Lock-out organization The Project Team has proposed and approved the equipment that necessarily needs to be kept powered in order to assure the safety of workers The works for the cable removal require: The Lock-out Standard and systematic of PS (EPC-ABT) The supplementary and specific lock-out (racks, power RF, Tablx BT, UPS…) The temporary power supply for the basic needs (vide, star-points…) The works for the cables’ removal are framed by 2 VICs, one at the beginning and one at the end of the work. Signatures and formal exchanges of forms for lock-out certificates (first or second stage) during the VICs. The group leaders (owners of each installation/equipment), previously notified through the Memorandum EDMS 1686597, are named lock-out responsible for their equipment.

De-cabling during YETS 17-18 (PS Center Ring) Duration Planning 3 days for Lockout and False floor consolidation (20,21 & 22/12/2017) Surface + galleries (without Ovoid 8) 30 working days needed Ovoid 8 (in parallel with surface): 27 working days needed Pulling 30 cables LIU: 5 working days needed (intervention period TBD) Specific lock-out for decabling project from 20/01  15/02 First Draft The calculations are based on the gained experience in PSB (works in 2 shifts).
