Volvo Penta says it is continuing to meet increasing emissions standards with a new, expanded range of D8 IMO III solutions aimed at smaller, high-speed commercial vessels.

The latest launch expands marine commercial Volvo Penta D8 IMO III solutions for D8 IPS-600, D8 IPS-650, D8 IPS-700, D8 450 hp, D8 510 hp and D8 550. According to Volvo Penta, the enhanced offering enables a broader range of D8 propulsion packages to exceed IMO III emissions standards without compromising on power or efficiency. 

Market availability is expected in the first half of 2025. 

The new D8 IMO III solutions feature 6-cylinder, 7.7-litre diesel engines that can provide power up to 405kW and generate up to 550hp. They utilise common-rail fuel injection and twin-entry turbo with charge air cooling. 

“As emissions control areas expand, commercial vessels must comply with more stringent IMO III standards. Historically, there weren’t any IMO III solutions for smaller high-speed vessels, so they were exempt from restrictions. Now they must comply, so we have leveraged our IMO III technology for an expanded range of D8 solutions,” says Jan-Willem Vissers, director of marine commercial at Volvo Penta.

Essential to the expanded Volvo Penta D8 IMO III range is SCR (selective catalytic reduction) technology, which was developed across Volvo Penta and for the new D8 range, optimized for heavy-duty marine operations. 

With SCR, exhaust gases are combined with diesel exhaust and urea in the SCR unit, through the integrated urea injector pipe. Pre-installed in a urea daytank, urea quality and level sensors work together with a dosage pump to maintain the stringent IMO III emissions levels. 

The SCR unit can be installed in either a vertical or horizontal position, thanks to the new rotating outlet.

The Volvo Penta D8 IMO III range is compact and ideal for commercial workboats that travel at 20 to 40 knots, typically in the 15-metre size class. This includes pilotboats, CTVs, high-speed ferries, search and rescue boats, patrol and smaller work boats. 



When paired with Volvo Penta IPS and twin counter-rotating propellers, Volvo Penta says the D8 IMO III range offers excellent maneuverability, responsiveness, long action range, reduced fuel consumption, reduced noise and enhanced comfort. It becomes a fully integrated system that is designed, developed, and manufactured by one company. 

“The new Volvo Penta D8 IMO III range offers a complete solution for companies that aim to improve their fleets. They are easy to install and easy to maintain, and they will enable vessels to exceed current emissions standards without sacrificing speed, power or space,” Vissers says.
