MAN Diesel & Turbo SE (MDT) has been awarded an approval in principle for its selective catalytic reduction (SCR) system for its entire medium-speed engine portfolio, which fulfils IMO Tier III regulations, by the China Classification Society (CCS).
Testing took place on an MAN 8L21/31 auxiliary engine with an integrated SCR system, but the certificate applies to the entire medium-speed engine portfolio, a statement of MAN said.
The MAN-built engine is bound for a DFDS Seaways Ro-Ro vessel, 2004-built Denmark (Dis)-flagged Petunia Seaways.
Goetz Kassing, chairman and head of MDT China, received the certificate on behalf of MDT from Sun Feng, vice-president of CCS, on 15 April in Shanghai.
“This certificate represents an important milestone in our collaboration with CCS and is of upmost importance in providing a complete IMO Tier III package solution to our customers,” said Dr Daniel Struckmeier, MDT senior project manager.
“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 MDT engine portfolio from 5L16/24 to 18V48/60. 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 MDT SCR modelling tool,” Dr Struckmeier added.
In December 2013, MDT signed a framework agreement with CCS for technical co-operation at Marintec China 2013. Both parties have since strengthened their co-operation in the fields of ship technology, ship-type research and development, and market co-operation.
