Fugro starts East Anglia Hub survey

Fugro has begun the geophysical survey phase of a site investigation contract worth around £55 million for ScottishPower Renewables’ (SPR’s) East Anglia Hub project.

The phased site investigations are scheduled to finish at the end of 2021 and support the development of wind farms in the UK southern North Sea over an area of more than 800 km2. The results from Fugro’s site characterisation will feed into SPR’s ground models for the East Anglia Hub and support seabed mobility assessment, foundation design and cable-route engineering.

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.

Richard Hill, Fugro’s proposal manager for the project, said: “This is a significant and exciting project for Fugro that will see us deploying multiple geophysical and geotechnical vessels from our fleet to the East Anglia Hub for the next 2 years. Fugro’s innovative technologies, experienced geophysical and geotechnical survey teams, and large capacity for advanced soil testing laboratory in the UK will be crucial in helping SPR to meet their project timescales.”

SPR’s East Anglia Hub consists of East Anglia One North, Two and Three which have been merged into one single delivery programme with a combined capacity of around 3,100 MW. The company aims to begin construction in 2022, and envisages a four year construction period to complete the entire East Anglia Hub. The initial 1,400 MW (East Anglia Three) already has planning consent. Planning applications for the further 1,700 MW (split between East Anglia One North, and East Anglia Two) have been submitted.

The three sites will eventually consist of 263 wind turbines capable of delivering a total installed capacity of up to 3.1 GW, enough to power up to 2.7 million homes.

Earlier today (28 July 2020), SPR announced that its East Anglia ONE offshore wind farm is now operational. All 102 Siemens Gamesa offshore wind turbines – situated 43km off the Suffolk coast – are operational, with the capacity to produce 714 MW of clean energy
