M/S Viking Grace, said to be the first large passenger vessel (gross tonnage 57,000) in the world fuelled by liquefied natural gas (LNG), was launched at STX Finland’s shipyard in Turku earlier this month. By using this fuel alternative, Viking Line will reduce emissions: nitrogen by 85%, CO2 by 20%; sulphur and particulate emissions are practically zero.
The LNG tanks are located outside on the rear deck. All gas pipes are double-mantled, which means that no gas is emitted into the engine room in case of any leakage. The vessel, capable of 22 knots, will refuel from an LNG supply ship under arrangement with AGA Gas AB, a member of the Linde Group.
The natural gas powered ferry, ordered by Viking at the end of 2010, will begin scheduled service on January 15, 2013. A maiden voyage, which will also be sold to the public, is planned for January 13. Tickets for this unique all-inclusive cruise will go on sale in the autumn.
