摘要

1. Risk based maintenance optimization described in the paper provides necessary material to a pipeline company to put a comprehensive pro-active Risk Management Program (RMP) in place that allows creating of a computerized in-house segment-ranking tool that supports planning and scheduling of rehabilitation projects. It also provides all necessary support to an alternative regulatory approach, which allows pipeline companies greater flexibility to define company - and pipeline - specific risks and developing company - specific solutions where appropriate. The outlined maintenance system is an attempt to institutionalize an integrated, cross-functional approach to identifying and managing risk. The described above system can be considered as the risk management technology benchmark, because it is providing a level of protection that is above and beyond the current regulations. 2. The industry of manufacturing of the ILI instruments and providers of ILI services should voluntarily conduct a series of benchmark laboratory and field experiments. The main purpose of these experiments should be producing an industry precision standard and specs for each type of ILI instrument to further enhance pipeline operation safety. 3. The current methods of defect detection are not optimal. They don't provide for proper assessing efficiency of the ILI instrument and qualification of the diagnostician due to absence of false defects, of a priori probabilities of their presence or absence, and of empirical choice of decision making threshold. 4.SEC in collaboration with WEKT Co. created a software package that provides a system approach to statistical analysis and interpretation of the ILI measurement data. 5.The developed basic block-module of pipeline risk control allows one to find and/or optimize the following: the trigger levels w and a; time interval between inspections; renewal times; reliability function; quality of maintenance, and to link the trigger levels with the ultimate permissible level of conditional probability of failure to risk-based optimal maintenance planning. At the same time it ensures pipeline integrity and minimizes the risk of its performance. 6.Application of ROFC methods shows the real value of refining the information gathering process. It links engineering and financial parts of a pipeline company graphically, shows all decision elements from input to output and can be reused with new inputs screening a full group of possible scenarios to make the best future decision and cast predictive maintenance as an investment. 7.Application of the optimal cessation of performance problem allows solving the task of prioritizing piperuns with respect to their maintenance and repair, based simultaneously on economic and safety considerations. 8.The maintenance cost for pipelines maintained according to outlined above theory is reduced by up to 12%, with the average raduction being 5-7%.

ILI仪器的制造行业和ILI服务的提供者应自愿进行一系列基准实验室和现场试验。这些实验的主要目的应该是为每种ILI仪器制定行业精度标准和规格，以进一步提高管道操作的安全性。 3.当前的缺陷检测方法不是最佳的。由于没有虚假缺陷，存在或不存在的先验概率以及决策阈值的经验选择，它们不能提供对ILI仪器的正确评估效率和对诊断师的资格。 4.SEC与WEKT Co.合作创建了一个软件包，该软件包提供了用于统计分析和解释ILI测量数据的系统方法。 5，开发的管道风险控制基本模块使人们可以发现和/或优化以下内容：触发水平w和a；两次检查之间的时间间隔；更新时间；可靠性功能；维护质量，并将触发级别与条件故障概率的最终允许级别与基于风险的最佳维护计划联系起来。同时，它可以确保管道完整性并最大程度地降低其性能风险。 6.ROFC方法的应用显示了完善信息收集过程的真正价值。它以图形方式链接管道公司的工程和财务部门，显示从输入到输出的所有决策元素，并且可以与新输入一起重用，从而筛选出整个可能的场景组，以做出最佳的未来决策，并将预测性维护作为一项投资。 7.应用最佳性能问题停止功能，可以同时基于经济和安全考虑，解决对管道进行维护和维修的优先任务。 8，按照上述理论进行维护的管道的维护成本最多可降低12％，平均费用为5-7％。
