Pre- & Post-Dredging Seabed 3D Clearance

Before-and-after 3D bathymetric and visual maps of shipping lanes or marinas, proving hazard removal and volume clearance for dredging contractors.

Overview

What This Involves

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.

Method

How It's Done

01

Pre-dredge 3D bathymetric and visual survey establishing the baseline

02

Hazard and obstruction locations logged against the survey grid

03

Post-dredge survey run to the same grid and datum

04

Before/after comparison quantifying volume moved and confirming hazard clearance

Output

Deliverable

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

Fit

Who It's For

Dredging contractors and port authorities needing an independent, comparable clearance record.
