Pre- & Post-Dredging Seabed 3D Clearance — Marseille

A dredging contract usually turns on two questions afterward: was every hazard actually removed, and how much material actually moved. We produce a full 3D bathymetric and visual survey before and after the dredging campaign, giving the contractor and the client a directly comparable before-and-after record — hazard clearance proven visually, volume clearance proven bathymetrically, not asserted.

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 before-and-after 3D survey pair, quantifying dredge volume and confirming hazard clearance.
