摘　　要：针对当前海上拖航作业失事后果严重、难以进行全线监测等问题,对大型海洋平台拖航作业的风险进行分析,结合事故致因理论从人、机、环境、管理等4个方面构建海上拖航作业安全评估指标体系。在此基础上,提出基于单隐藏层误差反向传播算法的海洋平台拖航作业安全评估模型,将指标数据作为网络输入、单一隐藏层作为中间层、拖航安全的评估值作为网络输出。试验结果表明,所提方法具有良好的精度和鲁棒性,对海上拖航作业具有一定的指导意义。Aiming at the serious consequences of sea towing operation at present and the difficulty in monitoring the whole line,the risk of towing operation of large offshore platform is analyzed,and the safety evaluation index system of sea towing is constructed from four aspects:man,machine,environment and management with the combination of the accident cause theory.On this basis,an offshore platform towing safety evaluation model is proposed based on single hidden layer error back propagation algorithm,that is,the index data are used as the network input,the single hidden layer is taken as the middle layer,and the evaluation value of towing safety is taken as the network output.Test results show that this model has good preciseness and robustness,which can provide some guidance for the towing operation.
