BIG ships, BAD atmosphere? Emissions
When talking about ship emissions one generally looks at particulates (PM), sulphur oxides (SOx), nitrogen oxides (NOx) and carbon dioxide (CO2) volumes in the air. Heavy oil is still common in the shipping industry and causes high SOx-emissions due to its high content of sulphur. This is why sulphur limit values for vessel fuels have been stipulated. While there is a sulphur limit value of 3.5 percent for shipping applicable for all oceans, IMO has introduced stricter regulations for certain marine areas, so-called Emission Control Areas (ECA). In these areas, vessels have only been allowed to use fuels with a sulphur maximum of 0.1 percent since 2015. The North Sea and the Baltic Sea are Sulphur Emission Control Areas (SECA) and as of 2021 they will be the only also NOx Emission Control Areas (NECA), alongside the North American coast. If a ship is allowed to emit 14.4 g NOx/kWh today, new ships will then
only be allowed 3.4 g NOx/kWh, id est a reduction of 75 percent. To note here is that in Kiel “Europa 2” as well as “Mein Schiff 3” to “Mein Schiff 6” already utilize catalysts for nitrogen oxide cleaning. In order to further reduce emissions stemming from ship operations, shipping companies also count more and more on alternative fuels for their new vessels.

Is this possible in the port of Kiel?
The result of calculations and orienting air pollution measurements at Kiel’s terminal facilities by the responsible State Agency for Agriculture, Environment and Rural Areas Schleswig-Holstein (LLUR) is that all short-term and long-term values of sulphur dioxide and nitrogen dioxide are significantly below the threshold values and the immission values for protecting human health. The LLUR measurements were performed from the beginning of April until the end of September 2008 at a distance of 200 metre beeline from the cruise terminal Ostseekai. In 2008, 126 cruise ships called at Kiel. Back then, ships were still allowed to use fuels with a sulphur content of 1.0 percent. And today? PORT OF KIEL commissioned an LLUR-approved engineering company for air quality control and immission protection in order to conduct long-term measurements in the port of Kiel regarding sulphur-oxide, nitrogen-oxide and particulate matter.
