Product Introduction
Marine Fenders Full Product Brochure
(Pneumatic Rubber Fenders / Foam Filled Fenders / Yacht Small Bumpers)
1. General Introduction
This full marine fender product line covers three core series: ISO standard pneumatic rubber fenders, heavy-duty closed-cell foam filled fenders and lightweight yacht bumpers. All products strictly comply with ISO 17357-1:2014, PIANC marine design standards, and have obtained full global classification society approvals including CCS, DNV-GL, BV, ABS, LR, SGS.
Adopting imported mature manufacturing technology combined with independent optimized production craft, the series realizes full-size customization from small yacht bumpers to D4.5m super-large fenders. The complete system matching includes protective tire net, hot-dip galvanized chain, lifting lugs and inflation accessories, providing all-in-one anti-collision buffer solutions for cruise ships, LNG carriers, VLCC tankers, ro-pax vessels, naval ships, offshore platforms, river terminals and offshore STS ship-to-ship transfer projects.
Three product lines cover differentiated application scenarios:
Pneumatic fenders: High energy absorption & low reaction force, ideal for offshore STS overloading, large oil terminals
Foam filled fenders: Unsinkable, zero maintenance, suitable for remote offshore platforms, military vessels and long-term unmanned berths
Yacht bumpers: Lightweight & scratch-resistant, for private yachts, fishing boats and inland leisure vessels
2 Core Product Series & Technical Parameters
2.1 Pneumatic Rubber Fenders (ISO 17357 Standard)
Also called Yokohama-type floating fenders, manufactured by integrated whole winding vulcanization craft without splicing seams. Natural rubber content ≥56%, multi-layer synthetic tire-cord reinforcement, air leakage rate only 1%–2% (far below ISO 4% limit). Two types: net-covered type & sling type.
Main Standard Sizes & Performance (60% Compression, P50 Initial Pressure)
| Diameter × Length (mm) | Reaction Force (kN) | Energy Absorption (kNm) | Applicable Scenario |
|--------|--------|--------|
| 500×1000 | 64 | 6 | Small fishing boats, yacht docks |
| 1000×1500 | 181 | 32 | Inland cargo ships, medium terminals |
| 1500×3000 | 579 | 153 | Container vessels, coastal wharves |
| 2500×4000 | 1008 | 368 | Ro-pax, medium oil tankers |
| 4500×9000 | 4437 | 3356 | VLCC, LNG ship STS transfer |

Core Advantages
Ultra-high energy absorption, low hull reaction force to avoid paint & steel plate damage
Self-floating, automatically follows tide fluctuation without fixed brackets
Light weight, easy to move & deploy for temporary berth & STS operations
Complete supporting hardware, one-stop supply without separate procurement
2.2 Closed-Cell Polyurethane Foam Fenders
Adopt imported foam forming & PU cladding technology, unsinkable design with closed-cell EVA foam core, thick filament-reinforced PU outer skin. No inflation required, no risk of puncture failure.
Main Performance Features
Unsinkable structure: Skin scratch will not lose buoyancy, no pressure inspection needed
Progressive energy absorption curve, 30% lower reaction force than pneumatic fenders under equal energy absorption
Anti-abrasion PU skin, service life ≥15 years
Optional accessories: rotating lifting lugs, full tire chain protection net
Standard Sizes Range
Diameter: 0.5m ~ 4.5m; Length: 1.0m ~ 9.0m, custom color available
Core Advantages
Zero daily maintenance, no inflation & pressure detection work; perfect for offshore wind platforms, naval warships, remote unmanned docks and large bridge anti-collision projects.
2.3 Yacht Special Mini Bumpers
Lightweight vinyl integrated molding, dual inflation valves, horizontal & vertical dual hanging structure, multiple bright color options, no scratch to yacht paint.
Standard Models
F series: F1 / F2 / F3 / F4 / F5
A series: A0 ~ A7
Size range: 15×64cm ~ 30×76cm, buoyancy 18lbs ~ 45kg
Core Advantages
Standard spot inventory, fast delivery; flexible hanging way, widely matched with private yachts, speedboats and fishing vessels.
