Marine Fenders

Pneumatic rubber fenders
A pneumatic fender gives enormous advantages in case of tides variations, inclined berthings and when a soft reaction force is required for particular hulls such as cruise vessels or navy ships. Furthermore performance remains the same after years due to compressive elasticity of the air that is not compromised by fatigue like a solid fender.

Hydro Pneumatic fenders for submarines
Vertical-Pneumatic fenders are specially designed to be installed vertically (Hydropneumatic fenders are water-ballasted). They are popular with vessels whose berthing point is below the water line such as submarines, catamaran ships, semi-submersibles platforms or other submersibles.

Pneumatic fenders in Offshore Service
Pedrotec Srl deals from over 40 years in pneumatic fenders market, from sales to rent ,as well as ,on site installation, assistance and repair. Anything related to the aftersale services for pneumatic fenders is our daily business. We started using aircraft tires instead of standard truck tires over 20 years ago to increase the chain net resistance fender body protection and life as well as standoff. We keep being pioneers for innovative solutions for a better pneumatic fenders operational performance. In the last 10 years a special attention
has been given to the offshore fenders operations and their weak points. Pneumatic fenders are often used in open sea in very severe conditions. A common equipped pneumatic fenders will probably not survive at those rough conditions, particular attention has to be used for this applications on chain and tire net and riggings, as well as on mooring systems. Pedrotec can equip a pneumatic fender body in order to survive in open sea and can assist in designing the best mooring system. Mooring system and pneumatic fenders have to be considered as an unique system that should not be designed separately.

"Twister" towing ring
Offshore fenders are permanently subject to continuous stress and rotations. These rotations end in an unavoidable twisting of the mooring rope(s). as a textile rope does not have enough torque to turn a common used swivel the ropes will self destroy quickly. The Twister has a rotative part linked to the fender and a fixed part with an eccentric stabilizer plate on rope side. This will keep the ropes in the same position no matter if the fender rotates.
RMU (Remote Monitoring Units)
The Remote monitoring unit for pneumatic fenders is a Pedrotec production and is unique in the world. It’s a GPS unit with a built in pressure sensor and is installed inside the fender. You can get then position and pressure of the fender wherever you are just with an internet connection, you can daily check pressure conditions of your fender offshore and immediatly find it if lost.
Service and maintenance

Service and repair as well as in complete refurbishment. Safety valve test and inspection New chain and tires net Mooring ropes and accessories

Rubber body unless damage is excessive can be repaired with proven techniques.

Foam filled fenders

Higher energy absorption at same reaction force of pneumatic fenders.

These fenders are very appreciated by the cruise industry as they can be of any colour and do not mark the hull during berthing operation.

Typically used without chain and tires protection.

Cylindrical rubber fenders

This fender has been used for years and still in use for its easy installation and maintenance, usually installed with a steel pipe running inside the fender and 2 or 4 chains.

Suitable for cargo, workboats and heavy hulls ships, not recommended for ro-ro and pax vessels.
