Case Analysis of Emergency Repair of Three Core 220 kV Submarine Cable in Inshore Wind Farm

Combined with a case of three core 220 k V submarine cable emergency repair in an offshore wind farm in China,this paper introduces the deployment scheme of the barge,boat and excavator,the fault point locating and salvage scheme of three core 220 k V submarine cable,as well as the safety guarantee measures for the construction of offshore submarine cable repair. It will be a feasible reference case for similar offshore repair cases,which has important implications for submarine cable repair project of the offshore wind farm and oil ＆ gas project.
