"Yavuz" escorted the members of the Ottoman Armistice Commission to Odessa on 30 March 1918, after the Treaty of Brest-Litovsk was signed. After returning to Constantinople she sailed in May to Sevastopol where she had her hull cleaned and some leaks repaired. "Yavuz" and several destroyers sailed for Novorossiysk on 28 June to intern the remaining Soviet warships, but they had already been scuttled when the Turkish ships arrived. The destroyers remained, but "Yavuz" returned to Sevastopol. On 14 July the ship was laid up for the rest of the war. While in Sevastopol, dockyard workers scraped fouling from the ship's bottom. "Yavuz" subsequently returned to Constantinople, where from 7 August to 19 October a concrete cofferdam was installed to repair one of the three areas damaged by mines.
