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 .
