Results
First vessel have completed more than 1 year of successful operation. Currently 4 vessels have completed installation
By end 2011 all six patrol vessels will have BLUNOX SCR systems installed
NOx-reduction up to 95%
Airless design means a minimum of moving parts/electronics and a very compact system which is ideal for retrofit when space is limited
Airless operation means no need for compressed air and no extra fuel consumption

The vessels comply with IMO requirements valid from 2016 and on
