2 4 2 PNUMATIC FNDRS Pneumatic fenders are ideal for permanent and semi-permanent port applications and for offshore ship-to-ship transfers. They are supplied in a wide range of sizes and in standard or high-pressure versions. Smaller fenders can be supplied as Hook type. arger fenders are commonly fi tted with a chain-tyre net (CTN) for added protection. For navy ships, a grey body is also available. Features asy and fast to deploy Very low reaction and hull pressure Suitable for small and large tidal ranges Maintains large clearances between hull and structure Applications Oil and gas tankers Fast ferries and aluminium vessels Temporary and permanent installations Rapid response and emergencies Abrasion-resistant rubber skin 3 Airtight rubber layer 2 Multi-layer reinforcement 4 Inflation valve

5 4 5 HYDRO- PNUMATIC FNDRS Submarines and other vessels which contact fenders below waterline require a unique solution. Hydropneumatic fenders are specially adapted to this application. The fender body is partially water-filled, then pressurised with air and ballasted to make it stand vertically. Fender draft and performance can be tuned by altering the water:air ratio and inflation pressure. Features Sub-surface contact face Very low hull pressures Variable draft Prevents acoustic tile damage D Sea evel Applications Submarines Some fast ferries Semi-submersible oil rigs Air Water ength Due to the very specialist nature of Hydro-pneumatic fenders, it is strongly advised that a detailed study be carried out for each case.
