Some brief case studies have been performed with this technology that may interest you:

a. An above ground storage tank 150-ft dia x 48-ft tall in Pittsburg, CA storing asphalt was being cleaned. A tear was identified along the shell and visual inspection of the 22 columns identified to be leaning by approximately 2-ft (pre-failure scenario). The column out of plumbness were accurately measured and the rafters were identified to be shifted over. The damage was likely caused by out of roundness and edge settlement. The 3D laser scanner was use to model the tank and determine appropriate repairs.

b. An above ground storage tank 120-ft dia x 48-ft tall in Bellingham, WA storing crude oil had noted seal failure of the secondary seal. Extensive rim space gaps were measured. The 3D scanner was used to verify if shell distortion (that could have been caused by settlement or additional weight added to the shell from recent dome roof installation) is present that may have caused floating roof damages

c. An above ground storage tank in Rocklin, CA storing gasoline fuel had noted shell distortion. There was particularly concern that a recent earthquake with an epicenter not too far away may have caused the damage (inspector noted that the damage may have already been present prior to the earthquake). The facility wanted to know if the distortion was caused by the earthquake and more importantly if it could impact the structural integrity of the tank. Limited data was taken with the 3D scanner. No significant distortion was noted.

d. An above ground storage tank in Salt Lake City had some notable roof damage caused by a failed floating suction conveyor system. The conveyor supports were the only thing in contact with the floating roof deck after the conveyor system and wheels corroded off. Deep gouges that eventually caused holes under the floating roof were identified. The 3D scanner was used to scan the floating roof deck to determine extent of distortion that may have been caused by the floating suction pushing against the floating roof deck.
