Case Study: GMAP Scrubber

Posted on:

CADSurvtech was hired to scan a GMAP Scrubber system located at a large phosphate facility. The objective was to scan a large overhead piping duct which led into the main facility. The scans were performed from an upper platform with only ladder access. Survtech utilized the FARO Focus 3D and its compact nature to acquire the scan information. The upper scans were registered with the lower portion by way of cloud to cloud registration. The location of additional project items were required as well; such as steel beams, pump and valve locations, and the radius of the main scrubber tank were all acquired. As complex as the requirements were; Survtech was able to acquire all needed information in a days work.

Case Study: Tank Deformation

This 3D Laser Scan of a Tank Accurately Documents the Degree of Deformation

Survtech was hired to scan a 300k gallon petroleum tank that had experienced a release valve failure, which in turn caused structural failure. The damage occurred when the tank was being emptied, and the release valve failed to open. Resulting in a vacuum in the tank which crumpled inward from the pressure, creating several large dents. The client needed to know if the tank was salvageable or if they needed to replace the entire tank. Survtech was responsible for scanning the tank, and creating a 3 dimensional nurbs surface of the tank. This data was then imported into a Finite Analysis program to determine the extent of damage.
