Embodiments provide for safely and reliably operating a generator in a submersible environment utilizing an autonomous control system. One embodiment is a power generation system that includes a generator, a water-tight enclosure surrounding the generator, an intake valve, an exhaust valve, and a controller. The intake valve couples an air intake on the generator to an outside surface of the enclosure. The exhaust valve couples an exhaust port on the generator to the outside surface. If the controller determines that the enclosure will submerge, then the controller stops the generator and closes the intake valve and the exhaust valve. After detecting that the enclosure has surfaced, the controller opens the intake valve, opens the exhaust valve, and starts the generator.
