Tiein Planning In Construction

Tie-In Planning 1. Identify each Tie-In(s) schematic location on P&ID - Process Engineer 2. Review with Piping - Process & Piping Design 3. Create a Tie-In Index (or List) with key information about each Tie-In - Piping Design & Process Engineer 4. Review with Client - Process Engineer 5. Go to the Field to locate physical point of Tie-In - Piping Design/Process 6. Meet with plant personnel and review Tie-In requirements - Piping Design, Process, Plant Operations, Safety 7. Discuss different types and configurations of Tie-Ins - Piping Design, Process and Plant personnel 8. Establish physical Tie-In location point and type - Piping Design & Plant Personnel 9. Define if the line can be shut –down, when, how long, draining, depressuring, steam-out and other safety issues - All personnel 10. Visually inspect the existing pipe. Are more extensive tests needed to determine condition and suitability for the Tie-In - Piping Design and Plant personnel 11. Mark or tag the selected Tie-In point - Piping Design & Plant Personnel 12. Photograph the Tie-In point - Piping Design 13. Draw sketch and take all required measurements - Piping Design 14. Determine locations of all existing block valves, vents and drains - Piping Design 15. Determine the location of all existing anchors and guides - Piping Design 16. Based on selected Tie-In location and type determine if additional vents or drains will now be required - Piping Design, Plant Operations 17. Include new vents or drains (if any) on sketch - Piping Design 18. Insure that this process is followed for all Tie-Ins - All participants 19. Get plant personnel to sign off on all data collected in the field - Piping Design & Process Engineering 20. In the office modify the P&ID as required - Process Engineer 21. Convert all field sketches into appropriate production drawings (Isometrics) - Piping Design 22. Prepare a Plot Plan style "Tie-In Location Key Plan" 23. Update the Tie-In List as required - Piping Design 24. Review all Tie-Ins with Pipe Stress for effect on existing system piping and new system piping - Piping Design 25. Finalize (check, correct and approve) all Tie-In isometric drawings - Piping Design
