1. Hyundai Heavy Unveils SCR Gas Emission
Reduction System
Hyundai Heavy Industries, the world’s biggest shipbuilder and a leading marine engine
manufacturer, announced today that it will supply 18 gas
emission reduction systems for three drillships ordered by
Rowan in June 2011.
The eco-friendly selective catalytic
reduction (SCR)system can reduce NOx emissions by as
much as 95% by using an HHI-developed catalyst to
separate NOx into nitrogen and water.
Analysts forecast the demand for the gas emission
reduction system will surge in 2016 when International
Maritime Organization Tier III emission limit regulations
come into effect. Under those maritime regulations, ships
built from 2016 should reduce NOx 80% less than Tier I
level to 1.96 grams and 3.4 grams per kilowatt hour.
Along with the SCR type, Hyundai Heavy is also developing
Exhaust Gas Recirculation (EGR) type gas emission
reduction system.
The Ulsan, South Korea-based company also completed test run of green gas marine engines
emitting 20% less carbon dioxide than diesel engines and reducing NOx emissions by 97% to reach
world’s lowest level of 50 ppm, and improves engine performance by 47% in June this year.
