The Grand Fleet swept the central North Sea on 17–19 May and 29–31 May without encountering any German vessels. "Temeraire" was refitted at Devonport in mid-1915 and rejoined the 4th BS in August. On 2–5 September, the fleet went on another cruise in the northern end of the North Sea and conducted gunnery drills. Throughout the rest of the month, the Grand Fleet was performing numerous training exercises before making another sweep into the North Sea on 13–15 October. Almost three weeks later, "Temeraire" participated in another fleet training operation west of Orkney during 2–5 November.
