SME engineers utilized the advanced finite element analysis software ANSYS to meticulously construct a detailed 3D finite element model of the fenders. Through this model, they simulated the stress distribution and deformation of the fender’s front panel across various regions and under multiple operating conditions. This process aimed to comprehensively evaluate the mechanical properties of the fender structure, ensuring its stability and durability under various external loads. Based on the exhaustive simulation analysis data, the SME team was able to comprehensively consider various factors and tailor an optimized design solution to meet the performance requirements and safety standards for specific application scenarios.
The structural form of the frontal panel
In the Fender system, the structural configuration of the frontal panel is typically determined according to the type of fender and specific design requirements. It is often paired with various types such as Cell fenders, Arch fenders, Cone fenders, and Leg fenders. The frontal panel can be designed in either an open or closed configuration. However, we recommend the closed configuration due to its superior strength, excellent corrosion resistance, and prolonged service life. The closed design not only reinforces the overall strength of the frontal panel but also provides a better protective barrier against corrosive media, ensuring long-term and stable performance of the Fender system.

Surface Pressure
The frontal panel is designed with the functionality to reduce the pressure on the ship’s surface, capable of keeping the surface pressure below 200KN/m². This feature makes it particularly suitable for berthing large ships. Furthermore, the front panel may also be equipped with UHMW-PE pads, which are fixed to the frontal panel, to lower the coefficient of friction between the ship and the fender system. This effectively prolongs the service life of the Fender system.
Corrosion Prevention
Corrosion resistance is a vital consideration for the long-term operation of fender systems. Given their exposure to the harsh marine environment, it is imperative to adopt effective corrosion prevention measures. SME employs a multi-layer corrosion prevention system, featuring a triple-coat structure of primer, intermediate coat, and topcoat, or alternatively, an overall galvanized surface combined with a topcoat, all of which meet stringent painting standards. This ensures the sustained and reliable operation of Fender systems over time. Additionally, we have innovated by attaching sacrificial anodes to the bottom of the front panels, further enhanced the anti-corrosion performance.
Face pads
The face pads, as an integral part of the frontal panel, are securely fastened to it with mechanical bolts. Its design and material selection are crucial in reducing the coefficient of friction during berthing, protecting both the hull and the fender system itself.
SME has opted for a proven UHMW-PEmaterial, renowned for its exceptional wear resistance. Even under conditions of frequent contact and friction, UHMW-PE maintains its integrity over an extended period, resisting scratches and wear with remarkable durability.
The face pads can come in a variety of colors, such as vibrant yellow, serene blue, subdued black, or a clever combination of multiple hues. These rich color options not only add a splash of brightness to the fender system but also enhance the visibility and visual identity of the dock. In a maritime or riverside environment, such color design helps ensure that vessel operators can clearly identify the dock location during berthing or departure, thereby improving operational safety and efficiency.
