What is Arch Rubber Fender?
Arch rubber fenders are specialized devices designed to absorb and dissipate the energy generated during the collision of vessels with dock structures, pontoons, or other marine installations. These fenders are characterized by their distinctive arch shape, which allows for a gradual deformation under load. This gradual deformation enhances the fender's ability to absorb energy over a wider range compared to flat or cylindrical fenders, making them particularly effective in handling heavy impacts and dynamic loads.
Mountains Super High Reaction Force Super Cell Rubber Fenders for dock with PE Front Panels are mostly installed for docks (Dock medium type to VLCC) where reaction force is an important criteria.

700H Super Cone Fender System For Wharf Dock
The rubber cone fenders as rubber bumper guard are manufactured from a high-quality rubber compound, and have been specifically designed for use in marine berthing applications. They combine excellent energy absorption with low reaction force upon contact in order to berth vessels of all sizes.
● When the design compression deformation is large (without increasing the reaction force), the rubber gasket is 20% higher than V-type and 8% higher than M-type, which greatly increases the energy absorption of products.
● In the compression fender series, arch fender (TD-B) has high energy absorption per unit weight (rubber consumption).
● It has good anchorage and is suitable for ships, wharfs, docks and so on. It has a wide range of applications. Zy16.
● The disadvantage is that the pressure acting on the ship's side slab is high, so it is not suitable for ships (such as oil tankers) with lower strength of the ship's side slab. Fifth, the front of TD-BB fender (working face) is equipped with anti-impact board and PE panel, which can reduce the surface pressure and friction coefficient with the ship plate, thus greatly reducing the mooring shear force. A kind of.
● When the ship's side plate is uneven (small boat or protrusion), it often causes the deformation and damage of the impact plate of TD-BB fender in berthing. The TD-BPE fender is designed to meet this need, so as to reduce the friction coefficient and the shear force of berthing.
What Are Arch Rubber Fender Used For?
Ports And Harbors
Dock fenders are usually installed along the quay walls and docks. They shield vessels during docking and mooring operations. Dock fenders are crucial safeguards and prevent damage to water vehicles and the port. They ensure efficient maritime operations.
Shipping Industry
Boat and dock fenders are prevalent for manufacturing ships and vessels of all sizes. These rubber fenders on the boat protect the hull from collisions with other water vehicles. It also protects the hull from locks or piers.
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.
What Are Commonly Used Types Of Rubber Fenders
Solid Rubber Fenders
Because of its durability, robustness, and resistance to wear and tear, solid rubber fenders are commonly utilised. They are appropriate for a wide range of nautical applications, including berthing and mooring.
Pneumatic Rubber Fenders
Pneumatic rubber fenders are widely utilized in the offshore industry because they can absorb a large amount of energy and are extremely effective at protecting vessels and offshore buildings from accidents.
Cone Rubber Fenders
Cone rubber fenders are frequently employed in high-energy applications such as offshore platform protection or as a buffer for a ship's bow
Foam Rubber Fenders
Because they are lightweight and absorb stress well, foam rubber fenders are typically utilized in smaller applications such as recreational boats.
Ships will inevitably collide with the pier when they are berthing or unberthing,because the impact force of the ship is very large,so that the pier and the ship face potential damage hazards;in addition,when the ship is docked at the pier,it is in strong wind,Under the action of waves and currents,the ship forms complex mechanical effects on the wharf,such as volume pressure,impact,and kneading,thereby causing potential damage to the ship and wharf.Therefore,it is necessary to install marine rubber fenders,and at the same time install suitable dock fenders for the dock to absorb the kinetic energy of the ship and reduce the force between the ship and the dock.
The pier rubber fender is an effective pier anti-scourage facility.The key fenders currently used in container port terminals include four types:drum,drum,D and arch.The selection of rubber dock fenders is confirmed according to the characteristics of the dock and the ship.The factors that need to be considered include the horizontal bearing capacity and energy absorption of the dock,as well as the shape,draft,curvature and surface pressure of the ship.Drum and drum fenders are used to bear the first impact when the ship is berthing.Because the impact is relatively large,it is stipulated that the wharf fenders have relatively large energy absorption and strong reaction force characteristics;D-type and arched fenders As a Class 2 fender,the impact is not large.Therefore,the D-shaped and arch-shaped fenders of large piers should be used in conjunction with drum and drum pier fenders.In addition,D-shaped and arched fenders have unique advantages in terms of edge protection and shear resistance of the pier.
The characteristics of energy absorption and reaction force are the key index valuesto consider the quality of the rubber fender.In an ideal situation,about 70%of the kinetic energy of the hull can be absorbed by the fender.To protect the firmness of the wharf and the safety factor of the ship,the impact force of the ship on the wharf should be less than a certain standard.Under the buffering effect of the fender,the impact force of the ship on the wharf is weakened,so that the wharf and the ship will not be damaged.Therefore,the rubber fender should maintain a certain amount of reaction force after being compressed by impact.The reaction force and energy absorption curve of cylindrical fender and drum fender under vertical compression.
Factors for Choosing the Right Type of Arch 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.
● Pass plastic woven bags, cloth bags, or hemp rope through the mounting holes on the arch fender, and tighten the fender for lifting, not allowed to use wire rope or other hard metal chains for lifting.
● Lift the arch fender towards the accurate location where the anchors are on the dock.
● Corresponding to the embedded location in the dock, insert the washer into the mounting hole and tighten it with the bolt.
● Tighten all bolts.
● Clean up the installation traces, and smudge that may appear in the process, and finally complete the arch fenders assembly installation.
Check the foot bolts for fender buffer installation and the bolts for fastening the front panel and fasten them enough. In case of any loose and then fix the fastening bolts and panel by spot welding.
Check the fender buffer for any break or cut. Please contact our company immediately for the heavy cutting.
Check the front panel for any dent, crack or corrosion. If does, please contact our company. Annual anti-corrosion treatment is to be carried out to the front panel in avoid of rusting.
Check the front panel for any inclination. The material accumulating in the inner part of front panel will easily cause frontal in clination, so the accumulator in the inner part of the front panel shall be cleaned as much as possible.
Check the front panels for any scratching or compression damage replace the spoiled one as soon as possible.
Check the concrete structure area where the fender system installed for any crack appearance , if exists ,contact relevant department immediately for treatment.
Check the rubber elastic parts for suspending the front panel to ensure them under proper condition, replace and unpractical one.
Installation Steps For Arch Rubber Fender
● Both ends of the Arch Rubber Fender should have sealing plates and beveled. The rubber fenders will gradually transition to disappear naturally. The height-to-width ratio of the beveled ends should be greater than 3:1. Then the doubler plate should be partially relaxed and strengthened at the end.
● The end point of the Arch Rubber Fender should fall on the internal structural rib of the hull, such as ribs, rubber fender ribs.
● The seams of the hull shell, the doubler plates of the fenders, and the butt joints of the rubber fenders and fenders themselves should be staggered by at least 10cm.
● With the active development of pre-installation projects, fenders are often pre-installed on sections. Rubber fenders Therefore, the fenders should leave a section of 1-1.2m outside the large joints of the sections to be bulked on the slipway. Once the tightness of the large joints in this section is accepted, the fender can be installed in this section.
● The horizontal and vertical ribs in the fenders are generally not welded with the outer plate of the hull, and a gap of 10mm should be left on the rubber fenders.
