Scour protection work is due to recommence within the Gwynt y Môr Offshore Windfarm on the 21st September 2014.
As AWJ Marine informs, the work will be carried out by the vessel Tideway Rollingstone.
All vessel traffic is asked to keep at least 500m clear of Tideway Rollingstone.
Gwynt y Môr will consist of 160 turbines and is being built by RWE Innogy UK (formerly RWE npower renewables) in Liverpool Bay, off the North Wales coast.
Once operational, Gwynt y Môr will have an installed capacity of 576MW, using Siemens 3.6MW turbines and generators.
It will be capable of generating enough energy to meet the average annual energy needs of around 400,000 homes.
The wind farm is due to be fully operational by the end of 2014.
