Hydro-pneumatic Fenders Description

Hydro-pneumatic Submarine Fenders are widely used in scenarios such as submarine docking, maintenance, and offshore operations. Fenders can provide effective protective support when submarines enter and exit ports, dock, or perform other underwater operations, ensuring the safety and security of the submarine hull. In addition, fenders are also suitable for the protection needs of water facilities such as offshore platforms and large shipyards, providing strong guarantees for the safe berthing of ships and facilities.

Submarine inflatable fenders achieve their cushioning function through compressed air filled inside. When the submarine approaches the dock or other docking facilities, the fenders can absorb and disperse the impact force from the submarine, thereby reducing direct damage to the submarine hull and docking facilities. At the same time, the design of the fender also takes into account the special characteristics of the underwater environment, using corrosion-resistant and wear-resistant materials, and undergoing special treatment to enhance its stability and durability underwater.

Installation Instructions
The uniqueness of design
Hydro-pneumatic Submarine fenders for submarines are a special version of dock fenders designed specifically for submarines. This type of fender combines partial filling of water and air, and is equipped with counterweights to ensure that it maintains a vertical position in the water, effectively protecting the submarine's hull.

Hydro-pneumatic Submarine Fenders Advantages


Advanced Air-Water Composition

Engineered with a precisely adjustable air-to-water ratio (typically 30%-70%), allowing for tuning to specific berthingconditions.


Superior Energy Absorption

Designed to provide exceptional energy absorption (e.g., up to 3,151 kNm for the largest model), effectively protecting vessel hullsduring contact.


Reliable Vertical Stability

Features an integrated counterweight system that maintains optimal vertical positioning with minimal deviation (±2°), ensuringconsistent underwater protection.


Customizable and Low-Maintenance

Offers custom-designed solutions through professional engineering analysis and features a low-maintenance designresilient to harsh marine environments.


High-Pressure Resilience

Built with enhanced burst strength exceeding standard fenders and includes safety valves for overpressure protection.


Versatile Underwater Application

Specifically designed for submerged protection of submarines, certain ferries, semi-submersible oil rigs, and naval vessels innavy ports
