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

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 Rotterdam

Europe's largest port by cargo volume, with an extensive network of quay walls, sheet-pile berths, bridges, and subsea pipelines built up over more than a century of expansion.

The sheer scale and age of Rotterdam's submerged infrastructure — quay walls, bridge substructures, pipeline routes — makes ongoing 3D condition survey a genuine, standing requirement rather than a novelty.

Deliverable

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