Damen has become the first shipyard to achieve official EU Stage V certification for its in-house developed emissions reduction system.
The Damen Emission Reduction System (ERS) combines soot filters with a selective catalytic reduction system to remove particulate matter and nitrogen oxides (NOx) as they leave the engine and before they enter the atmosphere. It also delivers noise reduction that averages 45 dB(A).
The Damen ERS is designed for both primary and auxiliary engines generating between 300 and 700 kW of output.
The development of the EU Stage V system began in 2017, afte rDamen achieving certification for its NOx reduction system to comply with IMO Tier III emissions regulations.
It has taken six years to reach this point, but our ERS goes beyond the parameters set by the regulators to ensure that they are robust and flexible
stated Raymond Watson, Technology Specialist Aftertreatment Systems at Damen.
Damen is currently working on the certification of the ERS for multiple propulsion trains with outputs up to more than 4000 kW, and all will be available soon as IMO Tier III, ULEV and EU stage V certified systems for both new build and retrofit vessels.
