Polaris is a Finnish icebreaker. Built in 2016 by Arctech Helsinki Shipyard, she is the most powerful icebreaker ever to fly the Finnish flag and the first icebreaker in the world to feature dual-fuel engines capable of using both low-sulfur marine diesel oil (LSMDO) and liquefied natural gas (LNG). Polaris was initially ordered by the Finnish Transport Agency, but the ownership was transferred to the state-owned icebreaker operator Arctia after delivery.
