Before active use, the device is inflated, after which it is placed as an airbag between the sides of the vessel and the walls of the berths and piers. This saves the boat from damage, but leads to serious challenges for the fenders themselves. Fortunately, modern technologies and materials for the production of fenders have replaced the old rope baskets or logs wrapped with ropes.
Boat owners are continuously buying fenders for a number of qualities:
- impact, abrasion and stress resistance;
- immunity to sea water and decay;
- resistance to any weather conditions and temperatures;
- non-toxic and environmentally friendly.
The ability of a surface to withstand mechanical loads was established as follows: the surface was subjected to impacts of steel balls falling from various heights, after which it is checked whether cracks have appeared on it and whether it has deformed.
The thickened walls of fender’s chamber and the built-in valve guarantee a constant and stable pressure inside the device.
