MAN Energy Solutions’ Two-Stroke Business has booked more than 1,000 orders for secondary-measure, IMO Tier III-compliant, emission-reduction technology for its portfolio of MAN B&W-branded, low-speed engines.

Approximately one-quarter of the orders have been for EGR (Exhaust Gas Recirculation) systems, with the rest being for SCR (Selective Catalytic Reduction) systems accounting for the remainder.

The 1,000-order milestone was passed in early-January 2021 and is built on solutions for the company’s portfolio of ME-B, ME-C and MCC fuel-oil engines.

Currently, almost half of all the systems ordered have entered active service.

“This is a notable milestone that is built on the know-how we have amassed over the past decade or so,” said Bjarne Foldager, Senior Vice President and Head of Two-Stroke Business at MAN Energy Solutions “Our fully-mature EGR and SCR systems not only achieve Tier III NOx-compliance, but also deliver performance upgrades for engines in terms of increased fuel efficiency and lower, general emissions. As such, our ability to treat a ship as a complete system gives us a clear market advantage that enables us to prioritize environmental considerations.”

NOx SOLUTIONS

Exhaust gas recirculation (EGR) prevents the formation of NOx by controlling the combustion process, while Selective Catalytic Reduction (SCR) uses a catalyst and an additive to reduce the NOx generated in the combustion process.

MAN Energy Solutions is unique in the two-stroke sector in offering both EGR and SCR as proprietary NOx solutions, including both low- and high-pressure variants of the latter.

The company has long experience with EGR technology and reported its first order back in 2011, while its first order for SCR-HP, which features a drastically reduced reactor size compared to rival systems, came in January 2019.
