The scope of work included: 1. MBES and SSS survey of 100m wide corridor along Export Cable Route between the windfarm substation and landfall site, to the east of Clacton-on-Sea. 2. MBES survey the seabed of an area 2400m x 100m around and between six adjacent turbines, namely A6 to F6. This series covers survey elements which were undertaken on the 1st September 2010 around turbines A6-F6, and the 22nd – 23rd September 2010 along the Export Cable Route. The survey work was carried out using the PLA survey vessel ‘Verifier’, with bathymetric data being collected using a hull-mounted Reson SeaBat 8101 MBES and SSS data using a CMAX CM2 sonar.

MBES and SSS survey of 100m wide corridor along Export Cable Route between the windfarm substation and landfall site, to the east of Clacton-on Sea [See Figure 1a]. 2. MBES survey the seabed of an area 2400m x 100m around and between six adjacent turbines, namely A6 to F6 [See Figure 1b]. This report covers survey elements which were undertaken on the 1st September 2010 around turbines A6-F6, and the 22nd – 23rd September 2010 along the Export Cable Route. The survey work was carried out using the PLA survey vessel ‘Verifier’, with bathymetric data being collected using a hull-mounted Reson SeaBat 8101 MBES and SSS data using a CMAX CM2 sonar. The export cable route was clearly visible in the data set. No exposures of the export cable were seen in the data.
