Marine Services :: 3D Scanning

Laser scanning develops a very dense point cloud of an upland project area that can be used to create detailed, high-resolution 3D digital models. The abundance of data collected by this technology, and the ability to integrate the results with other survey information, makes laser scanning a cost-effective tool for a variety of applications, including structure assessment, utility inventory, and delineating difficult slopes and topography.

Vessel-based laser scanning can be used concurrently with hydrographic surveying operations to allow DEA to dynamically map above-water surfaces, including waterfront infrastructure, such as terminal and shoreline outlines, and vertical clearances for bridges and overhead transmission lines.

Obtaining multibeam bathymetry alongside scan data enables DEA to collect a very dense data set — from the seafloor to the top of the bank — in one pass. Combining mobile laser scanning with multibeam hydrography enables the generation of a fully integrated hydrographic and topographic digital terrain model.

DEA also utilizes static topographic scanners as well as truck-mounted mobile terrestrial systems for high-definition 3D laser scanning, asset management, and infrastructure mapping from land-based perspectives.

BlueView Stationary Scanner
DEA owns and operates a Teledyne BlueView BV5000-1350 sonar for underwater 3D scanning efforts. This system captures high-resolution 360-degree scans at ranges up to 30 meters from its mounting point, which can be either a fixed tripod or a maneuverable ROV.

Utilizing a BlueView system allows DEA to acquire detailed point cloud data in hard-to-access locations and allows data collection under overhangs or other obstructions that block conventional surface-mounted sonar systems. This enables DEA to inspect draft tubes and intakes as well as map undercut or other areas where multibeam sonars from surface vessels cannot map.
