On 12 January 1946 she was surrendered to the USSR and integrated into the Baltic Fleet of the Soviet Navy. She was moored in Kronstadt harbour until 1961 where she underwent major repairs and a refit ("e.g." the installation of her first engines) for her missions for the Hydrographic Department of the Soviet Navy. From 1961 to 1965 she undertook many hydrographic and oceanographical surveys for the Academy of Sciences of the USSR in the Atlantic Ocean, the Caribbean, and Mediterranean, and was used as a training vessel for naval cadets. In 1965 she was transferred to the USSR Ministry of Fisheries in Riga to be used as a schoolship for future fishery officers.
