Aqua MTM® is a non-intrusive tool, based on Magnetic Tomography Method (MTM) used for
subsea pipeline inspections, jointly-developed with Transkor-K. It evaluates defects in metal and
weld joints, monitoring any development of corrosion and assessing 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 pipelines.
