Novel integrated drainage assessment to improve rail safety and reduce operational costs

目标：-提供一个可应用于整个铁路排水网络的全寿命成本模型框架。-制订排水系统表现评估制度，使新航道能全面了解排水系统不良的影响。-识别系统内的高风险/关键排水资产。这将为更有力和更经济的维修计划奠定基础。-分析剩余资产寿命和现有资产的劣化模式，以帮助维护老化的排水资产。-建立决策支持工具，帮助NR根据预算和风险对排水工作进行优先排序。潜在结果：-增加资产知识-深入了解排水系统的容量和性能。-预算规划-使用WLC模型，将终身支出考虑在内，这将有助于整体预算预测和分配。-决策支持- WLC方法可帮助资产管理公司为nr排水系统做出全面而稳健的战略管理决策。-降低风险-详细研究铁路排水系统，有助北航了解其弱点，并控制（即使不能消除）与排水系统故障有关的风险。-改善服务-将排水系统维持在理想的性能水平，可减少对列车营办商的干扰，并为旅客增加铁路网的可靠性。-改善声誉-如果减少闹事事件，可以改善与邻居的关系，这可以通过设计更好的排水系统来实现。新颖性：-虽然WLC被广泛应用于许多部门，但它尚未应用于英国铁路网。考虑到与铁路业务运营相关的成本的独特性和复杂性，该项目将提供适合英国铁路排水系统的全寿命成本模型。WLC模型的范围包括战略和战术。在战略层面上，它可以帮助资产管理公司对整个排水系统进行未来的预算规划。在战术层面上，WLC可以应用于单个资产，为Routes工程师提供每个资产的更新、维护和利用选项。-与其他管道系统（例如配水及污水处理系统）不同，铁路排水系统的水力性能可在这项工作中得到充分体现和评估，并与供水系统连结。与其他系统中复杂的相互联系相比，铁路排水系统相对简单，因为它们通常只由沿轨道的两个或三个平行管道组成，因此需要较少的计算能力来分析。

Objectives:- Provide a framework of Whole Life Cost model that can be applied across therailway drainage network.- Develop a drainage system performance assessment regime so that NR canhave a thorough realisation of the impact of poor drainage.- Identify high risk / critical drainage assets within the system. This will providethe foundation of a more robust and economic maintenance scheme.- Analyse the residual asset life and deterioration patterns of existing assets inorder to assist maintaining aged drainage assets.- Build a decision support tool that can help NR prioritise drainage work basedon budgets and risks.Potential outcome:- Increase asset knowledge - gain in depth understanding of the drainagesystem's capacity and performance.- Budget planning - with a WLC model, the lifetime expenditure is taken intoconsideration, which will help with overall budget forecasting and allocation.- Decision support - WLC approach helps asset managers to makecomprehensive and robust strategic management decisions for NRs drainagesystem.- Reduce risk - studying the railway drainage system in detail will allow NR tounderstand its weakness and control, if not eliminate, the risks associatedwith drainage failure.- Improve service - maintaining the drainage system at a desired performancelevel will reduce disruption to train operators and increase the reliability ofthe railway network for passengers.- Improve reputation - relationship with neighbours would be improved ifthere were fewer ooding events, which can be achieved with a betterdesigned maintained drainage system.Novelty:- Although WLC is widely used in many sectors, it has not been applied to theUK railway network. This project will provide a whole life cost model tailoredto the UK railway drainage system, considering the uniqueness andcomplexity of costs associated with the railway business operation.- The scope of the WLC model is both strategic and tactical. On a strategiclevel, it can help asset manager with future budget planning on the wholedrainage system. On a tactical level, WLC can be applied to individual asset,providing Routes engineers with a renewal, maintenance and utilisationoption for each asset.- Unlike other piped system such as water distribution and wastewaterdisposal, the hydraulic performance of railway drainage can be fully realisedand assessed and linked to the WLC in this work. Compared to the complexinterlinks in other systems, railway drainage systems it is relatively simple asthey often only composed of two or three parallel pipelines alongside thetrack, and hence require less computational power to be analysed.
