LNG powered icebreaker Polaris Full scale ice trials of the Aker ARC 130 design
Polaris is the world s first icebreaker powered by a dualfuel power plant capable of using both lowsulphur marine diesel oil (LSMDO) as well as liquefied natural gas (LNG). The 19megawatt (25, 000 shp) icebreaker, the most powerful ever to fly the Finnish flag, is designed for demanding escort icebreaking operations in the Northern Baltic Sea: she can break up to 1. 8 m (6 ft) thick level ice at a speed of more than 3. 5 knots and maintain high average speed during escort operations. Her propulsion system two 6. 5megawatt Azipod propulsion units in the stern and a third 6megawatt unit in the bow gives the 10, 000ton vessel exceptional maneuverability in ice. While designed primarily as an icebreaker, Polaris is also fitted with a builtin recovery system for spilled oil. The innovative, efficient and environmentallyfriendly Polaris is a perfect example of Finnish icebreaking knowhow spanning from design to construction and operation.
