The SZ-D Fender (Donut Fender) is a ring-shaped, foam-filled fender system specifically engineered to provide reliable berthing protection in environments with fluctuating water levels. Designed for installation on monopoles or piles, the SZ-D Fender is able to move vertically with tidal changes, ensuring continuous and effective contact between the vessel and the fender at all times.

The fender features a central steel monopole core, which delivers exceptional structural strength and long-term stability. Its vertical movement is guided by a low-friction UHMW-PE (Ultra High Molecular Weight Polyethylene) pad, allowing smooth and controlled motion along the pole while significantly reducing friction and wear. This design enhances durability and minimizes maintenance requirements even under demanding operational conditions.

A key performance advantage of the SZ-D Fender is its ability to rotate freely around the monopole. This rotational function greatly reduces friction between the vessel’s hull and the fender surface during berthing and mooring. Rather than rubbing against a fixed fender, the vessel is able to slide smoothly along the donut-shaped fender, which helps prevent hull damage, lowers berthing forces, and improves overall safety.

Combining a robust foam-filled structure with an advanced low-friction guidance system, the SZ-D Fender offers an efficient and dependable solution for ports, terminals, and marine facilities seeking enhanced protection for both vessels and infrastructure in tidal and high-traffic conditions.
