Erosion simulations is a highly theoretical exercise and provides only indication of area and severity of predicted erosion impact, based on single entry values for particle size and flow variations.

Subsea ultrasonic erosion monitoring for bends

The FORCE Guide Bend-scanner enables accurate monitoring of the entire subsea pipe bends. Using preinstalled guide posts and immersion ultrasonics, we collect high-quality data from the exact same locations over time, supporting confident assessment of erosion and integrity management. The same tooling is used for both baseline and follow-up inspections, ensuring consistency and comparability of results throughout the lifetime of the asset.

Key benefits 

  • High reliability: precise relocation enables true change detection
  • Operational efficiency: reduced vessel time through quick scanner deployment
  • Broader insight: scanning covers larger bend areas than point sensors
  • Flexible application: suitable for any bend size and radius
  • Proven tooling: FAT/SIT performed on actual subsea hardware 

How the solution works

For accurate measurements, we use the ultrasonic immersion technique. It is well suited for thickness measurements and corrosion mapping because it is less sensitive to the exact distance between the probe and the surface. The uniform coupling provided by the sea water between the transducer and the surface enables high scanning speeds. The transducer is mounted in a holder that keeps it aligned perpendicular to the material surface during movement, ensuring stable sound propagation and high-quality ultrasonic signals.
