pu was a Finnish state-owned steam-powered icebreaker built by Howaldtswerke in Kiel, Germany, in 1899. Initially owned by a private shipping company founded by shipowners from the Finnish city of Turku and known as Avance, she was later purchased by the Finnish Board of Navigation and her name was translated into Finnish. Apu remained in service until 1959, when she was replaced by the new diesel-electric Murtaja.
