Mobile Subsea LiDAR – Applications and Opportunities
In 2014, 3D at Depth performed 13 subsea scanning measurements at a depth of 2500 meters in the Gulf of Mexico. This was the first time that laser scanning was implemented to support construction surveying and paved the way for an emerging market for underwater laser based remote sensing. Since that time, market adoption has accelerated and now subsea laser scanning has become a mainstream tool for many asset owners and environmental consulting companies. The market has matured – again following the terrestrial market by offering faster collection methodologies from moving platforms; ROV’s, AUV’s and boats.
The technology for collecting accurate mobile LiDAR involves a unique integration of hardware and software including INS, USBL (think underwater GPS), DVL (tracks the bottom) and the LiDAR system. This presentation will discuss the various components and application for a variety of application including seabed mapping, asset as-builts, harbor and dock inspection and ship wreck visualization.
The attendees should be able to determine the advantages of using subsea LiDAR for their projects, the challenges and approximate budgets for collection and processing.
