Choosing the right engine for a gas compression site is an important step. However, reliably predicting engine performance and tracking key metrics is essential for operational success in today’s energy landscape. As sustainability becomes increasingly important, operators require a tool that provides site-specific performance estimates to select the most appropriate engine solutions. 

Gas Engine Rating Pro (GERP) has been the standard for engine installation management for two decades. While operating and regulatory environments continue to shift, GERP continues to deliver estimated data based on current site conditions which allows operators to make informed purchasing, operation and maintenance decisions. As GERP data enables companies to evaluate potential variations in site performance, it helps reduce operational variability.

With the addition of the Cat^® G3600 A4 Gen 2 engine, GERP includes performance data sheets for new units as well as retrofit upgrades of Gen 1 engines.

Detailed Estimates at Your Fingertips

GERP offers all the information needed to make informed decisions at the project site; performance summaries offer insights into site-specific capabilities regarding engine performance and emissions. These performance data sheets provide detailed estimates of fuel consumption, emissions, the cooling system and more.* The tool offers access to documentation that details coolant pump performance as well as general dimension drawings and also allows assumptions to be documented to empower continuous operational improvement. Need to dive deeper into engine installation challenges? GERP’s resource library provides quick answers to application, installation and operation questions.

Test Performance Scenarios Before Adjusting Your Engine

You can get a glimpse of how your engine will perform under specific site conditions with GERP’s fuel analysis. Input values can be changed to simulate the impact on performance. Before project information is finalized, information can be easily added to the evaluation to run scenarios to identify optimal settings for your project and avoid delays.

No Connection? No Problem

GERP Lite is a portable version available for sites with limited internet connectivity. It offers many of the core capabilities of the full GERP package, delivering performance and key data to make effective predictions—no matter the location.

A Perfect Pairing with Next-Generation Engines

GERP complements the Cat® G3600 A4 Gen 2 engine (or a Gen 1 retrofit) to capture and share performance metrics. GERP can also forecast more accurate emission estimates than predictions based solely on fuel consumption, which is increasingly important for operators.

Conclusion

GERP remains an essential tool for the new generation of Cat gas compression engines used for gas lift, gas gathering, wellhead gas compression, pipeline compression, storage, gathering and re-injection. GERP tracks operational and regulatory metrics and helps ensure optimal engine performance. Learn more here.
