Norfolk Marine’s tyre filled net (TFN) system is to be installed as scour protection at the foundation of the 5MW Elisa prototype under construction in the Canary Islands.
The system will be installed on the turbine foundation inshore, in controlled port conditions.
Esteyco, the leader of the developer’s consortium said: “TFNs have been chosen as scour protection for the project as they perfectly match with its core objective: minimising offshore tasks and the dependence on expensive and scarce offshore means. And pre-installing the TFNs in-harbour eliminates the traditional anti-scour offshore activity using rock armour.”
The TFN system is made from recycled materials, in an effort to reduce the environmental impact of offshore developments.
According to Norfolk Marine, the system “dramatically” reduces scour and resists sinking in sandy sea beds.
