2012-2013, Fugro GEO, Burbo Bank Extension, Geotechnical Investigations series https://portal.medin.org.uk/portal/start.php?tpc=015_2a0e3891-54e6-416d-b7ab-bfdf43b9261a Geotechnical investigations were executed by GEO in 2012 (CPTs and shallow vibrocores) and by Fugro Geoconsulting Limited in 2013 (deep boreholes). Comprehensive geophysical investigations have been undertaken as part of the Environmental Impact Assessment (EIA) of the Project (document number 5.1.2.8 of Development Consents Order application). The geotechnical investigations performed by GEO in late 2012 comprised a total of 33 investigations, comprising; 32 shallow seafloor cone penetration tests (CPT's) as well as 29 vibrocores to maximum depths of 8 m below the seafloor (BSF). The majority of investigations were carried out along the cable route and the remaining tests executed within the proposed wind farm site. The geotechnical investigations performed by Fugro Geoconsulting Limited in late 2012 were a parallel geotech campaign to the GEO work, using a different vessel for deeper water heavy duty coring. This sampling comprised of nine sample boreholes advanced by means of cable percussive and rotary coring techniques (seven penetrated to approximately 45 m, and two went deeper to 60 m) as well as downhole CPT's within the wind farm area. These tests were executed to maximum depths of approximately 60 m. A summary of geotechnical investigations is also provided. 20210517T13:32:28
