Wärtsilä will supply five dual-fuel engines

Wärtsilä reports that a new icebreaker for the Finnish Transport Agency will be powered by dual-fuel engines capable of operating on both LNG and low sulphur diesel fuel.

The full scope of supply includes five Wartsila DF engines: one 8-cylinder 20DF, two 9-cylinder 34DF, and two 12-cylinder 34DF.

The vessel is designed to move continuously through 1.6m thick ice, and to break a 25m channel in 1.2m ice at a speed of 6 knots. Open water service speed is specified as 16 knots minimum. As well as icebreaking, it will perform oil spill response operations and emergency towing in winter and summer, enabling year-round operation in the Baltic region.

Wärtsilä says that its record in dual-fuel engine technology was a crucial factor in the award of the contract, as was the high power output per cylinder.   

"We are the industry leaders in gas fuelled vessel equipment, and are proud to supply the world's first LNG powered icebreaker with engines powerful enough to meet the customer's requirements. The combination of ice breaking power and environmental sustainability is difficult to achieve, but our dual-fuel engine technology has the capabilities needed," said Aaron Bresnahan, vice president, sales, Wärtsilä Ship Power.

"The new icebreaker features the highest technology and will be built especially to operate in the demanding winter conditions of the northernmost Baltic Sea. By being able to use LNG fuel, the vessel will be the most environmentally friendly icebreaker ever built," added Esko Mustamäki, MD of Arctech Helsinki Shipyard.

The ship is being built at Arctech Helsinki Shipyard for launch in late 2015, and is thought to be the world’s first LNG-fuelled icebreaker.
