In-Water Ultrasonic Thickness (UT) Testing — Marseille

Ultrasonic thickness testing measures remaining steel plate thickness through the coating, without grinding a bare-metal spot — the standard method for tracking corrosion and wastage against a vessel's original scantlings. Every sounding we take is logged against its exact position, then pinned directly onto the vessel's 3D digital twin, so a thinning trend across a ballast tank or a boot-top run is visible as a map, not a table of coordinates someone has to mentally place.

Why it matters in Marseille

France's largest port, and home to DRASSM — France's national department for underwater archaeological research — reflecting the Mediterranean coast's density of documented ancient wreck sites nearby.

A major commercial port sitting alongside France's own underwater archaeology authority makes Marseille a genuine fit for both vessel/infrastructure survey work and non-invasive heritage-site documentation.

Deliverable

A UT sounding report with every reading pinned to its location on the 3D model, plus the raw data set.
