Marine propulsion and power generation
From massive cargo ships to smaller harbor craft such as ferries, barges, and tugboats, marine vessels contribute to air pollution in many cities and harbor areas, impacting air quality around the world. The Diesel Particulate Matter (DPM) emitted from the engines on these ships and from power generation negatively affects the health of local populations and contributes to global warming. 21% of black carbon emissions come from marine vessels, drifting hundreds of kilometers from the original source.
Regulatory agencies, including the California Air Resources Board (CARB), US Environmental Protection Agency (EPA), and International Maritime Organization (IMO), have programs in place to reduce emissions from diesel vessels.

Reducing the impact of diesel engines on seaside communities
At Rypos, we design and manufacture Diesel Particulate Filters (DPFs) that immediately remove up to 95% of DPM from emissions from marine diesel gensets and propulsion engines immediately on installation. Our proven, reliable, and durable emission solutions offer higher uptime and lower maintenance costs for operators and a safe, cleaner environment for passengers.

Application-specific
Featured project: US Navy barge retrofit
When the US Navy wanted to explore sustainable options for their fleet, our team proposed an extended field trial to determine the compatibility of Rypos technology with the harsh marine environment. We installed one of our active DPFs on a Marine barge tender, where it performed flawlessly for more than 5 years. When we removed it for evaluation, we were pleased to find that our Rypos DPF significantly exceeded the project’s emission reduction targets.
