Memel was a 1,102 GRT cargo ship that was built in 1925 as Reval by Schiffs-und Dockbauwerft Flender AG, Lübeck, Germany for German owners. A sale in 1934 saw her renamed Memel. She was seized by the Allies in May 1945, passed to the Ministry of War Transport (MoWT) and was renamed Empire Constellation. In 1946, she was transferred to the Soviet Union and renamed Ivan Sechenov.
