2013, EGS, London Array, Geophysical Export Cable Route Survey series https://portal.medin.org.uk/portal/start.php?tpc=015_1407c884-1fda-4006-8831-5e72fb775ece In August 2013 EGS International were commissioned to carry out bathymetric surveys of the London Array Export cable routes. The Bathymetric surveys were to cover the 4 export cables corridor as laid and with a buffer of 25m either side of the outermost cable. The vessel mobilisation was carried out in Ramsgate between 27th and 30th August 2013. The bathymetric survey work was carried out onboard the Wessex Explorer between 27th August and 09th September 2013. The survey equipment was demobilised from the vessel on 9th September 2013 in Ramsgate. Data were collected in ETRS89 Datum with RTK corrections supplied from LAL (Dong London Array) /Dansurvey setup. The VORF model was utilised to reduce data to LAT and for comparative purposes a surface with a fixed offset of 42.1 was also created in order to compare the 2010 and 2013 datasets. Data comparison between the 2010 and 2013 datasets show general movement of sediment in certain areas along the route with the majority of sandwave migration occurring in the outer cable route east of the Kentish flats. 20220523T12:13:20
