High Gas Tightness Submarine Fenders Rubber Material For Ship Docking

1.SGS Passed High Gas Tightness Submarine Rubber Fenders For Ship Docking 

"Yokohama Pneumatic Inflatable Rubber Fender " progress in the development of such floating pneumatic rubber fenders is closely related to the progress and development of ship technology, and has to continuously cope with progressively larger oil tankers such as VLCC's, ULCC's, large gas carriers, bulk carriers and floating structures.

Floating pneumatic fenders are used world wide for
ship-to-ship (STS) transfer operations, terminals, and for all kinds of ships.

5.1  Safety and Reliability

Yokohama Pneumatic Rubber Fenders are constructed of several layers of strong
tire-cord, and are thus resistant to pressure and cutting. The safety factor adopted in the
design of this fender is based on accepted theory and has been proven by extensive
experimentation. Operational experience over a long period of time attests to its high
safety and reliability, and hydraulic pressure tests have proven the strength to be suitable.

5.2 No Deterioration or Variation in Performance

Yokohama Pneumatic Rubber Fenders utilize the compressive elasticity of air, therefore
performance deterioration due to fatigue is absent.
In the case of solid rubber fenders or foam-filled fenders, based on data were taken
from comparison tests of Yokohama Fenders, there are variations in performance. Such
performance variations are associated to changes of rubber or foam hardness occurring
as a result of cyclic compression and temperature change.

The good performance of the Yokohama Pneumatic Rubber Fenders remains unchanged
even at temperatures under -50 degrees Centigrade (-58 degrees Fahrenheit).

5.3 Advantages at Inclined Berthing

Ships usually make initial contact with the dock or another ship on STS operations at an
oblique angle.

In the case of Yokohama Pneumatic Rubber Fenders, energy absorption does not
decrease at inclined compression up to 15 degrees.

5.4 Most Cost Competitive System

The utilization of the compressive elasticity of air, unlike other fenders which need protector panels, provides completely uniform surface pressure on contact. The surface pressure is equal to the internal air pressure

5.5 Stronger against Shearing Force

After contacting a dock, a ship is usually shifted to the correct mooring position. The
shifting exerts shearing and compression forces on the fenders. This combined force is
very severe in the case of solid rubber fenders because they are not reinforced against
such force. In contrast, Yokohama Pneumatic Rubber Fenders are adequately
reinforced using strong tire-cord to cope against such forces as well as internal
pressure.

5.6 Simple and Low Cost Installation

The weight of Yokohama Pneumatic Rubber Fenders is supported by the water on which it floats.
Therefore, the fender can be moored simply by means of a guy rope or chain, requiring minimal extra
cost. It can be removed easily to a suitable jetty or quay when not in use, or transferred to another
mooring point whenever required.

5.7 Low Maintenance Cost

Maintenance cost is very low. Although the internal pressure will vary with seasonal changes, the air leakage is so minimal that it is sufficient to check the air pressure only once a year. The chain net needs to be replaced only once in 3 or 4 years, depending on ambient conditions.

5.8 Shipping Cost Minimization

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.

7.Yokohama Pneumatic Inflatable Rubber Fender Installation Methods

At both ends of the fender, first shackles, then swivel joints, followed by a further shackle
should be installed. A guy chain or guy rope is secured to the outer shackle. The swivel
joint prevents twisting of the guy chain or wire.
