3 OUTLINE OF PRESENTATION Introduction Objectives Job Plan Information Phase Speculation (Generate alternatives) Evaluation Deployment Presentation Implementation

4 INTRODUCTION Electric Panel Factory at Dammam has decided to modify compact substation production line by replacing Oil Ring Main Unit (RMU) with sulphur hexafluoride insulation (SF 6). Replaced Oil Ring Main Unit (RMU) by SF6 insulation

5 OBJECTIVES 1. Replace Old and Obsolete Oil RMU 2. Use SF6 RMU 3. Select the best RMU 4. RMU should be delivered in six lots / 2 year 5. The cost of oil type RMU is 15,000 SR

6 SF6 in RMU SF6 gas is used in electrical power equipment It is insulation and arc quenching medium in RMU

7 SF6 Oil Type of Ring Main Unit

26 Value Study Summary Comprising between SF6 and Oil RMU Reduce the cost of compact substation Easy to install Increase customer acceptance of co S/S Increase the Factory market share RMU`s manufacturer will provided technical support for changing implement the new design Reduce maintenance cost Increase breakdown The difference in price between oil and SF6 is slightly very small

27 Implement Plan 1- How Should it be implemented? The propped RMU from Saudi Lucy will be discussed with factory, purchasing and engineering managers to overcome any road blocks prior to management presentation 2- What should be changed and in what sequence? Within approval the purchasing department should finalize the price and delivery time. Then, the designer shall revise the drawings to meet new approved SF6 RMU. 3- Who should do it? Engineering department and do necessary changes prior compact substation submittal to procurement department

28 Implement Plan 4- How long should it take? Two weeks 5- Any deadline required As per management report forcast 6- Implementation cost, internal house 30 hours for engineering 20 procurement 50. Total cost SR 3000
