Product Description

Rubber Marine Airbag for Ship Launching and Landing

Marine Rubber Airbags

The purpose of Marine rubber airbag is to make use of low-pressure air charging and large-area bearing function to complete the airbag discharging or launching operation on the ship.
Taking advantage of the characteristics of low inflating pressure, large bearing area and easy rolling after large deformation of the airbag, the ship is first lifted from the pier with a lifting airbag, then placed on the rolling airbag, and then the ship is slowly moved into the water by towing the ship and the rolling airbag with steel cables.
The air bag is made of high strength fabric and rubber composite material, which is easy to repair when damaged.
This method is simple and flexible, and can be applied to the launching area with different slope and soil quality. It has been used for launching small barge, tugboat and flat bottom boat with dead weight below 200T for some small inland river shipyards in China.
The production and application of Marine airbags are mainly carried out according to two industry standards: CB/T3795 Airbags for Ships and CB/T3837 Technology Requirements for Airbags for Ships.
Marine launching airbag is an innovative product with independent intellectual property rights in China. Its application is less limited by site and does not require large mechanical equipment. Therefore, it can shorten the engineering cycle and save a lot of money.
After more than 20 years of development practice, it has been proved that this product is safe and efficient, green and environmental protection, flexible and so on.
At present, it has been widely used in heavy lifting and transportation, ship upstream and downstream, caisson lifting and transportation, other heavy lifting, underwater installation works to help buoy and other fields.
Marine rubber airbags are now popular with shipyards, ship owners and Marine supplies companies.

Airbag application field

Upper and lower water
After more than 20 years of practice, launching ships have developed from flat boats weighing dozens of tons to large ships weighing tens of tons. Practice has proved that the technology of airbag upstream and downstream is safe and reliable.
At present, this technology has been recognized by shipbuilding industry and port construction industry at home and abroad, and airbag launching technology has been promoted in the United States, Europe and Southeast Asia and other countries.
Heavy handling
At present, Marine airbag is widely used in caisson jacking, transport, launching and other fields in port construction.
Our famous "Nanhai No. 1" sunken ship salvage project is to use Marine airbags to complete the landing of caisson and move into the "Crystal Palace" work.
Buoyancy aid salvage
Marine airbag has been widely used in the rescue of stranded ships and other areas of floating salvage because of its high buoyancy and strong load-bearing capacity.

Marine Airbag Production Process:

1.Raw Material Preparation
2.Rolling Out for Airbag Body
3.Moulding two ends of the airbags
4.Air-inflation
5.Stretch-wrap, Integrated Cross Intertwine the Synthetic Cord Reinforced Rubber Layers
6. Vulcanizing
7.Fittings Assembling
8.Air-tightness Test
9.Surface Protection
10.QC Test as per GB/T3795-1996 and ISO 14409 International Standerd / Third-party Inspection
11.Packing & Delivery
Maintenance of Marine Airbags

1. When the air bag is not in use for a long time, it should be washed and dried, filled with talcum powder and coated externally.
Airbag maintenance should be carried out in a dry, ventilated room away from the light source.
Airbags should be stored to avoid stretching, compression and deformation.
2. Keep the air bag away from heat source.
3. The air bag shall not be in contact with acids, bases, fats and organic solvents.

Repair of Marine Airbags

The damage forms of marine airbags can be generally divided into longitudinal cracks (cracks extending along the length of airbags), transverse cracks (cracks extending along the circumference), and nail holes (including disc-shaped damages with a diameter of less than 10 cm).
