Case Study – Weekly Level 1-2 FFS/Repairs
Becht handles weekly FFS evaluations for the past 8+ years for an onshore facility in Iraq. If FFS fails, Becht can:
- De-rate the vessel;
- Design a repair;
- Proceed to level 3 FFS.
Becht evaluations also have covered these aspects:
- Tankage
- Expansion joints
- Heat exchanger
- Civil/structural
Pressure Vessel Design Calculations
- Min. Required Thickness
- Max. Allowable Working Pressure (MAWP)
Fitness for Service (API 579-1/ASME FFS-1)
- Uses Becht proprietary software
- Level 1 and Level 2 analysis
- General metal loss/local metal loss
- Pass
- Fail – Repair or de-rate MAWP
The FFS assessments have enabled the facility to plan and prioritize vessel inspections, repairs, and replacements to keep running longer and reduce downtime when it is necessary.
