What we do

As-built vs CAD comparison

Geometric comparison of a manufactured or installed structure against its CAD reference, with deviation maps and tolerance flagging.

Subsea metrology

Image-based metrology of immersed industrial structures — pipelines, jackets, port works — without divers or specialised metrology frames on the seabed.

Deviation analysis over time

Quantification of geometric drift on structures subject to wear, deformation, corrosion or environmental load, across successive surveys.

Uncertainty reporting

Every measurement comes with its uncertainty. We document acquisition conditions, calibration state and propagation of error.

Method

01
Reference

CAD model, nominal geometry, or earlier digital twin as baseline.

02
Capture

Photogrammetric or sensor-based 3D acquisition of the current state.

03
Compare

Registration, deviation computation, tolerance evaluation.

04
Report

Deviation map, tolerance status, uncertainty figures.

Typical applications

Manufacturing control

Verifying produced parts and assemblies against engineering tolerances.

Subsea structure metrology

Spool metrology, pipeline dimensional control, harbour and offshore asset inspection.

Structural monitoring

Tracking geometric evolution of structures under operational load over time.
