Abstract:The submarine cable project is an important part of the cross-sea power grid construction project, and the submarine cable is an indispensable power "lifeline", which realizes the grand strategic goal of long-distance transmission of electric energy in China. With the increasing number of submarine cable lines, submarine cables often suffer various types and varying degrees of damage due to complex Marine environment and various external human factors, and the failure of submarine cables in offshore areas due to ship anchor hook is becoming more and more serious. In view of the submarine cable is easily damaged by ships, this paper puts forward that the functional analysis of emergency intervention and disposal of intelligent navigators in submarine cable protection area has important protection measures for submarine cable, and has certain guiding significance for the implementation of such projects in the future.
