Integration and interpretation report – Bretagne Sud - 2024

TECNOAMBIENTE was contracted by DGEC to undertake geophysical and geotechnical data integration and provide an initial ground model for floating windfarm projects in Bretagne Sud.
The geophysical dataset used for integration consisted in Ultra High-Resolution Seismic profiles (UHRS), acquired by Tecnoambiente, across the OWF area. Multibeam Echosounder (MBES), Sub-bottom Profiler (SBP) and Side Scan Sonar (SSS) datasets were acquired by
SHOM in previous campaigns. Additional MBES and SSS data acquired during the export cable (EC) survey by Tecnoambiente, were factored in the integration.

The objective of this report is to present the integration work performed on the geophysical and geotechnical data sets and provide an initial ground model together with relevant geotechnical parameters to assist the preliminary OWF turbines anchoring design.
