marine rubber fenders For Ship Vessel

Chain Net Yokohama Fender , Ship To Boat Fender Rubber With Tyres

 

Floating yokohama fender is a 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 the absorber between ship to ship , ship to berthing structure when they come alongside each other on the water . The design and selection of floating fenders can be confirmed as per the maximum energy absorption of specific conditions .we should calculate and compare the requirements for the energy of the following condition; The Kinetic energy when the ship berthing or after berthing; the energy of relative motion of ship to ship and ship to wharf .

Fender structure

Outer Rubber

The tough abrasion resistant outer rubber is designed to protect the inner rubber and tyre-cord layers from damaging external forces. The material has mechanical properties to withstand the arduous operational conditions for which it is designed.

The diagram below shows the actual properties as specified in ISO 17357. Generally, the outer rubber is black, but other colours such as grey and off-white can be supplied upon request.

Tyre-cord Layer

Synthetic tyre-cord layers have proven to be the best option for strong, efficient reinforcement for pneumatic rubber fenders. Each layer is coated with a rubber compound on both sides that prevents contact between the layers, reducing friction and
wear during bending, compression and stretching. The same compound isolates each thread within the layer.
This greatly improves the ability of the fender to hold pressure, fatigue resistance and endurance life. Other reinforcing layer materials such as canvas have wear points that significantly reduce the life off the fender. 

Inner Rubber

The inner rubber seals pressurised air inside the fender. It is usually constructed of a compound similar to that of an inner tube in a truck or car tyre to ensure a good level of air tightness.

OCIMF Table Selection of YOKOHAMA fenders

It is a quick reference selection based on 50 Kpa ( Pneumatic 50 ) and calm condition , Equivalent Displacement coefficient (C) should be calculated firstly , then make the tentatively selection as per OCIMF ship to ship transfer guide .

C= 2 x Displacement ShipA x Displacement ShipB / ( Displacement ShipA + Displacement ShipB )

Berthing Energy Calculation of pneumatic rubber fenders

The berthing energy can be calculated by the following formula .

floating fenders

Where :

E = Berthing Energy ( in KNm or ton / m)

marine rubber fenders = Equivalent Displacement Coefficient

rubber narine fenders = Relative Approaching Velocity

ship fenders = Eccentricity Factor

SF = Safety Factor

Where :

ship rubber fenders = Water displacement of the berthing ship A ( tons )

rubber ship fenders = Water displacement of the berthing ship B ( tons )

rubber marine fenders = Added mass coefficient of ship A

rubber pneumatic fenders = Added mass coefficient of ship B

Added Mass Coefficient

marine fenders or

rubber fenders

Where :

d = Full load draft (m , ft )

B = Molded Breadth (m , ft )

floating rubber fenders = Block coefficient

Safety Factor

A safety factor (SF) value from 1.0 to 2.0 for the berthing energy shall be considered for abnormal berthing conditions .

Where :

I = Radius of rotation of the vessel ( usually 1/4 of the vessel’s length )

r = Distance of the line paralleled to wharf measured from the vessel’s center of gravity to the point of contact

a = the angle degree

floating rubber fenders = Block coefficient

L = Length of ship
