Storage tanks are used to store different types of hazardous materials which can sometimes cause risks to human health and safety; and may endanger the surrounding environment. Spills of hazardous substances into the soil can lead into costly downtime and decontamination process. Periodic tank inspection surveys are very important and can prevent such risks. Tank calibration surveys are also mandatory by many national and international codes and standards.
Twozan Surveys offer tank calibration services to tank farm operators to ensure that their storage tanks are in compliance with local and international regulations as well as relevant codes and standards. Services include but not limited to the following:
Foundation and settlement evaluation
Shell evaluation measurement
Bottom evaluation measurement
Verticality evaluation measurement
Tank volume calibration
Visual inspection with 360° panoramic images
Survey of new repairs and installations
3D CAD modeling
Twozan Surveys utilize state of the art technology to carry out these surveys. We employ the latest technology in 3D laser scanning and spatial imaging as a Non Destructive Testing (NDT) method when performing these surveys. It provides the most accurate measurement and generates rich datasets. Based on the survey data, we can generate the required survey reports reflecting the existing conditions of the storage tanks at various storage levels.
