Building

Helsingborgs Varfs AB  [ sv ] built Heidberg in Helsingborg, [1] and launched her on 6 March 1943.[ citation needed ] Her registered length was 277.6 ft (84.6 m), her beam was 41.4 ft (12.6 m), and her depth was 16.2 ft (4.9 m). Her tonnages were 1,714  GRT and 847  NRT. [1]

She had a single screw, driven by a Helsingborgs Varfs three-cylinder triple expansion engine. Steam from its low-pressure cylinder drove an exhaust steam turbine, which powered a compressor. [1] The compressor increased the pressure of steam exhausted from the high-pressure cylinder before it entered the intermediate-pressure cylinder. The pressure also increased the temperature of the steam. This reduced condensation in the intermediate- and low-pressure cylinders, increasing the engine's fuel efficiency and power. [2]

Heidberg and Empire Convention

Heidberg's first owner was Aug. Bolten Wm. Miller’s Nachfolger  [ de ], who registered her in Hamburg. After the German surrender in 1945, Allied forces seized her at Szczecin.

The UK Ministry of War Transport took her over, renamed her Empire Convention, and registered her in London. Her UK official number 180342 and her call sign was GMFM. The MoWT appointed Ellerman's Wilson Line to manage her. [1]

Ernst Thaelmann

Empire Convention was one of a number of ships that the UK transferred to the Soviet Union in February 1946 under the Potsdam Agreement. [3] The Soviet Union renamed her after Ernst Thälmann, [4] who had led the Communist Party of Germany until 1933, and had been executed in Buchenwald concentration camp in 1944.

Ernst Thaelmann became part of the Sakhalin Shipping Company fleet in the Soviet Far East. [5] [6] Lloyd's Register still recorded the ship as extant in 1959. [7] She was deleted from international shipping registers in 1970.[ citation needed ]
