Pneumatic Rubber fenders have been in use for around 50 years. The development of the Pneumatic Fender has progressed through the years in conjunction with the changing shapes, designs and size of ships and ship technology. These days Pneumatic Fenders are widely used in the off-shore transfer of oil and other chemicals. For gas, bulk, car and passenger carriers and on many installations of floating structures, pontoon and off-shore platforms.
Pneumatic Fenders are constructed of three vulcanized layers each providing an important function in the construction and lifespan of the fender. The three layers are (1) the inner rubber layer (2) the cord layers of reinforcement and (3) the outer rubber layer.
The outer rubber layer has a special compound that provides extra tensile and tear strength to protect the fender from harsh weather conditions and heavy usage whilst the inner rubber layer is specifically designed to seal the air inside and to prevent any leakage much like the inner tube of a tire. The reinforcement layer has cross hatched synthetic tire cord designed to evenly distribute the stress.
By sandwiching the reinforcing cord layer between the inner and outer rubber layers it is protected from abrasion and degradation from outside forces. The reinforcement is specifically designed to be pressure holding and fatigue resistant.
We understand how important it is to design, manufacture and supply high quality and reliable fenders that can be put into service in the harshest environments with confidence.
This is why all our fenders manufactured since 2002 have been accredited and certified to the international standard ISO17357. This is not a standard that you have to ask for with us, this is something we supply as standard across our range to ensure quality in materials and reliability in service.
We employ a strict in-house quality assurance program backed up with a detailed report available to all customers along with a third party inspection of our manufacturing processes, material sourcing and finished product testing.
With over 20 years experience in the supply of Pneumatic Fenders for Ship-to-ship use and for ship-to-shore use it is important to us that we supply high quality products that will perform as required to back up our reputation as a leading supplier of high quality fenders.
Lower quality materials and cheaper products that are not manufactured to the highest standards can often fail at critical moments such as during the transfer of crude oil in exposed location; such an accident can lead to environmental damage as well as expensive and timely repairs or worst still health and safety considerations for personnel working in the environment.
This is why we take quality so seriously and why every single fender fully complies with the requirements of ISO17357
CTN Type
Pneumatic Fenders are usually supplied with a protective Chain & Tyre Net (CTN) fitted around the body giving extra protection to the body of the fender. The CTN is constructed of galvanised chain and shackles covered at the joins with used truck tyres (or aircraft tyres on request) and along the length of the chain with rubber tubes. Anti-scratch matting can also be supplied inside the tyre centres for added protection if required. On smaller diameter fenders a chain net or rope net can also be supplied.
Hydro-Pneumatic (Submarine Fender)
Our range of Hydro-pneumatic fenders are designed to be installed vertically making them ideal for use with submarines or vessels whose impact point is likely to be below the waterline such as Catamarans, Semi-Submersible platforms and Drilling Rigs.
The fenders are manufactured with a water tight bladder inside that has external access points for ballasting and trimming.
The bottom end of the fender is fitted with an additional ballast weight to prevent the fender from flipping.
The fenders can be installed on most Quay structures and come in a range of sizes to suit the application and a range of vessels.
Sling Type
Pneumatic Fenders that are supplied without a factory fitted CTN are referred to as a sling type, this fender has modified end fittings allowing the fender to be lifted and installed efficiently.
RIB Type
If a low-maintenance options is desired the fender body can be manufactured with reinforced rubber ribs crossing the body in a grid format. This provides extra protection for the fender body but does not suffer the wear and tear of conventional CTN protection.
Fender Body Colour
Various colour’s can be achieved on the outer layer of the fender providing for berth identification or corporate branding. As standard the fenders are supplied in Black but the can be offered in Orange, Red, Grey, Cream or other colours upon request.
