Composite Marine Crush Blocks

FRP Marine Crush Blocks

Our crush blocks are manufactured using Fiber Reinforced Polymer (FRP) composite materials, providing an essential safety solution for locks and dams. Designed to be deployed in narrow spaces between vessels and lock walls, our crush blocks enhance safety by absorbing impact forces and preventing direct contact with the lock infrastructure. In case of an emergency where a person falls into the water, the crush blocks can also be quickly deployed to prevent them from being trapped or injured between a vessel and the lock wall.

FRP vs. Traditional Materials

Historically, aluminum was the material of choice for marine crush blocks due to its superior corrosion resistance compared to wood or steel. However, aluminum requires precise welding to maintain an airtight seal, which can be challenging. As a result, many engineers have transitioned to using FRP for crush blocks due to its ease of molding and durability in marine environments. FRP is not only lighter and easier to handle than aluminum but also naturally buoyant and resistant to corrosion. Our FRP crush blocks feature a fiber-reinforced foam core, allowing them to withstand substantial crushing loads while maintaining buoyancy.

Function and Benefits of FRP Crush Blocks:

1. Impact Absorption — FRP crush blocks for waterfront applications are engineered to deform or compress under pressure, effectively absorbing impact and reducing potential damage to vessels and lock structures
2. Structural Protection — By absorbing impact forces, crush blocks help protect the structural integrity of lock walls, especially in high-traffic areas, ultimately extending the life of the locks and minimizing maintenance costs
3. Enhanced Safety — Crush blocks help reduce the risk of collisions and serious impacts that could lead to delays or costly repairs. This added safety measure allows for smoother navigation of barges and other vessels through confined lock spaces
4. Flexible Placement — Crush blocks can be installed directly on barges as fenders or integrated into lock structures. They are positioned at points most likely to experience contact, such as near gates, entry points, or along the sides and bows of vessels

In summary, FRP crush blocks provide a lightweight, durable and corrosion-resistant solution for marine safety and infrastructure protection. Their design as energy-absorbing barriers ensures safer docking and transit in lock systems while offering reliable, low-maintenance performance in demanding waterway environments.
