Crack_Assessment

Key Advantages

Integrated Framework of Inspection and Assessment:

  • Critical feature sizes inform ILI data analysis
  • Cracking susceptibility studies focus data analysis and in field verification
  • Rapid identification of critical features
  • Optimized future inspection and repair plans
  • Guaranteed fracture mechanics expert input

Other service benefits:

  • Construction support to control contractor quality/delivery
  • Post-construction audit, ensuring future integrity
  • Possible cost-effective alternative to hydro-testing
  • Avoidance of post-weld heat treatment
  • Failure-investigation support
  • Understanding remnant life and life-extension opportunities

The Solution

Our integrated Crack Management Framework ensures that all parties work together to collect the best possible data and deliver useable assessment results.

Codes that we typically use include API 1176, API 579, BS 7910, CEPA Recommended Practices, NACE SP0204, API 1104, ASME B31.8S, API 1160, and BS 7608.

These capabilities also allow us to provide other support including:

Engineering critical assessment:

ROSEN performs engineering critical assessment (ECA) to determine the allowable sizes of flaws found in the welds of all types of structures, supporting the implementation of efficient welding procedures.

Fatigue crack growth analysis:

Our experienced specialists deliver fatigue crack growth analyses that take into account the nature of the cracking, the environment, the loading conditions (including any stress concentration from local geometry), and the materials to determine the safe remaining life of cracks in structures.

Failure investigation:

We can support operators with the investigation of crack-induced failures by determining the causes of failure and providing future mitigation strategies for safe operation.

Technology/Know how

ROSEN has a long-term track record in advanced crack assessment services in pipelines. Expertise in stress corrosion cracking, coatings, pipe manufacture, material behavior, fracture mechanics, inspection systems, sensor technology, non-destructive examination, data analysis, fatigue, risk, stress analysis and statistics are all brought together as required to support the production of a complete, detailed crack assessment.
