APPLICATION 41 · OFFSHORE, SUBSEA & COASTAL ENERGY

Platforms, jackets and topside structures

Condition assessment of structural members, welds, nodes, supports and topside equipment in offshore operating environments. Within offshore production, marine transfer and coastal energy infrastructure operating in demanding environmental conditions, this asset can directly influence fatigue, corrosion, difficult access, marine exposure and safe offshore operations. 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

  • Section loss, pitting and coating breakdown in exposed or water-trapping areas.
  • Fatigue or weld cracking at connections, nodes, attachments and load-transfer details.
  • Deformation, impact damage, loosened fasteners, foundation movement and local overstress.

How IAIS UAE may support

  • Review drawings, loads, modifications and previous findings to identify critical members and connections.
  • Perform close visual examination, dimensional surveys, thickness measurement, weld NDT and difficult-access inspection where justified.
  • Record severity and location systematically and provide evidence for engineering review, repair design and maintenance planning.
Outputs & Requirements

Typical outputs and applicable standards

Typical outputs

Structural condition report, member and connection register, annotated photographs, dimensional/thickness data and prioritised actions.

Codes & standards

The activity may be planned and reported against the applicable provisions of API offshore and pipeline practices, ISO 19900-series standards, DNV standards, ASME B31 series, ASTM and operator requirements. Final references and acceptance criteria remain subject to approved project and statutory requirements.
