[Introduction] Cable damage and power failure caused by anchoring damage will cause serious economic loss and social impact. In order to reduce the risk of anchor damage accident of submarine cable, a risk assessment method of high-voltage submarine cable anchoring accident is proposed. [Method] According to the cause of the accident, this paper divided the anchor damage accident into two cases: anchor dropping accident and anchor dragging accident, and modeling and calculation were carried out for these two cases respectively Based on the research of single cable anchor damage risk, the anchor damage risk of multiple cables was studied. [Result] According to the model calculation results, it is concluded that the number of cables, warning distance and ship speed are the important influencing factors of anchor damage accident. Meanwhile, with the decrease of cable number, the increase of warning distance and the increase of ship speed, the risk of high-voltage submarine cable anchoring accident will be effectively reduced. [Conclusion] The proposed model can effectively evaluate the risk of high voltage submarine cable anchor damage accident, and provide theoretical guidance for the protection and optimization design of submarine cable.
