Following the reunification of Germany, Schwerin was deleted on 1 October 1990 and was formally decommissioned from Volksmarine on 2 October. The unified German Navy didn't take over the ship and she was laid up with her pennant number painted over at Peenemünde Naval Base, awaiting her disposal as scrap metal.

Indonesian Navy acquired the ship on 25 August 1993 as part of warship procurement program headed by the then State Minister for Research and Technology, B. J. Habibie, as the Coordinator of the Procurement Team. The procurement program was based on the Presidential Instruction No. 3/1992 issued by President Suharto on 3 September 1992 which aimed to bolster the Navy capabilities. Prior to sailing for Indonesia, she was refitted and demilitarized in Germany. The ship arrived in Indonesia in late 1993 and she was commissioned as KRI Teluk Sibolga (536) on 15 December 1993.
