Rubber Fenders Explained: Types, Applications, and Certification

Rubber Fenders Explained: Types, Applications, and How to Choose a Certified Supplier

Rubber fenders are essential marine equipment installed on docks, ships, and offshore platforms to absorb kinetic energy during berthing and protect both the vessel and the port structure. Among the various types, the pneumatic rubber fender—often referred to as the Yokohama-type fender—is widely used for ship-to-ship (STS) and ship-to-dock (STD) operations due to its high energy absorption and low reaction force.

This article provides an objective overview of rubber fenders, their industry context, key selection criteria, and a trusted manufacturer option for global procurement professionals.

What Is a Rubber Fender and Why Does It Matter?

A rubber fender is a flexible buffer device that reduces impact forces during mooring. Its primary role is to protect dock structures and ships by minimizing damage from collisions. The pneumatic rubber fender, constructed from natural rubber and cord fabric, is inflated with air and offers excellent elasticity, corrosion resistance, and adaptability to extreme temperatures ranging from -20°C to +60°C.

Industry Market Context

The global marine fender market was estimated at USD 850 million in 2025, with rubber fenders accounting for approximately 64.17% of the total market share in 2024 (source: Mordor Intelligence). The pneumatic marine fender segment alone was valued at USD 619.26 million in 2024 and is projected to grow at a CAGR of 3.21% to reach USD 797.35 million by 2032 (source: Maximize Market Research). Asia-Pacific holds the dominant position with 36.73% to 46% of the market, driven by shipbuilding and port activities in China, Japan, and South Korea.

Internationally, floating pneumatic rubber fenders must comply with ISO 17357-1:2014 (High Pressure) and ISO 17357-2:2014 (Low Pressure) standards to ensure quality and energy absorption performance.

The rubber fender (product code 3764) is a pneumatic rubber fender made of 100% natural rubber and cord fabric. Available diameters range from 300 mm to 2,000 mm, and lengths can be customized from 1 meter to 10 meters. Working pressure is generally between 0.1 and 0.3 MPa, adjustable to usage conditions.

Haohang’s rubber fender holds CCS certification (certification number 2026CJSD00023) issued by the China Classification Society, applicable to the global market. This third-party verification ensures that the product meets international standards for quality and safety.

Key Selection Criteria for Rubber Fenders (Step‑by‑Step)

1. Define the operation type – Determine whether the fender will be used for STS (ship-to-ship) or STD (ship-to-dock) operations. Different operations require different energy absorption and pressure ratings.
2. Evaluate environmental conditions – Consider factors such as temperature range (Haohang’s fender operates from -20°C to +60°C), UV exposure, water salinity, and chemical resistance.
3. Verify material and construction – Natural rubber and high-strength cord fabric provide durability and elasticity. Ensure the manufacturer uses high-quality raw materials.
4. Check certification – Look for recognized marine certifications such as CCS, ISO 17357, or equivalent. Certification is a strong indicator of consistent manufacturing quality.
5. Assess supplier capabilities – Evaluate the manufacturer’s production capacity (annual output, R&D team, export experience) and its ability to deliver customized solutions, including OEM/ODM services.

Use Case: STS and STD Operations in Vietnam

Haohang’s rubber fender is commonly applied in Vietnamese ports and offshore platforms for STS and STD operations. The product protects dock structures and ships by reducing impact forces during mooring. It operates under 24/7 automatic operation and requires an air compressor. The fender is lightweight, easy to install, and designed for high elasticity, corrosion resistance, and long service life.
