Boat Lift Helper Superior Elasticity Reliable Sealing High Pressure Endurance

Marine Rubber Airbags are a revolutionary solution for launching, landing, and transporting ships, as well as lifting heavy marine structures. Their portable design and high load-bearing capacity allow shipyards and marine contractors to perform operations that once required permanent infrastructure such as dry docks or mechanical slipways.

Constructed with multiple layers of premium natural rubber and high-strength synthetic cord fabric, Marine Rubber Airbags deliver superior elasticity, pressure resistance, and safety. They are reusable, easy to store, and deployable in almost any environment, from sandy beaches to industrial shipyards.

In 2024, a major shipyard in West Africa used 28 Marine Rubber Airbags to launch a newly built 16,000-ton offshore supply vessel. The project site lacked a slipway, but by preparing a reinforced sand path and arranging the airbags properly, the vessel was successfully launched into the ocean within one working day. This operation saved the shipyard millions in potential infrastructure costs and shortened the project timeline by three weeks. The controlled rolling motion and shock absorption of the airbags prevented damage to the hull, demonstrating their reliability and safety for high-value assets.

This case highlights how Marine Rubber Airbags enable complex marine operations in locations without permanent infrastructure, offering an efficient, flexible, and environmentally friendly alternative.

* Other size can be provided follow client's requirements.

• High Load-Bearing Capacity for Large Vessels: Marine Rubber Airbags are designed to handle massive loads, from small fishing boats to vessels exceeding 30,000 tons. Their layered rubber-and-cord construction provides superior tensile strength, enabling them to sustain high working pressures without deformation or failure.
• Superior Durability and Environmental Resistance: Built with abrasion-resistant outer rubber and high-tensile reinforcement layers, Marine Rubber Airbags are engineered to withstand harsh conditions such as saltwater, sharp debris, and fluctuating temperatures.
• Rapid Deployment and Portability: Unlike fixed slipways or floating docks, Marine Rubber Airbags can be transported by truck or container and deployed within hours.
• Safety and Precision Control: The cylindrical design and high-friction surface provide stable rolling and shock absorption, preventing accidents and hull damage.

• Ship Launching and Landing: Enable launching of new vessels and hauling of ships ashore for inspection or repair.
• Heavy Lifting and Transportation: Provide support for moving heavy marine structures, industrial modules, or large pipelines.
• Emergency Salvage and Buoyancy Support: Quickly deployed to refloat sunken vessels or stabilize damaged ships.
• Offshore Pipeline and Structure Installation: Assist in transporting and positioning subsea pipelines or heavy offshore equipment.
