Product Description
Marine Rubber Airbags for Ship Launching
Marine Rubber Airbags are premium marine engineering solutions designed for safe and efficient ship launching, vessel retrieval, and heavy marine equipment transport. Constructed with multiple layers of high-strength synthetic tire cord reinforcement embedded within marine-grade natural rubber, these airbags provide superior load capacity, elasticity, and durability.
Product Overview
The internal cord arrangement is optimized for tensile strength and pressure distribution, allowing the airbags to maintain structural stability under dynamic loads and high internal pressures. The outer rubber surface is formulated to resist abrasion, puncture, UV radiation, and seawater corrosion, ensuring long-term performance even under harsh marine environmental conditions.
Marine Rubber Airbags come in diameters ranging from 0.7 meters to 2.5 meters and lengths up to 24 meters, with custom sizes available to meet specific project demands. When inflated, the airbags form a flexible rolling support system that evenly distributes vessel weight and allows smooth movement during launching or landing operations.
Case Study: West African Shipyard
A medium-sized shipyard in West Africa successfully launched a 5,000 DWT container vessel using 16 Hongruntong Marine Rubber Airbags. The vessel measured approximately 110 meters in length with a displacement exceeding 5,000 tons. The engineering team configured airbags with a diameter of 1.7 meters and length of 14 meters arranged along the keel and bilge.
The launch was completed successfully in a single day without structural damage. The shipyard reported reduced preparation time and significant cost savings compared to traditional launching methods. The airbags were subsequently reused for multiple vessel launches, demonstrating long-term durability and operational efficiency.

Frequently Asked Questions
How do I determine the number of airbags needed for a vessel?
Engineers calculate required airbag quantity based on vessel weight, hull shape, ground slope, and airbag dimensions to ensure even load distribution and safe operation.
Can these airbags be used repeatedly?
Yes, with proper handling, maintenance, and inspection, high-quality marine airbags can be used multiple times for many launching and landing operations.
What equipment is required to inflate the airbags?
Airbags are typically inflated using industrial air compressors with pressure gauges to control the internal pressure accurately for safe operations.
How should airbags be stored to extend lifespan?
After use, airbags should be cleaned, dried, and stored in a shaded, dry area away from sharp objects and direct sunlight to preserve material integrity.
Are Hongruntong Marine Rubber Airbags certified?
Yes, they meet recognized international marine engineering standards including ISO certifications, ensuring safety, reliability, and consistent performance under heavy loads.
