LES EOLIENNES EN MER DE DIEPPE LE TREPORT (EMDT) selected the Soacsy multibeam sub-bottom profiler seaCHIRP TM3D to carry out a geophysical survey on Dieppe-Le Tréport Wind Farm site. The survey was performed in the Spring of 2018. Its purpose was twofold:
- first, to determine whether potential explosive devices (UXO), and especially low magnetic contents ones (LMB), are present in the seabed,
- and secondly, to search for potential archaeological remains.
Two vessels were mobilized. The first one, to perform bathymetry (mapping of the seafloor) and sub-bottom survey. The second one to achieve magnetic detection of objects.
GEOxyz was the survey Main Contractor and SOACSY provided equipment, spare, measurement assistance, on-board and office data post-processing and interpretation.
EMDT is a consortium of Engie, EDP Renewables, and the Caisse des Dépôts.
