Norfolk Marine’s TFN System for Elisa Prototype

Norfolk Marine’s Tyre Filled Net (TFN) system will be installed as scour protection for the foundation of the 5MW Elisa prototype under construction in the Canary Islands.

The TFN system will be installed on the turbine foundation inshore in controlled port conditions complimenting the projects “Off Site Construction” technology.

Esteyco, leader of the developer’s consortium, commented: “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 fabricated from recycled materials reducing the environment impact of offshore developments.
