Details from ISO 17357
3.1 floating pneumatic rubber fender
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 two ships, or between ships and berthing structures when they come alongside each other on the water
NOTE The fenders have sometimes been colloquially referred to as okohama fenders or Yokohama type fenders. These are examples of suitable products available commercially. This information is given for the convenience of users of this International Standard and does not constitute an endorsement by ISO of these products.
3.2outer rubber
rubber layer that covers the outside of the fender to protect the cord layers and the inner liner rubber from abrasion and other external forces
3.3inner rubber
liner of a rubber membrane that seals the pressurized air inside the fender
3.4synthetic-tyre-cord layer for reinforcement
layer made of synthetic-tyre-cord fabric, which maintains the internal air pressure of the fender
NOTE 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-resistance performance and pressure-holding performance. See annex A.
3.5bead ring
steel ring which is placed at one end (or both ends) of the fender and holds the end of cord layers
3.6flange opening
steel flange, which is mounted on the fender, to which an air valve or safety valve can be adapted
3.7guaranteed energy absorption
energy that the fender can absorb without permanent deformation or failure
3.8reaction force
force produced by a fender reacting to a compressive force
NOTE 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.
3.9initial internal pressure
air pressure at which an uncompressed fender operates
3.10endurable pressure
inner pressure at which a fender bursts
3.11net-type fender
fender which is covered by a protection net consisting of either chain, wire or fibre and usually with tyres or rubber sleeves
3.12sling-type fender
fender which is designed to be used without a protection net
