The installation of 48 turbines on the Gunfleet Sands off Clacton, Essex, started on August 25 and is due to be fully operational late 2010.

A 500-metre safety zone has been established around the Gunfleet Sands and yachts are advised to keep well clear, except in an emergency. Working boats will have extremely long anchor cables out and tugs are often towing construction vessels on long tows with very limited manoeuvrability.
