F Schichau GmbH built Masuren at its Danzig shipyard as yard number 1349. Her launch date unrecorded but she was completed in October 1935. Schichau made her engines at its works in Elbing. Masuren was powered by a four-cylinder compound steam engine plus low-pressure steam turbine. Together they were rated at 358 NHP[1] and gave her a speed of 12kn.
Her first owner was Kohlen-Import & Poseidon Schiffahrt AG and she was registered in Königsberg.[2] Masuren served for ten years until she was seized in Copenhagen by the United Kingdom at the end of the Second World War in 1945. Her port of registry had been changed to Nordenham in that year.[2] Ownership passed to the Ministry of War Transport, who renamed her Empire Annan,[3] and contracted Crosby, Sons & Co to manage her.[2] She was registered in London.[4]
