APPLICATION 82 · STORAGE TERMINALS, TANK FARMS & BULK HANDLING

Fixed and floating roofs

Condition assessment of roof plates, pontoons, seals, supports, drainage systems and associated components where accessible. 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

  • Corrosion, wear, cracking or deterioration associated with the operating environment.
  • Damage at welds, connections, supports and mechanically or thermally stressed locations.
  • Coating breakdown, deformation and defects arising from ageing, modification or maintenance history.

How IAIS UAE may support

  • Review available design, service and inspection information to define critical areas and acceptance requirements.
  • Apply a suitable combination of visual, dimensional, NDT, materials and specialised-access methods within the approved scope.
  • Assess and report findings consistently to support repair, monitoring, engineering review and maintenance prioritisation.
Outputs & Requirements

Typical outputs and applicable standards

Typical outputs

Inspection report, asset register, calibrated measurements, NDT records, photographs, anomaly ranking and recommended actions.

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.
