Offshore facility evacuation systems

An offshore facility evacuation system comprising:

• a submerged-floating pod (SFP) unit configured to be positioned in a body of water adjacent an offshore facility;
• and
• a SFP station located on the offshore facility and configured to launch the SFP unit from the offshore facility, wherein the SFP station comprises a rails and shuttle block, wherein the shuttle block is configured to advance the SFP unit along the rails to catapult the SFP unit off of the offshore facility,
• the SFP unit comprising:
• a SFP controller configured to control operations of the SFP unit;
• an SFP escape line configured to extend between the SFP station and the SFP unit to provide a path for moving persons from the SFP station to the SFP unit while the SFP unit is floating in the body of water adjacent an offshore facility;
• a SFP landing base comprising an inflatable platform that is configured to be inflated to provide a landing area for persons that move to the SFP unit by way of the SFP escape line;
• a SFP depth control system configured to regulate submergence of the SFP unit relative to the waterline in the body of water adjacent the offshore facility, wherein the submergence is determined based on a top surface of a housing of the SFP unit and a distance below the waterline;
• a SFP location control system configured to control a location of the SFP unit in the body of water adjacent the offshore facility;
• and
• a SFP communication system configured to provide communication between the SFP unit and the SFP station.
