Inflatable Marine Airbags are high-performance marine equipment designed to support efficient ship launching, vessel docking, and heavy structure movement in modern shipyards. Constructed using multiple layers of heavy-duty synthetic tire cord fabric reinforced with industrial-grade rubber, they provide outstanding mechanical strength and durability.
Standard specifications typically range from 0.6m to 2.2m in diameter and up to 22m in length, with customizable options for different shipyard requirements. These airbags function as flexible load-bearing rollers that enable controlled movement of vessels from dry land into water, evenly distributing pressure along the hull to minimize stress concentration.
A busy commercial shipyard in East Asia handling bulk carriers and cargo vessels implemented Inflatable Marine Airbags as a primary launching system to improve efficiency while reducing operational costs.
Using 20 airbags with 1.3-meter diameter and 18-meter length for vessels ranging from 5,000 to 10,000 DWT, the shipyard achieved:
