Product Description

Hydro-Pneumatic Fenders
Hydro-pneumatic fenders are designed for contact with vessels below the water line, including submarines, and can also be used for vessel-to-vessel applications. These fenders are partially filled with water and ballasted to float vertically. Performance can be precisely tuned by adjusting the water-to-air ratio and initial pressure.
Each hydro-pneumatic fender is customized based on submarine type or class, considering factors such as water-air ratio, hull shape, berthing type, energy absorption requirements, and jetty design. A detailed case-specific study is strongly recommended for optimal performance.
Key Features
Robust Construction: Puncture-resistant materials for harsh marine environments
Modular Installation: Upper/lower flange openings for efficient water cycling
Fail-Safe Design: Integrated pressure relief valve prevents overcompression
Applications
Military: Naval submarines, semi-submersible platforms
Commercial: High-speed ferries, offshore rigs
