Turbines and Engines

Gas turbines and gas engines obtain accurate, actionable emissions data from your engines and turbines to go beyond simply conforming to reporting requirements and provide actionable insights and fuel cost savings.

Built on First Principle-modeling

WS.PEMS uses traceable physical relations to measure combustion products with models tailored to your specific equipment and circumstances. The software makes maximum use of the instrumentation already available in your turbine or engine control system. No retraining. Just physics.

Regulatory compliance

WS.PEMS is certified under EN 14181, US EPA 40 CFR Part 60 and 75 (PS16), and SN-CEN TS 17198:2018. The platform covers the full range of international requirements for gas turbines and combustion engines.

First Principle-modeling

The system combines energy and mass balances to calculate the exact conditions in each combustion zone that together governs emission formation and combustion efficiency.

Online data reconciliation

An online data reconciliation system runs continuously alongside the model. Input data errors or sensor failures are detected and, in most cases, corrected automatically. Where correction is not possible, the issue is flagged immediately.

Gas Turbines

Maximum use of your existing instrumentation

Each WS.PEMS solution is built on an extensive set of physical relations governing turbine operation, including energy and mass balances and equipment characteristics. It makes maximum use of instrumentation and sensors already available in your turbine control system.

The result is traceable, actionable emission data across all your gas turbines and other emission sources. This gives you the insights to optimize your operations and reach your net-zero objectives.

LNG Vessels & Engines

The same precision, adapted for marine engines

WS.PEMS applies the same first-principles approach used by energy producers and now makes it available to LNG vessels.

Energy and mass balances are calculated locally on individual components and globally across the entire gas engine system. By tapping into existing process and condition monitoring data we provide unparalleled levels of reliability, delivered without the need for onboard technicians.
