Deep-sea engineering system

The invention provides a deep-sea engineering system. The deep-sea engineering system includes a deep-sea engineering device and a cathodic protection device; the cathodic protection device is arranged on the surface of the deep-sea engineering device; the cathodic protection device includes at least three sacrificial anodes, each sacrificial anode is arranged on the surface of the deep-sea engineering device, and connection lines of the centers of all the sacrificial anodes form a stereo graph or a closed plane graph. In the deep-sea engineering system, the cathodic protection device includesat least three sacrificial anodes, and the connection lines of the centers of all the sacrificial anodes form the stereo graph or the closed plane graph, so the sacrificial anodes are more uniformlydistributed, the deep-sea engineering device can be better protected from corrosion, and the life of the deep-sea engineering device is prolonged. Moreover, the structure of the cathodic protection device is simple, the cost i
