IMO: The International Maritime Organization (IMO) regulates exhaust emissions on Diesel engines above 130 kW (174 hp). Engines used exclusively in emergency applications are exempt. IMO Tier III applies only when operating within NOx Emission Control Area. To minimize global NOx emissions, IMO Regulation 13 sets NOx emission limitations on installed marine diesel engines (>130kW) and varied by RPM. The NOx limitations for diesel engines are regulated under 3-tier system, i.e. under Tier I, II and III Where’s NOx Tier status Applied? IMO Tier II and Tier III Standards Tier II and Tier III control set respective NOx limits for ship operation using low-sulphur fuels (0.5%), both outside and inside NOx Emission Control Areas (ECAs). For operation inside ECAs, a ship engine must be able to switch operations to meet Tier III standards.

The existing Baltic and North Sea SOx ECAs have been designated as NOx ECAs under IMO Resolution MEPC. 286(71), with the IMO NOx Tier III requirements to be applicable from 1 January 2021. IMO ANNEX VI NOx LIMITS Tier III - 1 Jan 2015 n<130rpm = 3.4g/kWh 130rpm2000rpm = 2.0g/kWh Tier II - 1 Jan 2011 n<130rpm = 14.4g Tier III emission control area are temporarily exempted provided the following conditions are met: .1 the engine meets the Tier II NO X limits; and .

IMO Tier II and Tier III Standards Tier II and Tier III control set respective NOx limits for ship operation using low-sulphur fuels (0.5%), both outside and inside NOx Emission Control Areas (ECAs).

If other ECAs for NOx are implemented, the NOx Tier III requirements will not be retroactive.

Certification issued in accordance with the 1997 NOx Technical Code would still remain valid over the service life of such engines. IMO Tier III applies to engines > 130 kW for controlling NOx emissions.

NOx Tier III rule to be implemented by 2021. The International Maritime Organisation (IMO), at its Marine Environment Protection Committee meeting held from 13-17 May rejected a proposal submitted by Turkey and ICOMIA that sought to mitigate the impact caused by the Tier III regulation. NOx is a pollutant released by combustion engines.

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. Examples of NOx Tier III compliance ‘NACC Alicudi’ ‘NACC Aluidi’ is the first cement carrier that complies with IMO Tier III compliance. The ship was converted in 2017 and is now a 120m self-discharging cement carrier.
