Marine Fenders International, Inc. manufactures the Ocean Guard™ Donut Monopile floating fender exclusively. The Ocean Guard ™ Donut Monopile floating fender design is an innovative foam filled fender. This unique fendering system provides a floating, energy-absorbing foam filled fender. It is designed to simply slip over a stationary monopile and float at the fluctuating water line.
Upon contact with a ship or vessel, this design allows the fender to freely rotate and self-adjust with the changing water level. The unique rotating feature also makes it ideal for turning dolphins and eliminates shear forces. Where there are large or extreme tidal fluctuations a mooring crown can be constructed into the fender to allow safe moorage during the tidal swings. This can also be accomplished when the fender is compressed.
The Ocean Guard™ Donut Monopile floating fender construction consists of:
- A tough, thick filament nylon tire cord reinforced non-marking urethane skin.
 - 100% closed cell heat laminated energy-absorbing foam core
 - Heavy-duty internal structural steel core
 - Anti-friction bearing pads
 - Custom designs and shapes
 
The Ocean Guard™ Donut Monopile floating fender has many applications:
- Breasting Dolphins
 - Bridge protection
 - Corner protection
 - Dock fendering where large tidal changes occur
 - Dock fendering where vessels need roll along fenders for loading
 - Ferry vessel applications
 - Lock entrance
 - Turning dolphin applications
 
The Ocean Guard™ Donut Monopile floating fender performance features:
