海底管道在油气水输送中的安全服役至关重要，一直以来的腐蚀问题也影响着海底管道的服役寿命。复合材料补强修复技术在陆地管道上已经广泛应用，而海底管道的修复中并未展开应用。某海底管道采用复合材料水下缠绕补强修复技术开展了实践应用，通过实践应用证明复合材料水下缠绕补强修复技术是一种安全可靠的补强修复技术。本文将对复合材料水下缠绕补强修复技术的修复材料性能、修复系统的应用设计、修复系统的施工工艺展开介绍。

The safe service of submarine pipelines in oil， gas and water transportation is very important， and the long standing corrosion problem also affects the service life of submarine pipelines. The composite material reinforcement and repair technology has been widely used in onshore pipelines， but it has not been applied in the repair of submarine pipelines. A submarine pipeline adopts the composite material underwater winding reinforcement and repair technology to carry out practical application. The practical application proves that the composite material underwater winding reinforcement and repair technology is a safe and reliable reinforcement and repair technology. This paper will introduce the repair material properties of the composite underwater winding reinforcement repair technology， the application design of the repair system， and the construction technology of the repair system.
