Metrology & geometric measurement
Quantified deviation. Documented uncertainty. Subsea included.
We deliver quantitative comparison between observed and reference geometry — both for surface industrial assets and for immersed structures where conventional metrology is difficult or impossible. Every output carries an uncertainty figure: tolerance maps, deviation reports, traceable measurements an engineering quality team can act on.
What we do
Geometric comparison of a manufactured or installed structure against its CAD reference, with deviation maps and tolerance flagging.
Image-based metrology of immersed industrial structures — pipelines, jackets, port works — without divers or specialised metrology frames on the seabed.
Quantification of geometric drift on structures subject to wear, deformation, corrosion or environmental load, across successive surveys.
Every measurement comes with its uncertainty. We document acquisition conditions, calibration state and propagation of error.
Method
CAD model, nominal geometry, or earlier digital twin as baseline.
Photogrammetric or sensor-based 3D acquisition of the current state.
Registration, deviation computation, tolerance evaluation.
Deviation map, tolerance status, uncertainty figures.
Typical applications
Verifying produced parts and assemblies against engineering tolerances.
Spool metrology, pipeline dimensional control, harbour and offshore asset inspection.
Tracking geometric evolution of structures under operational load over time.
