Marine Boat Fender

A boat fender is a type of fender specifically designed for marine applications to protect ship and berthing structures from collisions during docking or mooring operations. It is made of high-quality rubber or elastomeric materials that have excellent impact resistance and durability.

Marine Rubber Fender

Marine rubber fenders are typically installed on the sides of ships, docks, piers, or other marine structures. They act as a buffer or cushion, absorbing the kinetic energy generated when a vessel comes into contact with the ship fender. This helps to reduce the impact force and prevent damage to both the vessel and the docking structure.

Dock Boat Bumpers

Dock bumpers and marine fenders are similar products, but they serve slightly different purposes.

Dock bumpers are typically installed on docks, piers, or wharfs to protect the structure from damage caused by vessel impacts. They act as a cushion between the vessel and the dock, absorbing the energy generated during berthing or mooring. Dock bumpers are usually made of durable materials such as rubber, foam, or plastic, and they come in various shapes and sizes to accommodate different docking scenarios.

Gosea Marine's Ship Fender for Sale

Our company specializes in providing various types of high-quality marine fenders such as rubber inflatable airbags, inflatable rubber fenders, solid polyurethane floating fenders, marine airbag and yacht fenders. Our products are widely used in large docking yards, offshore platforms, ports and terminals, ships’ launching, stranded rescue, and large object handling. We can provide Classification society certificates such as CCS, LR, DNV, BV, ABS, NK, KR, and so on.

Pneumatic Rubber Fender

Pneumatic rubber fenders use compressed air as a buffer medium to absorb the impact energy of vessels. Compared to traditional compression fenders, they have the following advantages: high energy absorption, low reaction force, large contact area with the vessel, low unit surface pressure on the vessel, no performance degradation under tilted compression, and easy installation. They can be applied for mooring in all directions and are widely used in offshore mooring.

The pneumatic rubber fenders developed by our company use a new winding technology, which has the following features compared to traditional manufacturing methods:

  • Large energy absorption and small reaction force.
  • Good resilience, no deformation under load, and low unit surface pressure on the vessel.
  • Easy installation and low maintenance cost.
  • Self-floating, not affected by tidal differences.
  • Lightweight and cost-effective.
  • No performance degradation under tilted compression.
  • Pneumatic rubber fender Size : D1.0 m × L1.54 ~ D3.3m × L6.5m
  • Structure: Outer rubber, Synthetic cord reinforced rubber layer, Inner rubber, Flange opening.

Our Pneumatic rubber fenders are produced in strict accordance with the ISO17357-2002 and GB/T 2002-2002 international quality standard.

Pneumatic fenders with tire net

Bind several rubber tires to the sphere by anchor chains with both ends tying to special mooring rings,it is flexible to turning around and suitable for large ship fenders. 

Our sheathed pneumatic rubber fenders (mooring buoys) are developed and produced based on ISO17357 Net Type Pneumatic Fenders. Their outstanding feature is that the fender body is wrapped with a tire chain net, which extends the service life of the fender. The tires we use have been specially treated for a more aesthetically pleasing surface, and the chains are hot-dip galvanized for better resistance to seawater corrosion.

The Advantages of Our Marine Fender Systems

Our marine fender has several advantages, such as long-lasting wear resistance, high strength, no deformation, and simple installation. Here are some specific advantages of our products:

  1. The content of pure natural rubber in our products is guaranteed to be above 54%, which ensures durability and long service life.
  2. The internal braided wires of our products are made of nylon material, which has high tensile strength and is more malleable, thus increasing product life.
  3. We strictly produce according to the number of layers required by our customers and control all the production processes.
  4. Our inflatable rubber fenders use high-quality truck and plane tires to ensure product quality and long service life.

Types of Fenders

There are various types of ship fenders available, each designed to suit different berthing conditions and vessel sizes. Some common types include cylindrical fenders, D-shaped fenders, W-shaped fenders, and cone fenders. The selection of the fender type depends on factors such as ship size, berthing velocity, tidal conditions, and the specific requirements of the docking facility.

Cylindrical Type(type CY) Rubber Fender

Feature:

  • Low reaction force,less surface pressure, reasonable energy absorption
  • The simple figure is easy to be installed and maintained.
  • Widely used in shipping and docks.
  • Good adaptability for transversal and longitudinal shape during berthing
  • Used as the suspending equipment of defending dash for all kinds of the shipping and docks.
  • Products of other sizes can be manufactured at users’ requests
