Analysis and Measurement of NOx Emissions in Port Auxiliary Vessels

This paper examines nitrogen oxides (NOx) pollution emitted by port auxiliary vessels, specifically by harbour tugs, due to its unique operating characteristics of operation. These vessels require a large propulsion power changes discontinuously and also possess some peculiar technical characteristics, large tonnage and high propulsive power, that differentiate them from other auxiliary vessels of the port. Taking into account all the above features, there are no studies of the NOx emission engines caused by different working regimes of power because engine manufacturers have not measured these emissions across the range of operating power. Usually, only the pollution produced by its engines to a maximum continuous power is reported.
