Summary

The London Array 2 Offshore Wind Farm is located in the outer Thames Estuary more than 20 km from the Essex coast. London Array 2 covers an area of approximately 15 x 7 km, consisting of 41 sites with the dimensions 150 x 150 m. Seabed sediments across the area generally comprise of sands and gravel with sand waves occurring extensively across large parts of the survey area. The seabed topography is dominated by the Long Sand and Kentish Knock sand banks which extend south-west to north-east through the project site. The seabed is characterised by localised current induced sediment bed forms. Sand waves of up to 5 m high occur of the flanks and crests of the aforementioned two major sand banks. Water depths within the project site vary between nominally 0 m and 23.5 m below Lowest Astronomical Tide (LAT). A comprehensive bathymetrical and geophysical survey of each planned turbine site was conducted by MMT in 2012. The reports summarise the conditions within the survey sites with regards to; bathymetry and seabed or buried features (e.g. obstacles, manmade targets and cables) detected during the survey. - Side Scan Sonar Data - Magnetometer Data - Multichannel Seismic Data The results from the bathymetrical and geophysical survey are presented within the enclosed report and appendices. The report provides information of the survey performance, instrumentation and processing stages of the work, together with summaries of the survey results.
