Summary

Assessment the remaining fatigue life of offshore assets

Scope of work
  • Mooring system robustness check (Strength & Fatigue TT / ITB / OPB)
  • Application for spread mooring or Turret system
  • Chain corrosion extrapolation
  • Local model of the chain (including corrosion / pitting) to get the SCF
  • Mooring Repair plan to get the additional design life
  • Development of a repair procedures (spare part report)
  • Spectral Fatigue Analysis of FPSO hull for life extension
  • Jacket Life Extension (Strength & Fatigue)
  • Umbilical / Cable and Pipeline Life Extension (Strength & Fatigue)
