Hawk Airbag Factory was founded in 1999. In 2002, Hawk developed a new product — Pneumatic Rubber Fender (PNE) and has obtained the New Type PNE invention patent in 2004. In 2006, Hawk Airbag Factory was renamed as Hawk Floating Fender Company. Since 2002 until today, more than 6,200 Pneumatic Rubber Fenders and more than 21,000 Foam Fenders have been supplied worldwide both for ship-to-ship and ship-to-dock operations serving our valuable customers. These fenders play a critical role in the safe operation of ship berthing and mooring. Hawk Fender confirms that all its Pneumatic Rubber Fenders fully comply with all requirements of ISO 17357. We design with harshest conditions and your toughest challenges at the forefront, manufacturing end-to-end in our own production facility. This ensures the best quality and performance available.

Pneumatic Rubber Fenders are ideal for mooring, ship-to-ship transfers, offshore platforms and floating docks requiring minimal maintenance, so costs are kept down. Hawk Fenders have the merits of high-pressure resistance, high energy absorption low reaction, ageing resistance and saltwater corrosion resistance.  They support berthing at angles up to 15 degrees for advanced vessel types such as ULCC, FLNG, FSRU, FSU, FSO, FPSO, LNG and bulk carriers. Fast and easy to deploy, Hawk Fenders ensure clearance is maintained between the hull and jetty or other vessels. Risks of damage during mooring is minimised, protecting both people and vessel. Due to the hollow construction, these fenders are lighter and easier to handle than solid rubber models. 

Product Type

There are two basic types of 
PNE that comply with ISO 17357: Tyre - Chain - Net Type and Sling Type, based on these two type. Hawk Fender also have Hawk S-series Fender which contains Barrier Cover and Hawk Mark-less Series Fender.

Pneumatic Rubber Fender Construction

Outer Rubber 

 

The strong abrasion resistance outer rubber is designed to protect the inner rubber and cord fabric layers from damaging external forces. The material has mechanical characterises to withstand the surround operational conditions for which it is designed. The diagram below shows the actual properties as specified in ISO 17357-1:2014. Generally, the natural colour of outer rubber is black, it sometimes can bring black marks to the vessel, therefore to avoid black marks, other colours such as grey, off-white, green, orange and red etc. can also be supplied upon request. 

 

Tyre-cord Layer

 

Synthetic cord fabric layers have proven to be the best option for strong, efficient reinforcement for pneumatic rubber fenders. Each layer is coated with a rubber compound on both sides that prevents contact between the layers, reducing friction and wear during bending, compression and stretching. The same compound isolates each thread within the layer. It can improved the ability of the fender to hold pressure, fatigue resistance and endurance life. A schematic of the construction is shown below. 

 

Inner Rubber 

 

The inner rubber seals pressurised air inside the fender. It is usually constructed of a compound similar to that of an inner tube in a truck or car tyre to ensure a good level of air tightness.
