The research combines computer simulations and optimization techniques to design fenders that are both stronger and more efficient. Fenders act as buffers between ships and docking structures. Traditionally, they are made from rubber or hollow structures designed to absorb impact. However, this study introduces a more advanced concept: filling the fender with lightweight foam material. This foam significantly enhances the fender’s ability to absorb energy during both slow (quasi-static) and sudden (dynamic) impacts. Using finite element analysis (FEA), the researchers simulated how foam-filled fenders behave under different loading conditions. This method allows engineers to visualize stress distribution, deformation, and energy absorption in great detail—without needing expensive physical experiments. The results are impressive. Foam-filled fenders show better energy absorption and lower reaction forces compared to conventional designs. In simple terms, they act like high-performance shock absorbers, reducing the force transmitted to both the ship and the dock. The study also highlights that optimizing the foam thickness and structural configuration plays a key role in achieving the best performance. This innovation is closely linked to Sustainable Development Goal (SDG) 14: Life Below Water. Ports and coastal infrastructures are directly connected to marine ecosystems. Poorly managed impacts can lead to structural damage, oil spills, or disturbances that harm aquatic life. By improving the safety and reliability of docking systems, foam-filled fenders help reduce environmental risks and protect marine biodiversity. Beyond environmental protection, there are also economic benefits. Improved fender systems reduce maintenance costs, extend the lifespan of port infrastructure, and minimize downtime. This is especially important for regions that rely heavily on maritime trade for economic growth. Another important takeaway from this research is the power of engineering optimization. The study shows that even with the same materials, changing the internal design can significantly improve performance. This means better results can be achieved without necessarily increasing cost or weight—a key advantage in modern engineering. In everyday language, this research highlights how a hidden structure can make a big difference. A fender may not be visible to most people, but it plays a vital role in ensuring safe and sustainable maritime operations. As global shipping continues to expand, innovations like foam-filled fenders will become increasingly important. They not only protect ships and infrastructure but also help safeguard the oceans that support life on Earth. Because in the end, protecting our seas doesn’t just happen in the water—it starts with smarter design on the shore.
