Finnish manufacturer Wärtsilä has won a contract from Italian shipbuilder Fincantieri to supply gas-powered propulsion machinery and equivalent gas storage and handling systems for a new passenger ferry.

Fincantieri is building the vessel, which is claimed to be the first North American ferry to be powered by liquefied natural gas (LNG), for Société des Traversiers du Québec (STQ) of Canada.

The equipment is scheduled to be delivered by Wärtsilä in autumn 2013.

Following the vessel’s scheduled delivery in 2014, it will be used for multiple services on the Matane-Baie-Comeau-Godbout route, undertaking around 1,600 trips to transport more than 200,000 passengers and 116,000 vehicles a year.

The Government of Quebec will provide finance for the 130m long vessel, which will be capable of transporting 800 passengers and 180 cars.

The ferry will be equipped with a two diesel electric propulsion system, azimuth thrusters with two counter-rotating propellers, and four diesel power generators capable of running on liquid natural gas (LNG) or marine diesel oil (MDO).

Main power generation for the vessel will be provided by the Wärtsilä 34 dual-fuel generating sets, which can reduce nitrogen oxide (NOx) emissions to 85% below current International Maritime Organisation (IMO) limits.

Compared to conventional diesel fuel engines, the Wärtsilä 34 dual-fuel generating sets reduce carbon dioxide (CO2) emissions by 25% and cut sulphur oxide (Sox) and particle emissions to close to zero.

Apart from the four main power generating sets, the vessel will also be equipped with Wärtsilä’s LNGPac system.

The LNGPac system includes onboard LNG bunkering, storage tanks and handling equipment, and related safety control and automation systems.

The ferry will be certified in the highest class designated by international registries for this type of service and will be in Ice class 1A and propulsion class 1 AS, the highest level awarded by the classification registries.
