About OSTER

SS Oster is a Norwegian steamship built in 1908 by Christianssands Mekaniske Værksted for the Indre Nordhordlandske Dampskibsselskab to provide a combined passenger and cargo service between Bergen and Osterfjorden in Norway. During World War II she served as a guard ship with both the Royal Norwegian Navy and later with the German Kriegsmarine. Following the war she returned to civilian service and is still in service providing pleasure cruises from Bergen. In 1963 the Bergen deaf priest Ragnvald Hammer wrote the poem " Dar kjem dampen" in honor of the ship. Norwegian folksinger Ivar Medaas later added a tune to this poem.
