on the next generation MEC (Magnetic Eddy Current) technique, Innospection’s capabilities in tank floor inspection with the MEC-Floorscanners are:

  • High sensitivity in detecting corrosion, pitting and local defects in tanks with
    • plate thickness up to 30mm
    • coating thickness up to 10mm
  • Ability to inspect lined and unlined carbon steel and stainless steel tanks
  • Ability to inspect overlapped welds in lined tanks
  • Direct sizing of defects during scanning without the need for Ultrasonic verification
  • Minimal surface preparation prior to inspection
  • High inspection speed of approx. 25m/min
  • Separate reporting for topside and underside defects

MEC (Magnetic Eddy Current) is a dynamic electromagnetic technique that offers the following benefits:

  • High sensitivity and reliability in detecting topside and underside defects including small and shallow pitting caused by bacterial corrosion (from Ø >3mm and 10% wall loss)
  • No coating removal or shot blasting of tank floor for a faster and more economical inspection operation
  • Analysis of defect severity in terms of volume and wall loss
  • Direct sizing of defects during scanning without the need for Ultrasonic verification with accuracy of +/- 10% for onsite reporting and +/- 5% for special offline analysis
  • Differentiation of defects from non-defects such as inclusions and laminations
  • Enables fast and efficient scanning and C-scan mapping of large areas
  • Low cleaning requirement prior to inspection

The MEC-Floorscanners are designed and built for the high speed and high performance inspection of storage tank floors. The TÜV certified MEC-F15 Floorscanner offers the following features:

  • Ability to scan right up to the tank shell guided by the wheels with minimal dead zone on annular zone area and floor plate overlaps
  • Improved signal to noise ratio for enhanced defect detection level
  • Shorter wheel distance for reduced influence from undulating or uneven floor plates
  • Rapid magnet on/off operation for faster positioning and manoeuvring from track to track during scanning
  • Ability to change the scanning lift-off for inspecting surfaces that are not well-cleaned

 

Accurate, reliable and repeatable real time inspection results are provided in real time in the form of an extensive colour condition mapping report with analysis of detected defects in terms of size, wall loss severity and location. In addition, the corrosion C-Scan mapping, statistical analysis overview, individual defect listing and repair plate report are also provided.

The comprehensive reporting software for the MEC-Floorscanners provides accurate, reliable and repeatable real time inspection results are provided in real time. The advanced colour condition mapping report provides an analysis of detected defects in terms of size, wall loss severity and location. Separate reports are also generated for the topside and underside conditions.
