Metadata: 2004, HydroSoil, Greater Gabbard, Geotechnical Survey
Abstract:
Hydro Soil Services was contracted by Greater Gabbard Offshore Wind Ltd. to undertake a geotechnical soil investigation at the site known as Greater Gabbard situated approximately 26 km of the Suffolk Coast at Felixstowe. The purpose of the geotechnical investigation was to provide data on the ground conditions to assist in the design of wind turbine foundations at the site. The investigation was performed from the Hydro Soil Services Self Elevating Platform “Vagant” and comprised four locations, two on the Galloper bank and two on the Inner Gabbard bank. The investigation included a combination of sample boreholes, SPT and CPT at each location. The operation was performed from 02 September 2004 to 26 September 2004. Sample boreholes were drilled from the first moonpool in “Vagant”. In uncohesive deposits a bailer drilling technique was used, disturbed samples were taken at 1,5 m intervals. In cohesive deposits a core drilling technique was used to recover undisturbed samples every 1,5 m. Standard Penetration Tests were performed at 1,5 m intervals over the full length of the borehole. Simultaneously CPT test were performed from the second moonpool in the “Vagant”, positioned approximately 13,4 m from the first moonpool. Laboratory tests are performed on soil samples by Soil Mechanics UK. This document represents the Factual Report and contains a general description of the work including information regarding the fields operations: equipment utilised, the records of events through the works and a summary of locations, type and depths of the exploratory boreholes carried out. Also include is the report of the laboratory works and a description of the soil conditions.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | On behalf of Greater Gabbard Offshore Wind Ltd. Hydro Soil Services was contracted to undertake a geotechnical soil investigation at the site known as Greater Gabbard situated approximately 26 km of the Suffolk Coast at Felixstowe. HSS received the instruction to proceed with the soil investigation from GGOWL on 09 August 2004, the final contract documents were signed 10 September 2004. The Clients representative on board was Rambøll. The work entails carrying out a campaign of offshore soil investigation including: • Borings for soil investigation and sampling: offshore core drilling to a depth of maximum 50 m below seabed with taking of disturbed and undisturbed samples for laboratory analyses and SPT’s. • Cone penetration tests with the measurement of pore water pressures (CPTU): offshore electrical cone penetration tests with the measurement of pore water pressures (U2) during penetration. |
