Rubber Fender Types And Precautions

In the maritime industry, rubber fenders mainly serve as protective buffers to absorb collision energy when ships contact docks or other vessels. Many people may not realize that large sea vessels often hang rubber fenders along their outer surfaces. Some even refer to them as rubber bumpers. Ports also install rubber fenders directly on piers to protect both the structure and approaching vessels.

The main function of the rubber fenders on the dock is to absorb collision energy during the berthing process. In return, this protects the ship and dock after a collision. Solid rubber fenders have been used for a long time because they are easily available and are considered long-lasting. Rubber fender types come in different forms, including inflatable, drum, cone, cylindrical, square, etc. All of these rubber fender types are unique in their way and have different specifications and uses, as discussed below.

Rubber fender type—pneumatic fenders

Pneumatic fenders serve as one of the most effective anti-collision solutions in marine operations. They actively protect ships during ship-to-ship (STS) transfers and ship-to-berth dockings. Their biggest advantage lies in their ability to absorb large amounts of energy while producing low reaction force on the hull. Operators often use them for rapid response and emergency protection on tankers, gas carriers, and bulk carriers. Most pneumatic fenders meet ISO 17357 standards and come in a wide range of sizes to suit different vessel needs.

Rubber fender type—cell rubber fender

Super cell rubber fenders are also known as SC rubber fenders. Its main features include low reaction force and high energy absorption capacity. They are more durable and suitable for use at offshore terminals.

Rubber fender type—cone rubber fender

The super cone rubber fender, also known as a CO solid fender, withstands severe shearing forces by effectively utilizing its tapered body. With their high level of elasticity, they are more commonly used in large port construction.

Rubber fender type—arch rubber fender

Arch rubber fender type features a simple design, and the arched fenders also provide incredible shear performance, making them suitable for vessels that allow for higher hull pressures.

Things to note when choosing various types of marine rubber fenders

Rubber fenders come in various types, and their quality can vary by manufacturer. When choosing rubber fenders, it’s important to consider several key factors. These fenders offer high energy absorption, low reaction force, and a well-designed structure that ensures long service life. You should also pay attention to the quality of the rubber materials. High-quality rubber extends the product’s lifespan and offers better long-term value.

Shandong Nanhai has been providing a variety of solid rubber fender types and marine fenders for over 15 years. The manufacturing process of our marine prop balls is particularly innovative because we use a different molding technology than most other factories that use traditional manufacturing. As a result, our products have a smoother surface and longer shelf life.
