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.

PLA’s MCA certified dedicated survey vessel, Yantlet, was used throughout the duration of the project for MBES work (Figure 2). The equipment on the PLA’s vessel is permanently fitted and regular calibrations of equipment are undertaken, including daily field checks. The PLA is ISO 9002 and 14001 certified and all QC documentation are held and available for review. Bathymetric sounding data is generated to IHO S44 Special Order level.
