Akademik Sergey Vavilov icebreaker

MS Akademik Sergey Vavilov ("ледокол Академик Сергей Вавилов") is an icebreaking vessel owned by Russia's Academy of Sciences. From 2009 to 2019, the vessel (marketed as "One Ocean Voyager") was seasonally operated as a cruise ship under charter by One Ocean Expeditions (now defunct).

The vessel (IMO number 8507729) is flagged in Russia (MMSI 273414400) and registered in Kaliningrad.

As one of the Russian icebreakers, Akademik Vavilov is among the world’s largest and most powerful polar research vessels. Both Akademik Vavilov and her sister ship Akademik Ioffe were built in Finland for the Russian Academy of Sciences to support its hydro-acoustic ocean research program.

Akademik Vavilov was built by Rauma Shipyard in Finland. The vessel is modern, safe, and ice-strengthened. Public spaces onboard are thoughtfully designed for a variety of needs. Separate lounge and bar areas, as well as a library, offer comfortable spaces for relaxation. A selection of documentaries and films is available in the lounge. The dining room accommodates all passengers in a single seating. Additional facilities include a presentation room, fitness room, massage room, sauna, saltwater plunge pool, hot water spa, and gift shop.

The ship is fully equipped for exploration, including Zodiacs, kayaks, and camping gear. An open-bridge policy allows passengers to visit the navigation room at any time of day.

The Akademik Vavilov itinerary program includes European Arctic expedition cruises to Spitsbergen and Svalbard. She also cruises in Antarctica, departing from Ushuaia (Argentina) and visiting Drake Passage, the Antarctic Peninsula, Elephant Island, South Georgia Island, and the Falkland Islands (UK).
