Component Specifications

Definition
The Fender Body is the primary structural element in marine fendering systems, designed to absorb kinetic energy through compression or deflection when vessels make contact with docks, piers, or other marine structures. It serves as the main energy-absorbing component that distributes impact forces across the fendering system, preventing structural damage to both vessels and port infrastructure. These components are engineered to withstand repeated impacts, environmental exposure, and varying load conditions while maintaining their protective function.
Working Principle
Operates on energy absorption principles through material deformation (compression, shear, or bending) or pneumatic/hydraulic mechanisms. When a vessel contacts the fender, the body compresses or deflects, converting kinetic energy into heat or stored energy through elastic or plastic deformation, thereby reducing impact forces transmitted to the vessel and dock structure.
Materials
Typically manufactured from high-grade rubber compounds (natural rubber, SBR, EPDM, or polyurethane), composite materials, or specialized polymers with additives for UV resistance, ozone resistance, and marine environment durability. May include steel or aluminum reinforcement plates for mounting and structural integrity.

Frequently Asked Questions

What is the primary function of a fender body?

The primary function is to absorb and dissipate kinetic energy during vessel berthing impacts, preventing damage to both the vessel and dock structure by reducing transmitted forces.

How often should fender bodies be inspected?

Regular visual inspections should occur monthly, with comprehensive technical inspections annually or after significant impact events, checking for cracks, deformation, wear, and mounting integrity.

Can fender bodies be used in freshwater and saltwater environments?

Yes, but material selection must account for environmental factors—saltwater requires enhanced corrosion resistance for metal components and specific rubber compounds to resist marine organisms and chemical exposure.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
