Floating pneumatic rubber fender is fender which is made of synthetic-cord-reinforced rubber sheet with compressed air inside to enable it to float on the water and work as a shock absorber between to ships, or between ships and berthing structures when they come alongside each other on the water. This high pressure floating pneumatic rubber fenders have sometimes been colloquially referred to as “Yokohama fenders” or “Yokohama type fenders”.
What is Outer Rubber?
It is rubber layer that covers the outside of the pneumatic fender to protect the cord layers and the inner liner rubber from abrasion and other external forces
What is Inner Rubber?
The liner of rubber membrane that seals the pressurized air inside the fender
What is synthetic-tyre-cord layer for reinforcement
Layer made of synthetic-tyre-cord fabric, which maintains the internal air pressure of the fender. As the main fibres of the synthetic-tyre-cord fabric are not braided like synthetic canvas fabric or synthetic belt fabric, there are advantages for its fatigue-resistanceperformance and pressure-holding performance.
Where is the bead ring?
Steel ring which is placed at one end (or both ends) of the fender and holds the end of cord layers
Where is the flange opening?
Steel flange, which is mounted on the pneumatic rubber fender, to which an air valve or safety valve can be adapted
What is guaranteed energy absorption?
It is energy that the floating pneumatic fenders can absorb without permanent deformation or failure
What is reaction force?
It is force produced by a fender reacting to a compressive force, the reactive force is equal to the force of the air pressure of the fender multiplied by the area of the fender in contact with the ship or berthing structure
What is the initial internal pressure?
It is air pressure at which can uncompressed fender operates
What is endurable pressure?
It is inner pressure at which a fender bursts
What is net-type floating pneumatic fender?
It is fender which is covered by a protection net consisting of either chain, wire or fibre and usually with tyres or rubber sleeves.
What is sling-type pneumatic rubber fender?
It is a fender which is designed to be used without a protection net
