ACFM Weld & Hull Crack Inspection — Marseille

Alternating Current Field Measurement (ACFM) detects and sizes surface-breaking cracks in steel through the coating, without the surface preparation magnetic particle inspection requires — well suited to in-water structural welds where grinding back to bare metal isn't practical. Every crack indication found is sized and mapped directly onto the vessel's 3D digital twin, alongside the video record of the read.

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 crack-sizing report with every indication mapped onto the 3D model, without stripping the coating.
