The Research Application of 3D Laser Scanning Technology in the Deformation Detection of Large Cylindrical Oil Tank

Abstract

In order to ensure the safety in using a large cylindrical storage tank, it is necessary to regularly detect its deformation. The traditional total station method has high accuracy in determining the deformation, however, it has a low measurement efficiency. Long-term observation means, there are more risks in the petrochemical plant, therefore, this paper proposes the usage of the 3D laser scanner, replacing the traditional total station to determine the deformation of a large cylindrical storage tank. The Matlab program, is compiled to calculate the point cloud data, while the tank deformation is analyzed from two different points which are, the local concave convex degree and the ovality degree. It is concluded that, the difference between the data obtained by 3D laser scanning, and total station is within the range of oil tank deformation limit, therefore, 3D laser scanner can be used for oil tank deformation detection.

UAS Photogrammetry and TLS Technology: A Novel Approach to Predictive Maintenance in Industrial Tank Systems

“…For example, ref. [1] applied TLS technology to generate high-resolution 3D models of a cylindrical oil tank and detect deformations in its shell. Similarly, ref.…”

“…Storage tanks play a crucial role in various industries, such as the oil, chemical, food, and power generation industries, by allowing the collection, regulation, and distribution of large volumes of liquids and gases [1]. However, due to their large dimensions, the nature of the stored products, and the operating conditions to which they are subjected, these assets are exposed to various adverse situations that cause damage or deterioration that can compromise their structural integrity and functionality [2].…”
