Tallink chooses Wärtsilä for dual-fuel ro-pax

Five Wärtsilä 50DF dual-fuel engines (three 12-cylinder and two six-cylinder) will power Tallink's new ro-pax ferry Five Wärtsilä 50DF dual-fuel engines (three 12-cylinder and two six-cylinder) will power Tallink's new ro-pax ferry

Tallink has selected Wärtsilä to power its dual-fuel ro-pax ferry on order from Meyer Turku.

The Finnish power company will supply the vessel with three 12-cylinder 50DF and two 6-cylinder 50DF main engines, as well as two fixed-pitch propellers and propeller shaft lines. The equipment will be delivered to the yard in early 2016.

The ferry order was reported late last year, and the vessel will run mainly on LNG when it is put into operation in early 2017. The 212m long ferry will have a gross tonnage of 49,000 and will carry 2,800 passengers.

The engine features electronically controlled gas admission and pilot fuel injection, with functions controlled by an automation system that allows optimal running conditions to be set, independent of ambient conditions or fuel type. The 50DF engine allows use of Wärtsilä's remote diagnosis and dynamic maintenance planning solutions, which the company says offer owners a significant reduction in operating costs by “applying predictive maintenance principles and by optimising engine performance”.

The ship will operate in the Baltic Sea, designated as a Sulphur Emissions Control Area (SECA) with a 0.10% fuel sulphur limit since 1 January. When operating in gas mode Wärtsilä said that SOx and particulate matter emissions from the 50DF engines are negligible, NOx emissions are at least 85% below those specified in the current IMO regulations, and CO2 emissions are 25% less than those of a conventional marine engine running on diesel fuel.

"The Wärtsilä engines are more energy efficient and thus consume less fuel, and for a next generation environmentally sustainable ferry that is what we were especially looking for," said Tarvi-Carlos Tuulik, head of ship management at Tallink Grupp.
