Key Business Advantages for Shipyards

Dramatically Reduce Infrastructure Capital (CAPEX): Eliminate the multi-million dollar costs of constructing fixed dry docks or installing massive gantry cranes. Airbags convert standard inclined slipways into fully functional haul-out berths.

Minimize Vessel Downtime: Rapid deployment and controlled inflation streamline vessel transfer, shortening turnaround time for cleaning, blasting, plate replacement, and propulsion maintenance.

Maximum Operational Flexibility: Easily transported and stored compactly when deflated. Ideal for temporary project sites, remote shipyards, or handling seasonal repair surges.

Engineering Excellence & Heavy-Duty Performance

Multi-Layer Synthetic Tire-Cord Reinforcement: High-tensile inner cord layers distribute extreme loads evenly across the airbag body, preventing stress concentration and withstanding repeated compression cycles.

Abrasion & Weather-Resistant Outer Compound: Formulated with premium natural rubber to endure friction against concrete slipways, steel hulls, sharp marine growth, and prolonged UV exposure.

Certified Safety & Pressure Stability: Engineered with robust end-fittings and pressure relief mechanisms to maintain stable lifting power during movement, backed by a safety bursting margin (4.5).

Applications & Compatible Vessel Types

Vessel Types: Tugboats, Barges, Dredgers, Offshore Support Vessels (OSVs), Patrol Boats, Passenger Ferries, Fishing Fleets, and Cargo Ships.

Hull Materials: Steel, Aluminum, and Composite/FRP Hulls.

Standard Working Process

Site Preparation: Clear the slipway of debris and ensure a suitable slope.

Airbag Placement: Insert deflated airbags beneath the vessel according to calculated load points.

Controlled Inflation: Gradually inflate airbags to lift the hull clear of the water line.

Winch Pulling: Slowly pull the vessel onto the repair berth using synchronized winches.

Securing & Support: Place structural support blocks for long-term maintenance safety.

FAQ

Q: What are vessel haul-out airbags used for?

A: Vessel haul-out airbags are used to lift vessels from water onto shore and provide support during maintenance, repair, inspection, repainting, upgrading, and conversion projects.

Q: What types of vessels can use haul-out airbags?

A: They can be used for fishing boats, tugboats, barges, ferries, workboats, dredgers, offshore support vessels, patrol boats, and other marine vessels depending on vessel size and operating conditions.

Q: How do I choose the correct airbag size for my vessel?

A: Selection depends on vessel displacement, length, beam, hull shape, lifting requirements, and slipway conditions. The number and size of airbags should be calculated according to the vessel load distribution.

Q: Can haul-out airbags replace a dry dock?

A: Airbags can provide an alternative solution for many vessel maintenance projects, especially where permanent dry dock facilities are unavailable. However, suitability depends on vessel type, size, and site conditions.

Q: How many times can vessel haul-out airbags be reused?

A: The service life depends on operating conditions, maintenance, storage, and correct usage. With proper inspection and maintenance, airbags can be used repeatedly for multiple haul-out operations.

Q: What safety factors should be considered during operation?

A: Operators should select suitable airbags, maintain recommended working pressure, inspect equipment before use, prepare the working surface, and ensure vessel loads are evenly distributed.

Q: Can the airbags be customized for special vessel projects?

A: Yes. Diameter, length, reinforcement layers, pressure rating, valve type, and other specifications can be customized according to project requirements.

Q: What information is needed before requesting a quotation?

A: Please provide vessel type, dimensions, displacement, hull material, application purpose, and operating conditions. This information helps determine the appropriate airbag configuration.
