复合海缆在线监测研究

Research on Composite Submarine Cable On-line Monitoring

为避免复合海缆在实际使用时因故障对整个电网及采油平台造成影响和损失,对复合海缆在线监测方法进行研究。以复合海缆现状为前提,研究并分析光纤传感技术在海缆检测方面的可能性,并以此提出基于BOTDA技术的分布式监控系统。鉴于BOTDA技术对海缆温度和应变的敏感性以及测量精度和距离的优势,该检测系统可有效实现对复合海缆的在线检测,防止复合海缆因损坏带给平台的经济损失。

To avoid the damaged composite submarine cable impacts the whole power grid and oil production platform, the methods of composite submarine cable on-line monitoring are researched. On the premise of status of composite submarine cable, the possibility of optical fiber sensing technology in the submarine cable testing is analyzed, and a distributed monitoring system based on BOTDA technology is put forward. With the high sensitivity to the temperature and deformation and the advantages of distance and measurement accuracy, the BOTDA technology distributed monitoring system can effectively realize the on-line de- tection of composite submarine cable. It can prevent the platform economic losses by the damaged composite submarine cable.
