APPLICATION 07 · OIL, GAS & LNG

Aboveground storage tanks

Integrity support for tank floors, shells, roofs, nozzles, foundations and associated components during in-service and out-of-service programmes. Within hydrocarbon production, processing, transportation and export operations, this asset can directly influence pressure containment, corrosion control, process safety and production continuity. A focused integrity programme should therefore connect the design basis, materials, service history, previous findings and current operating condition, so that inspection effort is directed to credible damage locations and produces information that supports practical maintenance decisions.

Integrity Focus

Principal considerations and IAIS UAE support

Principal integrity considerations

  • Floor or shell corrosion, pitting, product-side attack and external environmental degradation.
  • Weld cracking, distortion, roof or internal-component deterioration and leakage pathways.
  • Foundation movement, settlement, coating or lining breakdown and nozzle or appurtenance damage.

How IAIS UAE may support

  • Plan in-service or out-of-service coverage from design, stored medium, history and governing inspection requirements.
  • Apply visual examination, thickness mapping, floor or weld screening, dimensional surveys and targeted NDT as appropriate.
  • Correlate findings with previous data and support repair definition, interval review and return-to-service documentation.
Outputs & Requirements

Typical outputs and applicable standards

Typical outputs
