| Abstract | A geothermal separator that experienced fatigue and corrosion fatigue cracking on the internal stand pipe attachments was subjected to an advanced engineering critical assessment including Finite Element stress analysis and vibration analysis to define the root cause of the cracking. The developed Finite Element model was used to analyse proposed mechanical arrangements to reduce the risk of cracking in future. Repair options were identified and a successful repair method was achieved. |
