| Zusammenfassung |
| A method is presented for the evaluation of the exhaust emissions of marine
traffic, based on the messages provided by the Automatic Identification
System (AIS), which enable the positioning of ship emissions with a high
spatial resolution (typically a few tens of metres). The model also takes
into account the detailed technical data of each individual vessel. The
previously developed model was applicable for evaluating the emissions of
NOx, SOx and CO2. This paper addresses a substantial
extension of the modelling system, to allow also for the mass-based
emissions of particulate matter (PM) and carbon monoxide (CO). The presented
Ship Traffic Emissions Assessment Model (STEAM2) allows for the influences
of accurate travel routes and ship speed, engine load, fuel sulphur content,
multiengine setups, abatement methods and waves. We address in particular
the modeling of the influence on the emissions of both engine load and the
sulphur content of the fuel. The presented methodology can be used to
evaluate the total PM emissions, and those of organic carbon, elemental
carbon, ash and hydrated sulphate. We have evaluated the performance of the
extended model against available experimental data on engine power, fuel
consumption and the composition-resolved emissions of PM. We have also
compared the annually averaged emission values with those of the
corresponding EMEP inventory, As example results, the geographical
distributions of the emissions of PM and CO are presented for the marine
regions of the Baltic Sea surrounding the Danish Straits. |
