以全生命周期费用理论为基础,统筹考虑管道设计、材料、施工和运行维护水平,同时设计中考虑建设投资、生产运行成本和后期管道失效潜在损失等管道全生命周期费用,提出了管道的全生命周期费用模型。在满足安全性的前提下,进行全面技术经济比选,综合比选各个方案在满足目标可靠度、同一工程项目工况条件下,在管道全生命周期内最优的管输设计方案。在保证管道安全的前提下,以达到管道经济性的最优,最终实现设计、材料、施工和运行操作等方面的统一。
Based on the life-cycle cost theory, the pipeline design, material, construction and operation and maintenance levels are all considered in an integrated manner. In the meantime, the entire life cycle cost of the pipeline, such as construction investment, production and operation costs, and the potential loss of later pipeline failure, is considered in the design. Life cycle cost model. Under the premise of meeting the safety, a comprehensive technical and economic comparison and comparison was conducted to comprehensively compare and select the optimal pipeline design solutions of each solution in meeting the target reliability and working conditions of the same project. In the premise of ensuring pipeline safety, in order to achieve the optimal pipeline economy, the final realization of the design, materials, construction and operation of the unification.
