A mooring component (20) comprises a plurality of different deformable elements (22a-22f) formed of an elastomeric material. The component has a tensile length L and at least one of the elements has a length L' < L. As the mooring component (20) comprises a plurality of different elastomeric elements (22a-22f), each having its own unique elastic (i.e. reversible) stress-strain response, the overall response of the component (20) is a composite elastic response resulting from a combination of the responses of each of the plurality of elastomeric elements (22a-22f). The mooring component (20) can form part of a mooring system for floating devices and sea-based structures such as renewable energy devices, including wave energy conversion devices, tidal turbines and tidal platforms, fish farms, oil rigs and off-shore wind farms, especially in low scope or high variability environments.
