APPLICATION 45 · OFFSHORE, SUBSEA & COASTAL ENERGY

Mooring and lifting systems

Condition assessment of accessible chains, wire ropes, padeyes, lifting points and structural connections under approved procedures. 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

  • Fatigue cracking, wear, corrosion and deformation of load-bearing components.
  • Damage at welds, padeyes, pins, sheaves, ropes, chains, attachments and foundations.
  • Misalignment, looseness and deterioration arising from repeated or overload service.

How IAIS UAE may support

  • Define critical components and acceptance criteria from equipment records, duty, statutory requirements and approved procedures.
  • Apply visual, dimensional and targeted NDT methods to accessible load-path components and connections.
  • Support authorised proof/load-test witnessing or post-repair verification only where included in the approved scope.
Outputs & Requirements

Typical outputs and applicable standards

Typical outputs

Examination records, component register, NDT results, photographs, nonconformity list and recommendations for repair or further assessment.

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.
