- Make a plan for keeping hardware in good shape to avoid failures.
By focusing on these points, we can keep rubber fenders working well. This means they can protect boats and docks better, lasting longer.
Managing Abrasion and Wear Patterns
It’s important to manage how fenders wear out. Abrasion happens when fenders rub against things, like boats or docks, and wear down.
Common Wear Zones and Causes
Wear spots on fenders often show up where they hit things a lot. This can be because of bad docking, fenders not installed right, or tough sea conditions.
Abrasion Reduction Techniques
To lessen wear, there are a few things we can do. Here are some good strategies:
- Use UHMWPE faces on the fender where it wears out a lot.
- Make docking procedures better to reduce uneven wear.
- Put in guide structures to help direct the boat to the right spot on the fender.
| Abrasion Reduction Technique | Description | Benefits |
| Sacrificial Wearing Faces | Attaching UHMWPE faces to high-wear areas | Protects the underlying rubber, easy to replace |
| Optimized Berthing Procedures | Controlled vessel approach and docking | Reduces irregular abrasion, enhances fender lifespan |
