The London Array Offshore Wind Farm (OWF) is situated approximately 20 kilometres (km) to the northeast of the Kent coast, within the “Knock Deep” Channel of the Thames Estuary. The OWF consists of 175 Wind Turbine Generators (WTGs) and 2 substations. The export cable route, consisting of four cables, runs for approximately 52km from a landfall site at Seasalter in the Swale to the two substations located on the OWF site. Figure 1 shows an overview of the London Array OWF site and export cable.
Both pre-construction and post-construction bathymetric surveys have been carried out on the OWF site and export cable routes since 2010. EGS International Ltd (EGSi) carried out a post-construction bathymetric survey of the export cable in September 2013, in order to monitor changes in seabed morphology against the 2010 pre-construction survey.
In Spring 2014, DONG Energy contracted EGSi to carry out a post-construction bathymetric survey of the export cable route, selected WTGs and connecting array cables.
