IMO Marine Engine Regulations. Background; NOx Emission Standards; Sulfur Content of Fuel; Greenhouse Gas Emissions; Other Provisions; Background. International Maritime Organization (IMO) is an agency of the United Nations which has been formed to promote maritime safety. It was formally established by an international conference in Geneva in 1948, and became active in 1958 when the IMO


IMO tier III regulations (on NOX for marine vessels) to include Selective Catalytic Reduction technology September 6, 2013 Tagged with: Marine NOX Reduction , Selective Catalytic Reduction Marine vessel engines produce Nitrogen Oxides (NOx) during the combustion of fossil fuel which adds more than 14% to the global NOx production.

(66)). This is relevant given that the IMO TIER III (NOx) solutions (SCR) are relatively bulky due to the NOx reduction mechanism and the need to keep backpressure (maximum resistance) of the engine’s exhaust to a certain maximum. 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.

IMO3 regulations apply in designated sea areas referred to as NOx Emission Control Areas (N-ECAs). The NOx emission limits of Regulation 13 of MARPOL Annex VI apply to each marine diesel engine with a power output of more than 130 kW installed on a ship. A marine diesel engine is defined as any reciprocating internal combustion engine operating on liquid or dual fuel.

The Tier 3 NOx emissions regulations (IMO3) of the International Maritime Organization (IMO) that came into force on January 1, 2016 stipulate an 80% reduction in emissions relative to Tier 1 (but do not apply retroactively). IMO3 regulations apply in designated sea areas referred to as NOx Emission Control Areas (N-ECAs). Image Credits: NOx Tier III emission standards are applicable only in NECA (NOx Emission control areas). Outside NECA, Tier II standards are applicable. Current NECA areas are the North American area and the U.S. Caribbean area. 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. These limits range from 17 to 9.8 g/kWh depending on the engine speed, with higher limits for slower engines.

In October 2013, due to the lack of firm IMO decision on implementation dates the Baltic Sea countries were in a difficult negotiation positions during the HELCOM Ministerial Meeting. The Countries did not agree on new substantial decisions regarding the Baltic Sea NOx ECA submission to IMO MEPC, despite lengthy negotiations.
