Geometric Surveys
Staig & Smith have been engaged to check tank circularity for out of round distortion of fuel storage tanks. This work is easily carried out using reflectorless technology to survey the surface of the tank from a series of connected survey marks (traverse) surrounding the tanks.
The results of the survey can generate a three dimensional model of the tank and a cross-section generated at any level through the tank. Our 12d software allows a true circle to be arrived at as a best fit to the shape of the tank and deviations of the tank wall from this circle to then be represented in plan format..
Repeat surveys from the previously established traverse can allow for monitoring of tanks over their service lifetime. Trends such as tank subsidence may be interpreted from the results.
Reflectorless technology has greatly improved the ability to measure distances to discrete points and allows increased efficiencies and accuracy for industrial applications.
