Subsea works, underwater UXO clearance and hyperbaric operations.
SEMTEC, the subsea subsidiary of DEMINETEC Group, brings underwater inspection, marine UXO clearance and hyperbaric works expertise to the port and industrial community of Warsaw (Poland). Our Class II commercial divers — certified under French Decree 2011-45 (hyperbaric class B) and trained to NEDEX/EOD standards — operate on harbours, marine structures, ships' hulls and coastal areas contaminated by 20th-century conflicts.
Warsaw is one of the most heavily UXO-contaminated capitals in Europe. Successive devastations — the September 1939 siege, the 1943 Ghetto Uprising, the 1944 Warsaw Uprising and the systematic German demolition of the city afterwards, the January 1945 Soviet offensive — left the city's soil saturated with unexploded bombs, artillery shells, mortars, mines and demolition charges.
The Polish Armed Forces' patrole rozminowania (army EOD patrols) and the Bureau of Border Guard EOD recover thousands of munitions every year across Mazovia. Hotspots include the Praga and Wola districts, the former Powązki, Bemowo and Modlin garrisons, the Vistula riverbed and the former eastern front lines around Radzymin and Warsaw's eastern suburbs.
Major Warsaw infrastructure programmes — M2 and M3 metro extensions, S2 and S7 expressways, the Central Communication Port (CPK) preliminary works — increasingly integrate pyrotechnic historical studies and magnetometric surveys aligned with NATO STANAGs and the French Decree 2005-1325 reference framework.
Pyrotechnic historical desk study (EHT) and safety study (ESP) for any harbour, river or submerged-works project around Warsaw.
Magnetometric survey of riverbanks, canals and inland water bodies in the region of Warsaw.
Technical works in any industrial facility with submerged basins, tanks or pipelines.
Class II/III diver surveys of inland infrastructure: dams, locks, intake structures.
Subsea pyrotechnic audits, owner's-engineering support and training of local crews.
In the strategic port of Warsaw, SEMTEC mobilises divers, observation ROVs and marine magnetometers to secure basins, jetties, approach channels and anchorages where 20th-century munitions still routinely lie on the seabed.
SEMTEC operates in Warsaw and across Poland from our French bases at La Seyne-sur-Mer (Var) and Wancourt (Pas-de-Calais), our Belgian office in Bruges and our Ukrainian site in Kyiv. Diving spread and naval logistics are mobilised on demand.
Yes. Riverbanks, canals, inland-port basins and reservoirs all fall within our remit. The region of Warsaw contains submerged sites of pyrotechnic interest linked to 20th-century conflicts.
Yes, through DEMINETEC Group. The parent company handles land areas while SEMTEC addresses submerged structures and wet zones on the same project.
Typically 5–15 working days depending on distance and logistics. For Warsaw, plan road transport of diving spread, ROV and mobile chamber.
Yes. SEMTEC holds hyperbaric class-B authorisations, MASE certification and works with a referenced hyperbaric occupational-health service.
