The new vessel, will be equipped with six Wärtsilä 31DF dual-fuel engines, running primarily on liquefied natural gas (LNG), will provide propulsion and power for the vessel. The diesel version, of this same engine, has been recognised by Guinness World Records, as being the world’s most efficient 4-stroke diesel engine. This will be the first marine application for the dual-fuel LNG version. The combination of high efficiency, low fuel consumption and the reduced level of exhaust emissions from operating on clean-burning LNG, is expected to create low operating costs and leave a minimal environmental footprint.
Apart from the engines, Wärtsilä will supply its LNGPac fuel storage and supply system, an advanced Compact Silencer System, high quality bow thrusters, the ballast water management system (BWMS) as well as its Nacos Platinum integrated navigation system. The Nacos Platinum system integrates various functions into a single system, allowing the vessel to be navigated, controlled, and monitored from several onboard positions, thus providing unequalled flexibility and convenience. The BWMS, is designed to render the ballast water discharge harmless of invasive species. The installation of these systems will make the vessel compliant with both EU and International Maritime Organization environmental regulations that came into effect in September 2017. This vessel will start operations in 2021, crossing the Baltic Sea between Turku in Finland and Stockholm in Sweden. It is the first LNG fueled ferry of this size and standard to be built in China. This vessel is not the first car ferry to use LNG as a fuel. The first was the Viking Grace, equipped with Wärtsilä 31DF engines.
