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

目标：-提供一个可应用于整个道路排水网络的全生命周期成本模型框架。-制定排水系统性能评估制度，以便NR能够彻底认识到排水不良的影响。-识别系统中的高风险/关键排水资产。这将为更强大和更经济的维护计划奠定基础。-分析现有资产的剩余资产寿命和恶化模式，以帮助维护陈旧的排水资产。-建立一个决策支持工具，帮助NR根据预算和风险确定排水工作的优先顺序。潜在结果：-增加资产知识-深入了解排水系统的能力和性能。-预算规划-通过WLC模型，考虑寿命支出，这将有助于总体预算预测和分配。-决策支持-WLC方法帮助资产管理公司为NRS排水系统做出全面而有力的战略管理决策。-降低风险-详细研究铁路排水系统将使NR能够了解其弱点，并控制(如果不是消除)与排水系统故障相关的风险。-改善服务-将排水系统保持在所需的性能水平将减少对火车运营商的干扰，并提高乘客铁路网的可靠性。-改善声誉-如果发生更少的意外事件，与邻居的关系将得到改善，这可以通过设计更好的维护的排水系统来实现。新奇：尽管WLC在许多部门被广泛使用，但它还没有应用于英国的铁路网。这个项目将提供一个为英国铁路排水系统量身定做的全寿命成本模型，考虑到与铁路业务运营相关的成本的独特性和复杂性。-WLC模型的范围既是战略的，也是战术的。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预算规划。在战术层面上，WLC可以应用于单个资产，为路线工程师提供每项资产的更新、维护和使用选项。-与其他管道系统(如配水和废水处理)不同，WLC可以在这项工作中充分实现和评估铁路排水的水力性能，并与WLC联系起来。与其他系统中复杂的互联系统相比，铁路排水系统相对简单，因为它们通常只由两到三条平行的管道组成，因此需要分析的计算能力较小。

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.
