Compliance with Tier III Standard is not safe, not efficient at economy mode, results in higher CO2 emissions – expert opinion
Compliance with the Tier-III Standard aimed at reduction of Nitrogen Oxide (NOx) emissions from ships by 80% involves a number of technological and ecological risks, IAA PortNews journalist cites Aleksandr Punda, professor at Admiral Makarov State University of Maritime and Inland Shipping, as saying at the Conference on Baltic and North Sea NECA Roadmap.
The expert says that application of SCR technology for reduction of NOx emissions in high seas can cause the failure of shipboard systems. Besides, this technology is not efficient at low engine speed when ships operate at economy mode or maneuver in ports. Moreover, compliance with the mentioned standard results in higher CO2 emissions, which is not consistent with the requirement on improving of ships’ EEOI.
As Joseph McCarney, representative of the International Association for Catalytic Control of Ship Emissions to Air, said at the Conference, there were cases of calcium sulfate fallout on ship’s deck. There is also a problem of disposing spent catalysts containing hazardous substances.
From January 1, 2016, sulphur content in fuel should not exceed 0.10 % in emission control areas (SECAs).
