  1. KING FAHD UNIVERSITY OF PETROLEUM AND MINERALS DEPARTMENT OF CONSTRUCTION ENGINEERING AND MANAGEMENT TERM PROJECT PRESENTATION CEM – 512: Value Engineering Ring Main Unit SF6 BY ABUL KARIM AL SULAIS

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

  3. 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

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

  5. SF6 in RMU • SF6 gas is used in electrical power equipment • It is insulation and arc quenching medium in RMU

  6. SF6 Type of Ring Main Unit Oil

  7. Compact Substation

  8. Compact substation Layout Transformer MV LV

  9. Infromartion- Requirment • Type- tested • Independent of climat • Maintenance - free • 15 KV , 630 Amp , 60 HZ ,SF6,21 KA/sec • Hermetically -sealed welded switchgear enclosure • Compact and clear design • Short Delivery Period

  10. Encapsulated, climate proof, Easy accessable , etc. Infromartion- Requirment maintenance free compact Easy cable instalation Easy cable installation

  11. Information- Data • Quotations • Catalog • Competitor

  12. Information- Cost Data

  13. Function Worksheet Why To install RMU in Compact S/S To have good market share Function Buy 500 RMU Select RMU How Select RMU

  14. Identify Present Function • What dose it now do • Verb noun • Feed Transformer • Link Load • Used Oil insulation • What must it do • Verb Noun • Improve marker share • Reduce Maintenance • Easy operation & installation • Increase Customer acceptance

  15. Analysis Phase- Ideas • The most used RMUs in KSA • ABB • Siemens • Merlin Gerin • Saudi Lucy • Alstom • Hoeco • Ormazabal

  16. Function Worksheet • Function : • Re Design Compact substation using SF6 RMU • Why : • To be competitive in the market • How • Select SF6 RMU

  17. Reliability Replacement Cost Probability of Implementation Reliability Time of Implementation Total Rank

  18. Idea Comparison

  19. Weight Evaluation

  20. Weights for Evaluation

  21. Low “life cycle costs“! independent of dust, animals and climate insensitive to failures maintenance-free Salvage value after 15 years easy to operate safe for people compact low building and real estate expenses

  22. Life Cycle Analysis for 500 units

  23. Life Cycle Analysis • I = 8% N= 15 • P/A= 8.5595 P/F = 0.3152 • P- Original = 9,546,298 • P-ABB = 11,121,170 • P- Siemens = 11,657,095 • P-Saudi Lucy = 9,501,895 • Choose Saudi Lucy since it is the lowest

  24. Savings • Original : • Total SR 9,546,298 • Proposed Saudi Lucy • Total SR 9,501,895 • Saving = 44,403 # 0.465 %

  25. 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

  26. 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

  27. 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
