Taking LiDAR laser Scanning Subsea – Ultra High Resolution Mapping and other real world applications.  Adam Lowry, 3D at Depth

Subsea laser scanning using Light Detection and Ranging (LiDAR) technology is changing the way we collect and interpret subsea spatial data.  A Subsea LiDAR laser collects 40,000 data points a second at ranges of up to 40m providing unparalleled accuracy and resolution in water depths of up to 4000m.   Used to acquire 3D models of structures and natural features, LiDAR and has become the industry standard terrestrial and airborne survey technology.  Hear how this technology is now regularly being used subsea.

Recent LiDAR developments have been to use the subsea point cloud data to 3D print damaged subsea parts at 1:1 scale, 3D visualisation of subsea infrastructure using VR technology and the launch of a tightly coupled “Dynamic” Subsea LiDAR mobile mapping solution integrating an INS & DVL. Projects to date have included 200+ spool metrologies, pipeline damage, pipeline oos & curvature, scour quantification, subsea structure movement, scientific seafloor mapping and subsea dimensional control.  3D at Depth were also recently announced as a technology partner to laser scan the wreck of the Titanic.

A HUGIN Case Study: Discovering Surprises.  Atle Gran, Kongsberg

Recently Kongsberg Maritime undertook an environmental survey in Norway close to where the HUGINs are built. Conducted on behalf of the local government, the aim was to collect seabed information and detail disused fishing equipment around a national park.

The AUV was equipped with HISAS, EM2040 and colour still image camera. It completed 4 dives over 2 days collecting bathymetry, seabed imagery and photographs. This presentation will discuss the vehicle configuration, mission concept and plans, along with presenting some surprising results and discoveries.
