Wärtsilä Powering New Passenger Ferry

Wärtsilä 34 dual-fuel generating sets part of package

Posted on December 4, 2012

Wärtsilä has received a contract to supply the gas-powered propulsion machinery and corresponding gas storage and handling systems for a new passenger ferry. Canadian operator Société des traversiers du Québec (STQ) order the ferry, which will be the first North American ferry to be powered by liquefied natural gas (LNG), the company said.

Fincantieri Cantieri Navali Italiani is building the ship, which will be used on routes crossing the St. Lawrence River. The equipment is should be delivered in the autumn 2013, with the vessel scheduled for delivery by the end of 2014.

The ferry is being built to comply with emission regulations applicable to its area of operation. With the Wärtsilä 34 dual-fuel generating sets, which will provide the main power generation, those regulations will be met, Wärtsilä said. By operating on LNG, nitrogen oxide (NOx) emissions are at least 85% below those specified in the current International Maritime Organization (IMO) regulations, and the CO2 emissions are about 25% less than those of a conventional marine engine running on diesel fuel. The sulfur oxide (SOx) and particle emissions are negligible at almost zero percent.

In addition to the four main power generating sets, Wärtsilä will also supply its LNGPac system. Designed and developed by Wärtsilä, the LNGPac comprises onboard LNG bunkering, storage tanks and handling equipment, as well as the related safety control and automation systems. All engines can be switched to marine diesel oil (MDO) operation if gas is not available.
