ISO 17357 Sling Type Yokohama Floating Pneumatic Marine Rubber Fenders Marine Rubber Fender
Description:
ISO 17357 sling type Yokohama floating pneumatic marine rubber
fenders can play an important role in a ships safe berthing
operation. Essentially there are two main types of floating
pneumatic rubber fender, defined as either high or low pressure
fenders. Although manufactured using different techniques, both
high and low pressure fenders work by the same principle. The
resistance to berthing vessel momentum is provided by a reaction
pressure due to compression of the air inside the fender when
deformed by the vessels hull. The kinetic energy of the berthing
vessel is absorbed during the work done to compress the air inside
the fender. Fenders are sized according to the expected duty of the
fender in terms of the energy absorption (EA) requirements which
will be at the most basic level, a function of the vessel mass and
velocity.
Sling type fenders are net type fenders without chains or tyre
nets, but with a specially processed outer rubber double-layered
cove r, which consist s of a single cover and an extra tyre cord
layer, resulting in better resistance to operational damages .
Main Technical Specifications:
- Standard: ISO 17357:2014,
- Initial internal pressure: 7 kPa for low pressure fender, 50 kPa & 80 kPa for high pressure fender;
- High Pressure Fender Type: Net-type; Net-type and one end with no flange opening and no metal parts; Sling-type;
