HHI Slashes NOx Emissions from Marine Engines

HHI South Korea-based shipbuilder and marine engine maker Hyundai Heavy Industries (HHI) has produced the world’s first High Pressure Selective Catalytic Reduction (HP SCR) system for the dramatic reduction of NOx emission from 2-stroke marine engines. According to HHI, the HP SCR can reduce NOx emission up to 99 percent by using ammonia as a catalyst, and thus complies with IMO NOx Tier III requirement that took effect in January 2016. HHI completed the certificate test of the HP SCR, the fruit of an 18-month long research and development, in December 2015 with the presence of DNV-GL. The first HP SCR is slated to be installed in a 20,600 m3 LPG carrier under construction at Hyundai Mipo Dockyard, a shipbuilding affiliate of HHI on February 5, 2016, the company added. HHI won the orders of five HP SCR to date, and set the annual order target of more than 100 units by 2018.
