Keel laying

Keel laying is the formal recognition of the start of a ship's construction. It is often marked with a ceremony and is one of the four principal milestones in a ship's life; the others being launching, commissioning, and decommissioning. Traditionally, it refers to the laying down of the keel, which is the backbone of the vessel, running along the bottom from the bow (front) to the stern (back). In modern shipbuilding, the keel laying represents the placement of the first modular component or the first block in the construction dock or on the slipway. This event is significant as it marks the birth of the ship and is often recorded with the ship's official number and date of keel laying.

History

The tradition of keel laying dates back to the times when ships were made of wood. The keel was the first part of the ship to be constructed. It served as the foundation upon which the rest of the ship was built. The importance of the keel stems from its structural role as the spine of the vessel, providing a base for constructing the rest of the ship's frame.

Modern Practices

In contemporary shipbuilding, the concept of a single, long keel is less relevant due to advances in design and construction methods. Ships are now often built in sections, in different locations, and then assembled. Despite this, the keel laying ceremony remains an important tradition. It usually involves placing a newly minted coin under the keel for good luck, a practice that dates back to ancient times.

Significance

The keel laying is not only a ceremonial milestone but also a critical phase in shipbuilding. It signifies the transition from the design and planning stages to the physical construction of the vessel. The event is often attended by dignitaries, naval officers, and representatives from the shipbuilding company, and it may include the welding of a commemorative plaque or the placement of memorabilia within the ship's structure.
