Nitrogen Oxide (NOx) is one of the gaseous pollutants from ships regulated by the International Convention for the Prevention of Pollution from Ships (MARPOL Annex VI(1)), published by the International Maritime Organization (IMO) . 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).

If other ECAs for NOx are implemented, the NOx Tier … IMO MEPC 70 has agreed to limit NOx emissions from ships' exhaust gases in the Baltic Sea and the North Sea. After final confirmations at the next MEPC meeting in spring 2017, these two decisions will create a larger NECA for new ships built in or after 2021. 2014-04-06 The control of diesel engine NOx emissions is achieved through the survey and certification requirements leading to the issue of an Engine International Air Pollution Prevention (EIAPP) Certificate and the subsequent demonstration of in service compliance in accordance with the requirements of the mandatory, regulations 13.8 and 5.3.2 respectively, NOx Technical Code 2008 (resolution MEPC.177 Define IMO NOx tier. means the NOx standards as set forth in the IMO MARPOL Annex VI and as certified by requirements set forth in IMO Regulation 13.
