    "description": "Spectrum Geosurvey Limited was contracted by Vattenfall Wind Power Limited to perform a post construction survey on the Kentish Flats Extension offshore wind farm.\r\n\r\nThe primary requirement was to acquire multibeam bathymetry and backscatter data along the Kentish Flats Extension export cables, inter-array cables and surrounding the fifteen wind turbine generators.\r\n\r\nMultibeam bathymetry and backscatter data were acquired on board the survey / crew transfer vessel \u201cSpectrum 1\u201d between the 5th \u2013 11th November 2015.\r\n\r\nAll survey specifications were met and a total of 159 seabed targets larger than 0.5m in any dimension were subsequently identified. All reporting for this survey is contained entirely within this document.\r\n\r\nThe following conclusions were reached following the survey operations and subsequent analysis:\r\n\r\n? 159 seabed features have been identified within the survey area.\r\n? No cable exposures are evident along the export cables and inter array cables.\r\n? The largest shoaling and deepening differences associated with cable installation works between the 2015 Q4 and 2014 Q2 data were +1.15m (mattressing over LAL HV4 & KFE export cable Y2) and -0.8 m (trenching north of HV1 on export cable X4) respectively.\r\n? The largest shoaling and deepening differences associated with spud can footprints are found between the 2015 Q4 and 2014 Q2 data were +0.95m (KFE WTG 05) and -3.15 m (KFE WTG 05) respectively.\r\n? No significant changes were observed over the LAL/KF1 rock berms.",
