Saudi Aramco’s FF Concerns & Wish
List

Aramco’s Biggest FF Problems:
1. Investigating Plug-In and Snap-On Software
2. Reliability of Diagnostic Alerts
3. Contractor knowledge of Commissioning FF
Devices
4. Lack of True OpEx Saving Experience

Conclusion
• FF technology is the way to go.
• It would be a complete failure if FF-SIF
diagnostic alerts are not reliable.
• Can the black channel technology be
implemented for control instruments?
