Supper Cell Rubber Fender, SC Marine Fender

3.2 Structure of impingement plate

3.2.1 Standard type

3.2.2 Hinge-connection type
When several  rubber fenders are combined together and installed in a line horizontally, the design strength of impingement plates may be increased due to the large space between marine fenders. By use hinge-connection type impingement plates, the marine fenders can also be connected with each other by hinge connection method, thus make the impingement plate system lighter.

3.2.3 Enclosed type
Enclosed type impingement plate is composed of veneer and back support plate, so as to increase the structure strength. Water pressure test and sealing performance test should be given while manufacturing this type of impingement plate.

3.3 Layout methods for impingement plates

3.3.1 Horizontal installation layout  - when the marine rubber fenders are arranged in a line horizontally (like 1×1, 2×1, 3×1, etc.)

3.3.2  Vertical installation layout – when the marine fenders are arranged in a line vertically (like 1×1, 2×1, 3×1, etc.)

3.3.3 Combinational installation (like 2×2, 2×3, etc.)

5.3 Suspension chain
When the weight of the impingement plate exceeds the allowable load, a suspension chain should be utilized so as to prevent the drooping of the marine rubber fender.
The weight in the following chart refers to the allowable load (maximum weight) of the impingement plate, when the marine fenders are installed vertically in a line.
Specification Weight (kg) Type 630H 800H 1000H 1150H 1250H 1450H 1600H 1700H 2000H 2250H 2500H 3000H

Note: When the marine rubber fenders are installed horizontally in a line, the maximum weight of the impingement plate is 80% of the value in above chart.

6. The minimum installation space between supper cell rubber fenders
As the marine fender can be compressed into a drum-shape, there should be a proper space between fenders so as to prevent collision.

Specification 630H 800H 1000H 1150H 1250H 1450H 1600H 1700H 2000H 2250H 2500H 3000H

7. Small performance reduction in oblique compression conditions
Our TD-A type marine fender features small performance reduction in oblique compression conditions. This is a great advantage when there is a large space between fenders or when the berthing angle is large.
The following chart shows you the correction factors of the rubber fender's reaction force and energy absorption, when oblique compression forces act on the fender system.
Angle (degrees) correction factor 3 4 5 6 8 10 15
Reaction force correction factor (CR) 0.96 0.94 0.93 0.93 0.92 0.92 0.90
Energy absorption correction factor (CE) 0.94 0.92 0.87 0.87 0.84 0.80 0.72

8. Others
Notes to designers:
As shown in the following diagram, when the anchor bolt is embedded into a concrete structure, the distance between the anchor bolt and the concrete structure surface (L) should be larger than the length of the anchor bolt.
The embedded anchor bolt can also be welded onto the steel frame of the concrete structure, so as to prevent the mooring dolphin from being damaged when the marine rubber fender gets a shearing force or tensile force.
