METHOD OF THE UNDERWATER FACILITY PROTECTION Russian patent published in 2018 - IPC B63G8/33 

FIELD: active protection devices.

SUBSTANCE: subsea facility protection method using the submersible guardian device (SGD) is in the SGD preparation for launch by the on-board control system (BCS) testing, to which the movement program and the task are entered. Launching the SGD from protected facility or carrier, switching on the BSU into operation, by which commands controlling the SGD movement. Calculating and adjusting the path, using the navigational instruments updating the geographical coordinates, maneuvering the SGD and keeping the set position and depth. Detecting the target and attacking using the mines or performing the target audible or visual warning of its detection. As the SGD, using the autonomous uninhabited underwater vehicle with propulsion unit and power-generating unit, including chemical current source and electric motor. Equipping the SGD and the protected underwater facility with mutual recognition devices, monitoring the SGD location using the radio and / or laser communication lines.

EFFECT: enabling the underwater facility secret protection using the SGD and SGD operations remote control, in case of foreign targets detection, warning them, announcing alarm or attack.
