The model is applied to the Australian region. The large geographical extent and 3 September 2014 number of included ports and vessels, and anomalies in the AIS data are challenging. Particular attention Accepted 10 September 2014 Available online 10 October 2014 is paid to filtering of the movement data to remove anomalies and assign correct operating modes. Data gaps are filled by interpolation and extrapolation. Emissions and fuel consumption are calculated for each individual vessel at frequent intervals and categorised by ship type, ship size, operating mode and Keywords: Ship engine exhaust emissions machinery ty
