Claim 8:
9. A method to inspect a tank containing a flammable fluid, comprising:
providing an inspection vehicle, the inspection vehicle including a pressure switch, a propeller, a control unit, an inspection device, a ranging device and a battery providing power to the propeller, the control unit, the inspection device, and the ranging device, the control unit and the battery located within the inspection vehicle;
detecting, by the pressure switch, when a pressure of the fluid external to the submersible vehicle is greater than a predetermined pressure threshold;
closing, by the pressure switch, a circuit between the control unit and the battery after detecting that the pressure of the fluid external to the submersible vehicle is greater than the predetermined pressure threshold;
generating, by the control unit based on data received from the ranging device, a map of the tank,
determining a first position of the inspection vehicle on the map of the tank;
determining, by the inspection device, a quality metric of a portion of the tank by the inspection device;
retrieving, by the control unit from a memory element, a value of a characteristic property of the flammable fluid in the tank;
setting, by the control unit based on the value of the retrieved characteristic property of the flammable fluid, a speed of the propeller;
moving, by the propeller of the inspection vehicle, the inspection vehicle from the first position to a second position within the tank in accordance with the set speed;
determining, by the inspection device, the quality metric for the portion of the tank at the second position within the tank; and
storing, in a data structure stored in the memory element, the determined quality metric corresponding to the second position within the tank.
