FKK fenders are modular types and composed of at least two rubber feet serving as elastic buffers that can have a customized size, steel members to attach these feet to the dock, a mono-block steel shield, low-friction and high-density polyethylene coating, and safety chains where needed. This system’s core advantage is its flexibility: the system can subsequently be scaled, and after an accident, it is possible to replace only the damaged part rather than the whole construction.
Moulded rubber vulcanized under high pressure is the key component of the system serving as fenders. On the dock and shield side, hot-glued thick fastening sheets are embedded. The material is either made of natural or synthetic butadiene rubber. These components are completely non-porous, crack-free, homogeneous and ozone-protected.
Shields that are contacted by the ship’s bulb are designed with a rigid and sealed steel structure. Inside the shield, the first rust is removed and then anticorrosive color is applied. The same dust-removal and painting procedures are also applied on the exterior. Optionally, the shield can also be coated with polyurethane spray having a longer life span. The shield thickness is set in such a way that rigidity is ensured against maximum load to be exerted from the ends.
HIGH DENSITY POLYETHYLENE COATING
A strong friction force occurs between the berthing ship and the fender. If the friction surface of the fender is not small, then the ship attempts to drag along the fender resulting in severe damage. Considering these facts, shields are coated with a thick HDPE layer, with bolt heads embedded. Coating is implemented in appropriately-sized modular segments, allowing partial replacements of any damaged segments.
Anchor studs, chains, bolts, nuts and washers are supplied in hot dip galvanized forms completed with a mounting diagram.
