A game changing inspection device
Truly remote pipeline inspection technology. The result of years of research into stress magnetization.
Leading the way forward
In partnership with the University of Leeds, we've engineered the science of stress-magnetization to create a remote pipeline inspection tool which is used by integrity engineers worldwide on both piggable and non-piggable lines. This groundbreaking technology is called Stress Concentration Tomography, commonly referred to as SCT™.
Comprehensive inspection
The only inspection technique in the world that can map the lateral position and depth of cover of the pipeline while providing comprehensive defect detection.
Innovative technology
Using magnetic signatures to detect wall defects, weld defects, corrosion, SCC, physical features, lateral position and depth of cover.
Resource efficient
Save money by limiting excavations to segments where corrosion is present under reported damaged coatings.
High resolution screening
Provides the ability to screen a pipeline to locate areas of further investigation with high resolution tools.
Corrosion monitoring
Monitor the growth of known areas of corrosion in specific sections of longer pipelines
No changes required
SCT™ does not require energy induction into the pipeline prior to inspection, nor changes to pipeline flow rate or CP currents.
Identify issues
Locate internal and external corrosion, dents and weld defects as well as locations of illegal hot taps and stuck PIGS.
Enhanced accuracy
Save money by excavating in the right place for repairs using sub-meter accurate GNSS capabilities.
Comprehensive defect detection
A cost-saving addition to existing methods, weighing less than 8kg and requiring only a 2-man team to operate in the field, UNISCAN™is rapidly mobilized and can be deployed in many different environmental conditions.
1. A stand-alone device
SCT™ offers a solution to pipeline operators in geo hazardous areas worldwide. It’s 3D mapping function and stress estimation capacity can report bending strain and can identify the exact location at which earth movement is leading to an imminent pipeline rupture.
2. Monitoring
By targeting specific sections to monitor known defects on a longer pipeline, SCT™ eliminates the need to initiate a full-length PIG run. This means less downtime and more savings.
3. Mapping
Use SCT™ to deliver an accurate map of the pipeline route including its depth of cover. Especially useful in areas of soil erosion where deployed in this way it will help reduce the possibility of damage through mechanical impact from farming and excavation equipment.
4. Screening
SCT™ can be used to scan a long length of pipeline and then to identify segments that need further investigation using high resolution tools. By zooming in on specific regions of a pipeline the need to inspect entire long lengths with high resolution tools is removed saving time and cost.
Introducing UNISCAN
is the hardware used to collect raw data for analysis. It carries an array of magnetometers that collect the pipeline’s magnetic field in multiple dimensions and an onboard data logger that provides an LED display unit for the field operator to use as he walks along the axis of the pipe.
Complement ILI
and ECDA with SCT
Most pipeline operators have experienced unexpected additional excavation costs when repairing pipes following ILI reports especially when positioning is based on girth welds. They have also experienced excavations following DCVG reports of damaged coatings only to find no corrosion has initiated in the metal.
