Taking Power Onboard

Wärtsilä providing propulsion package for passenger ferries

Posted on September 11, 2013

Wärtsilä will supply an integrated package for two dual-fuel liquefied natural gas (LNG) Ro-Pax passenger ferries being built on behalf of Canadian ferry services provider Société des traversiers du Québec (STQ). The contract was issued in August by Chantier Davie Canada (Davie), the builder of the two vessels.

 For each vessel, the contract includes the supply of Wärtsilä 20DF engines, the Wärtsilä LNGPac fuel storage and treatment system, Wärtsilä electrical power and automation systems, and Wärtsilä's Control & Communication Centre (3C), the integrated bridge control, navigation, and communication control system. Wärtsilä will also provide the yard with site management and commissioning services.

The Ro-Pax ferries will operate on LNG fuel, but the company’s dual-fuel engine technology allows the engine to switch to other fuels if needed.

 The two Ro-Pax double-ended passenger ferries are each capable of accommodating 432 passengers and eight crew members, and offer various capacity combinations for up to 115-car equivalent units or 16 tractor semi-trailers. They will operate throughout the year between Tadoussac and Baie-Sainte-Catherine on the Saguenay River in Québec, Canada, and are scheduled to start service in 2015.
