Interesting Facts About Titanic

The ships were constructed by the Belfast shipbuilders Harland and Wolff, who had a long-established relationship with the White Star Line dating back to 1867. Harland and Wolff were given a great deal of latitude in designing ships for the White Star Line; the usual approach was for the latter to sketch out a general concept which the former would take away and turn into a ship design. Cost considerations were relatively low on the agenda and Harland and Wolff was authorised to spend what it needed on the ships, plus a five percent profit margin. In the case of the Olympic-class ships, a cost of £3 million for the first two ships was agreed plus "extras to contract" and the usual five percent fee.
Harland and Wolff put their leading designers to work designing the Olympic-class vessels. The design was overseen by Lord Pirrie, a director of both Harland and Wolff and the White Star Line; naval architect Thomas Andrews, the managing director of Harland and Wolff's design department; Edward Wilding, Andrews' deputy and responsible for calculating the ship's design, stability and trim; and Alexander Carlisle, the shipyard's chief draughtsman and general manager. Carlisle's responsibilities included the decorations, equipment and all general arrangements, including the implementation of an efficient lifeboat davit design.
On 29 July 1908, Harland and Wolff presented the drawings to J. Bruce Ismay and other White Star Line executives. Ismay approved the design and signed three "letters of agreement" two days later authorising the start of construction. At this point the first ship—which was later to become Olympic—had no name, but was referred to simply as "Number 400", as it was Harland and Wolff's four hundredth hull. Titanic was based on a revised version of the same design and was given the number 401.
