APPLICATION 35 · MARINE, SHIPPING & SHIPBUILDING

Piping and pressure systems

Integrity support for onboard piping, vessels, valves and connected pressure components during service, repair or dry-docking. 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

  • Internal and external corrosion, localised pitting, erosion or flow-assisted wall loss.
  • Weld or heat-affected-zone cracking, fatigue at branches and vibration-sensitive locations.
  • Coating or insulation breakdown, support deterioration, displacement and mechanical damage.

How IAIS UAE may support

  • Review line class, design and operating history to establish damage mechanisms and critical inspection locations.
  • Combine visual examination, thickness mapping, weld NDT, corrosion screening and specialised access as justified by the scope.
  • Evaluate indications, establish condition trends and support repair, monitoring or engineering-assessment decisions.
Outputs & Requirements

Typical outputs and applicable standards

Typical outputs

Inspection plan, traceable location register, calibrated readings and images, indication assessment, marked-up drawings and prioritised 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.
