Total Train Performance Advisor

Extending Turbomachinery Equipment Peak Performance

The compressor maintenance model has evolved from reactive (fixing after failure) to preventive (scheduled maintenance), then to condition-based (based on equipment condition), and now to predictive maintenance (using digital twin and data analytics to predict condition). The Total Train Performance Advisor (TTPA) is crucial for modeling dynamic compressor behavior, enabling predictive maintenance.

TTPA excels in performance modeling and visualizations, aiding in the detection of issues like fouling. It is very useful to quantify and demonstrate the results of maintenance strategies, such as water injection, to maintain efficiency with the compressor and extend the period when the compressor operates at highest performance.

Total Train Performance Advisor (TTPA) quantifies the degradation of a turbomachinery train by comparing its current performance to that of an original, healthy machine. With its accurate performance modeling and easy-to-understand visualizations, TTPA helps your team make the right operating decisions for your critical turbomachinery trains and validate the results of the online maintenance actions being taken.

Sophisticated model generation and plant-wide scalability

TTPA consists of three calculation modules to support a wide-range of process applications:

A sophisticated mathematical model is generated for each type of equipment based on original equipment manufacturer (OEM)-supplied performance data.

Delivering the right information, at the right time, to the right people

TTPA calculates and displays easy-to-understand health parameters:

• Key Data Points
  Those that are critical to understanding the health of a compressor, such as compression ratio and efficiency deviation, are summarized in a simple graphical dashboard.
• Immediate Alerts
  Percent deviation indicators and configurable alarms immediately notify asset owners when asset performance degradation is detected.
• Process Stability Detection
  An algorithm helps improve data quality by executing calculations only when the process is at steady-state.
• Trending of Performance
  Trending of performance parameters over extended period allow to determine if gradual or sudden degradation occurred and correlate the performance to other operational or maintenance events.
• Detect Faulty Transmitter
  As thermodynamic performance calculations are based on the combination of multiple instrument measurements, TTPA help detects drifting or mis-calibrated transmitters, which may otherwise remain undetected.
• Cost Calculations
  Quantify the cost of the reduced performance in term of additional power required and related economic impact.
