MV Ocean Adventurer is an ice-capable expedition cruise ship operating commercial voyages to both polar regions, with Quark Expeditions of Seattle, Washington, United States.

MV Lyubov Orlova was a 1976 Yugoslavia-built ice-strengthened Maria Yermolova-class cruise ship, which was primarily used for Antarctic cruises. After being taken out of service in 2010, she sat in St. John's, Newfoundland, Canada for two years. Decommissioning was fraught with problems and the ship eventually became a floating derelict in the North Atlantic Ocean in 2013. She is believed to have sunk.
