Donut Fender
The Donut Fenders are made of polyethylene foam with a polyurethane
elastomer shell. Special donut fenders have been specifically designed
to protect the berthing pipes of the vessels. The internal structure is
heavy duty, but it allows the rotation on the support pipe.
The polyethylene foam guarantees unsinkability even in case of
damage and ensures high energy absorption with low reaction force,
which is essential to eliminate the risk of damage to the hulls. They can
be purposely created for any pipe type and any pipe diameter
- Corner protection.
- Turning structures.
- Lead-in jetties.
- Simple breasting dolphins.
- Bridge protection.
