Anything 3D we love, especially when you combine above-water LiDAR and below-water Bathymetry into one seamless 3D model. This capability is changing how marine infrastructure projects are surveyed, visualised, and delivered.
Tailored Spatial Solutions recently delivered a combined Bathymetric and LiDAR 3D survey of the new barge ramp in Cairns for Brady Marine, with the goal of confirming dredging volumes and assessing design conformance across the site.
By integrating drone-based LiDAR (DJI) for detailed above-water elevation and NORBIT Subsea multibeam sonar for precise seabed mapping, the team produced a fully georeferenced 3D model that captured the entire ramp footprint, both above and below the waterline. GNSS verification was completed using Emlid for high positional confidence.
Tailored Spatial Solutions also operate a marine support arm, Tailored Marine Solutions, specialising in commercial diving, marine construction, and vessel support services across Northern Australia and PNG.
This integrated approach delivers:
Accurate post-dredge volume verification
Clear 3D visualisation of design conformance
Enhanced reporting and faster decision-making for stakeholders
Seismic Asia Pacific was proud to support this project with equipment and technical expertise. It is a strong example of how advanced spatial data and 3D visualisation are driving the next generation of marine infrastructure delivery. See some project photos below.
