2.5x4m Marine Inflatable Fender , Berthing Inflatable Dock Bumpers

ISO 17357 Marine Inflatable Rubber Fender Marine Boat Fender with certificate

Product Overview

The following factors should be considered in the selection of pneumatic fenders:

(1) Maximum energy absorption E; (2) Reaction force; (3) Distance
requirements after berthing of two ships or the berthing distance
from the ship to the dock, including the maximum distance and the
minimum distance; (4) The size of the ship; (5) Factors such as
wind waves and temperature changes in the actual use environment.

The selection of pneumatic fender system first needs to determine the collision energy of the ship when
berthing and after berthing, and select the specifications of
pneumatic fender according to the distance requirements (maximum
distance and minimum distance) after berthing, and verify whether
the maximum reaction force of pneumatic fender is within the
allowable range of hull design.
If it is necessary to improve the energy absorption of the
pneumatic fender, increasing its diameter is an ideal choice. The
number and spacing of pneumatic fenders are determined according to
the size and actual use of the ship.
Yokohama pneumatic marine rubber fender can be delivered in various
sizes and types. Chain and tyre net (CTN) type is usually
recommended to protect the fender body, but sling type or body only
is also available.
1.Outer Rubber
Cover outside on the ball of rubber layer, which is used to protect
skeleton material and inner rubber ball from damage of external
force.
2.Cord layers
Reinforced cord rubber layer is composed of winding synthetic cord
layer, it is mainly used for maintain the internal air pressure.
3. Inner Rubber
On the ball inside the rubber layer, which is used to prevent air
leakage and control the ball pressure.
4. End Flange
The metal parts at both ends of fender, which can be fitted with
charging valve and safety valve.

PNEUMATIC MARINE RUBBER FENDERPneumatic Rubber Fenders have been in use for around 50 years. It
is the leading anti-collision device for marine application in the
world. This compressed air filled rubber fender is used as a
protective medium for ship-to-ship contact (STS), ship to quay
(STQ) and ship-to-berthing (STB).
FEATURES
• Easy and fast to deploy
• Very low reaction and hull pressure
• Performance adjustable by varying initial pressure
• Suitable for areas with large or small tides
• Maintains large clearances between hull and structure
• Optional chain-tyre nets for heavy duty applications
• Tankers, Gas Carriers and Bulk Cargo Ships
• Fast ferries and aluminum hulled vessels
• Temporary or permanent installations
• Rapid response and emergency fendering
• As stand-off fenders to realign ships with shore facilities

-Note:The tolerance of reverse force and energy absorbed is +/-10%.

-Other dimension can be customized according to requirements.

Structure

---Material

Synthetic-tyre-cord layers commonly used in tyres, have been proved to provide strong efficient reinforcement layers in fenders. Each layer is coated with rubber compound on both sides as well as in between synthetic-tyre-cord threads, hence isolating all cords from each other.

1. Wrap threads that run vertically through the synthetic -tyre-cord pattern.

2. Weft threads that run perpendicular to the wrap threads.
