SS Otsego was a cargo liner that was launched in Germany in 1901 as Prinz Eitel Friedrich. The USA seized her in 1917 and renamed her Otsego. In 1919 she served in the United States Navy as USS Otsego (ID-1628). She spent the 1920s and 30s in merchant service as Otsego. In 1941 she became the United States Army ship USAT Otsego. In 1945 she was transferred to the Soviet Union, which renamed her Ural. In 1947 she may have been renamed Dolinsk. She was either hulked or scrapped in 1955.

The Hamburg-Amerikanische Packetfahrt-Actien-Gesellschaft (HAPAG), known in English as the Hamburg America Line, was a transatlantic shipping enterprise established in Hamburg, in 1847. Among those involved in its development were prominent citizens such as Albert Ballin, Adolph Godeffroy, Ferdinand Laeisz, Carl Woermann, August Bolten, and others, and its main financial backers were Berenberg Bank and H. J. Merck & Co. It soon developed into the largest German, and at times the world's largest, shipping company, serving the market created by German immigration to the United States and later, immigration from Eastern Europe. On 1 September 1970, after 123 years of independent existence, HAPAG merged with the Bremen-based North German Lloyd to form Hapag-Lloyd AG.
