It affects us all For the marine sector, at a global level, the Marine Environment Protection Committee (MEPC) of the International Maritime Organisation (IMO) agreed a three-tier structure for new engines in 2008, which would set progressively tighter NOx emission standards depending on their date of installation. Put forward by the UN’s International Maritime Organisation, Tier III of the IMO NOx regulations aims to reduce nitrogen oxide emissions (NOx) by approximately 70 per cent compared with the current Tier II standards. Any qualifying vessel built after 2016 that passes through a NOx ECA requires an approved and working control systems such as a Selective Catalytic Reduction (SCR) to trade. These SCR systems reduce the NOx content in the exhaust gasses of a ship’s engines by injecting a reducing agent into the exhaust system at a relatively low temperature.

NOx is a pollutant released by combustion engines. The International Maritime Organisation (IMO) has several NOx emissions regulations. Emission limits are commonly referred to as Tier I, II and III. Tier III refers to the NOx emissions. Figure 1.MARPOL Annex VI NOx emission limits. Tier II standards are expected to be met by combustion process optimization. The parameters examined by engine manufacturers include fuel injection timing, pressure, and rate (rate shaping), fuel nozzle flow area, exhaust valve timing, and cylinder compression volume.

The year 2016 will remain as entry into force date for the N IMO's NOx Tier III Regulations.
