World’s most eco-friendly cruise ship starts service in Finland

M/S Viking Grace dramatically cuts sulphur oxide, nitrogen oxide and particulate matter emissions by using Liquefied Natural Gas as fuel.

M/S Viking Grace, the most environmentally friendly large cruise vessel ever built, has started operating between the city of Turku in Finland and the Swedish capital Stockholm. The Viking Line ABP’s 2,800-passenger ferry was built by STX Finland and is powered by Wärtsilä engines from Finland which use Liquefied Natural Gas (LNG) as fuel, dramatically reducing the ferry’s emissions and improving energy-efficiency.

The use of LNG as fuel will eliminate almost all sulphur oxide emissions and reduce nitrogen oxide emissions to at least 80% below the International Maritime Organization’s current stipulated level. This means that the ship can sail without restrictions in Sulphur Emission Control Areas and Nitrogen Emission Control Areas. Particulate matter emissions will also be cut by more than 90% compared to emissions from conventional diesel engines, with carbon dioxide emissions reduced by 20-30 percent.

Complete energy monitoring

One notable environment-friendly system on the Viking Grace is a complete energy monitoring tool called EMMA Advisory Suite supplied by ABB Oy Marine. EMMA contains all the tools required for onboard monitoring as well as options for optimization and fleet level follow-up.

Wärtsilä is also supplying a sound absorbing system to minimise the noise generated by the engine, increasing passenger comfort. In addition to being the most environmentally friendly cruise vesssel, M/S Viking Grace has a huge array of distinctive design details on board. Construction work on the M/S Viking Grace started at the STX Turku shipyard in September 2011, and the ship was floated out in August 2012.
