HHI invents new high pressure SCR system to reduce ship emissions





Hyundai Heavy Industries, the world’s largest shipbuilder, announced that it 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.

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. The eco-friendly marine engine add-on has drawn keen attention from major shipping companies because it can run on heavy fuel oil that costs half as much as marine gas oil.

HHI completed the certificate test of the HP SCR,
the result of an 18-month-long research and

development process, in December 2015 with the presence of DNV-GL. The first HP SCR was 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.

HHI has won orders for five HP SCR to date, and
set the annual order target to more than 100 units
by 2018.

In response to recent harsh challenges in the shipbuilding industry, Hyundai Heavy industries is increasing efforts to develop new technologies targeted at the market demands for "eco-friendly, more efficient and smarter ships."
