The robust, field-proven TSC Subsea Linear Scanner is a compact, remotely deployed scanning solution specifically designed to fit into restricted-access areas where other inspection scanners simply won’t fit. It is positioned onto the inspection area via an ROV.


The scanner’s automated linear scan action ensures smooth and consistent real-time data capture, maximising array probes to cover up to 100% of the inspection area. Once placed in position by the ROV, built-in passive compliance ensures good probe contact during scanning. The LinearScanner™ actively measures the travel distance of the probe, resulting in accurate defect position and sizing.

The LinearScanner™:

  • Scans straight welds, e.g. corner fillet welds
  • Scans 200mm in 10 seconds
  • Is compact enough to fit into restricted areas others can’t access
  • Uses cameras and mirrors to allow operators to observe the probe during scanning
  • Enables interpretation of the data in real time while storing the raw data for later use
  • Has a low false-call rate
  • Is tolerant of residual marine growth and material coatings

Remote Subsea Inspections

The challenge Risers, and the riser guides that hold them in place, are subject to severe environmental conditions that often lead to fatigue damage. Failure of these structures could be potentially catastrophic so they must be inspected regularly to ensure structure...
