Option 3
The third option uses floaters made out of a UV-protective
shell filled with unsinkable foam (Figure 3.82). The
barrier has a freeboard of one meter above the water line,
and below the waterline a skirt can be attached to the
barrier. The floatation pieces are bolted together which
enables the option to place the skirt between them.
Pros
• Rigid floaters
• Skirt can be attached to the buoys relatively easy
Cons
• Expensive compared to fenders
• Time-consuming installation
Concluding remarks
Based on the input from multiple fender manufacturers,
the reliability of pneumatic is uncertain for a deployment
time of 10 years. Hence, we will now assume foam-filled
fenders in this feasibility study. However, considering the
benefits in terms of transportability, deployment time
and recyclability, it is still recommended to further investigate
the suitability of pneumatic fenders in a later
phase.
