Pneumatic Fender Size Chart: ISO 17357 Sizes & GEA/RF Data

Most fender inquiries start with a size question. The vessel class is known, the berthing energy is estimated, but the right fender size is not immediately obvious from a product catalog. Standard pneumatic fenders under ISO 17357-1:2014 range from 500×1000 mm to 4500×12000 mm in diameter × length. Performance is rated at 60% deflection and […]

ISO 17357 Pneumatic Fender Standard: Part 1, Testing & Specs

Most procurement specs reference “ISO 17357” without specifying which part, which fender type, or which inspection clauses apply. The result: ambiguity that leads to mismatched expectations between buyer and manufacturer. ISO 17357 is the international standard for floating pneumatic rubber fenders, published in two parts. Part 1 (ISO 17357-1:2014) governs high-pressure fenders at 50 kPa […]

What Is an FSRU and What Fender System Does It Use?

Most engineers searching this question find conflicting answers. Some sources describe jetty fenders. Others list foam fenders. Neither is correct for this application. FSRU berthing is fundamentally different from jetty berthing — and that difference changes the fender entirely. This article explains what an FSRU is, what that operational difference means, and why pneumatic fenders […]

Yokohama Fenders vs. Foam Filled Fenders: Which is Better?

Choosing between Yokohama type and Foam-filled fenders isn't just about price—it's about understanding failure risks that most manufacturers won't tell you. Yokohama (pneumatic) fenders excel in deep-sea ship-to-ship operations due to their superior elasticity1 and lower transport costs, while foam-filled fenders offer unmatched durability for harsh dockside environments since they cannot deflate. The better choice […]
