3DM uses advanced photogrammetry to quantify the geometry of subsea components. The system is deployed offshore by our specialised team of engineers to generate dimensionally-accurate models.

We can measure overall component dimensions; linear and angular offsets; radius of curvature; cross-sectional areas; depths, widths and heights and volume of material. Our models can be exported for finite element analysis (FEA).

The 3DM track record to date includes:

  • Wellheads
  • Trees
  • Manifolds
  • BOPs
  • Risers
  • TLP tendons
  • Flanges
  • Anodes
  • Jacket structures
  • Mooring components
  • Pipelines
  • 3DM is non-destructive
  • Data is collected while components are in water and operating
  • Minimal ROV time required - component surfaces require only basic cleaning and little setup
  • Flexible subsea deployment - 3DM can be deployed by work class or eyeball ROVs as well as divers or rope-access technicians
  • High-quality results - useful in all phases of incident response including identification, evaluation, assessment, and repair
  • Data can be exported into formats compatible with finite element analysis, 3D drafting programs or 3D printing
  • Metrology
  • Damage assessment
  • Engineering analysis (FEA, residual strength)
