EDF Enérgies Nouvelles has invited tenders for two jobs at the Saint Nazaire Offshore Windfarm site located on the French coast (Pays de la Loire – Loire Atlantique).
The first job is to conduct an offshore geotechnical campaign. The campaign will include drilling shallow geotechnical boreholes using a rotary coring system to typically 2m below the seabed. This scope will consist of 30 – 80 shallow geotechnical boreholes.
The second tender relates to performing an offshore geophysical assessment survey (BAS) for inter-array cables at the site that will include seismic refraction and potentially seabed survey and other soil profiling means. The estimated inter-array cable length to investigate is approximately 110km.
Last year in April, EDF and Alstom won three of five batches of the 10 billion-euro ($13.3 billion) worth contract for the development of French offshore wind farms.
