The load capacity of the cone rubber fender is another critical design consideration. This capacity must be sufficient to handle the maximum impact force that the fender is likely to encounter. Engineers must calculate this force based on factors such as the vessel's weight, the speed at which it approaches the dock, and the angle of impact.

Buoyancy is also an important factor, especially for floating docks or in areas with fluctuating water levels. The fender must be designed to maintain its position and orientation under varying water conditions. This may involve incorporating buoyancy aids or ensuring that the fender's design allows it to float without rolling over.

The way in which the cone rubber fender is connected and mounted to the dock or vessel is another critical design consideration. The connection must be secure enough to withstand the forces involved in docking but also allow for some flexibility to accommodate movement and misalignment.

There are various connection methods, including bolted, clamped, and welded connections. Each has its own advantages and disadvantages, and the choice will depend on factors such as the available infrastructure, the level of maintenance, and the specific requirements of the application.

Finally, the design of cone rubber fenders must take into account environmental considerations. This includes not only the resistance of the rubber to environmental factors such as UV radiation and temperature fluctuations but also the potential impact of the fender on the marine environment.

For example, the use of non-toxic materials and the incorporation of features to prevent the fender from becoming a hazard to marine life are important considerations. Additionally, the fender's design should minimize the risk of damage to the dock or vessel, thereby reducing the potential for pollution from leaks or spills.
