CCS GUIDELINES FOR APPLICATION OF SELECTIVE CATALYTIC REDUCTION SYSTEM ONBOARD SHIPS
|D O W N L O A D|
The present official China Register Guidelines are intended to apply to the SCR, standing for the selective catalytic reduction systems that are installed to reduce the emission of NOx from the shipboard diesel engines. they stipulate all applicable class requirements for the design and onboard arrangement, control and monitoring, and post-installation testing of these systems.
Note that the content of the Guidelines does not include detailed requirements for the product inspection and type approval of the SCR systems. They are rather supplementing current CCS Rules and the systems shall comply with all relevant requirements of the rules. The Guidelines shall be applicable to the CSR systems with reductant using either aqueous ammonia or urea solution.
It shall be taken into account that special consideration and approval shall be there for the systems using liquid ammonia. The intent of the Guidebook is to provide necessary standards for these systems; compliance with subject standards will allow to minimize the potential harm to the vessel, crew members and environment. All functional requirements stated in the Guidelines shall be complied with in order to achieve this goal...
