The recently introduced 4-stroke diesel engine, Wärtsilä 31, has been selected to power a new generation icebreaker currently under construction at the PJSC Vyborg Shipyard. The ship is being built on behalf of FSUE Atomflot, the enterprise of ROSATOM, the State Corp. for Atomic Energy. The order was signed in September.
When delivered, the icebreaker will serve the Yamal LNG project in Sabetta, located northeast of the Yamal peninsular in Russia. The new vessel will operate in temperatures as low as minus 50°C.
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. 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).
The Wärtsilä 31 is the first of a new generation of medium speed engines. It is available in 8 to 16 cylinder configurations and has a power output ranging from 4.2-9.8 MW, at 720 and 750 rpm.
