2005, Quest Underwater Services Ltd, Kentish Flats Offshore Wind Farm Post Construction Debris Survey Diving Confirmation series https://portal.medin.org.uk/portal/start.php?tpc=015_df3ef902-65e2-4185-b90d-b17ac7b24935 A post construction survey was carried out by EMU Ld between 23 September and 8 October 2005. A single beam echo sounder and sidescan sonar collected data which was compared with the pre construction survey data. Analysis of this data by EMU suggested that 10 of the 52 targets identified were possible debris. The aim of Quest Underwater Services Limited was to dive the 10 targets and confirm that they were not debris left as part of the windfarm construction process. Seabed features were found that explained some of the sie scan sonar echoes. No construction or other debris was found. A certificate was issued on 13 July confirming that no construction debris had been left on the seabed. 20060713
