Magnetic particle testing (MT) detects surface and near-surface cracking in ferromagnetic structures subject to fatigue or impact loading during operation. Penetrant testing (PT) reveals fine surface defects on components affected by wear, environmental exposure or operational stresses. 3D Magnetic Flux Leakage (3D MFL) maps surface and near-surface deterioration in ferromagnetic components exposed to operational loads.
Inspection and non-destructive testing (NDT)
Condition monitoring with NDT
Detect in-service corrosion, wear and damage to support safe operation and targeted maintenance
For operators responsible for structures, tanks, piping and other critical assets, limited insight into condition during operation creates uncertainty and risk. Ageing, corrosion, wall loss and cracking can develop unevenly and remain unnoticed until they affect safety, availability or compliance.
Tracking asset degradation during operation
In-service non-destructive testing provides a direct view of how assets change over time, identifying degradation where it matters most. Condition data supports targeted maintenance, clearer prioritisation and more reliable operation, helping operators avoid reactive repairs, unplanned stoppages and uncertainty about fitness for service. The service is part of our expertise area Inspection and non-destructive testing (NDT).
Challenges
When asset condition remains uncertain during operation, risk and inefficiency increase
Restricted access limits inspection coverage
Critical areas are located in confined, elevated or shielded positions that are difficult to reach during operation, leaving parts of the asset outside normal inspection routines.
Progressive wall thinning reduces structural margin
Corrosion-related wall loss develops gradually and may not be visible through spot checks, reducing remaining strength before intervention is triggered.
Service-induced damage evolves between inspections
Fatigue, wear and cracking can initiate and grow under operating loads between planned inspections, narrowing the window for preventive action.
Incomplete condition data weakens maintenance decisions
When degradation is uneven across components, limited or fragmented data makes it difficult to prioritise repairs, justify interventions or plan maintenance with confidence.
Benefits
Make confident maintenance decisions and avoid surprises
Earlier detection, fewer unplanned stoppages
In-service non-destructive testing reveals degradation before it affects safety or output, helping avoid sudden interruptions and reactive maintenance.
Targeted intervention, lower maintenance waste
Reliable condition data reveals exactly where corrosion, wall loss, or damage is most advanced, reducing unnecessary repairs and focusing effort where it delivers the most value.
Clear trends, more confident lifetime decisions
Documented changes in condition highlight how assets age, supporting well-timed repairs, safe life extension and long-term planning.
Extended reach, fuller understanding of asset health
NDT techniques and access solutions enable the assessment of areas that are normally out of reach, providing a more comprehensive and reliable view of the in-service condition.
