The invention discloses an
underwater structure detection and cleaning operation
system and method applied to a deepwater jacket platform. The
underwater structure detection and cleaning operation
system comprises a mother ship, a crane, a power
repeater, an
underwater operation
robot and an
umbilical cable. The crane is fixed to the
gunwale or the
stern of a
deck of the mother ship, the mother ship lifts the power
repeater and the underwater operation
robot through an
umbilical cable, the underwater operation
robot and the power
repeater are together laid underwater from the ship, and when the underwater operation robot and the power repeater reach a preset position, the power repeater retracts and releases the underwater operation robot through a built-in underwater
winch; when the underwater operation robot works, the underwater operation robot is connected with the power repeater through the photoelectric-hydraulic integrated cable; the power repeater is adopted to play a connecting role in the
system, the high-pressure water preparation device, the underwater
winch and the photoelectric-hydraulic integrated cable are installed in the power repeater, various requirements for detection and cleaning of the underwater structure of the deepwater oil and gas platform are met, and the economical efficiency of underwater operation is greatly improved.
