Pneumatic Fender Construction

Floating pneumatic rubber fenders consist of an outer rubber layer, reinforcement synthetic-tire-cord layer, and inner rubber, all vulcanized firmly together.

Outer Rubber Layer for Better Protection

The outer rubber protects cord layers and inner rubber, with compounds offering sufficient tensile and tear resistance to withstand weather conditions and severe usage.

High Quality Synthetic-tyre-cord Layer

The reinforcement synthetic-tyre-cord layer maintains internal air pressure, while the inner rubber layer seals the pressurized air inside the fender.

Safety Valve For Safer of Big Size Pneumatic Fenders

Fenders with diameters of 2500mm and larger include safety valves for releasing excess internal pressure. Smaller fenders can be equipped upon request.

Chain and Tire Net Pneumatic Rubber Fenders

The external chain and tire net provide additional protection for the rubber fender body, using truck tires, fiber nets, or aircraft tires that can be easily replaced.

The properties of outer and inner rubber materials comply with ISO 17357:2014 standards. Contact us for detailed material property information.

  • ISO 17357-1:2014 Ships and marine technology -- Floating pneumatic rubber fenders -- Part 1: High pressure
  • ISO 17357-2:2014 Ships and marine technology -- Floating pneumatic rubber fenders -- Part 2: Low pressure
Pneumatic Fender Types

Our Pneumatic Rubber Fenders are available in two common types:

  • Type I - Net Type: Covered with a chain net, wire net, or fiber net for small size fenders
  • Type II - Sling Type: Features lifting devices on each end for connection with guy chains or ropes. Without protection net, offering lightweight and easy handling


Floating pneumatic rubber fenders, also known as Yokohama fenders or Yokohama-type pneumatic fenders, are constructed from synthetic-cord-reinforced rubber sheets with compressed air inside. The internal air enables flotation on water and serves as a shock absorber between ships (ship-to-ship) or between ships and berthing structures. All Doowin Marine Yokohama type floating pneumatic rubber fenders are manufactured and tested to fully comply with ISO 17357.
These fenders can be easily handled and installed with guy-ropes or guy-chains due to their lightweight design. They resist shearing forces and maintain energy absorption levels under inclined compression up to 15 degrees while providing low and comparatively even hull pressure.
Available in diameters from 500 mm to 4,500 mm and lengths from 500 mm to 9,000 mm, pneumatic fenders come as sling-type or with heavy-duty chain & tire net configurations. We also supply vertical hydropneumatic fenders for submarines. Foam filled fenders are another floating fender option.

Floating Pneumatic Rubber Fenders Advantages

Doowin-Marine pneumatic rubber fenders are manufactured and tested to comply with ISO 17357, using Korean production technology.

  1. ISO 17357 : 2002 Compliance: All fenders meet the latest ISO 15375 standards
  2. Soft Reaction Force: Reaction force remains stable even under excess load conditions, protecting ships and mooring facilities
  3. 15° Inclined Berthing: Maintains energy absorption at inclined compression up to 15 degrees
  4. Against Shearing Force: Reinforced with strong tire-cord to withstand combined shearing forces
  5. Lower Mooring Forces: Safely protects ships and mooring facilities in rough weather conditions
  6. Adaptable to The Tide: Floats freely to accommodate tidal range and ship vertical movement
  7. Low Cost Installation: Simple mooring with guy ropes or chains, easily relocated
  8. Low Maintenance Cost: Minimal air leakage requires only annual pressure checks
  9. Ship Cost Minimization: Compact shipping in vacuumed and folded state via containers or pallets
