Damen Shipyards says it has achieved official EU Stage V certification for its in-house developed emissions reduction system.
The Damen Emission Reduction System (ERS) is a one-system-solution that 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.
With the certification, Damen says it can now offer its clients a proven emission reduction system that meets the requirements of the IMO Tier III, ULEV and EU stage V regulations.
The ERS is designed for both primary and auxiliary engines generating between 300 and 700 kW of output, and sea-going vessels equipped with the system are eligible for obtaining the Ultra-Low Emission Vessel classification notation.
The development of the EU Stage V system began in 2017 after Damen achieved 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,’ said Raymond Watson, Technology Specialist Aftertreatment Systems at Damen. ‘For example, they are designed to work with all standard fuels to ensure worldwide operability, and their modular design means that they can be installed on all types of vessel, matched to the specific operating profile of each.’
Damen is currently working on the certification of the ERS for multiple propulsion trains with outputs up to more than 4000 kW, all of which will soon be available as IMO Tier III, ULEV and EU stage V certified systems for both new build and retrofit vessels.
