A unique system which uses carpets of tyres to protect wind turbines from scour on the seabed could be trialled by a leading energy company.

The technique, which involves placing interlinked tyres around the base of turbines to trap sand, has been developed by Lowestoft-based Scour Prevention Systems (SPS).

Scour, a form of seabed erosion caused by tides and currents, can pose a risk to wind farms by causing vibrations which can damage the turbines.

Now the company has entered talks with global energy firm 
E.on to trial the technique in what could be a significant step towards commercialisation.

The system was an idea of former professional diver Bob Durrant, one of four SPS founders, who had noticed discarded tyres trapping sediment in rivers. The company is investing £300,000 in developing the patented technique, which involves using up to 900 used tyres to form a mat around turbines or oil rigs to slow water flow and capture sediment, creating an even surface.

While the trial has not been confirmed and details have not been finalised, they would involve Scour testing its system at the Scroby Sands wind farm off the coast of Great Yarmouth, which is operated by E.on UK.
