Supper Cell Rubber Fender, SCMarine Fender

SC marine fender is also called drum typefender, as it can be compressed into a drum-shape. It has the followingadvantages:

1. As compared withits counterparts, our high reaction force type rubber fender offers higherrated compression deformation, energy absorption and more.

2. With an impingementplate at the head part, the supper cell rubber fender generates small reactionforce on vessel body. According to customers demands, the reaction force onvessel body can be 25 tons/m2 or less, making the marine fender ideal for largesized vessels.
3. With high energy absorption and reaction force, the SC marine fender isespecially suitable for use on dolphin wharfs.
4. As compared with its counterparts, the supper cell rubber fender has smaller oblique compressiondeformation.
5. The PE veneer installed on the front of theimpingement plate steel frame helps reduce the friction coefficienteffectively.

3.1 The surfaceforce acting across the external vessel body can be calculated according to:FP= R/(LB)
In the above formula,
FP stands for surface force (kN/ m²).
L stands for the contact surface length (m) of the impingement plate.
B stands for the contact surface width (m) of the impingement plate.
R stands for the reaction force (kN) of the rubberfender system.

Hence, when the impingement plate length and width is given, the surface forcecan be achieved. When a specific surface force is given, we can easily get thedesired impingement plate size.
However, while calculating the impingement plate size according to given surfacepressure, please pay attention to the effective arrangement of veneers with thesame specifications.

In addition, the impingement plate should be tailor-made according to the dockdesign, hydrologic condition, and the installation layout for the marine rubberfender system. Hence, customers can contact us for the impingement platedesign.

3.2 Structure of impingement plate

3.2.1 Standard type

3.2.2 Hinge-connection type

Whenseveral rubber fenders are combinedtogether and installed in a line horizontally, the design strength ofimpingement plates may be increased due to the large space between marinefenders. By use hinge-connection type impingement plates, the marine fenderscan also be connected with each other by hinge connection method, thus make theimpingement 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 sealingperformance test should be given while manufacturing this type of impingementplate.

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 11, 21, 31, etc.)

3.3.2Vertical installation layout when the marine fenders are arranged in aline vertically (like 11, 21, 31, etc.)

3.3.3 Combinational installation (like 22, 23, etc.)

4.2 Material
Both flat plates and angle plates are made using UHMWPE, making them featurehigh strength and tensile.

5. Rubber spring chain

Therubber spring chain refers to a chain designed with rubber springs to reduceforces acting on the chain, thus ensuring safety.

5.2 Rubber spring chain specification

5.3 Suspension chain
When the weight of the impingement plate exceeds the allowable load, asuspension chain should be utilized so as to prevent the drooping of the marinerubber 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 aline.

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

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

7. Small performance reduction in oblique compression conditions
Our TD-A type marine fender features smallperformance reduction in oblique compression conditions. This is a greatadvantage when there is a large space between fenders or when the berthingangle is large.
The following chart shows you the correction factors of the rubber fendersreaction force and energy absorption, when oblique compression forces act onthe fender system.

8. Others
Notes to designers:
As shown in the following diagram, when the anchor bolt is embedded into aconcrete structure, the distance between the anchor bolt and the concretestructure 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 theconcrete structure, so as to prevent the mooring dolphin from being damagedwhen the marine rubber fender gets a shearing force or tensile force.
