MAN gets first SCR IMO Tier III approval

MAN gets first SCR IMO Tier III approval
China Classification Society has granted the world's first IMO Tier III approval in principle to MAN’s Selective Catalytic Reduction (SCR) system for all its entire medium-speed engines.

Testing of the SCR system, designed to cut Nitrogen Oxide (NOx) emissions, took place on an MAN 8L21/31 auxiliary engine with an integrated SCR system set for delivery to DFDS ro-ro Petunia Seaways. The CCS award certificate applies to MAN’s entire medium-speed engine portfolio.

The move follows a framework agreement between MAN and CCS signed at 2013’s Marintec China, for cooperation in the fields of ship technology, ship-type research & development and market cooperation.

“We are glad to present the first Tier III Certificate to MAN. Based on the good cooperation, we can provide a better service for the marine and shipbuilding industry,” said CCS vp Sun Feng, at the Shanghai ceremony.

“China is MAN Diesel & Turbo’s most important market,” said Goetz Kassing, chairman and head of MAN Diesel & Turbo China. “As China has taken the next steps to higher levels of efficient and clean energy production for a sustainable and better environment, it is our priority to align our engines with the new policies to stay ahead of the competition.”

Senior project manager at MAN Diesel & Turbo Daniel Struckmeier said: “This certificate represents an important milestone in our collaboration with CCS and is of utmost importance in providing a complete IMO Tier III package solution to our customers.

“This milestone is one of three agreed major steps in a long-term relationship with CCS. The first step has been accomplished after issuance of the first IMO Tier III EIAPP certificate for the 21/31 engine group in February this year. Today’s award finalised the second step, which includes the certification of the MAN Diesel & Turbo-SCR modelling tool, covering the MAN Diesel & Turbo engine portfolio from 5L16/24 to 18V48/60.

“From today on, every customer can profit from the easy and effective way of IMO TIER III certification for all MDT four-stroke engines. The final step, planned for autumn of this year, will incorporate the issuance of a general approval of our entire engine portfolio based on the afore-mentioned MAN Diesel & Turbo SCR modelling tool."
