The new generation icebreaker Aker ARC 124 will feature three 8-cylinder Wärtsilä 31 engines. The installation will also include Wärtsilä’s online monitoring of the engines, thereby enabling their operating condition to be closely followed remotely. An additional characteristic of the newly introduced vessel is that it will feature a totally new approach to maintenance.

Icebreaking capacity

  • 1,5 m thick level ice at 2 knots
  • 5 m thick brash ice at 4 knots
  • Operating Arctic conditions: - 50°C

Wärtsilä 31 is recognised by Guinness World Records as the world's most efficient 4-stroke diesel engine.

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), thus making the Wärtsilä 31 a clear leader in this field. 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 project is one of the largest industrial undertakings in the Arctic.

We are confident that this project will be a success because of Wärtsilä’s credibility in the industry, and the positive experience from our long established partnership with this solutions provider. High vessel availability and fuel efficiency are the key winning factors for any ship owner. The Wärtsilä 31 engines will facilitate a significant improvement in vessel operations, making it extremely competitive on the market. This new icebreaker, powered by Wärtsilä 31 engines, will be the most technologically advanced ship of its kind in the whole world.

We are extremely proud to have the opportunity to realize a project involving the newest and most modern domestic icebreaker. This vessel harmoniously combines the operating flexibility and efficiency of the power plant, with high safety standards and good ergonomics of the ship’s equipment. Despite the fact that the Vyborg shipyard has already had orders for six icebreakers, we are confident that this icebreaker, the Aker Arc124 will rightly take its place among the most efficient modern domestic vessels operating in Arctic waters.
