NOx clock running down

Environmental responsibility, particularly in respect of Nitrous Oxide (NOx), was the focus of attention for over a hundred members of the shipping industry who attended a UAE branch technical meeting of the Institute of Marine Engineering, Science and Technology, when Magdolin Mikhail, Upstream & Design Manager, Cummins presented ‘ ‘Evolution of emission regulations and new technologies to support the marine industry’.

Many attended conscious of the fact that deadlines on emission regulations loom; the International Maritime Organization (IMO) has designated the Baltic Sea and the North Sea as Emission Control Areas for NOx for ships with keel-laying on or after 1 January 2021.

During the meeting Magdolin Mikhail highlighted not only key dates, but the following facts about NOx:

IMO Tier III levels are currently in force in NOx Emission Control Areas (NECAs) within 200 nautical miles from the North American and US Caribbean shores. These requirements are applicable to all new build vessels (400 gt and above) or a retrofit project involving installing an engine with a power output of ≥130 kW and LOA ≥24 meters. NECAs will increase in future therefore there is no one effect date for IMO Tier III globally.

Emissions from ships in EU waters are to some extent limited by regional and global regulations as EU and its Member States have a strong preference for a global approach led by the International Maritime Organization (IMO).

It is through technical meetings like these that the IMarEST promotes its mission to work with the global marine community to promote the scientific development of marine engineering, science and technology.
