APPLICATION 36 · MARINE, SHIPPING & SHIPBUILDING

Propulsion and machinery components

NDT and materials assessment of accessible shafts, casings, welds and machinery components during maintenance and overhaul. 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.

Propulsion and machinery components

NDT and materials assessment of accessible shafts, casings, welds and machinery components during maintenance and overhaul.

Integrity Focus

Principal considerations and IAIS UAE support

Principal integrity considerations

  • Fatigue cracking, wear, erosion, fretting and surface damage in stressed components.
  • Misalignment, looseness, vibration-related deterioration and defects at shafts, casings, blades or attachments.
  • Material degradation or repair-related discontinuities that may affect safe and reliable operation.

How IAIS UAE may support

  • Select target areas using maintenance history, operating data, OEM guidance and known failure modes.
  • Coordinate cleaning, disassembly status and access, then apply visual, surface, ultrasonic or other suitable NDT.
  • Correlate inspection findings with condition-monitoring or maintenance observations when data are available.
Outputs & Requirements

Typical outputs and applicable standards

Typical outputs

Component-level NDT report, defect locations and sizing, photographic record, acceptance status and maintenance recommendations.

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.
