LinearScanner™
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.
LinearScanner™
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

Transforming FPSO Hull Inspections: A Cost-Effective, In-Service Solution with ORCA.
The FPSO in question is a single-hull vessel originally built in 1981 and later converted into a disconnectable FPSO in 2008. It is classed by Lloyd’s Register and has operated under a periodic inspection regime since its conversion, with a dry dock Special Survey 8...
ARTEMIS: Through-Coating Inspection for Large-Diameter Subsea Pipelines.
A primary objective was to assess areas expected to become dead legs as a result of future pipework rearrangements. These dead legs, along with the commingling point for flow back to Nyhamna, have been assessed as susceptible to Flow-Assisted Corrosion (FAC),...
