After her completion "Petr Veliky" was assigned to the Gunnery Training Detachment through 1917. A number of sources report that she was renamed by the Soviets as "Respublikanets (Republican)" or "Barrikada (Barricade)", but this is not confirmed by the post-Cold War sources used by McLaughlin. That year she was assigned as a depot ship for submarines at Kronstadt and later Helsinki. The Treaty of Brest-Litovsk required the Soviets to evacuate their naval base at Helsinki in March 1918 or have their ships interned by newly independent Finland even though the Gulf of Finland was still frozen over. "Petr Veliky" reached Kronstadt in April in what became known as the 'Ice Voyage'. The ship was hulked on 21 May 1921 and used to store mines. She was renamed "Blokshiv Nr. 1" on 4 December 1923 and forced aground in shallow water by autumn floods in September 1923. She was not refloated and repaired until 5 October 1927. On 1 January 1932 she was renamed to "Blokshiv Nr. 4", and to "BSh-3" on 16 May 1949, by which time she was being used as a barracks ship at Kronstadt. The ship was stricken on 18 April 1959 and subsequently scrapped.
