Foam Filled Fenders
Foam Filled Fenders Description
Foam Fenders are versatile, robust and suitable for almost all applications. The manufacturing process allows for virtually any size of fender to be constructed and selecting the appropriate grade of foam core and elastomeric skin means the performance of a fender can be precisely gauged to meet specific specification requirements.


 

Characteristically Foam Fenders have a high energy absorption compared to their reactive load meaning they are ideal for existing structures and certain hull types such as catamarans and cruise ships.

The Closed cell foam core used inside the fender also offers un-sinkability during operation should the integrity of the elastomeric skin be broken, should such an accident occur then the fender can also be repaired back to original performance with little effort.

Generally Foam Fenders are very low maintenance due to the tapered shape and low wear materials used in construction. To protect the body of the fender further chain and tyre nets are also available on all sizes of fender.

The versatility of Foam Fenders also means then can be installed in numerous location either free floating, moored in tidal areas or fixed out of the water directly to the quay structure.

 
Foam Filled Fenders Performance - 35kg/m3 density Foam Fenders
The performance of Foam Fenders can be modified by changing the internal density of the internal polyethylene Foam Core.

There are two standard densities we use 35 kg/m³ and 50 kg/m³.

The following table gives the relevant performance figure for the standard density 35 kg/m³ type.

Foam Filled Fenders Physical properties
As standard the fender dimensions are give as diameter x length and in millimeters.

The dimensions given are for the body only part of the fender. The weight is shown for the two standard type of fender, net less ‘Chain Through Fender’ type (CTF) and Chain and Tire Net type (CTN). Wire Netted and Rope Netted fenders are available on request.

Any other size is available on request. Please contact us with your specific needs.

Foam Filled Fenders Variations
Foam Core
The Polyethylene foams we use in the construction of our Foam Fenders is the closed cell type. These foams are flexible and resilient making them ideal for fendering products. Importantly, the foams are also chemically inert making them suitable for use in marine environments.

Our closed cell Polyethylene foams are available in a range of densities from 15 kg/m³ to 175 kg/m³.

Our two standard foam density for distinguishing the performance of our fenders are 35 kg/m³ (standard density) and 50 kg/m³ (high density) although other options are available on request.

Body Construction

Our foam fenders come in two variations of body construction. (1) Chain Through Fender (CTF) that has an internal central tensioning  member for installations that do not require an outside protective net  or require the fender to be non-marking and (2) Chain and Tire Net (CTN) fender that is protected on the outside for extra hard wearing installations.

 
CTF Fender features CTN Fender features
• Non-marking skin • Extra high protection of fender body
• Non-sparking skin • Heavy duty for roughest conditions
• Color variations for berth identification • Maximum stand-off distance
• Smooth finish and body shape • Ideally suited in tidal locations
• Suitable for hanging or fixed mounting • Suitable for towing and moving between berths
• Very low maintenance • Recommended in S.T.S. operations

 
Foam Filled Fenders Quality
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.

Our goal is therefore to meet the needs of our customers through the on time delivery of error free products, quality assurance is instrumental in the pursuit of our goal.

 Through document data and process control we can review and act, allowing to continually improve our products and processes.  Internal audits of these control procedures helps to maintain a high standard of manufacturing.

 The information obtained from the control procedures forms the basis of the Production Method Sheets (P.M.S.) systems helping us to train staff so specific manufacturing processes are adhered to and customer requirements are met.



 
 With over 10 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.


 
Foam Filled Fenders Installation
Ship to Ship applications

After selection of the correct size fender suitable for the combined energy of the two vessels (calculations can be in download area) the fenders should be equally spaced along the length of the smallest vessel.

At each end it is recommended that a smaller secondary fender is installed to protect against rolling due to swell and wind during transfer operations.

The fenders can be slung individually from mooring points along the deck or all linked together in a line fastened only at each end of the vessel. Davits can be installed along the deck to assist in mobilisation and securing of fender for use. Please see the installation diagrams below for more details.

Further detail can be found in the Transfer Guide published by the International Chamber of Shipping.

Mooring equipment will vary from project to project and can be provided for your specific need upon request.

 

Ship to Shore applications

For installation in tidal locations it is recommended that the fender is mounted to the quay at the midpoint of high and low tide, this allows the fender to rise and fall on tides with the least amount of slack in the moorings.


Alternatively the fenders can be slung from mooring points along the top of the quay including mooring rings, mooring bollards or specially installed brackets.

If the fenders are installed on a dolphin then the mooring lines can be installed along the side walls of the dolphin moving them well clear of the berthing surface.

It is important to note that the fender will significantly change shape under full compression so a sufficient flat surface clear of protrusions is required for installation. It is not recommended to install Foam Fenders onto mono-pile structures. 

Mooring equipment will vary from project to project and can be provided for your specific need upon request.
