| Zusammenfassung |
| In 1997 the International Maritime Organisation (IMO) adopted MARPOL Annex
VI to prevent air pollution by shipping emissions. It regulates, among other
issues, the sulfur content in shipping fuels, which is transformed into the
air pollutant sulfur dioxide (SO2) during combustion. Within
designated Sulfur Emission Control Areas (SECA), the sulfur content was
limited to 1 %, and on 1 January 2015, this limit was further
reduced to 0.1 %. Here we present the set-up and measurement results of a
permanent ship emission monitoring site near Hamburg harbour in the North
Sea SECA. Trace gas measurements are conducted with in situ instruments and
a data set from September 2014 to January 2015 is presented. By combining
measurements of carbon dioxide (CO2) and SO2 with ship position
data, it is possible to deduce the sulfur fuel content of individual ships
passing the measurement station, thus facilitating the monitoring of
compliance of ships with the IMO regulations. While compliance is almost 100 %
for the 2014 data, it decreases only very little in 2015 to 95.4 %
despite the much stricter limit. We analysed more than 1400 ship plumes in
total and for months with favourable conditions, up to 40 % of all ships
entering and leaving Hamburg harbour could be checked for their sulfur fuel
content. |
