Niigata diesel engine combined with Selective Catalytic Reduction (SCR) system is confirmed by ClassNK to meet IMO NOx Tier III Limit.
NIIGATA Power Systems Co., Ltd., (Niigata) recently performed NOx
measurement tests of the 28AHX medium-speed marine diesel engine
combined with the Selective Catalytic Reduction (SCR) system for showing
to comply with International Maritime Organization (IMO) NOX Tier III
Limit (more than 80% reduction of NOX emission from Tier I Limit).
Nippon Kaiji Kyokai (ClassNK) confirmed that it complied with IMO NOx
Tier III Limit and issued the Statement of Fact on 7th August, 2014.
Niigata has delivered the first SCR system for the marine propulsion
engine in 1995, nearly 20 years ago, which is still working. Based on
such a successful record, the certification of engines with SCR systems
in an expanded range will be continued. In order to meet the demand
towards implementation of the IMO Tier III Limit in 2016 in the Emission
Control Area (ECA), the production capability of SCR systems will be
organized.
Niigata has a complete line of SCR systems for marine diesel engines
ranging from 550 to 6,600 kW for both main propulsion and auxiliary
engines. Development of this SCR system utilizes the part of
technologies and findings for compact design in the research undertaken
by Niigata for “Super-clean Marine Diesel” Project of the Japan Ship
Machinery & Equipment Association (JSMEA) financially supported by
Nippon Foundation under initiative of the Ministry of Land,
Infrastructure, Transport and Tourism (MLIT).
