If a vessel undergoes a major conversion or a new engine, substantially different from the old one, is installed the current standard would apply. NOx is a term used to describe nitrogen oxides.
NOx is a pollutant released by combustion engines. The International Maritime Organisation (IMO) has several NOx emissions regulations. Emission limits are commonly referred to as Tier I, II and III. Tier III refers to the NOx emissions.
The Clean Air Act; The Final Rule published on April 30, 2010: extends the ECA to the internal waters.

The control of diesel engine NO x 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
IMO NOx regulation. NOx pollution standards have been set on every type of motor vehicle and on stationary industrial units. 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
They will set NOx emission limitations to all vessels wishing to sail in the Nitrogen Emission Control Areas (NECAs) North America, US Caribbean, Baltic Sea and the North Sea. If you are planning a refit it is important to remember that the IMO Tier IIII certification will also apply when an engine is replaced by a new and more powerful one. Although the IMO delayed the adoption of the amendments for yachts under 500GT and over 24m LOA by five years (now coming into force in 2021), there’s no way to avoid the IMO Tier III NOx regulations.

In the third IMO greenhouse gas study, the Marine Environment Protection Committee (MEPC) argued that shipping contributes to 15% of the global nitrogen oxides (NOx) emissions. Unlike Sulphur oxides (SOx), NOx gases are not generated as a direct derivate of the fuel burned, but by the process of burning the fuel.
