The emissions reduction possibility of sulphur compounds of vessels sailing in Emission Control Areas (ECA)

The article presents legal regulations, together with the characteristics of Emission Control Areas (ECA). It is connected with the new limit sulfur emissions in those areas. In this article the advantages and disadvantages of various solutions, i.e. switching to low sulphur distillates, installing the marine scrubber device and using of liquefied natural gas (LNG) as ship’s main fuel have been considered. Each of these solutions was described in respect of technological review, by the possibility of reducing harmful compound from exhaust gases, to investment costs. In another part of this thesis, there are the calculations of costs of fuel and necessary modifications for a selected passenger-car ferry. Costs were assessed for all of the mentioned solutions. The article was completed conclusions indicating which way is the most cost-effective.
