Aqua MTM Technology

Aqua MTM Technology

Aqua MTM® is a non-intrusive tool, based on Magnetic Tomography Method (MTM) used for subsea pipeline inspections, jointly-developed by PETRONAS with Transkor-K. It evaluates defects in metal and weld joints, monitors any development of corrosion and assesses the state of corrosion based on the relative change in local stress levels in the pipeline. This has an advantage over subsea inspection of unpiggable pipelines done using a temporary launcher and auxiliary pumping to run an Inline Inspection (ILI) tool, which is often costly even for short distance pipeline.

The MTM carries no risk to pipelines, as it does not:

  • Does not require special equipment and preparation (equip pipeline with pig trap, cleanout, geometry inspection, pipeline inner surface preparation, route marking)
  • Does not require direct contact with a pipeline or changes to pipeline operation mode before the inspection.
  • Provides integrity monitoring of pipeline.
  • Compares different types of defects by relative level of stressed conditions and initiates a repair schedule on the basis of serviceability calculations for the actual operation conditions of pipelines.
  • It suits any pipeline with ferromagnetic properties especially the non-piggable subsea pipelines or any subsea pipelines which exclude an intrusive inspection method due to operation limitation.
