Damen Shipyards Group has recently carried out the installation of a series of selective catalytic reduction (SCR) systems to Van Oord’s Nexus, a Damen Offshore Carrier (DOC) 8500 delivered in 2014.
The Marine NOX Reduction system uses a catalyst to react with injected urea to chemically reduce NOX from the vessel’s exhaust gases. It is relatively compact, with all component parts combined.
“Damen’s system combines the damper and scrubber in one unit. With an existing vessel that has not been built with an SCR installation in mind, there is a minimum of space available, so a system such as this, which requires less volume, is ideal for a retrofit project.”
Developed in 2015 in preparation for IMO Tier III regulations. The system has proven itself on multiple applications on tugs, workboats, yachts and inland shipping vessels.
Reduced NOX emissions is increasingly becoming a license to operate, particularly in the offshore wind sector in which the Nexus is active.
The project required the installation of five SCR units, one for each of the Nexus’ engines. Extensive testing and verification has shown that, with the SCRs installed, Van Oord has reduced the NOX emissions of its vessel by up to 80%.
