Immediate search operations
If the Minerve sank in an area where the depth exceeded 700 meters, the submarine's hull, crushed by the pressure, imploded, leaving no chance of survival for the crew. The search will focus on the coastal strip where the depth does not exceed this limit.
The goal sought and to be achieved is to save the survivors who may still exist in the hull of the submersible.

Name of research vessels and location
If by some miracle the submarine ran aground in a shallow area while returning to Toulon, it would have a maximum of 100 hours of reserve oxygen. So we will search far from the area where the Minerve was last spotted; once the 100 hours have passed, there is no more hope.
100 hours after the disappearance, emergency search operations are abandoned
