Hyundai Heavy Industries (HHI) will supply 18 gas emission reduction systems for three drillships ordered by Rowan.
The eco-friendly selective catalytic reduction (SCR) system can reduce nitrogen oxide (NOx) emissions by as much as 95% by using a 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 IMO 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,” HHI said.
