Achieve and Maintain Optimum Equipment Performance

AMS Performance Advisor calculates thermodynamic-based equipment performance using industry standard ASME PTC performance calculation techniques to provide deviation from design diagnostics on your critical machinery, including turbines, compressors, boilers, and other production assets. Specific key performance indicators combined with clear graphical operating plots show exactly where the equipment is currently operating versus expected or design condition. Tuning over the first twelve months is included with AMS Performance Advisor and executed by thermodynamic experts to ensure system feedback is credible.

AMS Performance Advisor provides calculated information for the following key equipment types:

  • Compressor — Centrifugal
  • Compressor — Reciprocating
  • Gas Turbine
  • Steam Turbine
  • Boiler
  • Fired Heater / Furnace
  • HRSG
  • Condenser — Air Cooled
  • Condenser — Water Cooled
  • Large Pump
  • Large Fan
  • Heat Exchanger
  • Cooling Tower

Real-Time Equipment Performance Monitoring

The real-time information available from AMS Performance Advisor helps you pinpoint opportunities for performance improvement that would otherwise go unnoticed. Differentiating features add value and knowledge to equipment operation.

  • Data connectivity to any historian or DCS regardless of vendor
  • Intuitive graphical presentation clearly displays current operating point compared to design criteria
  • Integration of protection, prediction, and performance information
  • Quarterly tuning of system through first year to ensure credible feedback

Flexible Data Connectivity

AMS Performance Advisor receives measurement input data from existing field instrumentation or from manually-entered values. Data can be connected to any manufacturer’s DCS or data historian. This flexibility means that plants with multiple sources of input data and information systems can unify their performance calculations in a single, centralized location.

Leverages Open Protocols
Data connectivity methods are based around industry-standard OPC or OLE (Object Linking and Embedding) for process control. Popular plant historians, such as OSI® PI® are also supported.

Availability of Data Values
AMS Performance Advisor can support data that is entered several times per shift rather than continuously measured. The manual data is submitted directly into the DCS or historian where AMS Performance Advisor will access using the same method as the continuously measured values.

Intuitive User Interface

Graphical displays can provide key information to guide decisions towards managing “controllable losses” by operating towards optimal targets.

AMS® Suite: Asset Graphics presents a graphical interface for protection, prediction, and performance diagnostics utilizing the latest approaches for information clarity:

  • Gray screen backgrounds
  • Color only when abnormal
  • Touch-screen navigation
  • Single-equipment layer
  • Status safeguards

Single Equipment Layer
All equipment information is available one level deep from the home navigation page. A tab for performance shows all relevant information.

Multiple Users
AMS Performance Advisor communicates specific diagnostics aligned to plant roles.

  • Operators obtain feedback on set point changes with plots that utilize colored regions.
  • Maintenance resources can prioritize planned activities.
  • Process Engineers can visually isolate questionable measurements in the process flow and their influence on the module calculations.

Credible System Feedback

  • AMS Performance Advisor includes features that are designed to handle common challenges to producing credible system feedback. Key features include data validation and manipulation, accuracy of results, and analog input filtering.
  • Input Data Validation
    AMS Performance Advisor evaluates the quality of DCS/historian input signals and uses them to provide status, augment data, and issue alerts or warnings. Since equipment performance calculations are measured to tenths of a percent, module input measurements must be accurate. AMS Performance Advisor ensures the accuracy of these calculations and delivers reliable results.
  • Analog Input Filtering
    Fidelity of AMS Performance Advisor is ensured through built-in analog input filtering and validation techniques. Analog signals may have a small degree of smoothing applied inside AMS Performance Advisor to analysis, particularly when noisy data is present. A reported ‘poor’ or ‘suspect’ status of any input or substituted value is made visible through AMS Asset Graphics in the Process Flow tab, delivering an early warning mechanism for problematic data connectivity or measurement devices.

Configurations That You Can Trust

While spreadsheet applications have been used in the past for equipment performance calculations, they have proven to be cumbersome and inaccurate. AMS Performance Advisor accommodates real-life complexities while providing credible results that you can trust. Compared to do-it-yourself spreadsheets, AMS Performance Advisor provides overwhelming benefits.

  • Easier comparison of reference operation at “standard conditions”
  • Non-cumbersome data cleaning and validation techniques
  • Seasonal effects that are easily identified
  • Model data smoothing to help you understand underlying performance trends
  • Easy-to-use detailed graphical interface and historian capabilities that interface with external data sources
  • Consistent model approach for similar units on a site-wide and organization-wide basis
