1 GrDF ASSET MANAGEMENT STRATEGY NEW TOOLS FOR RISK, INVESTMENT AND MAINTENANCE MANAGEMENT Jean Yves Pollard Gaz réseau Distribution France (GrDF) GrDF a subsidiary of the GDF SUEZ Group with industrial assets 188,700 km of network and ductile iron 3 % PE 68 % copper 0,7% other 0,3% steel 28 % steel PE ductile iron copper other Family of facilities (assets) Network pressurereducing station Customer supply station Individual service line Collective service line Facilities (in number of units) 20, ,000 6,500, ,000 Network valve 270,000

2 Asset management practices at GrDF : a consolidation of the fundamentals of asset management listing assets enhancing the geographical information system (GIS) establishing a Computerized Maintenance Management System(CMMS) developing l i an effective feedback procedure Improving the management and relevance of maintenance and investment programmes Methods and tools developed for establishing a hierarchy of investments: Incident Reports Review Incident reports Construct list of critical / high risk asset parks List of Critical Assets List of Critical Assets ORM Annual Budget Allocate Industrial Safety annual budget with Gains ORM tool ORM Optimised Asset Renewals Programme Optimised Asset Renewals Programme Allocate budget for each asset park by region Central Asset Manager Local Project Planner Process Input Process Step / activity Process Output Identify and plan critical asset renewal projects with Project Information for execution by the joint department

3 Integrating three major criteria : safety Pi Principles i of the = Avoided costs / Investments maintenance in operational conditions (operating charges) continuity of service Economic valuation of avoided costs based on full cost approach including: direct costs indirect tcosts induced costs Input tdt data for quantification of the different gains Network technical description: facilities, customers Description of network environment : population, homes Failure data defined per nature of incident and type of facilities Economic valuation of consequences of each nature of incident Operating & Maintenance costs

4 An operational cartographic tool Identifying an investment project Low Immediate visual representation of the dt data Representation of zones with a high investment value for safety High Medium Automatic identification of all the facilities via map pointing around pipelines Selecting the street and the gas facilities that need to be replaced

5 CAPEX data (new asset) Selecting assets which will be replaced Validation of the technical and economic input data for Validation calculating the Direct, indirect and induced costs failure rate & corrective maintenance cost of the assets Gains related to the asset management process general factoring in of the full cost, improved visibility of the structure of investments, expected gain in terms of risk management.

6 Gi Gains related ltdto the asset management process 4,000 annual studies and regional medium values CAPEX and Value by Region feedback used for future regional allocation of investments, 25 7 CAPEX (%) 20 Very good equilibrium 15 between investments 10 and level 5 0 CAPEX (% of Total CAPEX) A B C D E F G H 4 7 REGION 18 7 Value Regional 6 Decrease level level 5 Value or change National level efficiency 4 of of investments 3 2 Value local programs Very efficient i 1 program and possible 0 increase of allocation Future developments of GDF GrDF asset management tools implement the principles of the cost/risk analysis for maintenance strategies improve the modelling of forecasts of failures of the gas facilities, refine the input parameters and the operating charges and maintenance costs, and in the long term, achieve a general and integrated decision making solution.

7 Conclusion use the same tools to optimising the efficiency of our investment and maintenance policies at all levels, facilitate acceptance of different allocations of resources in an objective manner, be in position to demonstrate our ability to be a legitimate player using regulated revenues as efficiently as possible develop GrDF asset management tools on the basis of a very operational and pragmatic rationale.
