Safety Airbags for Large Tonnage Vessels

As a core product of Qingdao SunKai factory in the large-tonnage marine airbag field, Safety Airbags for Large Tonnage Vessels are developed based on 18 years of marine equipment R&D experience and hundreds of large-tonnage vessel operation cases, focusing on solving the industry pain points of "insufficient load-bearing, easy distortion, and poor safety" in traditional large-tonnage airbags. It is widely applicable to large-tonnage ships (15000-80000DWT) and marine structures, covering scenarios such as large ship launching, docking buffer, temporary lifting during hull maintenance, emergency salvage of grounded large vessels, and moving of large concrete caissons and offshore wind power components. It is especially suitable for large shipyards, deep-water terminals, and marine engineering sites, providing reliable safety support for global large-tonnage marine operations

Key Functional Characteristics

- Ultra-High Load-Bearing & Anti-Twist Structure: The product effectively avoids distortion and twisting during heavy load operation, which is a common problem of ordinary large-tonnage airbags. The safety factor is as high as 5.5, the maximum working pressure reaches 0.40MPa, and a single airbag can stably bear a load of up to 1200 tons, which can meet the operation needs of large-tonnage vessels up to 80000DWT.

- Intelligent High-Pressure Control System: Equipped with a dual-mode intelligent pressure monitoring and regulation system, which can real-time monitor the internal pressure of the airbag with an accuracy of ±0.01MPa. It supports automatic pressure relief, supplementary inflation, and overpressure/underpressure alarm, and can be connected to the on-site operation control platform to realize remote monitoring and operation. It effectively avoids safety hazards such as airbag burst and deformation caused by unstable pressure during large-tonnage load operation, ensuring safe and stable operation even in complex marine environments.

- Wear-Resistant & Anti-Impact Protection: The outer layer of the Safety Airbags for Large Tonnage Vessels is made of special high-wear-resistant marine rubber (thickness up to 15mm), added with anti-aging and anti-UV additives, which can resist scratches from sharp objects, marine debris, and concrete surfaces, and withstand strong impact during ship launching and docking. The surface is designed with a wear-resistant convex texture, which enhances friction and avoids slipping between the airbag and the hull or ground, ensuring stable operation during heavy load rolling.

- Large-Scale Adaptation & Flexible Deployment: Optimized for the size and weight characteristics of large-tonnage vessels, the product has a diameter range of 1.8-3.0m and an adjustable length of 15-30m, which can be flexibly combined according to the hull size and operation needs. It is equipped with a heavy-duty lifting ring and a positioning guide device, which can be quickly deployed with the assistance of hoisting equipment, and the inflation and deflation can be completed in 30-60 minutes (depending on the specification), improving the efficiency of large-tonnage vessel operations.

- Corrosion-Resistant & Long-Service Life: The inner layer adopts high-density corrosion-resistant airtight rubber, which can resist corrosion from seawater, marine organisms, and chemical agents, ensuring good air tightness in long-term marine operations. The overall structure is optimized for anti-fatigue design.

Core Competitive Advantages

- Ultra-High Load-Bearing & Anti-Twist Advantage: Different from ordinary large-tonnage airbags that are prone to twisting and insufficient load-bearing, this product adopts an muilt-layer ultra-high-strength composite structure and anti-twist design, with a safety factor of 5.5 and a single airbag bearing capacity of up to 1200 tons, which is 30% higher than the industry average.

- Intelligent High-Pressure Safety Protection: Equipped with a dual-mode intelligent pressure control system, which realizes real-time monitoring, automatic regulation, and remote operation, avoiding safety hazards caused by manual operation errors. The system has passed strict marine environment tests, and can work stably under high temperature, high humidity, and strong wind conditions, ensuring the safety of large-tonnage vessel operations.

- Large-Scale Adaptation & Flexible Combination: The product has a wide range of specifications, with a diameter of 1.8-3.0m and an adjustable length of 15-30m, which can be flexibly combined according to the size and weight of large-tonnage vessels and marine structures. It can replace traditional slipways and trolleys, reducing infrastructure investment and realizing flexible operation in different sites.

- Efficient Deployment & Labor Saving: The heavy-duty lifting ring and positioning guide device are matched with quick inflation and deflation valves, which can complete the deployment and inflation of airbags in a short time with the assistance of hoisting equipment. The operation can be completed by 3-4 professional staff, which reduces labor input by 35% compared with ordinary large-tonnage airbags and greatly improves operation efficiency.

- Customization & Cost-Effective: Support personaliz for Safety Airbags for Large Tonnage Vessels.
