DD / DO Fenders

SME DD/DO Jetty fenders are made from high-strength natural rubber or premium synthetic rubber, without internal steel plates. These pure rubber fenders provide excellent elasticity and wear resistance. They effectively absorb impact energy from vessel berthing or collisions, protecting docks, ships, and other facilities while reducing maintenance costs. The compact base design fits narrow berths, and lengths can be customized to meet various port and operational requirements.

Features

DD / DO Jetty fenders can provide moderate reaction force and energy absorption when absorbing collision energy.

The bottom width of the DD fender (DO fender) is relatively small and can be made into any length.

Suitable for multi-scenario applications.

Good durability and economy.

For navy ships, a grey body is also available.

Description

DD Fender | Cost-Effective Protection for Small Docks and Vessels

DD / DO type Jetty fenders are typically produced using injection molding or compression molding, depending on size and shape requirements. Injection molding works well for complex shapes and precise dimensions, ensuring uniform rubber distribution and smooth surfaces. Compression molding suits larger fenders, providing consistent density and stable performance. Both methods produce durable and reliable fenders with long service life.

Our current DD/DO fender series includes the following sizes:

DD Series: DD100, DD150, DD200, DD300, DD400, DD450, DD500
DO Series: DO100, DO150, DO200, DO250, DO300, DO400, DO500

These Jetty fenders comply with international dock protection guidelines, including the Recommendations of the Committee for Waterfront Structures, Harbours and Waterways (EAU 2004), ensuring safe and reliable performance.

DD / DO fenders are versatile. They can be installed on vessels, small inland ports, or even used as warehouse or loading platform bumpers. Flexible sizes, excellent elasticity, and low maintenance make them ideal for various berthing, collision, and cushioning scenarios. With reliable performance and cost-effectiveness.

📌Quick FAQ – DD/DO Rubber Dock Fenders

Q1: What makes DD/DO fenders different?
Pure rubber, no steel inside. Fixed with external longboard. Simple structure, elastic, and low maintenance.

Q2: What is their density?
Between 1.2–1.3 g/cm³, providing good elasticity and wear resistance to absorb berthing or collision energy.

Q3: Are heavier fenders better?
Not always. Moderate weight with high-quality rubber ensures strong impact absorption and long service life. Too light may indicate structural weakness.

Q4: Can they have surface panels?
No. DD/DO fenders rely on rubber elasticity for protection. No panels help maintain flexibility, durability, and consistent performance
