Abstract

With global vessel fleet numbers anticipated to rise, the trend in maritime operations is projected to rise as well. This poses problems, as shipping emissions can pose human-health related and environmental dangers but maritime operations are not currently subject to the stringent requirements applied to land transport, including adherence to existing laws and policies, with amendments for emission-associated regulations. As shipping-inventory related approaches associated with emissions can be unpredictable, this study seeks to determine ways to estimate the emissions produced by ships with accuracy, through use of an appropriate methodology and its practical application to measure emissions aboard a 27198 GRT heavy hauler.

This will be done by analysing the measured emission discharges from the main engine (ME) of a slow speed diesel (SSD) with a 6880 kW capacity as the ship moved across the berth. The medium speed diesel (MSD) fitted with an auxiliary engine (AE) for the second set of measurements. Emission discharges were about 465 kW. To produce verifiable and unbiased results, a general prediction methodology is applied to analyse emissions primary gases and particulate matter. The results obtained are then compared with different standards and methodologies. Of the three operation modes considered i.e. at berth, manoeuvring and cruising, the results of the USEPA methodology are the closest, suggesting the precision of the methodology. The results should help upgrading the relevant policies regarding the application of the emission inventories.
