Boat Launching Balloon Inflatable Airbags Inflatable Balloons for Ship Launching
Description
A ship launching balloon is a large and inflatable device that is utilized to launch ships from dry docks or shipyards. The balloons offer an alternative to conventional ship launching methods such as building inclined planes or using slipways. Typically, ship launching balloons are made from highly durable and tear-resistant materials like natural rubber. They are usually filled with compressed gas or air, which slowly inflates the balloon and lifts the ship off its cradle or supports before finally releasing it, allowing it to slide gently into the water.
 The use of ship launching balloons provides certain advantages, including portability, ease of use, and minimal environmental impact compared to traditional methods. Additionally, they provide greater control and precision during the launch, decreasing the possibility of harm to the ship or its surroundings. Ship launching balloons have been used for decades in shipbuilding across the globe, proving to be a reliable and effective approach to launch ships into the water.
