Abstract

In the paper is described, and applied in some case studies, a complete methodology for the estimate of air pollutant emissions from ships in port environment and in navigation. The following pollutants are take into account: Nitrogen oxides, Sulfur oxides, and Carbon monoxide, Volatile Organic Compounds, Paniculate matter, Carbon dioxide. The paper introduces a schematic representation of ship traffic, from the point of view of consumption and emissions, subdividing the operation in: cruising, maneuvering, hotelling and tanker offloading. The emissions are estimated from daily fuel consumption, days spent in the different operations and average pollutants emission factors. The paper report regression formulas on fuel consumption at full power vs. gross tonnage (measured in line with the 1969 International tonn
