key advantages

  • Stress based assessment  reflecting the actual severity of deformations.
  • Based on ROSEN high-resolution ILI tool data – the highest accuracy in the market.
  • Fast pre-assessment and prioritization through calculation of stress concentration factors (SCF).
  • Detailed remaining life analyses for high priority features (e.g. according to API 579 Level 3).
  • Fast delivery – streamlined process through close co-operation of ILI and integrity assessment provider.     

The Solution

ROSEN provides a stress based assessment for deformations of the pipeline wall.  The assessment basis are geometry data recorded with ROSEN high resolution geometry tools. They combine traditional mechanical caliper arms with a touchless, electronic measurement system covering 100% of the pipeline circumference. This way the contours of deformations are captured with utmost precision – a prerequisite for a high-end FFS assessment.
Through stress concentrations factors (SCF) the features are prioritized for subsequent conduction  of remaining life analysis taking into account pipeline material properties and operating pressure cycles.
