Pneumatic Fender Type

BASIC CONSTRUCTION

The Floating-type Yokohama Pneumatic Rubber Fenders are kind of a cylindrical air bag with hemispherical heads at both ends. Basic body construction of this fender consists of an outer rubber layer, cord layers and an inner rubber layer. All of these are vulcanized together, and then proven by hydraulic pressure test.

1. Outer Rubber

The outer rubber layer protects the cord layers and inner rubber layer from abrasion and other external forces. This compound has sufficient tensile and tear strength to withstand any weather condition and hard usage as shown in Table 5-1. Standard color is black, but other colors such as grey and creamy white are available on request.

2. Synthetic-tire-cord Layer

The reinforcement cord layers, which are made of Synthetic-tire-cord, are arranged at ideal angles to hold the internal pressure and to distribute the stress evenly. As the main fibers of the synthetic-tire-cord are not braided like synthetic canvas fabric or synthetic belt fabric as shown in Fig.5-2, there are advantages for its fatigue-resistance performance and pressure-holding performance.

3. Inner Rubber

The inner rubber layer seals the air inside, utilizing a compound equivalent to that of the liner or tube of an automobile tire. The specifications are shown in Table 5-1.

GENERIC PERFORMANCE CURVE PNEUMATIC FENDERS

Safety Design and Pressure Requirements

The guaranteed energy absorption of Yokohama Pneumatic Rubber Fenders is the energy absorption at 60% deflection. This figure should be observed in engineering design and in actual operation. However, even if the fender is accidentally over-deflected beyond this guaranteed value, the Yokohama Pneumatic Rubber Fender has a wide safety margin as shown in Fig.6-4 and Table 6-5 below. These curves and table express the capacity for energy absorption and reaction force until the time of ultimate deflection when the deflection of fender reach the largest diameter of mouthpiece metal parts. This is shown by using the guaranteed energy absorption and reaction force as the index value of 1.The figures and table show the wide safety margin of our pneumatic fenders in absorbing energy and low reaction force.

Applications Cases

►In ports with extreme tidal variations

►Ship-to-ship operations

►Oil & Gas (typically FSRU)

►Temporary berthing

Shipping Method

In order to minimize the shipping cost of Yokohama Pneumatic Rubber Fenders, the fenders are usually packed and shipped in containers or on pallets in vacuumed and folded down state.
