1. Pneumatic Rubber Fender Features
"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.
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.
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).
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.
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 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.
