The launching of ships has been largely replaced by the "floating" process. After a ship is ordered for construction, its keel is laid in a drydock. Construction of the ship continues in the dock, usually in the form of prefabricated units that are assembled. After the empty
hull has been substantially completed, sluice gates are opened and the drydock fills with water. The dock gates are then opened and the ship is pulled out by
tugboat to a berth where the remaining construction continues namely
fitting out. This usually includes further construction of the superstructure, attaching of masts and funnels, and the installation of equipment and furnishings. The completed ship will usually return to drydock for installation of other equipment, propulsion parts, and the painting of its hull. The first
superliner to be constructed in this manner was , but the history of "floating" ships rather than "launching" goes back more than one hundred years before that vessel's construction. designed by
Isambard Kingdom Brunel was constructed in drydock and floated on 19 July 1843. She is currently in Bristol, England, United Kingdom. ==Naming ceremony==
