The turnkey project involved the fitting of combined Wärtsilä NOx Reducer (NOR) and Oxidation Catalysts (OXI) to the MSV Fennica and MSV Nordica.

Wärtsilä has carried out modification work for two of the company’s vessels belonging to Finland-based Arctia Offshore Oy. Both multi-functional vessels are based on a modified icebreaker design. The ships have be converted to enable the use of Ultra Low Sulphur Diesel fuel. The work involved fitting the combined Wärtsilä NOR/OXI solution to each of the eight engines that drive the two vessels.

The emission control device consists of a combined abatement system designed to reduce nitrogen oxides (NOx) and to enable the oxidation of carbon monoxide and unburned hydrocarbons. The NOR is a customized solution specifically engineered to meet the EPA’s emission standards. Retrofitting two of its icebreakers with state-of-the art catalytic converters opens up a whole new market for the Finnish company Arctia Shipping.
