Damage survey with 3D laser scan

The 3D laser scan technique used for a number of retrofits and conversions has been also successfully used to assess the extent of structural damages and the energy absorption in case of collisions and other circumstances. The picture shows the point cloud of a ship which capsized in drydock due to a failure of the side bottom blocks and this representation was used to assess the grounding reaction force which was necessary to design suitable anticapsizing devices and to refloating operations.
