Rubber fenders provide a cushioning effect that aids in the protection of employees in the case of an accident or impact.

Durability

Rubber fenders are extremely robust and resistant to harsh marine environments, making them an excellent choice for vessel protection.

Cost-effective

Marine rubber fenders are a low-cost option for vessel protection since they require less maintenance and are less prone to damage than other types of fenders.

Versatility

Rubber fenders are available in a number of shapes and sizes, allowing them to be used in a wide range of applications and situations.

What are the Applications of Marine Rubber Fender

Marine Terminals

Marine rubber fenders are essential at marine terminals. They shield loading and unloading equipment like cranes and cargo handling machinery. Marine rubber fenders ensure a secure and smooth transfer of goods.

Trucks And Lorries

Beyond maritime applications, rubber fenders can also be seen in the automotive industry. Trucks and lorries use rubber fenders to protect themselves from collisions and impacts. These rubber products safeguard both the vehicle and nearby structures.

Building Interiors

Rubber fenders are integrated into the building interior to cushion impacts. These rubber products are used in high-traffic areas like parking garages and warehouses. They help prevent damage to walls, columns, and vehicles in indoor environments.

Recreational Boating

Boat dock fenders are prevalent in recreational boating manufacturing. These rubber products are used on boats and yachts to prevent hull damage during docking and mooring. These fenders ensure the longevity of vessels while maintaining aesthetics and functionality.

Types of Marine Rubber Fender

Pneumatic Rubber Fender

When it comes to getting the best and the leading anti-collision device for the marine application, one name always remains at the top, pneumatic rubber fender. These fenders play a very crucial role in different marine applications. They also act as the protective medium against the collision in ship-to-ship contacts and so in the other depending applications as well. These kinds of rubber fenders in the UAE can be a lot helpful not only when the ship is on the dock but also on the voyage.

Hydro Pneumatic Rubber Fenders

Hydro-pneumatic rubber fender is a high-performance anti-collision device mainly used to protect ships docked at docks. Compared with traditional dock fenders, semi-submersible fenders exhibit better performance and features. It adopts a unique design concept to provide more precise protection for boats of different sizes and shapes, thereby effectively reducing the risk of collision and damage.

Physical Properties of Marine Rubber Fenders

01.

Elasticity

Rubber fenders are highly elastic. In this case, they allow them to deform and absorb impact energy during collisions. Then, it returns to its original shape.

02.

Tensile Strength

A rubber fender usually provides excellent tensile strength. It means that they can withstand large stretching forces without breaking.

03.

Resistance

A rubber fender is also resistant to various environmental factors. For example, abrasion, weather, chemicals, and temperature are noteworthy.

04.

Compression Set Resistance

A rubber fender has good resistance to compression set. It can maintain its shape and performance even after prolonged squeezes. It also ensures the durability of the product.

How Does A Marine Rubber Fender Work?

A rubber fender works on the principle of elasticity and molecular deformation. The process absorbs and dissipates kinetic energy during collision or contact with structures.

We know that Fender rubber seals are synthetic rubber compounds. It is composed of long polymer chains. These polymer chains are highly flexible and famous for elasticity. When a collision occurs, it exerts a certain amount of pressure on the rubber surface. The polymer chains then start to stretch and deform. Note that when a force is applied through polymer chains, it causes them to align in the direction of the applied force. As the chains stretch, they absorb and store the energy from the collision as potential energy.

Once the external force is removed, the polymer chains naturally return to their relaxed state. At this moment, they release the stored potential energy gradually. This absorbed energy is converted into heat and released through different mediums. This releasing energy mechanism acts as a cushioning method. It reduces the impact force transmitted to the vessel or structure.

Rubber fenders utilize this technique to absorb and gradually release the energy from collisions. This elasticity and molecular level deformation prevents damage to vessels and structures.

How to Choose Marine Rubber Fender

Vessel dimensions
Vessel dimensions, in terms of type and dead weight tonnage, become significant factors in choosing not only the right fender type, but also the size of the fender. The larger the vessel, the larger the required fenders will be. Usually, fenders which are equipped by frontal frames are chosen as they have large contact area.

Type of the port
Another significant factor that can influence in choosing the right type of fender is the type of the port. Based on the location and position of the port, there are several port structures that are usually used including dolphin, monopile, jetty and quay wall. In the dolphin terminal, the terminal consists of poles that are used for vessels to berth. Rubber fender that is usually used in this terminal is super cell fender. However, jetty terminal, which is also known as floating terminal, does not need a really tough construction as it floats. This terminal is used for passenger ships. Unlike other kinds of ports, terminals with quay wall consist of concrete structure which parallels the beach. Large vessels cannot berth on this terminal due to the shallow waters in which the terminals are usually located.

Marine environment
The marine environment, such as high and low tides of the seawater, the power of wind which influences the waves, is another factor that needs to be considered in choosing the right fender type and dimension. If there is a big difference between the high and low tides, elongated fenders must be chosen, especially when the port is used by diversely sized vessels. If a small vessel needs to berth during the low tide, it can still berth to this port. Therefore, it is recommended to have the fenders installed in vertical position. On the other hand, when the sea is windy and wavy, the water also gets rough. This causes vessels to bump into the port wall. Elongated V type fender (leg fender), super cell or cone fender equipped by frontal frames can be used for this type of port.

The availability of guidance during berthing process
The availability of tugboats during berthing process is very important in order to avoid vessels from crashing into the port wall. This is because the speed of the vessel and the berthing angle can be adjusted as the vessel moves closer to the port.

How To Place Rubber Fender In Proper Position?

The spacing and elevation of marine rubber fenders are very important. It is necessary to ensure that the ship can not directly touch the quay wall under the most unlucky berthing sight point allowed by the standard. It is also necessary to ensure that the ship can safely berth at different tide levels and draughts, and has strong adaptability to ships of different tonnage. Fender is an energy-absorbing device for ship berthing stability. Due to the effect of wind, wave, and current, as well as the difference between wharf azimuth, and the influence of high and long period wavelet waves on the harbor basin, a large amount of energy can occur when a ship collides with a dolphin, which requires that the fender has a good energy absorption characteristics.

How to Maintain Marine Rubber Fender

Regular Inspection

Regularly inspect the fenders for signs of wear and tear such as cracks, punctures, or deformations every six months. Examine the chain and shackles that connect the fenders to the vessel or structure for signs of wear and tear.

Cleaning

Cleaning the fenders on a regular basis will help to eliminate dirt, grime, and other debris that may have accumulated on the surface. To avoid harming the rubber, use a light soap or detergent and a gentle brush or cloth.

Lubrication

Lubricate the chain and shackles with an appropriate lubricant to prevent corrosion and maintain good operation.

Storage

When not in use, keep the fenders in a cold, dry area. Keep them away from bright sunshine and harsh temperatures, which can degrade the rubber.

Testing

Test the fenders on a regular basis to ensure that they can still absorb the needed amount of energy. This can be accomplished by impact testing or by measuring fender compression.

Repair or Replacement

Repair or replace the fender if damage is discovered. Damaged fenders should not be used because they may not provide appropriate protection and may fail after a collision.
