  <dc:description xmlns:dc="http://purl.org/dc/elements/1.1/">London Array Limited commissioned geophysical and geotechnical surveys for the proposed offshore wind farm in the outer Thames Estuary, comprising up to 300 turbines and a 46.5km buried electrical cable connection. Conducted by Osiris Projects and Gardline Geosciences, with oversight by Hydro Soil Services, the surveys employed sonar, vibrocores, Cone Penetration Tests, bathymetric methods, physical sediment sampling, and analysis of geophysical charts and reports to assess seabed conditions and recommend cable burial strategies. 

Findings revealed variable seabed compositions, sediment mobility, biogenic gas presence, and multiple hazards, including magnetic anomalies and debris. Recommended burial depths range from 0.6m to 2.0m, with jet trenching or ploughing for unconsolidated sediments and pretrenching for stiff clay, emphasizing the importance of detailed risk assessment, site-specific geological considerations, and robust burial protection to mitigate threats such as fishing and anchoring.</dc:description>
