Tiivistelmä
Today about 90 per cent of the world’s trade is concluded by using ships. This entails that the seafaring is one of the main attempters for the poisonous greenhouse gases.
Through the globalization and the tendency to produce and sell goods all around the world, leads to wider use of ship transportation and hence increasing emissions.
According to this fact it is important to find ways to abate ship emissions. This is supported with stricter emission limits in the Baltic Sea. To meet these regulations,
vessels need to have installed an emission abatement system. In the range of this thesis the two water-based NOx abatement measures DWI and HAM are observed, especially regarding their cost-effectiveness.
To find a figure how many € per abated ton of NOx these technologies cost, a case study with two ships was made. One ship was retrofitted with a HAM system and the other ship was new build with DWI technology. The calculations were based on
figures found in literature and the ship owners.
In conclusion, the costs per abated ton of NOx vary greatly with the specific ship. For DWI they are in the range from 243,25 €/t to 928,08 €/t. The HAM system is not so cost-intensive it varies from 282,58 €/t to 378,46 €/t.
