28 Jul 2020: Update 28th July 2020: Fugro has begun the geophysical survey phase of a large multidisciplinary site investigation contract worth around GBP 55 million for ScottishPower Renewables’ (SPR’s) East Anglia Hub project. The phased site investigations are scheduled to finish at the end of 2021. Operating from dedicated geophysical survey vessels, the Fugro team began the UXO surveys in July; full coverage bathymetric surveys and sub-bottom profiler surveys across the site and export cable routes will follow. Data processing and reporting will be completed in Fugro’s UK and Netherlands offices. Geotechnical investigation of the wind turbine locations will start later this summer and will comprise ultra-deep seabed cone penetration tests (CPTs) using Fugro’s innovative SEACALF® Mk V DeepDrive CPT system, downhole and seismic CPTs, geotechnical sampling, and geophysical borehole logging. Shallow geotechnical testing and sampling will be performed along the export cable routes, while standard and advanced soil testing will take place at Fugro’s soil laboratory testing facility in Wallingford, UK. Update: Works at EA2 are expected to start on the 20th July. Update: Fugro will undertake geophysical and geotechnical surveys in parallel of EA1N and EA2, with 2020 operation starting in July and ending in October. Up to six vessels are planned to be used for operations, starting with Atlantis Dweller and Fugro Frontier. If the MMO licence is approved (see event 15/01/2020), SPR hopes to conduct geotechnical surveys of the wind farm and export cable corridor of EA1 North and EA2 from April to end-September 2020. It is envisaged that two vessels will be used, with ~15 boreholes/wind farm and ~60 vibrocores/export cable corridor.
