One end of the submarine cable of an offshore wind farm is connected to the wind turbine, and the other end is connected to a land-based substation or control center. An offshore substation or converter station may also be connected in the middle. The submarine cable plays the role of both "blood vessels" and "nerves" in the operating structure of the entire wind farm. In addition to collecting and transmitting electrical energy, it also has optical fiber units inside, which serve as channels for wind farm communications and submarine cable monitoring signals. There are many reasons for submarine cable failures, mainly fishing activities, anchor damage, sediment movement, laying operations, suspended submarine cables, fish bites, etc., of which fishing activities and anchor damage account for 70%. Submarine cable burial is another major cause. Submarine cables are shallowly buried and easily washed and suspended in the air, especially the submarine cables at the entrance of the wind turbine pile foundation. Long-term swinging causes damage to the submarine cables, and the position with the greatest impact on the submarine cable is the joint.
