Nanjing Taidun explores the critical, sector-specific applications of rubber fenders in shipyards, oil terminals, and container ports—three cornerstones of the global maritime industry. Rubber fenders act as a vital safety buffer, absorbing vessel berthing energy to protect infrastructure, prevent hull damage, and maintain operational efficiency. Shipyards rely on compact, versatile fenders for precision vessel construction; oil terminals use heavy-duty, oil-resistant fenders to mitigate high-risk hazards; and container ports deploy high-energy fenders to handle ultra-large vessels and non-stop logistics operations. Choosing the right fender type (cone, cell, drum, D-type, pneumatic) based on vessel size, environment, and layout ensures long-term safety, cost savings, and uninterrupted maritime operations.
Practical step-by-step guide breaks down the full rubber fender wear and tear inspection process into actionable, easy-to-follow stages, designed for maximum clarity and efficiency for maritime professionals. Starting with pre-inspection safety protocols and essential tool preparation, it covers 8 core inspection steps focused on spotting surface wear, cracks and ruptures, rubber aging, mounting hardware damage, permanent deformation, impact response testing and formal documentation. It also lists non-negotiable warning signs that demand immediate rubber fender replacement and shares proactive maintenance tips to extend fender lifespan. Built for port managers, dock technicians and vessel crews, this checklist enables early wear and tear detection, cuts long-term maintenance costs, eliminates unplanned operational downtime, and ensures consistent safety for port, dock and vessel berthing operations.

Foam fenders Structure
Foam fenders are fabricated with closed-cell resilient foam, with protective tough polyurethane elastomer skin(or tough rubber skin), reinforced with nylon filament, what’s more, protective chain and tire net is option for cushion foam fenders.

A. Foam filled fenders are filled with highest quality resilient closed-cell foam, this specification foam can provide high energy absorption with relatively low reaction force. Even the skin is punctured, it also is unsinkable without absorbing water, with our unique laminating process, each foam core is integrity, the foam core cannot be ruptured when compressed.
B. Guard and Cushion Foam filled fenders’ skin is constructed of polyurethane elastomer which is reinforced with nylon filament. The polyurethane skin is the unique elastomer specifically for fender applications. More thick filaments and elastomer are applied to both ends to better resist the defection and shearing force.
C. Foam Filled fenders are comprised of through central steel tube and external load flanges distributed at each end. All end fitting are H.D.G. Except the through central pipe, all longitudinal chains are joined to Clevis eyes at both ends of the fender.
D. Foam filled fenders incorporate chain and tire net. The chain and tire net design uses heavy duty H.D.G chains, fitted with heavy duty ties at the net intersections. This chain and tire net carry the tensile load, minimizes stress on the fender skin.
E. Chain and net used for the netted type cushion type foam fenders.
F. Rubber foam fenders skin is protected by vulcanized rubber, it is more tough, and with higher performance.
