Wärtsilä Propelling Viking Line Forward

Posted on March 3, 2011

Wärtsilä has received a contract from shipbuilding company STX Finland Oy to supply the propulsion machinery for a new passenger ferry to be built for Viking Line, a Finnish ship owner. The ship, which will operate on liquefied natural gas (LNG), will be built at the STX Turku shipyard, in Finland, and is scheduled to enter service in 2013.

The vessel will sail between Turku and Stockholm, Sweden, in the Baltic Sea. The agreement includes an option for the supply of equipment to a similar sister ship. STX Finland is part of the international STX Europe Group. Wärtsilä's scope of supply for this contract includes four Wärtsilä 8L50DF main engines, the transverse bow and stern tunnel thrusters, and two stainless steel fixed pitch, built-up main propellers with propeller shaft lines and shaft line seal systems.

Because the vessel runs on LNG, nitrogen oxide emissions will be at least 80% below the International Maritime Organization's (IMO) current stipulated level, Wärtsilä said. There is also a reduction of particulate emissions of more than 90% compared with the emissions from conventional diesel engines, while carbon dioxide emissions are also 20 to 30% lower.

The Viking Line's cruise ferry will be capable of carrying cars, trucks and road trailers on short international voyages. It is also designed to carry 2800 passengers and 200 crew members. The machinery, equipment and outfitting, as well as the structural work, will be under the special survey of the Lloyds Register of Shipping classification society, Wärtsilä said.
