Service Life
Pneumatic rubber fenders (also known as Yokohama fenders) are high-pressure floating fenders made of reinforced rubber layers with synthetic tire cord. They provide outstanding energy absorption and low reaction force, making them ideal for ship-to-ship (STS) and ship-to-dock (STD) operations, oil & LNG terminals, large container vessels, and offshore platforms.
Types of Pneumatic Fender
Two main configurations to meet specific application requirements
Type-I: Net type fenders
Pneumatic fender covered and protected by chain, wire, or fiber net with rubber sleeves and tires for additional protection.
Type-II: Sling type fenders
Lightweight design without chain & tyre net covering, offering flexibility and ease of handling for various marine applications.

Pneumatic Fender FAQ
Most ISO 17357-1:2014 pneumatic fenders are designed for 50 kPa (low-pressure type) or 80 kPa (high-pressure type) when fully inflated at 20 °C.
During service, the internal pressure should be checked regularly and maintained within ±10% of the rated value.
With correct pressure maintenance and periodic inspection, a quality pneumatic rubber fender typically lasts 8–10 years or more.
Lifespan depends on usage frequency, environmental conditions, and proper storage.
Yes. We provide third-party inspection and certification such as ABS, CCS, BV, DNV, LR, and other class society reports on request.
Mill test certificates and ISO 17357 compliance documents are included as standard.
Selection is based on vessel displacement, draft, approach speed, and berthing energy.
For VLCCs (Very Large Crude Carriers) or large LNG carriers, diameters of 3.3 m–4.5 m and lengths of 6.5 m–9 m are common.
Our engineers can calculate the optimal size and quantity once you provide basic ship data.
Clean and dry the surface to remove salt or debris.
Keep inflated at about 50% of working pressure or deflate and fold if long-term storage is planned.
Store in a cool, shaded, well-ventilated area, away from direct sunlight, ozone sources, and sharp objects.
Rotate the fender periodically to avoid flat spots.

Product Testing
After the product is completed, in order to ensure the quality of the product, we will conduct self-test or third-party testing agency testing according to customer requirements, such as BV or SGS testing institutions, the testing content includes product size and weight and the most important compression testing. Our factory has its own large fender pressure testing machine, which performs the compression test of the product and generates a report. Before the test, the Pneumatic fender must remove the outer tire sheath or rope net and leave only the body.

Packaging
The size and number of pneumatic fenders determine the way of packing. We have rich experience in packing. Normally larger fenders will use deflation to pack. We will give a set of inflatable fenders. Equipment, the customer can inflate and use the product normally after receiving the goods

Application
Pneumatic rubber fender has been widely used in oil tankers, container ships, yachts, offshore platforms, large docks, military ports, large piers, etc.
The Pneumatic fender uses compressed air as the buffer medium to absorb the impact energy of the ship so that the ship can be more flexible and soft when docked, so as to achieve the effect of collision prevention, collision avoidance, and avoidance. Thus it is widely used in the transfer operation between ships and the berthing operation of ships.
