WS.PEMS for

LNG Vessels & Engines

Obtain accurate emissions data for LNG vessels and engines and achieve compliance with international regulations with PEMS

Similar to gas turbines models WS.PEMS is using an extensive set of physical relations governing the operation of the gas engines. This includes energy and mass balances as well as equipment characteristics. The First Principle Model makes maximum use of the vast instrumentation available in the engine control system

What you receive

Compliance

WS.PEMS is in compliance with international regulations, including EN14181, US EPA 40 CFR Part 60 and 75 (PS16), and SN-CEN TS 17198:2018.

Optimization

Get comparable and actionable data from all your LNG vessels and other emission sources and use the data to optimize your operation and reduce emissions.

A First Principle Model

The model takes into consideration energy and mass balances, locally on individual equipment (turbocharger, engine) and globally across the entire gas engine. These balances are used to calculate the exact conditions in the combustion zones that in the end govern the emission formation and combustion efficiency. An online data reconciliation system ensures that input data errors or failures are detected and in most cases corrected, and if not, flagged.
