Accelerate Marine Emissions Compliance with CATAGEN

CATAGEN enables marine OEMs to meet global emissions legislation faster, with higher accuracy, and greater flexibility using our patented OMEGA technology.

Designed to replicate engine flow rates, temperatures, and gas compositions across any engine type, The OMEGA provides full-scale catalyst ageing without the need for combustion, fuel use, or engine wear.

We use our proprietary toolset (that has unrivalled levels of repeatability, accuracy and control globally) to provide our partners with unique data so they can develop their vehicles with the best calibration and thus optimised emissions.

Why Catalyst Ageing Matters for Marine OEMs

CATAGEN recently supported a European marine OEM in validating a selective catalytic reduction (SCR) system for IMO Tier III compliance. Using the OMEGA reactor, we replicated 2,000+ hours of exhaust flow and poison exposure — without a single hour of engine runtime.

CATAGEN conduct all Catalyst Ageing and Characterisation at full scale on engine after-treatment systems using internationally patented technology; an Electrically Powered Synthetic Gas Recirculating Reactor: The CATAGEN OMEGA

CATAGEN helps OEMs ensure their aftertreatment systems meet these stringent global regulations without engine-based testing. Our process eliminates direct CO₂ emissions and dramatically reduces test energy requirements – helping you meet internal ESG targets as well as regulatory compliance.

Whether for auxiliary engines in offshore platforms or propulsion systems in large commercial vessels, CATAGEN helps marine OEMs validate aftertreatment system durability and compliance – without engine-based testing or fuel use.”

Meeting international emissions standards is not optional—it’s a strategic requirement. CATAGEN supports marine manufacturers in validating aftertreatment systems like SCR, ASC, DPF, TWC, and DOC for:

IMO MARPOL Annex VI compliance – limits NOx and SOx emissions
IMO Tier III – required in Emission Control Areas (ECAs)
IMO 2020 Sulfur Cap – 0.5% global sulfur content in fuels
EPA and CARB certifications for U.S. marine applications

The CATAGEN Toolset can track the ageing experience in real time using the proprietary CATAGEN Ageing Metric. This metric can be used to quantify the total ageing experience for comparisions, test design and degradation history for physical and virtual development of aged parts. We can match your desired catalyst bed temperatures, emissions and mass flows exactly. Where possible, eliminating fuel expenditure and CO2 emissions.
