In the world of marine construction, rubber fenders have become an integral part of various major projects such as the construction of ports, docks, jetties, and maritime terminal facilities. This product serves as a structural protector capable of absorbing the impact energy of ships during docking, as well as preserving the integrity of marine infrastructure from long-term damage. In Indonesia, the use of rubber fenders is expanding along with the increasing number of national strategic projects in the port and maritime logistics sector. This article provides a comprehensive discussion on how rubber fenders are applied in marine construction projects, their benefits for design and operational efficiency, and real examples of successful use of local products.
Examples of Port and Jetty Projects
As an archipelagic country, Indonesia has hundreds of active ports and industrial jetties, ranging from general ports to specialized docks for mining, energy, and oil-gas facilities.
Some examples of projects using rubber fender applications:
-
Patimban Port, Subang
This national strategic project requires a high-quality fender system for large container ships. Cone fenders and frontal panel units are used for maximum protection.
-
Coal Jetty in East Kalimantan
This jetty serves coal transport ships up to 70,000 DWT. Cylindrical rubber fenders are used due to their quick installation and suitability for concrete dock structures.
-
LNG Terminal in Bontang
Gas terminal facilities require fenders with high energy absorption and resistance to extreme sea conditions. Cone fenders with steel plates are used to maintain tanker ship stability.
-
ASDP Ferry Ports
At several ferry ports such as Merak and Bakauheni, rubber fenders are used to protect the busy entry and exit routes of ferries on a daily basis.
The Role of Rubber Fenders in Structural Design
In the technical design of marine construction projects, rubber fenders are part of the structural protection system. Their function is not merely as an accessory but is carefully considered in engineering design.
Functions in design:
-
Reducing the impact forces that the dock structure must withstand.
-
Stabilizing interactions between ships and structures during tides or high waves.
-
Extending the service life of docks or jetties by preventing direct damage to concrete and steel structures.
-
Providing a safe docking zone that supports mooring system design.
Rubber fender design is tailored according to factors such as:
Impact on Operational Efficiency
Proper use of rubber fenders has a direct impact on the operational efficiency of ports or industrial docks. Here are some of the benefits experienced:
-
Faster Docking Process
With a good fender system, ships can dock faster and safer without drastically reducing speed, meaning loading and unloading processes can start sooner.
-
Reduced Maintenance Costs
Protected dock structures do not require expensive periodic repairs due to cracks or deformation from impacts.
-
Enhanced Safety
Fenders help reduce ship vibrations and shifts that can pose risks to crews and port workers. This is especially important for busy ports or industrial docks handling hazardous materials.
-
Supports 24-Hour Operations
High-quality fenders allow ports to operate at night or in less-than-ideal weather conditions without the risk of damage.

Success Stories of Local Product Use
Amid the dominance of imported products, many Indonesian rubber fender manufacturers are beginning to demonstrate quality and competitiveness. One success story comes from Cahaya Sakti Pratama, which has supplied rubber fenders to various national strategic projects.
Case Study:
Project: Revitalization of Pelindo Dock – Sumatra
Challenge: The dock frequently suffered damage due to medium-sized passenger ship impacts.
Solution: Replaced the old fender system with local rubber fender products, type arch and cone, from domestic vendors.
Results:
-
Shorter ship mooring time
-
No structural damage 12 months post-installation
-
Project completed on time and cost savings compared to using imported products
Advantages of using locally made rubber fenders:
Conclusion
Rubber fenders are not just additional protection in marine construction projects but are an essential part of an efficient, safe, and sustainable operational system. From major ports to industrial jetties, proper selection and installation of fenders can optimize facility performance and reduce long-term costs. With the growing number of maritime projects in Indonesia, supporting high-quality local rubber fender products is a strategic step — both economically and technically.
