Spectrum Laser Scanning with Handyscan and Pipecheck


Increased accuracy and repeatability compared to traditional measurements methods such as pit gauge, UT probes and single-line lasers.



Spectrum uses the Handyscan 3D laser scanner and the Pipecheck data acquisition/analysis software for fast, reliable and accurate pipeline inspections. Using triangulation and binocular vision, the Handyscan 3D scanner can self-position itself to a unique dynamic referencing system on the pipeline, which ensures high measurement repeatability and accuracy. The resulting 3D scan is perfectly scaled to be representative of the real geometry and allows easy visualization of surface defects.

Advantages of the Handyscan 3D laser scanners include:

  • Can be carried on site very easily (1-kg scanner and laptop only)
  • The scanning speed can be more than 10 times faster than the pit gauge technique considering the time to setup, inspect, analyze and generate a report
  • The scanner is self-positioned to the pipe. No need for encoders or bulky mechanical scanners to reference the data
  • Resulting dynamic link between pipe and scanner preserves accuracy and resolution in any field vibrating environment
  • The quality of the acquired data can be verified in real time during the acquisition. The results are generated in a few minutes
  • Repeatability of results is ensured by scanner design and auto-generated reports (within ± 50 micron accuracy)
  • Inspector’s skill level has no impact on scanning process and analysis
  • Follows code regulations (ASME B31G code)


Pipecheck is a single software data acquisition and analysis platform addressing both pipeline external corrosion and pipeline mechanical damage. The external corrosion module offers very fast and reliable data processing that generates instant, on-site results. The mechanical damage module features numerous key functionalities that increase dent understanding and facilitate decision making, with instant results generated on site.

Key functionalities include:

  • Automatically-applied interaction rules
  • 3D and 2D color mapping with river-bottom path overlay
  • 2D section generation in both axes
  • Worst-case-profile generated for all corrosion features
  • Estimated burst pressure calculation based on ASME B31G code (B31G, B31G Modified and Effective Area methods)
  • Corrosion depth measurement, dimensions and position on the pipe
  • “Depth-on-the-fly” — simply drag the mouse over point to obtain local corrosion depth measurement
  • Gouge and redressed gouge inspection
  • Point-to-point distance measurement directly in the 3D model
