65% Reduction in Gas Compression System Trips
During the first 12 months of application we helped this customer to achieve:
of production loss avoidance
reduction in gas compression system trips
maintenance savings
threats to stable operations were identified
Typical examples of the types of issues that our data scientists helped to identify on this system:
- Detection of deteriorating temperature control valve performance in lube oil preventing HSE incident
- Dry gas seals – early detection of hanging seal faces
- Detection of thrust probe instrument drift
- Long term prediction for suction cooler fouling rate reducing production bottleneck
- Detection of high flare back pressure leading to higher primary seal back pressure
Prevention of dry gas seal failure
During daily analysis, OPEX’s data scientists identified an issue with the flow rates on the dry gas seals during the start-up of the HP compressor after a long period out of service. The offshore team was promptly notified of the situation and an intervention was carried out to rectify the issue.
Had the system continued to run, it could have led to seal damage, significant repair costs and potential production loss. The situation was magnified as the other HP compressor was out of service at the time.
The customer estimated that this single intervention had avoided 10 day's production loss.
