3D Laser Scanning
3D Laser Scanning is a fast, cost-effective method of tank strapping. It provides millions of data points for analysis, reporting, and creation of 3D models. The 3D model can be used to visualize future changes while the tank is still in service. Examples of future changes might be adding or modifying platforms, heating coils, or changes to a floating roof. These advantages give 3D scanning an edge over other surveying methods.
3D Laser Scanning produces a variety of reports:
High-accuracy gauge tables with alarm levels
Tank bottom slope analysis
Containment area analysis
Out of roundness analysis
Manual Strapping has been a popular tank calibration method for many decades. To manually strap a tank, a certified tape is wrapped around the tank. However, it is unable to match the speed an accuracy of 3D scanning and cannot generate the variety of reports for your records.
Electro-Optical Distance Ranging (EODR) is another basic surveying technique. In additional to determining layouts by triangulation, EODR can also measure the distance to the point being surveyed. While EODR was cutting edge in the 90s, replacing the Optical Reference Line method of the 80s, it has been eclipsed by 3D scanning with its capability of measuring millions of points.
