SS Jagiełło

The ship was 117.25 metres (384 ft 8 in) long, with a beam of 15.98 metres (52 ft 5 in) and a depth of 6.22 metres (20 ft 5 in). She was assessed at 6,133 GRT, 3,139 NRT.[1]

The ship was powered by two 3-cylinder triple expansion steam engines, which each had cylinders of 60 centimetres (23 ¹⁄₂ in), 90 centimetres (35 ⁷⁄₁₆ in) and 159 centimetres (62 ⁵⁄₈ in) diameter by 100 centimetres (39 ³⁄₈ in) stroke. The engines drove twin screw propellers via low pressure turbines and a double reduction drive. Built by Blohm+Voss,[1] they could propel the ship at 15 knots (28 km/h).[2]

The ship was built in 1939 as Doğu at the Blohm und Voss shipyard in Hamburg for the Turkish government organisations Denizbank and Denizyollari Idaresi.[3] Yard Number 520, Doğu was launched on 15 March 1939, the first of three sister ships, the others being Egemen and Savas, and completed on 31 August.[4][5] The ship had not been commissioned when war broke out in September 1939, was taken over by Germany, with Deutsche Afrika-Linien appointed managers, and renamed Lüderitzbucht.[6] In 1940 the ship was taken over by the Kriegsmarine, who used it as a residential hulk at Flensburg, renaming it Duala in early 1945.[6][7]

Pyotr Velikiy at Odessa in 1964

Still moored at Flensburg in May 1945, Duala was taken as prize by British forces and transferred to the Ministry of War Transport under the name Empire Ock.[6] The United Kingdom Official Number 180588 and code letters GJZD were allocated. The ship's port of registry was London and it was operated under the management of City Line Ltd.[1] In the following year Empire Ock was allocated to the Soviet Union as part of German war reparations. It was given the name Pyotr Velikiy (Russian: "Пётр Великий", Peter the Great) and registered at Leningrad to the Ministry of the Maritime Fleet.[4][6][nb 1] The conversion back to a passenger ship proved to be too expensive, so in 1947 it was given to Poland.[9]

After a year-long renovation in the Genoa shipyard, the ship was given the name Jagiełło and Gdynia-America Line colours, but never came to Gdynia. It was the only large passenger ship from the Blohm & Voss shipyard, operated under the Polish flag. For a year she sailed, in cooperation with the Italian shipowner company Cosulich and with a largely Italian crew (only a few officers and specialists were Polish), on the Genoa-Central America-Cuba-Lisbon route.[9] Due to the unprofitable nature of the venture, the ship returned (probably free of charge) to the Soviet flag and to the name Pyotr Velikiy in 1949.[2][7] It was owned by Black Sea Shipping Company, registered at Odessa, with the Soviet Register number M-2381 and code letters UVSA.[4]

Pyotr Velikiy was operated (alongside Gruziya, formerly the Polish MS Sobieski), on Black Sea passenger routes, principally between Odessa, Sochi and Batumi.[7][9] The ship was withdrawn from service and arrived for demolition by I M Varela Davalillo at Castellón de la Plana, Spain on 20 November 1973.[4][10]
