A key example is the IMO NOx Tier III limits. These limits apply to engines installed on or after 1 January 2016, that are operating in Emission Control Areas (ECAs) and establish a strict limit on their emissions. What are NOx Tier III standards? NOx standards are divided into three categories:

NOx control requirements apply worldwide to any installed marine diesel engine over 130 kW of output power other than the engines used solely for emergency purposes not in respect of the marine vessel’s tonnage where the engine is installed. However, there are different levels of regulations that are based on the ship’s date of construction.

The levels of permitted emissions are defined in terms of the concentration of sulfur in the fuel being used, with different limits applying in designated sea areas known as SOx Emission Control Areas (S-ECAs) and elsewhere (GLOBAL). 6 percent reduction in marine diesel NOx emissions in the United States by 2020, and increasing to 7 percent by 2030. Again, while these estimates are only for the United States, they suggest the modest NOx reductions that can be expected world-wide from the current standards.

NOx control requirements apply worldwide to any installed marine diesel engine over 130 kW of output power other than the engines used solely for emergency purposes not in respect of the marine vessel’s tonnage where the engine is installed. However, there are different levels of regulations that are based on the ship’s date of construction.

IMO NOx Tier III requirements will take effect in North American and US Caribbean ECAs from January 1st 2016 for vessels with a keel-laying date on or after January 1st 2016 and an engine output of ≥130kW. If other ECAs for NOx are implemented, the NOx Tier III requirements will not be retroactive. 2013-05-16 Each Tier limits the NOx emission to a specific value based on the rated engine speed.

These limits range from 17 to 9.8 g/kWh depending on the engine speed, with higher limits for slower engines.

Nitrogen Oxides = Marpol (AnnexVI +NOxTechnical Code 2008) The NOx limits apply to engines installed on vessels that have power ratings over 130 kilowatts as described in table below. If a vessel undergoes a major conversion or a new engine, substantially different from the old one, is installed the current standard would apply. Those levels are broken down into 3 Tiers. Tier I applies to the ships built after January 1st of 2000. It states that for engines below 130 rpm must have the total weighted cycle emission limit (g/kWh) of 17, engines that are between 130 and 1999 rpm must have no more than 12.1 (g/kWh), engines above 2000 rpm must have the limit of 9.8 (g/kWh). The NOx control requirements of Annex VI apply to install marine diesel engine of over 130 kW output power other than those used solely for emergency purposes irrespective of the tonnage of the ship onto which such engines are installed. In the 2003 rule, EPA adopted Tier 1 NOx emission standards for Category 3 engines, which are equivalent to the international IMO MARPOL Annex VI limits.
