Volvo Penta has responded to the new IMO III emission regulations for yachts over 24 m with a new VOLVO PENTA IMO III solution

By offering reduced emissions and improved fuel efficiency, Volvo Penta says the new solution, the D13 IPS1200-1350 and axle installations, builds on the company’s experience of IMO III commercial products and Volvo Group technology. extensively tested.

The solution has already proven its worth in harsh marine conditions, having undergone more than 65,000 hours of field testing at sea. Volvo says the system is built to handle high sulfur fuel (up to 1000 ppm) and cope with high back pressure while maintaining the engine’s efficiency and drivability.

System Advantages

Compact and flexible: The IMO Tier III solution is the most compact on the market, simplifying the transition to IMO III compliance. The design means that existing Volvo Penta IPS yachts will be able to adapt to the system without disruption in the engine room. Coupled with a patent pending modular and flexible outlet, the SCR system can be installed in both a vertical and horizontal position, making it an even more versatile solution.

Fully Integrated – Designed, developed and manufactured by Volvo Penta, providing optimized aftermarket support.

Service-free: Volvo’s SCR system does not require service and has the same service life as the engine to which it is attached.

Equal or better fuel efficiency – Engine manufacturer says it has met IMO III targets while reducing fuel consumption, despite exhaust back pressure, providing unchanged power output

Switchable between EPA III and IMO III compliance – The new VP system is designed to allow a switch between EPA III and IMO III compliance, ensuring flexibility when using the boat in regions with different emission laws.


Since January 2021, the IMO III Nitrogen Oxides (NOx) legislation that already applies to commercial vessels has been extended to maritime pleasure vessels above 24m load line length, which They sail in US waters, as well as the North and Baltic seas.

Providing another step towards greater sustainability in the industry, the 2021 legislation aims to reduce emissions. To comply, affected yachts must now be equipped with a Selective Catalytic Reduction (SCR) aftertreatment system, leading Volvo Penta to work on an optimized solution for its yacht customers for both IPS and traditional inner shaft installations. .
