Storage Tank Inspection, Audit, Calibration
 Storage tank inspection, audit, and calibration from G.I.T.O ensure the safety and integrity of your storage tanks.

Storage tanks are commonly built using steel. Hazardous materials stored under severe conditions of pressure and temperature aids in stress induced corrosion to the steel plates, joints and weld-structures, affecting the integrity of the tank structure and causing environmental contamination, leakages, material loss and in cases fire and explosions and eventually human fatalities. As a result, you need to maintain a strict regime of pro-active maintenance and inspection protocols to ensure the safety and reliability of your tanks. Our inspection, audit and calibration services help you to avoid disasters and ensure that your storage tanks meet all relevant regulations.

G.I.T.O provides accurate and detailed measurement and calibration of large petroleum, fuel, and chemical cargo storage tanks including shore tanks and ship tanks used for holding crude oil, refined petroleum products, LPG, LNG, and other wet or dry bulk cargoes.

The range of Tank Inspection services typically delivered by our team of API certified Inspectors are:
  • Full compliance to API 653;
  • Fully automated external thickness measurements.
  • Automated and detailed tank floor measurements.
  • 3D modeling of the complete tank including the floor and its shell.
  • Hydro test.
  • Full range of Advanced Non-destructive Testing to complement integrity of tank structure.
  • Identification plate stamping and adjustment.
  • Compliance to international welding techniques.
  • Leak tracing.
  • Tank Shell assessment.
  • Roundness and Plumpness checks.
  • Tank Settlement Survey.
Storage tank calibration:
  • Horizontal and Vertical Land Tanks Calibration
  • Internal and external tank calibration by EODR (Electro-Optical Distance Ranging)
  • Pipeline Volume Calculations
  • Custody Transfer Systems (CTS)
  • Ship and Barge Tank Volume Calculations
Petroleum and chemical storage tanks calibrated:
  • Vertical Tanks
  • Horizontal Tanks
  • Spherical Tanks
  • Cylindrical Tanks
  • Double-wall Tanks
  • Fixed Roof Tanks
  • Floating Roof Tanks
  • Domed Roof Tanks
  • Conical Roof Tanks

Measurements include detailed assessments of wall verticality roundness and shape, along with roof & floor profiles. Tank calibrations are conducted to the exacting requirements of the appropriate international standards published by the International Standards Organization (ISO) or by the American Petroleum Institute (API). Detailed volumetric tables are compiled for each tank and can be formatted according to the client’s requirements. Comprehensive tables can incorporate any standard units of measure for size, volume or both.
