APPLICATION 34 · MARINE, SHIPPING & SHIPBUILDING

Ballast, cargo and void spaces

Close-up inspection of internal spaces for corrosion, coating breakdown, deformation, cracking and other structural concerns. 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

  • General wastage, pitting, grooving and coating breakdown in seawater or cargo-exposed spaces.
  • Buckling, deformation, impact damage and fatigue cracking in primary structural details.
  • Leakage or deterioration at boundaries, penetrations, welds and inaccessible structural members.

How IAIS UAE may support

  • Align survey areas with vessel records, class/owner requirements, previous thickness data and known critical locations.
  • Conduct close-up visual examination, thickness measurement and targeted weld or surface NDT with suitable access and preparation.
  • Compare results against allowable criteria and identify areas requiring repair, further gauging or specialist assessment.
Outputs & Requirements

Typical outputs and applicable standards

Typical outputs

Survey report, thickness measurement record, structural sketches, photographs, suspect-area register and repair 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.
