Non-Contact Magnetometry Inspection Technology
NCM is a non-intrusive or non-contact method for inspection of steel pipelines – even when such pipelines are buried, without requiring de-burial of the pipes.
It works by identifying changes along a pipeline’s magnetic field which are caused by stress, tension or corrosion. The received data is visualized in real time and shows the locations of anomalies along the pipe, complete with GPS coordinates.
Subsea Pipeline Repair Robots
The Nautilus and Oktapous are subsea robots that are designed to perform inspection, repair and maintenance tasks on subsea pipelines and risers with minimal human intervention and a very light footprint.
These robots have the distinct advantage of being able to assess, clean and repair subsea pipes in a single operation without requiring divers and most of the conventional vessel-supported equipment.

Advantages of NCM
NCM inspections can identify anomalies that are caused by the following types of problems on pipelines:
- Metal Loss
- Crack-like Defects
- Pipeline Geometry Changes (loss of stability)
- Stress-strained Condition
- Mechanical Damage
- Weld Anomalies
NCM can easily be deployed onshore and can also be deployed subsea by a diver or mounted on an ROV. The device is lightweight and is rated for a water depth of 2000m.
The innovative and field-tested Non-Contact Magnetometry (NCM) method from Hazaika Energy is the ideal solution for inspecting buried pipes. It was developed in response to the challenges faced by operators when inspecting such pipelines.
