French sea and river beds carry a heavy pyrotechnic legacy: aerial bombs, magnetic and acoustic sea mines, shells, torpedoes and underwater demolition charges inherited from both world wars. Along the Atlantic-Channel coast (Le Havre, Cherbourg, Brest, Saint-Nazaire) and in the Mediterranean (Toulon, Marseille, Nice), thousands of explosive items are uncovered each year.
SEMTEC delivers the full subsea UXO chain: marine pyrotechnic desk study, magnetometric survey, visual identification by diver or ROV, neutralisation or relocation. Our operators are NATO STANAG 2143 (IMEC, CMD 1&2) and IMAS qualified.
Marine desk study
Document research: naval archives, war diaries, bombing reports, mooring charts.
Magnetometric survey
Towed magnetometers, gradiometers, AI-assisted target analysis, georeferenced GIS deliverables.
Identification & neutralisation
EOD diver or equipped ROV; in-situ neutralisation or controlled relocation depending on the item.
STANAG / IMAS compliance
Procedures aligned with NATO STANAG 2143 and International Mine Action Standards.
