An IMO III Solution from Volvo Penta


At this week’s Cannes Yachting Festival, Volvo Penta revealed an IMO Tier III solution that fits a Selective Catalytic Reduction after-treatment system compatible with IPS engines as well its traditional shaft installations.

To accomplish this, Volvo Penta leveraged its parent company’s commercial technology that has already undergone more than 65,000 hours of at-sea field testing.

“We have gained a lot of experience during the years of designing after-treatment systems within the Volvo Group and for our industrial and marine commercial offerings,” said marine leisure product manager Björn Rönnvall in a statement. “This has enabled us to finetune the solution — extending its lifespan, maintaining and even bettering its fuel consumption, and delivering all this and more in a compact, flexible package. Ultimately, we want to make this transition as simple as possible for our marine yacht customers.”

Volvo Penta said its SCR system is the most compact currently available on the market and that it can be retrofitted to IPS-powered vessels without alterations to the engine room. With a flexible, modular outlet, it can be installed in a vertical or horizontal position.

The company added that its SCR system does not require service, will provide the same or better fuel efficiency for the vessel, and can be switched between EPA III and IMO III compliance, depending on the region.

Since January, the IMO III NOx legislation that already applies to commercial vessels has been extended to marine leisure vessels above 24m load line length that navigate in U.S. waters, as well as the North and Baltic Seas. Rules state that all vessels with a load line length greater than 78 feet will require the installation of an SCR system.

Volvo Penta’s SCR will be available for ordering in January 2022.
