Pipe works in the UX85 experimental cavern
Activities related to WORK LOT 1- fixation of the supports for 16 transfer lines (OT included) along the
RB84 side and on top of the vault TX84- installation of the OT transfer lines in stainless steel (multilayer
pipes use to be quoted as an option)- installation of the supply/return OT distribution manifolds
Activities related to WORK LOT 4- installation of pipelines for chilled and mixed water (RB86), demineralised water (RB84), compressed air (both sides) networks, including supports and required equipments
Due to INTEGRATION matters
the detailed activities shall be scheduled and performed during:
JUNE – JULY 2005Paolo Guglielmini TS / CV / DC 08th April 2005
Integration in the SCADA local supervision
IT 3307 – Paragraph 4.2.2.1 “Communication”Four additional cooling systems will also be locally supervised and operated from the
SCADA local supervision platform. These cooling systems are controlled by 3 PLCs, which are also built on Schneider Premium TSX equipment.
These PLCs are not included in the scope of the supply of this Technical Specification. 1 PLC Inner Tracker - Tracker Trigger1 PLC RICH 1 & 21 PLC VELO
The Contractor shall integrate in the SCADA local supervision platform database the process data from these 3 external PLCs.
The Contractor shall develop, test, install and validate on-site the local supervision means corresponding to these external cooling stations...
Provided commissioning of the cooling systems whose PLCs shall be integrated:
end of FEBRUARY 2006
