Oceanic Steam Navigation Co
1869 Thomas Henry Ismay, soon after he had purchased the White Star Line, formed a partnership with an old friend and fellow-apprentice, William Imrie, the Oceanic Steam Navigation Co; this was backed by Gustavus Schwabe, a Liverpool merchant, on condition that all their ships would be ordered from Harland and Wolff (a shipbuilding venture involving Schwabe's nephew, Gustav Wilhelm Wolff, and Edward James Harland - Harland and Wolff).
The 2 friends had already formed a joint company Ismay, Imrie and Co which became a subsidiary division of the Ocean Steam Navigation Company. Ismay ran the steamers under the White Star flag. Imrie ran the sailing vessels under the name of North West Shipping Co.
