摘　　要：针对海底管道腐蚀剩余寿命预测的难题,结合海底管道目前最常用的挂片法所能获得的有效数据,推荐了四种适用的剩余寿命估算方法,并进行了案例应用。结果显示利用挂片数据,这四种估算方法都是可行的,但是不同的腐蚀发展模式对剩余寿命的影响是显著的,估算时一定要结合管道实际情况合理选择估算方法,同时对腐蚀挂片监测数据的采集和管理提出了更完善的意见,丰富了海底管道剩余寿命估算的数据来源,给腐蚀管理及工程技术人员提供了有价值的参考。It is a difficult problem to predict the corrosion remaining life of offshore pipeline. Four prediction methods are recommended based on the corrosion coupon data, and was applied in a case. The result shows that the four method are feasible, but different corrosion development model impacts remaining life observably, the selection of the prediction method must take the pipeline specific circumstance into account. At the same time, the more perfect opinion of the coupon data collection and management is suggested, enriching the data source of remaining life prediction, it is a valuable reference for the people doing corrosion management and technology.
