MAN ENERGY SOLUTIONS CASHES IN ON TIER III EXHAUST AFTER TREATMENT

Friday, February 12, 2021 

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

About 25%of the orders have been for EGR (Exhaust Gas Recirculation) systems, with SCR (Selective Catalytic Reduction) systems accounting for the remainder. The milestone was passed in early-January 2021 and is built upon references from the company’s portfolio of ME-B, ME-C and MC-C fuel-oil engines. Currently, almost half of all these orders have entered active service.

Bjarne Foldager, SVP Head of Two-Stroke Business, MAN Energy Solutions, said: “This is a notable milestone that is built on the know-how we have amassed over the past decade or so. 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 prioritise environmental considerations.”

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 by the combustion process.

Uniquely for the two-stroke sector, MAN Energy Solutions offers 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 in 2011, while SCR-HP won its first order in January 2019 and features a drastically reduced reactor size compared to rival systems.
