Professional diving

Scuba divers are professional divers capable of operating in any underwater environment to carry out inspection, construction, maintenance and demolition tasks. Waterways, the offshore energy sector and the world of industry are part of their working environment.

Rapid and safe intervention by scuba divers, at the very heart of the customer’s installations, avoids long interruptions of water-based industrial processes or costly dewatering operations.

The lack of visibility, the depth, the pollution do not constitute obstacles for them but rather daily challenges which must be met with all safety and quality requirements.

Interventions in this type of environment obviously require extensive skills. This is why only true professionals have diplomas recognized by the IDSA (International Diving Schools association) and/or the IMCA (International Marine Contractors Association) and constantly update their knowledge.
