APPLICATION 39 · MARINE, SHIPPING & SHIPBUILDING

New-build and repair welds

Quality verification of fabrication and repair welds using approved procedures and acceptance criteria. Within vessels, shipyards and port assets subject to seawater exposure, dynamic loading and class-controlled maintenance, this asset can directly influence structural integrity, watertight containment, repair quality and operational readiness. 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

  • Material or traceability discrepancies, dimensional nonconformance and manufacturing defects.
  • Weld discontinuities, heat-treatment or hardness concerns, repair quality and incomplete process records.
  • Damage introduced during forming, machining, assembly, testing, preservation or handling.

How IAIS UAE may support

  • Prepare inspection and test surveillance around approved drawings, specifications, ITP hold points and acceptance criteria.
  • Verify materials, traceability, fit-up, welding, NDT, dimensions, heat treatment, pressure testing and documentation as applicable.
  • Raise and close observations or nonconformities and confirm the release dossier reflects the accepted manufacturing status.
Outputs & Requirements

Typical outputs and applicable standards

Typical outputs

Inspection release notes, surveillance reports, NDT and dimensional records, traceability review, punch list and final dossier status.

Codes & standards

The activity may be planned and reported against the applicable provisions of applicable IMO and flag requirements, IACS/classification-society rules, ISO 9712, AWS, ASTM, EN and owner specifications. Final references and acceptance criteria remain subject to approved project and statutory requirements.
