Pneumatic Fender
Pneumatic fender is an ideal STS protection bumper that is strong enough to withstand the damage of hard usage, and it's widely applied to places, like STS dock and STD wharf. Pneumatic fenders mainly consist of three types, including sling type, CTN, and hydropneumatic type. Each type is available in various dimensions. According to the ISO17357 standard, Jerryborg is specializing in offering high-quality pneumatic fenders.
Fully compliant with the ISO17357 standard, Jerryborg's pneumatic fender supplies a variety of specifications and dimensions to meet customer's requests and different application conditions.

Pneumatic Fender Classification
According to international pneumatic fenders, pneumatic fender systems are divided into two categories. From the appearance, there are two types of pneumatic fenders:
1.Initial Pressure 50 Kpa, P50 pneumatic fender
2.Initial Pressure 80 Kpa, P80 pneumatic fender
3.Type I, CTN Type, with chains and tire nets pneumatic fender
4.Type II, Sling Type, without chains and tire nets pneumatic
fender
Pneumatic Fender Structure
Pneumatic fender consists of outer rubber layer, synthetic-tire-cord layer and inner rubber layer. The outer rubber layer is made of special compounds that are strong with high tensile strength and tear strength to better protect the fender from the damage of severe weather conditions and hard usage. The synthetic-tire-cord layer is a composite tire cord with cross shadow lines, which is designed to distribute stress evenly. While the inner rubber layer is specially designed to seal the internal air and prevent any leakage.
① Outer rubber layer
② Synthetic-tire-cord layer
③ Inner rubber layer
Pneumatic Fender Application
Pneumatic fenders are widely used in STS and STD berthing and mooring operations.
1. Ports where tides vary largely
2. Ship to ship oil&gas transfer operations
3. Temporary berthing
4. Fast ferries
5. Permanent installation for dock defense
6. Rapid emergency & response
