APPLICATION 83 · STORAGE TERMINALS, TANK FARMS & BULK HANDLING

Tank floors, shells, nozzles and appurtenances

Inspection of primary containment components for corrosion, cracking, deformation, leakage and service-related deterioration. Within liquid and bulk-material storage and transfer facilities where containment is business-critical, this asset can directly influence containment integrity, corrosion, settlement, transfer reliability and environmental protection. 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

Asset condition report, corrosion maps, thickness and settlement data, defect register, repair priorities and inspection recommendations.

Codes & standards

The activity may be planned and reported against the applicable provisions of API 650, API 620, API 653, API 575, API 651/652, API 579-1/ASME FFS-1, EEMUA 159 and statutory/client requirements. Final references and acceptance criteria remain subject to approved project and statutory requirements.
