A series of advanced selective catalytic reduction (SCR) systems has been installed on Van Oord’s cable-laying vessel (CLV) Nexus by Damen Shipyards Group in an effort to further reduce emissions.Five SCR units have been installed on the Nexus, one for each engine.SCR is an advanced emissions control technology. It contains a catalytic converter behind the engine which reduces nitrogen (NOx) emissions to an absolute minimum.It works by a catalyst which reacts with injected urea, chemically removing NOx from the vessel’s exhaust emissions.
