Keel laying
Laying the keel, or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship.
Keel laying is one of the four specially-celebrated events in the life of a ship; the others are launching, commissioning, and decommissioning.
In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are now largely built in a series of pre-fabricated, complete hull sections rather than being built around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's life, although modules may have been started months before that stage of construction.〔(【引用サイトリンク】title=Ship Building Milestones )〕〔(【引用サイトリンク】title=Australia: Austal Holds Keel-Laying Ceremony... )〕
==Traditions==
Keel-related traditions, from the times of wooden ships are said to bring luck to the ship during construction and to the captain and crew during her later life. They include placing a newly minted coin under the keel and constructing the ship over it, having the youngest apprentice place the coin, and when the ship is finished, presenting the owners with the oak block on which the keel is laid.〔(【引用サイトリンク】title=Keel laying ceremony for two Ro-Ro special ships for DFDS A/S )〕〔(【引用サイトリンク】title=Aker Philadelphia Shipyard Holds Ceremonial Keel Laying )〕
