On March 14 she started its maiden voyage from Cuxhaven to New York.
In August 1914 the vessel was interned at New York, and in April 1017 the crew damaged the engines and boilers out of fear for seizure by the US authorities.

On July the 4rth 1923 she made her first voyage from New York-Southampton
