Underwater photogrammetry inspections


Available globally from Ashtead Technology

Do you need to perform an underwater photogrammetry inspection?

Ashtead Technology and Welaptega can offer photogrammetry inspections globally.

3DM uses advanced photogrammetry to quantify the geometry of subsea components. The system is deployed offshore by Welaptega’s team of specialized engineers to generate dimensionally accurate models, from which a number of analysis can be performed, including:

  • Overall component dimensions
  • Linear and angular offsets
  • Radius of curvature
  • Cross-sectional areas
  • Depths, widths, and heights
  • Volume of material
