  7. 7. Overall Plot Plan 7
  8. 8. Descon Scope Areas 8  Sour Water Area  MEG Regeneration  Condensate Stabilization (Compressor Area)  Flare K.O  Effluent Treatment  Inlet Facilities Area (Slug Catcher)  Cooling Tower Area  Flare  Main Sea Water Line (42”-FRP)  86” Cooling Water Line
  9. 9. 9 2. SPOOLGEN OPERATIONS
  10. 10. Organogram of Spoolgen and My Responsibilities 10 DESCON Planning& FEDC
  11. 11. About Spoolgen 11  Intergraph Software for Automatic Spooling and Joint Marking  Input File is IDF File generated from PDS or PCF File generated from SP3D Software  The outputs  CAD Files (Spool drawings for Fabrication)  Weld/Joint Information  Material data for accurate material allocation  Site Assembly/Bolting Information
  12. 12. 12
  13. 13. Advantages 13 Planning and BOQ Reduces Manhour Better Material Allocation and Control
  14. 14. Spool Drawing Preparation and Issuance 14  Piping Isometric Review and Joint Marking  Preparation of Input Data for Spoolgen Software  Spoolgen Operations (FW Marking, Sheet Split)  Output files Generation (CAD and Text data)  CAD Drawing Along with Data issued to Subcon  Maintaining Index and Issuance Control Sheets
  15. 15. Check list and Spoolgen Output 15  Check List Used by JGC  Joint Number Legends  Sample Spool Drawing  Sample Weld Info File  Sample Material File  Sample Assembly File
  16. 16. 16 3. CMS AND SPOOLGEN INTERFACE
  17. 17. Construction Management System 17  JGC In-house software for complete Construction Management CMS Materal Control Test Pack Control FS Control System Welding Control Contruction Planning
  18. 18. 18 3D (PDS etc.) MACS REQ PCOM ETRS / MTCS SPOOLGEN CMS REQ PO Spool Piece wise Material Data (LOM) Weld Joint Data Assembly Data PO/Shipping Data (MSR Data) E(3D) C(CMS) Spool Piece Dwg Spool Dwg P(PMS) ISO wise Material Data(LOM)
  19. 19. 19 4. YS/FS CHANGE SHEETS
  20. 20. YS/FS CHANGE SHEETS 20  Change Sheets Preparation for all Isometrics (Engineering) Revisions  Automatically generated from CMS  Input for YS is “*.b” files  Input for FS is Manually/Site Mark-up  All spool drawings are updated as per the isometric revisions  Joint Additions, deletions, and cut and re-welds  YS Revision Check List  Sample YS sheet  YS/FS Tracking Sheet  Finally to DHT for Issuance to Subcon.
  21. 21. 21 5. Site Spool Drawings Revisions Work
  22. 22. Site Revisions Work 22  All Changes due to site work other than Engineering Change  Joint Change Request Form (JCRF)  Shop Fabrication Errors  Site Installation Errors  Joint Category Change  Change due to Construction Sequence (Hydrotesting)  Cut and Re-weld due to RT Failure  Joint added due to Random Pipe Length  Change due to seam Weld orientation
  23. 23. Sample Site Revision Drawings 23  Sample 1, Hydro Testing  Sample 2, Change Due To Random Pipe Length
  24. 24. 24 6. Field Engineering Support
  25. 25. Plate Thickness for Hydrotesting 25  Blind for Hydrotesting of 36” Line  Mating Flange = 36” 600# ASME B16.47 Ser. B  Material A36  Design Pressure = 126.3 barg  Blind Thickness as per ASME Sec VIII Comes out to be 145MM
  26. 26. PAD Overlapping with Seam 26  For 52” &56” lines, R.L received 9M instead of plan 11M  Drawings need to be revised as there were additional joints
  27. 27. Calculation of Neck of PAD 27
  28. 28. Double PAD for AIV Lines 28
  29. 29. FTR (Field Trouble Record) Issuance 29  FTR was issued by Subcon to JGC for any kind of problem related to Fabrication/installation of Piping  Sample FTR
  30. 30. Field Trouble Isometrics-1 30
  31. 31. Field Trouble Isometrics-2 31
  32. 32. Field Trouble Isometrics-3 32
  33. 33. Field Trouble Isometrics-4 33
  34. 34. Spool dwg Hold and Release 34  Spool Fabrication, Installation, Material Issuance, and every thing got hold for YS Drawings  So if there are many such drawings Shop cannot proceed Fabrication  Welders/Fabricators can sit idle in severe conditions if there are too many revisions viz. not acceptable in any case.  Since all changes are not related to shop fabrication, so shop can proceed fabrication for such cases  So, we provided information of spools that shop can proceed fabrication without any impact by revision
  35. 35. Spool dwg Hold and Release 35  Spool Drawing With Impact on Fabrication  Spool Drawing With No Impact on Fabrication
