Marine Rubber Airbags High Strength Durable Rubber Long Service Life
Product Overview
Marine Rubber Airbags are advanced marine engineering products designed for ship launching, landing, and heavy lifting operations. Manufactured from high-strength synthetic tire cord layers and premium marine-grade rubber compounds, these airbags provide exceptional load bearing capacity, durability, and flexibility under demanding marine conditions.
Each airbag is constructed with multiple reinforced cord layers arranged at optimal angles to maximize tensile strength and distribute pressure evenly. The outer rubber layer offers excellent resistance to abrasion, seawater corrosion, UV radiation, and aging, ensuring long service life even in harsh coastal environments.
Case Study: Bulk Carrier Launching Project
A mid-sized shipyard in Southeast Asia successfully launched an 8,500 DWT bulk carrier using 18 high-capacity airbags with a diameter of 1.8 meters and length of 16 meters. The vessel measured approximately 118 meters in length with a displacement of over 7,000 tons.
The entire launching process was completed within a few hours without any structural stress or damage to the hull. Compared with building a slipway, the airbag solution reduced infrastructure investment by more than 60%.
