Previous surveys have been conducted at 6 monthly intervals from September 2010. The surveys are required for the FEPA Licence Numbers: Gunfleet Sands I & II (GF1L/2011/0064/9 & GF2 L/2011/00065/3) Offshore Windfarm. The scope of work, for the September 2012 survey, was as undertaken in 2010 which included: 1. MBES survey the seabed of an area 2400m x 100m around and between six adjacent turbines, namely A6 to F6. 2. For 2011, a requirement for additional works and analysis identified by DONG Energy, namely: - Volume calculations at each of the six turbine sites, difference surface charts. 3. For March 2012 there was a requirement to delineate the full extent of scour from the turbines. This series covers survey elements which were undertaken on the 1st September 2012 around turbines A6-F6. The survey work was carried out using the PLA survey vessel ‘Yantlet’, with bathymetric data being collected using a hull-mounted Reson SeaBat 8125h MBES.
