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.

G.I.T.O Pipeline Services has years of experience in all aspects of pipeline inspection and assessment. Our team includes engineers, and certified inspectors from a variety of technical disciplines including petroleum engineering, corrosion, mechanical engineering metallurgy and materials science.
More and more on- and offshore pipeline systems must traverse remote regions with extreme terrains or harsh environments. Transporting oil or gas cost-effectively, safely and responsibly to consumers, via what is often an ageing pipeline infrastructure, is not a simple task, particularly when pipelines cross territories that are subject to different regulatory regimes and requirements.
Soil erosion, seismic activity, extreme free spans, ground movement and use of materials in corrosive environments – we can help overcome these and other barriers.
Our transparent approach to verification, certification, AND quality surveillance enables operators to reduce risk, to ensure a successful project outcome.

G.I.T.O offers an array of pipeline inspection services including the following:

  • Gas Pipeline Inspection
  • Pipeline Explosion inspection
  • Pipeline Evaluation
  • Pipeline Coating Assessment
  • Pipeline Damage Inspection
  • Slope stability analyses
  • Flow analyses of failed soil
  • Pipe soil interaction studies
  • Network capacity assessment
  • Pipe reeling
  • Pipe snaking

Our technicians are all trained in pipeline specific techniques and field conditions. Our reporting system is unique to each customer and developed to meet the individual needs of your program.


Corrosion services from G.I.T.O prevent catastrophic failure and maintain safe, reliable operation of your industrial equipment.

Surface Iron/Discharge and Manifold Equipment

G.I.T.O is one of the leading providers of this service in various countries throughout the world. G.I.T.O’ s professional inspection team has the experience to ensure the required safety and quality outcomes for all our customers .This provides our customers with the peace of mind that their equipment is in good hands and will be returned in perfect working condition in a timely manner.

G.I.T.O Surface Iron/Discharge Manifold Equipment Inspection services includes:

Visual inspections are performed to insure the equipment has not been damaged in transit. Any damage is immediately reported and repair work can be done post approval from our customer.

The discharge manifold equipment is now dismantled, cleaned by power tools and washed in De-greaser, inspected for wear, corrosion and worn out parts. Seals, O Rings, segments, Retainer Rings and plugs are all examined for damage and wear.

Ultra Sonic Wall Thickness measurements are performed in accordance with customer’s specifications and the DME manufacturer. Any reading below the specified minimum will result in rejection of the equipment.

Dimensional Measurements are taken on areas of the equipment that are susceptible to wear, to ensure wear is not below Minimum Dimensions.

Non-Destructive Inspection & Testing NDT is performed to ensure the equipment has not been over worked or placed under stress. Magnetic Particle/ Fluorescent and Black & White Inspection for ferromagnetic equipment parts and Dye Penetrant Inspection for the non-magnetic equipment is tested to ensure against defects.

After the equipment has been pressure tested, it will be spray primed and painted to our customer’s specifications. After drying the equipment is then ID Tagged with metal bands for traceability and identification. Final reports and test charts are issued to the customer to complete the final process.

(When all examinations are complete the equipment is then re-assembled, cleaned and flushed to remove any debris trapped by re-assembly and greasing. Finally pressure is tested to the customer’s specific pressure ratings. This is to simulate the maximum pressure the equipment will be subjected to during field operations. This significantly reduces the chance of failure.
