Volvo Penta secures Stage 5 certification for marine use

Volvo Penta has received Stage 5 certifications for marine use for its D8 and D13 packages.

The company also announced that the dry cargo vessel MBS Zuiderdiep has become the first vessel to be equipped with D13 Stage 5 marine engines – the first of their type to enter the European market.

In November 2020, Volvo Penta announced the introduction of 8 and 13 L engine packages that meet the requirements of the new EU Stage 5 marine for Inland Waterways legislation (IWW). The company offers a range of Stage 5 certified products – from 156 to 298 kW and up to 300 kW marine gensets.

The first D13 Stage 5 marine engines were recently delivered to Dutch company, Lemmen Diesel Engines B.V., who will be responsible for the repowering of the Zuiderdiep. This delivery marks the beginning of Volvo Penta’s Stage 5 offering with more deliveries already in the pipeline, the company said.

The company added that both the D8 and D13 engine ranges comply with the standards by leveraging Volvo Penta’s IMO Tier III technology, which uses a Selective Catalytic Reduction (SCR) after-treatment system.

After more than 65,000 hours of testing – at Volvo Penta facilities and commercial customer applications – the SCR solution has been adapted for marine conditions. The system is built to cope with high sulphur fuel 1,000 ppm and sustain high backpressure while maintaining engine efficiency and drivability. The SCR package also results in quieter operation, with noise levels reduced by 35 dBA, said Volvo Penta. The SCR unit is of a single-box design and the mixing of the Urea takes place inside the muffler.

“This is a big step in Volvo Penta’s sustainability commitments to meeting the most challenging emissions regulations,” said Jan-Willem Vissers, director of Marine Commercial Europe. “We’re helping our commercial customers move with the times, comfortably and efficiently.”

Lemmen is an independent workshop that specialises in repowering and revisions of engines. The company is a Volvo Penta specialist that works with Volvo Penta’s distributor Haisma Scheeps & Industriemotoren B.V., who in turn delivered these engines.

“Over the years we have successfully installed many Volvo Penta engines in all kinds of marine applications,” said Gijs Lemmen owner of the company. “The Volvo Penta engines have proven themselves as very reliable and hassle-free engines and that’s why we advise the use of Volvo Penta engines.”

The delivery consists of two D13 MH 298 kW at 1800 r/min Stage 5 certified engines.
