The ship was built by Stocznia Szczecinska im A Warskiego in Szczecin, Poland in 1981 and operated as Konstantin Simonov in the Baltic Sea from construction, undergoing a refit in 1988.

Until 2010, the ship was owned by Israeli Mano Cruise (after a refit in 2001) and operated in the eastern Mediterranean Sea under the name The Iris, during which time she was registered in Malta.

[7][8][9] On 8 January 2014,[10] the ship was sold and renamed Ocean Endeavour with a capacity of 199 passengers.

[6] The vessel has operated in the northern summer season on the east coast of Canada, Greenland and the Canadian Arctic by Adventure Canada, and in the southern summer season to Antarctica from Ushuaia by a joint venture between Intrepid Travel and Chimu Adventures.

On 5 September 2019, passengers of Adventure Canada on Ocean Endeavour were the first members of the public to visit the site of the wreck of HMS Erebus, one of the two ships of the ill-fated Franklin expedition which aimed to traverse the North-West Passage through the Canadian Arctic Archipelago.
