Yokohama Type Black Ship Marine Pneumatic Natural Rubber Fender With Chain Tyre Net
Pneumatic rubber fenders manufactured based marne pneumatic rubber fender standard iso 17357-high pressure. Yokohama floating pneumatic rubber fenders are filled with air in cylindrical body used for a inflatable bumper for boats, navy ships vessels and marine barges STS ship to ship transfers, STB ship to dock berthing. Since floating yokohama pneumatic marine rubber fenders is made of rubber, oil & water resistance, are widely applied to gas energy, marine field. Pneumatic rubber fenders can be deflected to 60%, showing a stable performance among the marine fenders systems.
Pneumatic Fenders Classification
According to pneumatic rubber fenders international standard, floating pneumatic rubber fenders system are grouped into two. And from appearance, fenders for ships and marine are classified another two:
In accordance with requirements of ISO 17357-1 high pressure yokohama type floating pneumatic rubber fenders, marine pneumatic rubber fenders performed at pressure of 50 Kpa and 80 Kpa only, which are listed in below sheet demonstrates sizes of pneumatic rubber fenders from diameter 0.5 m ~4.5 m , 1.0 m ~12.0 m in length, we are now available to supply below sizes of pneumatic rubber fenders.
Initial Pressure 50 Kpa, P50 pneumatic fender
Initial Pressure 80 Kpa, P80 pneumatic fender
Pneumatic Rubber Fenders Construction
– High tear strength inner rubber layers
– rubber dipped synthetic tire cord reinforced layers
– Durable outer rubber layers, end accessories and fittings
Marine Fenders Feature
Features set forth performance of pneumatic rubber fenders while under actual applications including follows:
When ship berth to a dock or another ship for sts transfer, their first contact is usually at an oblique angle. In this case, pneumatic rubber fenders perform different. For solid rubber fenders, their energy absorption, reaction force will decrease considerably at this inclined compression comparing with parallel compression, thus, a larger size of solid marine rubber fender would be selected for instead. But for pneumatic rubber fenders, due its cylindrical body structure, freedom of air and flexibility of rubber layers, floating yokohama pneumatic rubber fenders can distribute the load along the hull of a ship or vessel structure under inclined compression,deflected to 15 degree.
Application & Installation
Pneumatic rubber fenders generally have two main applications for ships: ship to ship transfer and ship to quay operation.
Ship to ship: normally, for lighter weight ships transferring work, smaller pneumatic rubber fenders are enough. But for heavy duty barges or vessels, bigger-sized pneumatic rubber marine fenders with more quantity are necessary. The pneumatic rubber fenders are hung alongside of ships hull with mooring chains or fibre ropes.
Ship to quay: pneumatic rubber fenders are installed side of ports to absorb berthing energy when ships docks. Fenders are hung also by guy chains or ropes, same as ship to ship operation.
Pressure Requirements
Referred to pressure of one pneumatic rubber fender for marine, there are initial pressure without deflection of one pneumatic rubber fender and pneumatic fenders at 60% deflection, hull pressure at related deflection, and safety valve pressurings as well as tested pressure of a pneumatic rubber fenders
