Marine salvage airbags are designed based on ship launching airbags. Marine salvage airbags are the toughest salvage bags. It can be used for salvage and flotation as floating salvage pontoons. Marine rubber airbags can be used to salvage the shipwreck, rescue the floating bridge, dock construction, and other floating structures. With the strongest pneumatic rubber body, salvage rubber airbags really come into their own when airbags employed in heavy-duty salvage work under a severe environment.
1. High Buoyancy Capacity
2. Worked for Deep Water
3. Resistant to Abrasion
4. New anti-explosion design of end part
5. High kneading & compressing resistance and damping capacity
Application cases
1 Ship Launching & Upgrading
With more than 20 years development in China, Inflatable Upgrading Airbag is proved to be the most reliable and stable technique for ship launching & upgrading. It is applicable from tons of flat board to ten thousand tons of huge ship. Meanwhile, Inflatable Upgrading Airbag is also widely acknowledged by foreign dockyards, shipyards, port/harbour construction companies. Ship launching & upgrading technique with Inflatable Upgrading Airbag is also highly promoted in the markets, such as America, Europe, Southeast Asia.
2 Weight lifting & moving
Marine rubber airbag could be applied to casisson lifting, launching, moving and transporting in port constructing projects.
Buoyancy Aid & Salvage
Because inflatable upgrading airbag has buoyancy force and load-bearing capacity, it is also widely used in sunken vessel salvage and buoyancy aid.
