Norfolk’s only offshore windfarm has suffered a second production setback in a matter of weeks.
The power output from the Scroby Sands windfarm, off Yarmouth, has had to be significantly cut back while emergency repairs are carried out to one of the three cables that bring electricity ashore at the resort’s North Beach end.
The glitch comes less than two months after the giant jack-up barge Sea Energy clipped a blade on one of the farm’s 30 turbines, snapping off the tip.
Jon Beresford, manager of the Eon-run windfarm, said they had known about the cable fault for several weeks. While it had been possible to bring electricity ashore employing just two cables without affecting production, this was not the case during the repairs because other circuits had to be shut down.
He said: “It is likely to take a matter of days because we have to assess the situation.”
A Health and Safety Executive inquiry was launched in October when a turbine blade was damaged by one of Dutch barge Sea Energy’s huge legs, which provide a stable working platform by anchoring themselves to the seabed.
Engineers on board had been carrying out work to replace turbine generators and other parts that had experienced unforeseen wear and led to a number of breakdowns.
Mr Beresford said: “All but 10 of the generators have been replaced but the rest of the work has been postponed until the spring because of the bad weather and the expense of keeping the barge in the harbour.”
Teething problems were responsible for Scroby Sands falling 10pc short of its generating target in the first year of operation.
