摘要：为了保障FPSO单点系泊系统电滑环运行安全，有必要开展电滑环故障诊断方法的研究，为单点系泊系统电滑环故障预警与排查提供依据。本文针对FPSO单点电滑环故障的诊断问题，采用了一种基于CART决策树算法的故障诊断模型；进一步利用有限元制作样本数据集，并通过该数据集训练得到了电滑环故障诊断模型；最后，通过后剪枝法完成了诊断模型的简化，实现了对电滑环的故障诊断。分析结果可以得到，该模型具有较高的准确率和较快的诊断速度，能够对电滑环进行有效的诊断，以便工作人员及时采取措施修复或更换电滑环，保证FPSO的安全运行。

Abstract:In order to ensure the safety of electric slip ring system， it is necessary to carry out the research on the fault diagnosis method of electric slip ring. This method could provide the basis for the fault warning and troubleshooting of single point mooring electric slip ring. In this paper， a fault diagnosis model based on CART decision tree algorithm is adopted to diagnose the single point electric slip ring fault of FPSO. The sample data set is made by finite element method， and the fault diagnosis model of electric slip ring is obtained by training the data set. Finally， the diagnosis model is simplified by the post pruning method， and the fault diagnosis of the electric slip ring is realized. The analysis results show that the model has high accuracy and fast diagnostic speed， and can effectively diagnose the electric slip ring， so that the staff can take measures to repair or replace the electric slip ring in time to ensure the safety and normal operation of the FPSO.

Key words:electric slip ring,fault diagnosis,CART decision tree,FPSO,single point mooring system
