One of the most crucial steps in the construction of a ship is the launch of the vessel. An integral part of the ship launching process, the ship launching slipway is a structure that consists of a sloped path leading from the shipyard to the water. It has been extensively used for launching freshly constructed or repaired ships.
There are some types of ship launch such as Gravitational type launching, Floating-out type launching, Mechanical Type launching and Airbag launching.
Gravitational type launching
One of the earliest types of launching systems is the longitudinal lubricated slideway launching. With this system, the ship launches itself into the sea using a ship launch roller slideway. In order to facilitate sliding, oil or wax is utilized. The main benefit of this procedure is that it just requires basic tools and can be applied to vessels of various types and tonnages.
Floating- Out Type Launching
Ships built at dry docks are launched using the floating out style of launching, which involves filling the dock with water. Technically, this is not the process for launching a ship. The floating-out type launching mechanism is a fast, reliable, and secure ᴍᴇᴛʜod. Shipbuilders are the ones who use this type of approach the most frequently, despite the significant initial outlay.
Air bags Launching
Using air bags to launch ships into the water is a cutting-edge and secure ᴍᴇᴛʜod. Usually cylindrical in shape, these airbags have hemispherical heads on both ends. They have a high load capacity and are constructed of reinforced rubber layers. All shapes and sizes of vessels can simply be employed with this technique.
