The marine and offshore industries operate in some of the most demanding environments in the world. Saltwater corrosion, heavy loading, fatigue, vibration and continuous operation place enormous demands on vessels, offshore structures and port infrastructure.

Whether constructing new assets, maintaining existing infrastructure, preparing equipment for transportation or extending the life of ageing structures, reliable inspection is essential to maintaining safety, compliance and operational performance.

At Libellum, we provide independent inspection, advanced non-destructive testing (NDT) and quality assurance services across the marine, offshore and port sectors. Our experienced inspectors help clients make informed engineering decisions, maintain compliance and protect the integrity of critical assets throughout their operational life.

From fabrication workshops to dry docks, quaysides, offshore platforms and renewable energy projects, our experienced personnel deliver practical, professional support wherever it is required.

Marine Inspection Services

Our inspectors support every stage of a marine asset's lifecycle.

  • Eddy Current Testing
  • Corrosion mapping
  • Thickness measurement surveys
  • Weld inspection
  • Structural integrity assessments
  • Pressure system inspection
  • Fabrication quality surveillance
  • Repair verification
  • Vendor inspection
  • Project quality assurance
  • Inspection reporting
  • Technical review

Typical inspection areas include hull structures, ballast systems, deck equipment, cranes, lifting points, pressure systems, fabricated pipework, structural repairs and critical welded connections.


Offshore Inspection Services

Operating offshore demands inspection services that are technically robust, responsive and delivered with safety at the forefront.

Libellum supports offshore operators across oil & gas, offshore wind, marine construction and renewable energy projects with inspection services designed to minimise operational disruption while maintaining confidence in asset integrity.

Our offshore capabilities include:

  • Structural inspection
  • Weld integrity assessment
  • Corrosion monitoring
  • Thickness measurement
  • Pressure system inspection
  • Crane and lifting structure inspection
  • Shutdown support
  • Vendor surveillance
  • Asset integrity programmes
  • Quality assurance support
  • Inspection reporting
  • Technical consultancy

Whether supporting planned maintenance campaigns, fabrication projects or urgent operational requirements, our inspectors integrate seamlessly into project teams to deliver reliable, independent inspection services.


Sea Fastening Inspection

The safe transportation of large fabricated structures is critical to successful marine and offshore projects.

Libellum provides independent inspection of sea fastening arrangements to verify that fabricated securing systems have been manufactured and installed in accordance with approved drawings, project specifications and client requirements before transportation.

Our inspectors verify:

  • Weld quality
  • Structural integrity
  • Dimensional compliance
  • Material identification where required
  • Installation quality
  • Overall condition prior to mobilisation

Sea fastening inspections are commonly undertaken before transporting offshore modules, subsea structures, fabricated steelwork, renewable energy components, pressure equipment and heavy engineering assemblies.

Independent verification provides confidence that assets are securely prepared for transportation, reducing risk before they leave the quayside.
