  Automatic Coiled Tubing Integrity Monitoring (ACIM)  

Alarm options
Since for operators it is not practical to incessantly control the results of the monitoring process, individual alarms on all determined CT parameter are definable.
If the alarm option is enabled and the respective monitoring result is out of operator defined valid range an alarm will be executed visual and acoustical on the evaluation computer.

Monitoring results are:
  • Measured depth/length of the coiled tubing
  • Calculated velocity
  • Measured outer diameter (minimum, maximum, average)
  • Calculated ovality (out of roundness)
  • Evaluated wall thickness
  • Evaluated metal loss, flaws, corrosion

Resolution and Accuracy
The minimum depth of surface flaws in percentage of the coiled tubing wall thickness can be detected automatically with a probability of 90% versus the width of the metal loss. Since the coiled tubing is magnetized in axial direction, the ACIM system is capable to detect automatic transverse oriented flaws and three-dimensional defects such as cracks, cuts and general corrosion. Also, corrosion with longitudinal direction will be detected as long as the defect has sufficient transverse components to generate detectable magnetic filed disturbance.

The ACIM offers:
  • Coiled Tubing Integrity at glance during on- and offshore operations;
  • Coiled Tubing management system for quality control and life-time prediction;
  • Integration into existing coiled tubing equipment and procedures;
  • Quick and easy to install and to remove at any time operation;
  • Continuous measurement of tube condition during operation;
  • Storage of inspection results to monitor defect growth rates and changes in tube geometry;
  • Real time determination of the coiled tubing outer diameter, ovality and wall thickness;
  • Automated detection of metal loss caused by corrosion, manufacturing failures or mechanical damage;
  • Automated detection of pinholes, transverse cracks and butt welds;
  • Real time visualization and individual alarms for the evaluated data;
  • Operation in hazardous areas (Zone I and Zone II);
  • Certified for Zone I operation in hazardous areas;
  • Worldwide unique inspection tool for coiled tubing;
  • Detailed on-line information on- and offshore.
