Ship engine exhaust emission estimates for Port of Brisbane

An inventory of engine and boiler exhaust emissions from ocean going vessels (OGV), tugs and dredges for the Port of Brisbane is described. A detailed methodology is employed whereby the movements and consequent emissions of each individual vessel are estimated. It was estimated that about 47% of total OGV fuel consumption occurred at berth and about 43% during the relatively long transit of port waters. Nearly 60% and 56% respectively of the NOx and particles emitted by OGVs were during transit
