Real sailing NOx emissions of sea-going ships with Tier III certified engines. Review of status quo and options for mitigation
report
TNO conducted a study for the Dutch Ministry of Infrastructure and Water Management about real sailing NOx emissions performance of seagoing vessels with Tier III certified engines. Particularly the emissions performance in the North Sea and in general the European ECA zones were the focus of the study, including technical and regulatory measures for improvement. The main objectives are: • Based on available studies and data, to determine the real sailing emissions of ships with IMO Tier III certified engines, and to determine whether shortfalls occur between observed emissions levels and applicable limits, possibly distinguishing between types, sizes and usages of ships. • To provide options to mitigate NOx emissions on the North Sea (including specific port and coastal areas) of ships with IMO Tier III certified engines. The study led to the overall conclusion that the NOx emissions of Tier III ships are higher than aimed for with the Tier III legislation.
