Andrews headed a group of Harland and Wolff workers called the guarantee group, who went on the maiden voyages of their ships in order to observe ship operations and spot any necessary improvements. "Titanic" was no exception, so Andrews and the rest of his Harland and Wolff group travelled from Belfast to Southampton on "Titanic" for the beginning of her maiden voyage on 10 April 1912. During the voyage, Andrews took notes on various improvements he felt were needed, primarily cosmetic changes to various facilities. However, on 14 April, Andrews remarked to a friend that "Titanic" was "as nearly perfect as human brains can make her."
