Study on Maintenance Order of Submarine Cable Group Based on Maintenance Priority

Based on the specific maintenance strategy of submarine cable, the maintenance priority of cable is divided into three levels. Firstly, by considering the healthy running state of submarine cables and the importance of transmission tasks carried by them, appropriate methods and models are used to calculate the priority of each cable. Secondly, combined with these priorities, a calculation model of the importance of submarine cable health status is constructed to quantify the impact of the health status of each cable on the system operation. Finally, the validity and feasibility of this method are verified with an offshore platform group as the research background, and the maintenance order established can guide the actual maintenance and management of submarine cables scientifically and reasonably.
