Versatile Marine Airbags for Restricted Port

As a key product of Qingdao SunKai in the field of restricted port operations, China Versatile Marine Airbags for Restricted Port are developed based on more than ten years of marine equipment R&D and production experience, focusing on the practical needs of restricted port operations. Different from ordinary marine airbags, this product is fully optimized for the characteristics of restricted ports—narrow operation space, shallow water depth, complex terrain and diverse operation types—adopting a compact, lightweight and multi-functional structural design.

It is made of high-strength composite rubber and advanced integral winding technology, fully complies with CB/T3795-2016 industry standards and ISO 14409 international standards, and has passed CCS, BV and other international classification society certifications. It is widely applicable to ship launching, docking, temporary lifting, position adjustment and maintenance of small and medium-sized ships (500-20000DWT) in inland restricted ports, coastal shallow-water ports, small wharves and shipyards with narrow operation spaces, and can also be used for emergency rescue and hull maintenance in restricted water areas, providing reliable versatile airbag solutions for global restricted port operation institutions.

Key Functional Traits

- Compact & Lightweight Structural Design: Adopt a optimized compact structure, with smaller diameter (0.6-1.8m) and adjustable length (3-15m), which is more suitable for narrow operation spaces in restricted ports. The lightweight design (weight reduced by 20% compared with ordinary airbags of the same specification) makes it easy to carry, move and layout, and can be quickly arranged without large hoisting equipment, solving the problem of difficult layout of large airbags in restricted ports.

- Multi-Scenario Versatile Application: Integrate the functions of launching, docking, temporary lifting and position adjustment, realizing one airbag for multiple uses, which can meet the diverse operation needs of restricted ports. It can be used for the launching of small and medium-sized ships in narrow launching sites, the docking buffer of ships in limited berthing spaces, the temporary lifting of ships during maintenance, and the position adjustment of ships in shallow water areas, avoiding the need to purchase multiple types of airbags, and greatly reducing the equipment input cost of users.

- Strong Terrain & Water Depth Adaptability: Optimized for the shallow water depth and complex terrain of restricted ports, the product adopts a low-pressure stable design, with a safe working pressure of 0.08-0.20MPa, which can adapt to shallow water environments (water depth ≥0.5m) without sinking into the sediment. The bottom is designed with anti-slip texture, which can effectively prevent slipping on uneven terrain such as gravel and mud, ensuring stable operation in complex terrain of restricted ports.

- High Strength & Safety Guarantee: The inner layer is reinforced with multi-layer high-strength nylon cord cross winding, combined with high-temperature vulcanization molding technology, the stress distribution is uniform, and the bearing capacity of the Versatile Marine Airbags for Restricted Port is stable and reliable. The safety factor is up to 4.9, which can stably bear the weight of ships up to 20000DWT, and is equipped with a precision pressure monitoring and relief valve, which can accurately control the internal pressure, avoiding safety hazards such as over-inflation, air leakage and explosion during operation.

- Easy Operation & Efficient Deployment: Equipped with a quick inflation and deflation valve, the inflation and deflation can be completed in 15-30 minutes (depending on the specification), which is 30% faster than ordinary airbags. The product is equipped with a portable handle and a positioning device, which is easy to carry and position, and ordinary staff can complete the layout and operation without professional training, greatly improving the operation efficiency of restricted port operations.

Core Competitive Advantages

- Restricted Port-Specific Optimization: Fully tailored for restricted ports, the compact and lightweight design of the Versatile Marine Airbags for Restricted Port solves the core problem of difficult layout of ordinary airbags in narrow spaces. The adjustable length and low-pressure design adapt to the shallow water depth and complex terrain of restricted ports, which is more in line with the actual operation needs of restricted port operators, and the applicability is far superior to ordinary marine airbags.

- Multi-Functional Integration: Integrate launching, docking, lifting and position adjustment functions into one, realizing one airbag for multiple uses, which can meet the diverse operation needs of restricted ports. Compared with purchasing multiple types of airbags separately, it can save 30%-50% of equipment purchase costs, and reduce the storage and maintenance costs of equipment, bringing significant economic benefits to users.

- High Efficiency & Labor Saving: The quick inflation and deflation design and easy operation characteristics greatly improve the operation efficiency of restricted port operations. The layout and operation can be completed by 2-3 staff without large auxiliary equipment, which reduces the labor input by 40% compared with ordinary airbags, and shortens the operation cycle, helping users improve the overall operation efficiency of the port.

- Stable Safety & Strong Adaptability: The high-strength reinforcement structure and precision pressure control system ensure high safety and stable performance. The safety factor of 4.9 is higher than the industry average, and it has passed multiple rigorous tests such as pressure bearing, air tightness and anti-slip performance, effectively avoiding safety hazards during operation. It can adapt to both seawater and fresh water environments, and cope with extreme weather such as high temperature, cold and heavy rain, with strong environmental adaptability.

- Cost-Effective & Flexible Customization: The product has a long service life (up to 13 years), which is 3 years longer than ordinary marine airbags, reducing the frequency of replacement and purchase costs. At the same time, we fully support small-batch customization, and can customize airbags of different diameters, lengths and pressure parameters according to the specific space size, water depth and ship tonnage of the user's restricted port, ensuring accurate matching of user needs.

A: The product adopts a lightweight design and is equipped with a portable handle, so 2-3 ordinary staff can complete the layout, inflation and operation without large hoisting equipment, which is very suitable for restricted ports with limited labor input.

- Q: What is the minimum order quantity? Is small-batch customization supported?

A: The minimum order quantity is 1 piece, and small-batch customization is fully supported. We can customize airbags of different diameters, lengths, working pressures and anti-slip grades according to the specific space size, water depth and ship tonnage of your restricted port, which is very suitable for small restricted ports and small shipyards.

- Q: How to maintain the airbag to extend its service life in complex restricted port environments?

A: After each use, clean the surface sediment, dirt and water stains with clean water in time, dry it naturally, and avoid direct sunlight and high-temperature baking; when storing, place it in a dry and ventilated place, fill it with a small amount of air to keep it slightly expanded, and coat the surface with talcum powder to prevent adhesion; it is recommended to conduct a comprehensive inspection every 4 months, focusing on checking the air tightness and surface wear, and repair it in time if there is slight damage.
