Wärtsilä’s recently introduced 31 engine has been selected to power a state-of-the-art new generation icebreaker currently under construction at the PJSC Vyborg Shipyard.

The new generation icebreaker Aker ARC 124 will feature three 8-cylinder Wärtsilä 31 engines. It is being built on behalf of FSUE Atomflot, the enterprise of ROSATOM, the State Corporation for Atomic Energy, following an order signed in September.

Roger Holm, senior vice president, engines, Wärtsilä Marine Solutions, said: "When the Wärtsilä 31 engine was introduced in June, a new approach to marine power generation was launched. By combining a drastic reduction in fuel consumption, increased power output, and a four-fold extension of normal maintenance intervals, our customers now have the chance to redefine how they operate their vessels to a new level of competitiveness.”

The installation will also include Wärtsilä's online monitoring service thereby enabling the vessel's operating conditions to be followed remotely. An additional characteristic of the newly introduced vessel is that it will feature a totally new approach to maintenance.

The first major service required by the Wärtsilä 31 comes only after 8000 running hours (compared to 2000 running hours for engines of a similar class). This dramatic improvement reduces maintenance costs to a previously unattainably low level, as well as greatly increasing the vessel's uptime availability.

When delivered, the icebreaker will serve the Yamal LNG project in Sabetta, located northeast of the Yamal peninsular in Russia.

The Wärtsilä 31 engine is available in 8 to 16 cylinder configurations and has a power output ranging from 4.2 to 9.8 MW, at 720 and 750 rpm.

It has been acknowledged by Guinness World Records as being the world's most efficient 4-stroke diesel engine.
