Wärtsilä has been contracted by the Korean yard STX Offshore & Shipbuilding, to supply exhaust gas cleaning systems for four new Container Ro/Ro (ConRo) vessels being built for Ignazio Messina & Co, the Italy based ship owner and operator. This latest order will enable the new vessels to comply with both current and pending environmental legislation relating to exhaust emissions. For ships sailing in European waters, the maximum sulphur content will be limited to 0.5% from 2020, while a tighter limit of 0.1% will apply from 2015 to ships operating in 'sulphur emission control areas' (SECAs), which include the North Sea, the Baltic Sea and the English Channel. The Wärtsilä systems supplied under the terms of this order will clean both sulphur oxides (SOx) and particulate matter emissions from the main engines, auxiliary engines, and the boiler. Deliveries are scheduled to take place during 2013 and 2014, and the vessels are to be delivered by the shipyard to Ignazio Messina & Co during the second half of 2014.
