Abstract

Port fenders are crucial components in maritime operations, protecting ships and port infrastructure during docking and mooring. They absorb and dissipate kinetic energy, reducing the impact forces between vessels and docks. The fenders are constructed from various materials such as rubber, foam, and plastic, and port fenders are customized to suit different vessel sizes and environmental conditions. Their performance significantly affects port facilities' safety, efficiency, and durability. This study discusses the modification of cross-section fenders to improve the ability to absorb impact energy. This research is a simulation with finite element analysis. There has been a lot of research on the finite element method because planning fenders as an impact energy absorber is complicated and requires many extreme conditions. The cell design fender's reaction force decreased by 25.13% compared to the standard design. This reduction is excellent for protecting the ship from large forces that result in reduced ship stability when the ship hits the fender. The cell design fender's energy absorption ability increased by 10.15% compared to the standard design. The absorption of kinetic energy and its conversion into large deformation provides safety and protects the ship when berthing and docking. The results of this research consider optimal Fender design and manufacturing processes.
