Stabilisation system for a diver

A portable stabilisation system able to adjust a depth position of at least one diver in an underwater environment with respect to the surface of the water, the system comprising at least one pressurised gas supply source, at least one respiratory gas supply source, at least one inflatable device, and at least one respiratory device configured to enable the diver to breathe respiratory gas from the respiratory gas supply source,

• wherein the system is configured to alternate between:
• an inflation configuration in which, the inflatable device is configured to be inflated, at least in part, so as to reduce the depth position of the diver,
• a regulation configuration in which, the inflatable device is configured to inject or extract gas so as to maintain the depth position of the diver, and
• a deflation configuration in which, the inflatable device is configured to be deflated, automatically at least in part, so as to increase the depth position of the diver,
• and in that the system comprises:
• an automatic controller configured to automatically switch the configuration of the system between any one of the inflation, regulation and deflation configurations, the automatic control device comprising an electronic module configured to assess the depth position of the diver and a control module configured to receive at least one depth data from the electronic module and to determine a control command at least from said depth data, and
• a switch device configured to cooperate with the automatic control device so as to switch the configuration of the system according to at least said control command, the switch device comprising at least:
• a pressurised gas primary inlet configured to cooperate with the pressurised gas supply source,
• a pressurised gas primary outlet configured to cooperate with the inflatable device so as to inflate the inflatable device when the system is in the inflation configuration,
• a discharge module configured to cooperate with the inflatable device so as to reduce the amount of gas contained in the inflatable device when the system is in the deflation configuration by the creation of a pressure differential.
