Flexible & Cost-Effective Marine Launching & Transfer Solution

Slipway Ship Launching Rubber Airbags are high-performance pneumatic lifting devices engineered to support vessel launching, haul-out, and heavy-load movement using controlled compressed air technology.
By creating rolling support beneath the vessel hull, these marine airbags allow shipyards to move vessels safely into the water-eliminating the need for expensive permanent launching infrastructure, fixed tracks, or complex dry-dock systems.

Key Advantages for Shipyards & Marine Contractors

Dramatically Lower CAPEX: Replaces permanent civil infrastructure with a flexible, temporary rolling system, freeing up shipyard capital and space.

Exceptional Dynamic Load Support: Engineered to withstand extreme pressure, heavy deformation, and uneven weight distribution during dynamic rolling operations.

Adaptable to Diverse Slipways: Performs reliably on various slipway surfaces (concrete, packed soil, or sand) and accommodates different hull shapes and slope angles.

Long Service Life: High-grade outer rubber combined with synthetic tire-cord layers offers superior resistance to abrasion, UV radiation, and seawater corrosion.

Engineered Multi-Layer Structure

Layer	Structure	Key Function
Outer Rubber	Heavy-Duty Elastomer	Protects internal layers against mechanical abrasion, sharp debris, and marine environments.
Reinforcement	High-Tensile Synthetic Tire Cords	Provides burst resistance, structural stability, and primary load-bearing capacity.
Inner Rubber	Airtight Synthetic Compound	Seals internal compressed air for long-term pressure retention.

Primary Applications

New Vessel Launching: Versatile launching method for cargo ships, tugboats, barges, tankers, and workboats (supporting vessels up to 100,000+ DWT).

Vessel Haul-Out & Maintenance: Pulls ships out of the water onto slipways for dry-dock repairs, hull painting, and structural overhauls.

Marine Heavy Transport: Relocates caissons, floating structures, and offshore steel modules in heavy engineering projects.

FAQ

Q: What are Slipway Ship Launching Rubber Airbags used for?

A: Slipway Ship Launching Rubber Airbags are used for lifting, supporting, transferring, and launching vessels from slipways into water. They are commonly applied in shipyards, repair yards, and marine engineering projects.

Q: How do ship launching rubber airbags work?

A: The airbags are installed under the vessel hull and inflated with compressed air. The expanding airbags generate lifting force, allowing the vessel to move along the slipway through rolling support.

Q: What types of vessels can use ship launching airbags?

A: They can be used for cargo ships, fishing boats, tugboats, barges, workboats, offshore vessels, and other marine structures depending on project requirements.

Q: How do I select the correct ship launching airbag size?

A: Selection depends on vessel weight, hull dimensions, launching conditions, required lifting height, and safety requirements. The number and specifications should be calculated based on the actual project.

Q: Are ship launching airbags reusable?

A: Yes. With proper operation, inspection, and storage, launching airbags can be reused for multiple ship launching projects.

Q: What materials are used for ship launching airbags?

A: They are generally manufactured with reinforced rubber and synthetic tire cord layers. This structure provides flexibility, strength, and resistance against pressure during launching operations.

Q: Can ship launching airbags be customized?

A: Yes. Diameter, effective length, reinforcement layers, and other specifications can be customized according to vessel size and launching conditions.
