has contributed to the development of more stringent international NOX legislations within the framework of the International Maritime Organization (IMO).

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.

Set 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. 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. The regulations apply to vessels in North America, the US Caribbean, the Baltic Sea, the North Sea, and all future NOx Emission NOx emission limits are set for diesel engines depending on the engine maximum operating speed (n, rpm), as shown in Table 1 and presented graphically in Figure 1. Tier I and Tier II limits are global, while the Tier III standards apply only in NOx Emission Control Areas. 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.

Simon Hodgkinson Two additional NOx ECAs came into effect on the 1 st of January this year, covering the North Sea and the Baltic Sea and enforcing the Tier III standard against ships built after 1 January 2016. IMO Tier III applies to engines > 130 kW for controlling NOx emissions. The level of NOx emissions for Stage V and IMO engine > 130 kW are approximately similar. 2.2 Technical Specification - Stage V engines are certified in accordance with the NRMM Regulation.

Diesel engines for installation on ships constructed on or after 1st January 2016 are subject to IMO Tier III requirements when a ship is operating in a NOx Tier III Emission Control Area (NOx ECA) as designated under Regulation 13 of MARPOL Annex VI. For Damen, the IMO Tier III NOX regulations represent a significant move towards cleaner and greener operations. Improving air quality in harbours is an important issue, especially when taking their proximity to urban locations into account. Damen has a large number of tug-owning clients in the North Sea and Baltic Sea Emission Control Areas. Therefore the significance of IMO Tier III cannot IMO TIER III BACKGROUND MARPOL 73/78 – “ International onvention on the Prevention of Pollution from Ships” – Contains IMO Ship Pollution Rules 27th September 1997 – Inclusion of Annex VI to the MARPOL Convention by “1997 Protocol” Annex VI – “Regulations for the Prevention of Air Pollution from Ships” Sets limits for NOx and SOx emissions from Ship Exhausts (Regulations 13,14) with the IMO NOx Tier III requirements to be applicable from 1 January 2021.

IMO steg III inebär max 2.0 g NOx/kWh @ 1800 rpm. I dagsläget finns ingen dieselmotor som uppfyller kravet utan installation av någon form av efterbehandlingsmetod, till exempel katalysator (SCR eller EGR). IMO Tier III focuses on NOx limits, seeing as how NOx damages eco systems as well as posing health hazards in general. The Volvo Penta SCR solution reduces NOx levels by up to 75%.

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. 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.

Emission limits are commonly referred to as Tier I, II and III. Tier III refers to the NOx emissions. 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.
