Our elastomer component is designed to replace existing rope and chain mooring systems, formed through an innovative molding technique that allows it to withstand high cycles of repeat low-force events. This makes it ideal for use in a high-energy marine environment, easing the movement of the floating structure during wave motion.
As shown in the stress-strain response diagram, the elastomer is capable of better controlling the tension that holds the floating structure in place, providing protection against sudden shock loads and reduction in peak loads on the system, while providing ample redundancy in carrying loads of up to 30 tonnes.
The elastomer provides the benefits of a catenary mooring system while producing a largely reduced footprint, and can be added in line with existing chain mooring systems. By installing alongside an existing mooring line, the tether will primarily bear the mooring loads, with the existing chain remaining in place as a fail-safe.
If the elastomeric mooring solution has a high enough elasticity or length, then the device can oscillate freely with the wave motion providing only a minimal restoring force. This can substantially reduce the maximum force on the system, enhancing survivability, reducing costs and increasing its lifespan.

The Elastomer is compatible with our Thermoplastic Springs for a comprehensive tethering solution.
