Objective
Assess damage to underwater portion of the Costa Concordia during the salvage
operation. Produce point cloud model of the entire underwater portion of starboard hull.
Solution
ULS-500 operating in Profile mode was mounted to a pole and lowered into the water
from a survey boat. The scanner produced high resolution 3D point cloud models of the
damage.

15m hub to hub metrology completed in 20 minutes- 4 scans 3 of which were
redundant.
Compared to stationary laser scanner approach which took 6 hours
Operational in conditions where other systems couldn’t operate due to proximity
of ROV ranges to target.
Contactless method of performing metrologies
Real time 3D data in large volumes
Seabed profile
Inherent part of the delivery (3D point cloud).
Minimal Calibration
Auto-calibration, mechanical integration,...
Reduced operational vessel and ROV time!
What does this mean for operational efficiencies?
