Pneumatic Fenders
Inflatable Marine fenders are commonly used for ship-to-ship transfer fenders and are also used for ship-to-moor operations in shipyards/docks. It was previously invented by the manufacturer of YOKOHAMA, so it is now also called Yokohama Marine fender or Marine anchorage ball.
Marine ball after years of improvement, the use of special production technology and high-performance materials, so that it has better energy absorption characteristics. Marine ball installation is convenient, foldable delivery, for buyers to save 2/3 of the transportation cost, is a better choice to protect large ships.

PRODUCT DETAILS

Inflatable fenders range in diameter from 300 mm to 4,500 mm. Lengths range from 500 mm to 12,000 mm, as well as special sizes. Suspension or sheath models are available in two sizes. Inflatable fenders are available in standard sizes, while we can customize any size of inflatable fender to meet user requirements. The colors are usually black and gray (navy blue), and if you need more, we are willing to provide custom service.
