Engineering Critical Assessment

ECA analysis to develop girth weld flaw acceptance criteria in accordance with the following codes:

  • API 1104 – Appendix A (19th and 20th editions)
  • DNV OS F101
  • DNV RP F108
  • BS 7910
  • API 579

Critical components assessed:

  • Flow lines including high pressure and high temperature (HP/HT)
  • Risers (SCRs, TTRs, hybrid, etc.)
  • Export pipelines

Pipeline installation methods include:

  • S-Lay
  • J-Lay
  • Reeled installation

Special ECA considerations:

  • Analysis, qualification and validation requirements for strain-based design, including reeling
  • Sour service ECA analysis and validation testing
