5 Key issue of Asset Manager: Balancing on the Edge Costs of maintenance Reliability & Revenue Asset Management Safety Asset value 5

6 Investments in Infrastructure Most parts of railway infrastructure systems were constructed in specific periods in the past, which is now reflected in age structure of existing assets. Considering age as a key factor of asset lifetime, the main investment in maintenance and replacement of existing assets will be concentrated in specific periods in future. Key issue of asset manager is then how to distribute costs of planned repairs, reconstructions and replacements while keeping safety and reliability standards. 6

7 Investments in Infrastructure which can be the task for Risk/Condition Based Maintenance approach investments EUR Replacement driven by age of assets costs of replacement A > costs of replacement B Replacement driven by condition of assets Initial construction average asset lifetime Replacement or Reconstruction year 7

8 Risk Based Approach to Asset Management: Principle Asset condition / Risk Low risk Do maintenance in the right time = Plan asset maintenance based on actual asset condition or risk related to asset operation Middle risk High risk Target risk level Repair Potential to detect impending failure critical Immediate action required FAILURE time The issue is how to evaluate Asset Condition Time to react 8

9 Risk Based Approach to Asset Management: Methods 9

10 Risk Segmentation as a Basis for Mitigation Scenarios Segment Significance Measures Plan A Not critical Monitoring, measures not needed Savings B Not critical Monitoring, prepare and plan measures Optimization, plan Y+2 to 5 C Critical Priority measures Priority action, plan Y+1 D Critical Immediate measures, disaster situation Immediate action Subject of Asset planning Immediate action required Asset segmentation in Risk matrix PoF Action Plan Costs of identified actions Lower priority Budget for maintenance Actions to be postponed Higher priority Area 4 Tolerated risks Area 3 Area 2 Unimportant risks Actions to be carried out CoF Area 1 Intolerated risks 10 Actions due to Legislation

11 Risk Based Approach to Asset Management: Steps Identify critical assets Identify risk factors and damage mechanism use standards & experience Setup Routine Collect asset data Asset properties, utilization, condition parameters, events/alarms Evaluate asset condition / risk Risk = Probability of Failure * Consequences of Failure Assessment methods: qualitative, quantitative Recommend actions Preventive actions Inspection intervals Repair / Reconstruction Replacement Immediate actions Schedule and perform maintenance actions 11

12 Data Acquisition Strategies Risk based approaches assume availability of data on asset condition and potential consequences of failure The common methods of data acquisition are: On-line Condition Monitoring Critical assets Short time between symptoms and failure occurence High consequesces in case of failure (safety, costs) Field Inspections Slow degradation mechanism Manual inspections Special type of inspections provided by supplier Asset documentation Asset register with basic asset technical data and documentation Purchase Environmental, population, 3rd party objects data 12

13 Case Study: Wheel bearing monitoring Business Issue: How: Flytoget, a Norwegian railway operator spent an enormous amount of mantime on checking the status of all train wheels. To prevent damage to the wagons and the infrastructure, stringent inspection of all wheelbarrows each day is necessary to be able to keep the ultimate service level of 99% availability. CGI designed, developed, integrated and implemented a the state-of-the-art remote monitoring system for the temperature of all train wheels. It uses active RFID with a temperature sensor, GPS for the real-time location of the train and GPRS for sending the data to the integrated web based system. In the future other sensors can easily be connected to the system if needed. Results: Online real-time information on the location of the trains, combined with temperature level of all wheels. No more manhours spent on manual checking of wheels Threshold detection via a graphical display of all trains, wheels and temperatures. Increased availability through preventive maintenance. 13

14 Case Study: SNCF Mobile Asset Management System Business Issue: The French railway service and infrastructure provider, SNCF, is undertaking a major programme of work to improve the safety and reliability on its 31,000km of railway network. Improved management of it s workforce was a key objective of this programme. SNCF also aims to increase punctuality and safety for its 13,000 daily passenger and freight trains in line with its public service charter. How: Results: CGI implemented a solution which equips SNCF s 800 engineers with wireless handheld terminals to collect and analyse asset data on the condition of the tracks. The device synchronises directly with the central SNCF track asset maintenance database to remove the element of human error in data collection and handling. The solution enables SNCF to increase the timeliness, accuracy and cost efficiency of maintenance and improvement projects. 14

15 Benefits of Risk Based AM Lower outages due to predictive actions (instead of corrective) Maintenance costs optimization due to proper asset life cycle management Managed risk and safety Compliance with standards and regulations Infrastructure operators, that implemented Risk Based approach, report 5%-15% annual maintenance costs reduction (for asset types to be assessed) 15
