Applications

Ship Launching & Upgrading

With over two decades of successful application in China, marine rubber airbags provide the most reliable solution for ship launching and upgrading operations. This versatile technology handles vessels ranging from small-tonnage flat-bottom boats to massive ships weighing tens of thousands of tons.

Heavy Lifting & Transportation

Marine rubber fenders serve as efficient solutions for port construction applications including caisson lifting, launching, relocation, and transportation operations. Their robust design and exceptional load-bearing capacity make them ideal for demanding marine construction projects.

Buoyancy Aid & Salvage Operations

Utilizing superior buoyancy characteristics and impressive load-bearing capacity, marine rubber airbags are essential tools for sunken vessel salvage operations and buoyancy aid applications. These airbags provide reliable performance in challenging marine environments for complex salvage missions.
