  2. Requirements Allocation

  3. Construction sequence

  4. Flow of Requirements

  5. SE Process for INFRA

  6. ICD – 3 Iterations

  7. ICD – 3 Iterations • Iteration 1 (DRAFT1) • Part of Requirement Definition (by RR) • Concept Driving IF requirements • Iteration 2 (DRAFT2) • Agreed ICD between INFRA and other elements • Part of Preliminary Design (Part of PDR pack) • Iteration 3 (FINAL) • Signed Off at conclusion of PDR process • Formal change control for detailed design

  8. Vessel and Payload

  9. INFRA ICDs with other elements

  10. ICD INFRA and DSH • IF Lead = INFRA • IF Boundaries • Array Layouts (SKA1-MID, Survey) • Dish construction Facilities • Antenna Foundations • IF Types • Foundations Physical (Structural, cables) • Dish Electrical Power Budget (Electrical) • Power Backup & UPS (or not) (Reliability) • Earthing and LP • Staff requirements (ILS)

  11. ICD INFRA and DSH... • Issues • Final Array Layouts • Loadings and Mechanical Interface • Responsibility for Bolt cage assembly (DISH?) • Power per antenna • Fibre / sleeve IF to DISH (INFRA or SaDT) • UPS for stowing (Dish or INFRA?) • Separate enclosure for Survey (RFI shielded) • Assume 10% of array can fail?

  12. Dish - Bilateral • ICD lead =

  13. ICD INFRA and LFAA • ICD Lead = LFAA / INFRA (AUS)? • IF Boundaries • Array Layout • Array Foundations • On site Bunker • IF Types • Physical • Antenna Electrical Power (Electrical) • Cooling • Power Backup (Reliability) • Local infrastructure

  14. ICD INFRA and LFAA.... • Issues: • Power system design • Compatible array config between DSH and LFAA • Power requirements per antenna • Solar Power • Impact on buildings

  15. LFAA - Bilateral • Lead = • Bunker, 256 racks + a few • Fibre management (RF over Fibre) • Integrate correlator ? Maser? MGR? In bldg • 500 000 Fibres (2 per antenna) • Fibre design = LFAA, who supplies? • Cable buried ? Or conduit vs phase stability (MRO tests)

  16. LFAA-INFA • Solar power for each 25k antenna , Battery tech? • Total 2-3 MW • MRO = 80 racks (Double screen),80 single screen • ICD doc

  17. ICD INFRA and SaDT • ICD Lead = INFRA • IF Boundaries • Racks in Processing Facilities / containers • Fibre buried / cables • Fibre on Power Lines? (Physical) • IF Types • Space if facilities (No racks, size) • Power & Cooling • LAN / Data Interface (Data) • Staff requirements (ILS)

  18. ICD INFRA and SaDT..... Issues • Location of Super computer centre (RSA) • IRD or ICD for SaDT and INFRA • Use of existing Fibre links (Buried & Overhead) • IF / cut over from Integrated LAN (RSA) • Environmental Data Document (SKAO?) • Special requirements for Masers? • Telephone data responsibility? • BMS data over network

  19. ICD INFRA and CSP • ICD Lead = CSP? • IF Boundaries • Racks in Processing Facilities / containers • IF Types • Racks (Qty, Space, Mass) • RFI screening • Power Type and Load • Power Usage and Backup / UPS (Reliability) • Cooling type • Cooling redundancy (Reliability)

  20. ICD INFRA and CSP..... • IF Types.... • LAN / Data interface (Data) • Access control / BMS (Functional) • Staff Requirements (ILS) • Issues • 250 racks for Pulsar search (RSA) • Rack requirements for LFAA/Survey (AUS)

  21. CSP – Bi Lateral • Space, Power, Cooling • Survey ~ 100kW,MID ~ 100kW, LFAA ~ 50kW • Confirm UPS requirement (AUS) • 3phase AC 400V interface • P search = 1MW = 50 racks (100m distance, spigot) • Air or Liquid cooling for P search ? • AUS = Liquid, RSA = Air • Fibre racks (overhead 400mm) • RFI spec TBC (100dB)

  22. CSP - Bilateral • Process • AIV to spec • growth path • Cable marking etc • Doc of what we have (INFRA) – Before T0 • Space, power, cooling • RFI screening (RFI ITT) • Smoke, gas, access/CCTV, ESD (interlock?) • Standards • ICD Doc (CSP) – T0-12W • Limits (Power) Agreed doc • RR to PDR (update via CM) • PDR to CDR (update via CM)

  23. ICD INFRA and SDP • IF Boundaries • Racks in Processing Facilities • IF Types • No Racks in facility (Qty, Size & mass) • RFI screening • Power Type AC/DC/Voltage/1 or 3 Phase • Power Usage & Backup / UPS (Reliability) • Cooling type • Cooling redundancy (Reliability)

  24. ICD INFRA and SDP • IF Types • LAN / Data interface (Data) • Access control / BMS (Functional) • Staff Requirements (ILS/Con Ops) • Issues: • Space requirements for LFAA/Survey (AUS), • User supplied equipment space • Location of SDP (On site, off site)

  25. ICD INFRA and MGR (TM) • ICD lead = INFRA • IF Boundaries • Racks in Processing Facilities / containers • IF Types • Racks (space, size, mass) • Power Type & Quality • Power Backup / UPS (Reliability) • Cooling redundancy (Reliability) • LAN / Data interface (Data)

  26. ICD INFRA and MGR..... • IF Types..... • Access control / BMS (Functional) • Staff Requirements (ILS) • Issues

  27. Existing facilities – SA Site • KAPB • 130 racks in screened facility • 640kW cooling • 5kVA average per rack • Flexible feed to rack (1,3 ph A and B bus) • 40 Fibre cables entering building • 150 Fibre penetrate RFI screened room

  28. Existing – SA Site • Overall Power • 2.5 MVA fitted • 5 MVA with full UPS (N+1) • 6-7.5 MVA from current grid • Sheds • Size of shed vs dish size • Support base / workshops • Derived from Con Ops
