Sea Wall & Quay Sheet Pile 3D Mapping — Marseille

A harbor retaining wall or sheet-pile quay degrades slowly and mostly out of sight below the waterline — which is exactly why it tends to get inspected reactively, after a visible problem shows up onshore. We produce a full photogrammetric 3D model of the submerged structure, giving engineers a real baseline to track bowing, corrosion holes, and concrete erosion against on each subsequent survey, rather than relying on diver notes that are hard to compare year to year.

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 georeferenced 3D model of the structure, with measurable deflection and erosion data comparable across surveys.
