MV Ortelius is an ice-strengthened vessel currently employed for expedition-style polar cruises by owner and operator Oceanwide Expeditions.

She was originally named Marina Svetaeva and was built in Gdynia, Poland, in 1989 as a special-purpose vessel for the LLC RN-Sakhalinmorneftegaz.

In December 2007, she was chartered by Aurora Expeditions of Sydney, Australia, as a cruise ship in the Arctic and Antarctic seas.

Marina Svetaeva was acquired in 2011 by the Dutch company Oceanwide Expeditions, based in Vlissingen, Netherlands.

A highlight of that particular season was a successful expedition to Snow Hill Island, where passengers were transported by helicopter to a colony of emperor penguins and their chicks.
