High Light Heavy Duty Inflatable Dock FendersRubber Marine Floating FendersBlack Marine Floating Fenders
Marine Dock Bumpers Heavy Duty Inflatable Boat Fender with  High Absorption & Low Reaction
Floating pneumatic rubber fenders, also known as Yokohama fenders, are constructed from synthetic-cord-reinforced rubber sheets with compressed air inside. This design enables them to float on water and serve as effective shock absorbers between ships (ship-to-ship) or between ships and berthing structures during docking operations. All Doowin Marine Yokohama-type floating pneumatic rubber fenders are manufactured and tested to fully comply with ISO 17357 standards.
DOOWIN Marine, as a leading marine equipment manufacturer, announced the production of 4×9-meter Yokohama Pneumatic Fenders.

Developed through continuous R&D, these Yokohama Pneumatic fenders meet the needs of large-scale vessels and ports. They are made of high-quality natural rubber, ensuring excellent elasticity and durability. Tested to meet the ISO 17357 standard, they offer reliable performance.


Equipped with a tire net, which consists of car/truck tires and chains, the Yokohama pneumatic fenders gain extra protection against abrasion and external forces.

Our company provides these Yokohama pneumatic fenders at competitive prices. With central stock positions, we offer fast worldwide delivery.

These pneumatic rubber fenders are suitable for ship-to-ship and ship-to-port applications. We’re confident they’ll contribute to the marine industry’s safety and efficiency and look forward to global partnerships.


Key Features
  • Lightweight design for easy handling and installation with guy-rope or guy-chain
  • Maintains energy absorption level under inclined compression up to 15 degrees
  • Provides low and even hull pressure distribution
  • Multiple synthetic-cord layers with tough abrasion-resistant rubber for consistent performance
  • Minimized maintenance costs and damage risk
  • Self-buoyancy and long service life
Construction Components
  • Outer Rubber: Protects cord layers and inner rubber from abrasion and external forces with excellent tensile and tear resistance
  • Tire Cord Layers: Reinforcement layer that maintains internal air pressure integrity
  • Inner Rubber: Seals the pressurized air within the fender structure

  • Oil & Gas (typically FSRU)
  • Temporary berthing
Product Advantages
  • ISO 17357:2002 Compliant: Manufactured and tested to meet international standards
  • Soft Reaction Force: Doesn't increase sharply under excess load conditions
  • 15° Inclined Berthing: Maintains energy absorption at angles up to 15 degrees
  • Shear Force Resistance: Reinforced with strong tire-cord for combined force resistance
  • Tide Adaptability: Floats freely to accommodate tidal range and ship movement
  • Low Maintenance: Minimal air leakage requires only annual pressure checks
  • Cost Effective: Simple installation and low maintenance requirements

Note: Floating pneumatic rubber fenders are sometimes referred to as "Yokohama Fenders" or "Yokohama type fenders" - ISO 17357:2002 Ships and marine technology -- High-pressure floating pneumatic rubber fenders.
