Osaka-based Hitachi Zosen Corporation (HZC) has received an order from China's Dalian Marine Diesel Co for two units of its high-pressure selective catalytic reduction (SCR) system, set to be installed on a 7,999 DWT chemical tanker for Tier III NOx compliance.
Hitachi Zosen says this is the first order received by a leading Japanese manufacturer of large diesel engines for exhaust gas treatment equipment compliant with Tier III NOx emission standards.
The SCR systems will be installed in two 7,999 dwt chemical tankers being built for a European shipping owner by China's AVIC Dingheng Shipbuilding Co.
The order comes as a result of the high reliability of the system and makes Hitachi Zosen the global frontrunner in supplying systems designed to support maritime transport in compliance with environmental regulations.
“Hitachi Zosen is the only commercial distributor officially approved by the world’s leading licensor of large low-speed marine diesel engines, MAN Diesel & Turbo SE (Germany). We aim to make our marine SCR system the de facto standard of equipment compliant with Tier III environmental regulations,” says Jitsuhiro Yamaguchi, director of the Marine Machinery & SCR Systems Business Unit.
The world’s first marine SCR system developed by Hitachi Zosen uses a catalyst to render harmless NOx contained in the exhaust of diesel engines during operation.
Hitachi Zosen is globally the only manufacturer of both large marine diesel engines and catalysts and through in-house production realizes an ideal balance between compactness of the system itself and of catalyst volume, and the performance of catalytic activation.
