How Newly Built Ships are Launched into water (Video)


If you are wondering how great giant ships are built and put into the water, here are some videos you may love to see.

There are three principal methods of conveying a new ship from building site to water.

End On Launch

The oldest, most familiar, and most widely used is the end-on launch, in which the vessel slides, usually stern first, down an inclined slipway.

Side Launch

In side launch, the ship enters the water broadside, came into 19th-century use on inland waters, rivers, and lakes, and was more widely adopted during World War II.

You may wonder why ships are launched in this risky way, but it seems that this method of launching a newly built ship is the simplest solution of moving the vessel to water after construction in the dry land. This method is the most practised and virtually remains unchanged for thousands of years.

As the ship is launched, it glides over the greased timber it its own weight and lands into the water and gets into a floating position

Float Out

The third method is float-out, used for ships that are built in basins or dry docks and then floated by admitting water into the dock.

Modern ships are built and launched in Float-Out method. After a ship is ordered for construction, its keel is laid in a dry-dock. Construction of the ship continues in the dock, usually in the form of prefabricated units that are assembled.

After the hull has been substantially completed, sluice gates are opened and the dry-dock fills with water. The dock gates are then opened and the ship is pulled out by tugboats to a berth where the remaining construction continues. 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 dry-dock for installation of other equipment, propulsion parts, and the painting of its hull.
