MV Wotan was a 5,703 GRT tanker that was built in 1913 by Reiherstieg Schiffswerft & Maschinenfabrik, Hamburg, Germany.

Her diesel engine was replaced by a triple expansion steam engine and she was renamed SS Gianna M. In 1941, she was captured by HMS Hilary, passed to the Ministry of War Transport (MoWT) and was renamed SS Empire Control.

She was sold into merchant service in 1948 and renamed SS Kleinella, serving as a storage hulk at Gibraltar until 1953, when she was scrapped.

[3] Wotan was built for the Deutsche-Amerikanische Petroleum Gesellschaft, Hamburg,[1] one of the earliest motor vessels constructed.

She was operated under the management of the Standard Oil Co. Wotan departed London on 22 December 1920 bound for New York, but suffered engine trouble on the voyage.

She was fitted with a triple expansion steam engine and renamed Gianna M.[1] The ship was now assessed at 5,719 GRT, 3,396 NRT.

On 11 May 1941, Gianna M was captured by the Armed Merchant Cruiser HMS Hilary whilst attempting to reach Bordeaux, France.
