1. What is Yokohama Fender?
Yokohama fender, also known as floating pneumatic rubber fenders， inflatable fender, pneumatic rubber fender, yokohama pneumatic floating fender.
The middle part is cylindrical and the ends are hemispherical. It is filled with compressed air and suspended on the side of the ship or dock. When a ship is berthing with a ship or with a dock, it absorbs the impact energy and reduces the damage of the hull or dock. It is a renewal of solid fender (tied with brown rope or rubber strip) in the past.
At present, yokohama fender has been widely used in oil tankers, container ships, yachts, offshore platforms, large docks, military ports, large piers and so on.
