CQI certified inspectors, being well-trained experts, have extensive expertise in the aboveground storage tank sector. This enables us to provide our clients with comprehensive code compliance.

CQI provides several types of surveys on above ground storage tanks. As part of inspections, physical surveys are performed externally to investigate for rigid tilting of the tank structure. Internally, investigations are conducted during out-of service inspections to quantify edge settlement and other floor depressions.

We also provide physical shell surveys to determine plumb and roundness of the tank shell.

Our non-destructive testing department is qualified to provide testing requirements in accordance with API Specifications. Inspections also include in-service and out of service checks of the following:

  • External shell inspection
  • Shell appurtenances, manways, nozzles, manifolds, heaters, mixers
  • Internal inspection
  • Roof and roof appurtenances
  • Tank floor integrity
  • Astral thickness determination
