摘　　要：本文介绍了海上石油平台的海缆在线监测系统的组成,包括:“海缆温度监测系统”、“海缆应力监测系统”、“海缆扰动监测系统”。分别描述了各系统在线监测原理及功能。以渤海某平台间26/35kV海底电缆接地故障为例讨论了海底电缆在线监测系统未能有效预警的原因,提出了针对海上石油平台海缆在线监测系统预警准确率提升方案。指出了海上石油平台海底电缆监检测领域的机遇与挑战。This article introduces the composition of the submarine cable online monitoring system for offshore oil platforms,including the submarine cable temperature monitoring system,submarine cable stress monitoring system,and submarine cable disturbance monitoring system.It describes the online monitoring principles and functions of each system separately.Taking the grounding fault of a 26/35kV submarine cable between a certain platform in Bohai Sea as an example,this paper discusses the reasons why the online monitoring system of submarine cables failed to effectively warn,and proposes a plan to improve the accuracy of early warning for the online monitoring system of submarine cables on offshore oil platforms.It points out the opportunities and challenges in the field of submarine cable monitoring and testing for offshore oil platforms.
